HOW to GET RID of POWDERPOST BEETLE

There are 4 different types of powderpost beetles: Lycid, Bostrichidae, Anobiidae, and Creamycidae. The stage of the beetles where they do the most damage is the larvae. The larvae of all the beetles will reduce wood to a mass of very fine, powder-like substance, but the adults do very little damage.

Adult powderpost beetles appear once a year, usually during June. When the adult powderpost beetle appear in June, they leave small holes around the size of a pin in the surface of the wood and some leave a hole about the size of a pencil lead.

Lycitdae or also known as True Powderpost Beetles, are extremely small and less than 1/4′ in size; powderpost beetles Lycidae are flat and reddish brown to a black color. Larvae are white, cream colored and have dark brown head. The larvae of powderpost beetles (Lycidae) create tunnels in the wood as they become pupae and as an adult when they come out of the wood, the hole is the size of 1/32-1/16′ pinholes.

Anobiidae (Furniture and Deathwatch Beetle) attacks building timbers that are in poorly ventilated areas where there is moisture. Anobiidae powderpost beetles got the name Deathwatch beetles because from the ticking sound that the adult makes inside the infested wood. You will be able to hear them at a quiet night. These powderpost beetles can range in a size from 1/32-3/8′ long but the ones that attack the structures are around 1/8-1/4′ long. The anobiidae powderpost beetles are elongate and cylinder like. The first body segment looks like a hood which hides the head.

The Long-Horned or Round-Headed powderpost beetles feeds and lives in dead or dying trees, but they can also feed on living trees. The main reason on why the Cerambyciae powderpost beetles can come into the house is from firewood brought inside during the winter season. Old House Borers are found in older building but are becoming more common in newer buildings 10 years or younger. The adult old house borer powderpost beetles are brownish-black to black, semi-flat, and about 3/4-1′ in diameter. The exit holes that these powderpost beetles make are oval and around 1/4-3/8′ in diameter. The damage will have already occurred for several years before you might even notice the exit holes.

INSPECTION

The powderpost beetles are found in stored lumber, rafters, joists, finished wood, and furniture products and pinewood. Also starch-rich sapwood of large-pored hardwoods i.e. ash, hickory, oak, walnut and cherry trees and structural timbers

CONTROL METHODS

Prevention:
There are several procedures to take to help prevent beetles from infesting wood.

  1. Inspect wood prior to purchase
  2. Use proper air-dried wood
  3. Seal wood surfaces
  4. Use chemically treated wood
  5. Use good structure design i.e. ventilation, drainage, and proper clearance between wood and soil to decrease the moisture content
  6. Use the central heating and cooling systems also to speed up the wood drying process.
  7. Sand and varnish the non infested wood
  8. Items that are held in value should not be stored in buildings outside such as in barns or sheds because these types of buildings are most of the time infested with powderpost beetles.
  9. If it is possible remove the infested wood form the premises.

TREATMENT METHOD:
As we described above, powder post beetles will leave holes when they inhabit the wood and will lay eggs because of this, we suggest that you use Timbor (TIMBOR INSECTICIDE & FUNGICIDE) which is a powder that you will mix with water to be used as a spray. You will mix one lb. with one gallon of water. Timbor (TIMBOR INSECTICIDE & FUNGICIDE) can possibly stain so it is not suggested to be used on furniture. Timbor should not be used on painted, varnished or sealed wood, or cellulose material. If the wood is drier than the normal moisture content then you need to apply by brush or spray two applications of the solution. You will spray this product using a hand sprayer (CHAPIN SPRAYER). Boaracare (BORACARE TERMITE) is a liquid that reacts faster than Timbor, it is used the same way as Timbor. If your furniture is severely infested, then it is recommended to fumigate it in a fumigation chamber, however, only by a licensed professional. If it is not severely infested, use aerosol products (PRO CITRA DL , CY-KICK AEROSOL) to spray only in places where you think that powderpost beetles have laid their eggs.

    A very useful article indeed, and real do-it-yourself.

  2. 2

    How to treat infestation of post beetles in hardwood floor in house less than 5 years old?

  3. 3

    It kind of depends.
    Do you have a crawl space? In that case, you have to start treatment down there.
    We recommend using Boracare or timbor to be used under the floor.

    If you only have small spot of infestation,
    you can use aerosol products for the spot treatments.
    Of course, treating inside the source of problem will definitely give better result, though.

    If you have more questions, please e-mail me at info@pestmall.com
    and tell me more in detail how the infestation is at your home.

  4. 4

    I have a new (~2 yr old) oak timberframe house and have discovered active powder post bettles in a beam. The beams are coated with linseed oil. Will the treatment be sucessfull if I spray it on without sanding? Will it darken/stain the wood? I have found other holes but have not seen any activity. I was told that these are probably old. How do I know the difference between an old (inactive) and a new holes. I am watching for sawdust. Is there any other way to tell?

  5. 5

    It seems you have fairly good idea what to do.
    I’m very impressed!

    Sad thing is that there’s no other way to differentiate the active holes
    from inactive ones besides looking for debris / sawdust.

    About the treatment, we recommend that you sand the wood to remove the coating.
    That’s the best way. Another way is if the holes are on the surface
    (meaning they are not covered with coating / painting), you can do the surface treatment
    and the treatment will soak into the holes. But this method is not as effective as the other one.

    Let us know if you have other questions.

  6. 6

    We have a log home of rough poplar over 15 yrs old. Noticed the dust late last fall. We added a new addition of treated pine less than 3 yrs ago and completed stripped the entire house and restained this summer. What can I do?

  7. 7

    It depends on how bad your infestation is. If your infestation is not too severe, and you only see a few holes, you can just go ahead and use aerosols like Pro-Citra or Cy-Kick. However, I normally recommend people to use Timbor or Boracare.

    You actually have to use a sprayer with it (after mixing with water, of course),
    and it is better to remove any paints or coatings on the surface.
    What you want to do is completely soak the wood of the infested area with the solution.

    But before anything, do an inspection first. If your infestation is not severe,
    I’ll just say go with Cy-kick and spray it into the holes. It will leave residues
    and when the powderpost beetles start climbing out, they will come in contact
    with the residue and die instantaneously. However, with severe infestations,
    it will not be sufficient.

    I wish you a good luck.

    great info. thanks Brought furniture from very humid climate to very dry climate Noticed what looks like deathwatch beetles. Have holes everywhere,and yes I can hear what sounds alot bigger at night. Noone in my area seems to be able to deal w/this huge problem. Outside logs also have tons of holes. Help gumpy7@cox.net

  9. 9

    Well, I am facing an extensive infestation of what looks like carpenter ants and powder post beetles. I have been in my log cabin for almost two years(it was built in the 80’s)…The gutters had been leaking(previous owner) and had saturated the bottom log and sill oft he cabin…as we renovate we are finding the damage is extensive…and now I am seeing the pinholes and “eaten” wood…We really want to handle the problem ourselves, but how do we know we are treating the whole infestation…and if we call a professional..who do we call and how can we be sure they are not taking advantage…please help..very stressed about bugs!

  10. 10

    Usually, we would recommend Timbor Insecticide and Fungicide, but since it is an infestation on your furniture, we would advise not to use Timbor Insecticide and Fungicide because it could leave a stain. We recommend that you use Boaracare (BORACARE TERMITE). It is used for the same purposes as Timbor Insecticide and Fungicide, but it reacts faster. You would have to purchase a hand sprayer (CHAPIN 1 GALLON SPRAYER) to distribute Boracare onto your furniture. If the infestation on your furniture is severe, it is recommended to seek a licensed professional to fumigate it in a fumigation chamber. If the infestation is not severe, use aerosol products (PRO CITRA DL BOTANICAL INSECTICIDE, CY-KICK AEROSOL) to spray into the area where it is assumed the powderpost beetles have laid their eggs.

  11. 11

    This sounds really bad. Basically, we don’t know how long the cabin has been infested.
    The problem with log cabin is that it is perfect place for wood-destroying pests like carpenter ants,
    powderpost beetles, termites, and carpenter bees. Logs are often not treated, so these insects find it easy to penetrate.

    You would have to replace the logs that are severely damaged to the point it will be hazardous to any people inside.
    If you think you can salvage much part of the cabin and you really do not need to replace the logs, here’s few things to understand.

    Basically, there are four types of wood-destroying pests, as mentioned above.
    Out of these four, termites and carpenter ants will cause the most severe damages, as they dug tunnels inside
    a wood structure. Powderpost beetles and Carpenter bees will make holes on the surface, about 1/2 inches to 2 inches deep.

    Termites, you’ll have to call the termite controls. It’s really difficult for individuals to control them.
    As for as others, here’s what you can do.

    For carpenter ants, I recommend that you use Carpenter Bait Kit.
    It contains Advance 375 A Ant Bait and Maxforce Carpenter Ant Bait Gel.
    You might want to use bait trays for Advance 375 A Ant Bait. As for as Maxforce Carpenter Ant Bait Gel,
    just squeeze small amount of the gel (about 1/2 size of a person’s finger nail) on multiple places each time you apply it.
    where you have located the Carpenter Ants. Depending on how big the carpenter ants colony is,
    it will completely destroy the colony after multiple applications.

    You might want to use other products like Masterline Bifenthrin (which also kills termites as well).
    It will not only kill Carpenter Ants, but also Carpenter Bees as well.

    For Powderpost Beetles, use Boracare. It will penetrate into the wood, and kill the Powderpost larvaes.

    You’ll have to mix these two products with water and use sprayer and apply directed onto the surfaces of infested areas
    or on the insects. It will also leave residues on the surfaces of treated areas, which will continue to kill pests
    after it’s completely dried up to 3 months.

    When using a pest control company, and also to know whether you are treating the whole infestation,
    you really have to do good inspection. Again, Carpenter Ants and Termites will dug tunnels.
    Carpenter Bees will make a finger-size hole, and Powderpost Beetles will make tiny holes all over the places.
    For Carpenter Bees and Powderpost Beetles, wherever you see the holes, that’s where the infestation is.
    For the other two, you’ll have to remove a piece of the outer layer of a wall (in your case, you’ll have to cut it out
    from the logs that seemed to be infested. And since each log is separated, that can mean that you have to
    do it for each single one of them. But, if you see that one side is infested, and the other side the first log
    you inspect is not infested, you may be safe to leave that side untreated. I’ll say inspect anyway,
    but I know that’s a lot of work for you)

    When calling professionals, you’ll have to check after they treated to be sure that they are not taking advantage.
    I would trust big companies because for them, their reputation will make it difficult to do it otherwise.

    I wish you a good luck, and let us know what happens.

    I have a very old ( about 140 years) farm house with log support beams in the bassement. The logs have powder post beetle hole but the inspector said he could see no activity at the time we bought the home. I now have some damage in my bathroom wher moisture collected on the window. Will it be effective to spray the basement logs or is it too late? I cannot afford to have the entire house fumigated. Thanks! L Gronevelt

  13. 13

    Hello L Gronevelt,

    I would recommend using BoraCare Termiticide for your support beams in the basement as long as it is untreated wood. BoraCare is very effective with the longest residual time for the protection and elimination of powder post beetles.

    For damages indoors by powder post beetles, I would recommend that you do a spot treatment or surface treatment of the infested area with the BoraCare. You cannot do a broadcast treatment indoors. Wait until it is dry to come in contact with the applied area– give it 24 hours.

    If you want extra security. After you have applied BoraCare on the untreated wood, finish it with a polish. BoraCare’s product label states that it has a residual time that lasts for a life time. If you have any other questions, feel free to contact me again. Thanks.

    I have 1926 Tudor open porch with a powder post beetle problem. It is a highly peaked roof with painted wood beams. The beams with pin holes are reachable and I could treat them–but with what? I don’t know if I could reach the peak. Would the infestation move to higher ground if I treated the lower beams. I do see dust and holes but it looks like some major munching has been going on. Could there be two different problems?

  15. 15

    Hello,

    The best product I can think of for you, or at least the most powerful stuff, is the BoraCare Termiticide.
    It targets powder post beetles as well and is known to be very effective against them.

    I only recommend the BoraCare Termiticide, however, if the wood you are applying on is unpolished wood.
    If it has been polished, I’d recommend sanding it down, applying the BoraCare Termiticide, and polishing it back up.

    You can also use the Crack & Crevice I if you do not wish to go through all the work involved in applying BoreCare Termiticide.
    You would basically inject a straw into the aerosol opening and apply into the holes made by the powder post beetles. I would recommend you do a full treatment all the way up to the peak for security and prevention.

    After I submitted my original problem,Ihave had an entomoligist identify carpet beetles (positively) also powderpost/deathwatch probability. Another professional identified Sawyers. Sooo,I have begun taking up all carpet the concrete below (radiant heat) has wood surrounds that look crumbly.. Now I’m still leaning towards boracare and also the spray. Wht do you suggest? And do you sell Dynamite??!! This is frustrating..

  17. 17

    I have powder post beetles and wish to treat with Bora-care. Is it as effective to spray at this time of year as it is in the spring, as long as the weather is warm enough?

  18. 18

    Hello,

    Bora Care is an excellent product to use because it has got to be the strongest stuff for wood boring insects.
    The manufacturer states that it has a residual time for a life time.
    If you were to apply it now, it will definitely be effective until next spring!

    Hi, after doing some research online, I believe I have powderpost beetles in my new oak hardwood flooring. The infestation is small 4″ x 10″, but am getting about 2 new hole a day. My thought to get rid of them without replacing part of the flooring is to drill 4-6 1/32 holes and use a suringe (spelling ?) to insert the Bora Care solution.
    Do you think this will work? and Where can you buy Bora Care products?

    Thank You

  20. 20

    Hello! Powderpost beetles can be a pain in the neck! Actually, I don’t think that spot treatment will work for Powderpost beetles. The reason you see the holes is not because they penetrate the wood from the outside, but they lay eggs inside the wood and they eat from the inside out. The Bora Care solution is effective but not in that manner. It’s the most effective to spray the entire area or paint it on. You can dilute the 1 gallon solution with water and you use less water to dilute the solution depending on how heavy the infestation is. The product label on the back of any product should show dilution ratios. I hope this helped you! Good Luck!!

    I have powderpost beetles in my honey locust firewood. Will they stay in it all winter or once they become adults ,do they leave?

  22. 22

    Hello! Actually, for lumber and wood, yes, Powderpost Beetles are known so survive whole winters and will stay. They lay eggs, hatch and will live in the wood.

  23. 23

    I have just lost two of my aborviti and noticed dozens more dead in the neighborhood. I’ve inspected the trunks and there are many pinholes and larvae beneath the bark. Most of the adjacent trees show no signs. Can the Tim-bore be used on live trees and is the best product to use to prevent attack? Has anyone had any luck painting the trunks of live trees? How completely to you need to paint them to allow them to survive a mild attack?

    thanks, mike

  24. 24

    Hi Mike,

    I’m sorry about the losses of your arborvitaes. The pinholes and larvae beneath the bark are probably a type of beetle that is infesting the arborvitaes. Timbor would probably be the safest product to effectively use for this treatment. One 1.5lb bag of the Timbor mixed with one gallon of water and sprayed around the areas needed should do the treatment for your arborvitaes.

    Good luck with the treatment!! (:

    I have a friend who has a powderpost infestation in a cupboard near his kitchen sink. The inside of the cupboard where the pinholes are along with the frass are painted and possibly varnished on top of the paint. I am curious if I use timbor or boracare on this situation will it penetrate this surface? Or what other meens of application will I have to pursue?

  26. 26

    Boracare or Timbor is the most effective when the wood is sanded down or unfinished. The idea for powderpost beetle control is to let the insecticide soak through to the tunnels of infestation. If it does not soak through, then you can only target the adults that are already outside of the tunnels, however, the larva thats inside will not be effected. He needs to sand it down, treat the wood, and then finish or varnish the wood again. That is the most effective way of control.

  27. 27

    I have what I think is an active infestation of powderpost beetles in my hickory floors. The floors where installed in Jan. 2007. Our first dust covered pin holes where discovered in March 2007 and the problem is continuing to get worse each year. This spring we get anywhere from 5-20 new holes each day throughout our downstairs area of our home, 1200 sq. ft. We also find 2-4 beetles on the floor near the exit holes, some seem to be alive others dead. We consulted a hard wood floor company who said the beetles can’t live in this area I live in the Sacramento region of California; it’s too hot and dry. They also said the wood looses it’s moister each year and the beetles will eventually die out as the wood continues to dry out. What should we do? Continue to wait? We love our floors, but it seems like our problem is growing bigger each year not ending. Help…

  28. 28

    Hi Amy,

    You may want to try using Boracare. Boracare has the capability to penetrate through unfinished surfaces of wood. However since it is flooring you are having problems with I assume it has a finished surface so Boracare will only remain on the surface of the floor but will still be efficient in helping you eliminate the infestation to its minimum. Good luck!

    Hello. Sorry that this is a little late on post.
    We just moved in to a retirement building that is now an apartment complex. The wood looks very old and thin, we do seem to have a little bit of a beetle problem. After reading I’m pretty sure it’s a Powderpost problem. We can’t seem to find WHERE they come from, all we know is they show up in one main area. Each room in the complex is pretty small so.. There’s pretty much the kitchen / living room, and two small bedrooms and a small bathroom. They are pretty much all about 20-30 feet away if that. We’ve noticed that they seem to come out more so when it rains, but they have come out before. At first we thought it was the hole in our screen door, but after leaving that closed for many days and still having this beetle issue, we knew it wasn’t that.
    I don’t really want to go spend money on things that won’t cure this problem if I don’t know what it is.
    I can’t seem to find an exact picture of this beetle anywhere, all I can say is it comes pretty darn close to the Anobiidae style beetle.
    Any help or input would be great. I could also upload a picture and provide a link if necessary.

  30. 30

    Hi Bryce,
    It does sound like you probably have a powder post beetle problem, but I don’t want to say I’m 100% certain of that yet. I would love it if you sent us a picture to info@pestmall.com so we can try to identify your pest for sure for you. If in the time that it took for me to reply, you confirmed that you do in fact have powder post beetles, then I would recommend using either Timbor or Boracare to treat the entire wood area where the beetles seem to be coming in. You may also want to let the owner of the complex know. Powder post beetles can be as bad as termites and can also affect other rooms, so this problem should be treated ASAP.

    Hi, I recently bought what I had thought was a finished mask in Mexico. I got home and started to notice “sawdust” under the mask where I had placed it and upon inspection have found severl small holes. I now suspect powder beetles. How can I get rid of them. Can I use heat or cold? Should I be worried about them getting into the wood parts of my house such as floor boards and framing? I live in a climate that does get as cold as -40degrees C in winter.Thank you so much for your help!

  32. 32

    Hi Melissa,
    Well, that’s not a very fun souvenir, haha! Thankfully, powder post beetles generally aren’t as problematic as termites or carpenter ants. You should still keep an eye out for any beetle activity in other wooden areas of your home though; they can travel. I personally don’t know what temperature powder post beetles die at, but Boracare will do a good job killing them for you. Try looking up what temperature they die at online! Good luck!

  33. 33

    Hello, I recently pulled my log bed frame out of storage and set it up in my house. I started hearing a weird noise coming from 3 posts at night and noticed some fine saw dust on the floor.After research I believe this to be the death watch beetle. There is varnish on the entire frame. Is there anything I can do to kill these critters without removing the varnish?

  34. 34

    Hi Robert. Unfortunately, the only way to thoroughly treat for wood-infesting insects is to make sure the wood is bare or drilling holes into the wood. That will ensure that the wood treatment will soak through the wood and not stick to the surface.

  35. 35

    Whoa! do we need help! We’ve lived in this house for 45 years (it’s probably 55 years old). It’s made entirely of fir and redwood which was cut and milled off the property. The powder post beetles have always been in the fences, out buildings etc…’til now! They’re dropping out of the (open ceiling) beams into and onto everything. Short of pulling the roof off and laying down new beams I can’t see that there’s a solution. Your input, please!

  36. 36

    Well, in order to make sure that the insecticide soaks through the wood, you do need to make sure the wood is bare. It is difficult to treat beams though unless you are getting it professionally treated. You can also look into fumigation, however, there are restrictions and regulations on fumigation treatment processes. If you can find a way to get the insecticide to soak through the wood beams though, Boracare or Timbor are both great products to treat for powderpost beetles.

  37. 37

    We just bought a used table (Indian made) that is infested with wood beetles. We love the table and so are really sad about this – as well as about the cost of the table and the cost of fumigation – and the possibility that even fumigation won’t work.

    We don’t know what to do. There is a 7 and a 2 year old in the house and a newborn due very soon so we don’t want to do anything that would be harmful to them.

    Fumigation is an option but is it OK to bring it back into the house with the kids afterwards? Does the poison gas stay in the wood – this is a dining table.

    I was wondering if orange oil works at all?

    Or what about fumigation and then orange oil to stop them returning?

    We live in Southern California.

    Thank you

  38. 38

    Hello Michelle, Fumigation is very expensive but it is effective if done properly. Also, most insecticides that are used for fumigation does not leave a residual. That means that once the insecticide has cleared, it is no longer effective. As long as you give it ample time after the fumigation for the chemical to dissipate, then it will be okay for you to bring the table back inside the house.
    Orange oil is said to be effective against many crawling insects. As you may know, it is a more organic or natural type of insect killer so you may be interested in that. We only have 1 spray though that has an orange oil based active ingredient but that is just a knockdown residual and will not penetrate the wood. It will also not be an effective preventative for wood beetles. If you have any other questions, you can always call us at 1-800-788-4142.

  39. 39

    it seems we have beetles in our hardwood flooring that is 3 months old and is a new home. our floors are stained and varnished what do you recommend we use to get rid of these insects. they are in the entire home not just one spot
    thank you connie

    Hi,

    I live in a mountainous area of France (850 meters above sea level). We’ve recently renovated an old barn and now live in it. I’ve just noticed some fine powdery dust on the floor below one of the original oak beams. I can see tiny holes in the beam but there are holes in most of the beams anyway (they’re 200 years old). They were treated during the renovation. I see on the net that most wood boring insects are active during the summer months. Right now it’s winter and temperatures falling to -2 at night. So, is this likely to be some sort of woodworm problem at this time of year? Thanks for any help.
    Frank

    Unfortunately, for wood infesting beetles, you have to treat the wood directly. In order to do this, treatments with insecticide like Boracare and Timbor must be allowed to soak through the wood. You can drill holes and inject or paint it on or you will have to sand down the finishing so that the wood is bare.

  42. 42

    Hello,

    For wood infesting beetles, if the temperatures are warm enough and there is enough moisture, they will begin to emerge or stay active. This can prove to be a problem indoors because the temperature is usually maintained at a constant warm temperature. You should use Boracare or Timbor to treat for wood infesting beetles. If you have any further questions or comments, please feel free to contact us again.

    HELP! I had my house spray for termites and know they say I have carpet beetles. I fist notice them in my window and sliding doors. and know they are upstairs in two of my rooms. Also can they be harmful to people and animals. I am so worry about this. Also if your house has been treated for termites I though it would kill any insect in my walls of my home. please help. I am going nuts.

  44. 44

    Hi Laura, Termites and Carpet Beetles are totally different insects. In fact, although pest control is a broad term, many professional companies separate termites from the rest and will call it termite control because the methods of treating them are entirely different. Also, treating for carpet beetles is not difficult, but sometimes it may require setting up traps as well as spraying. Carpet beetles will not harm people and only the animal based fibers like wool fibers and etc. Over an extended period of time though, they can really damage carpeting, upholstered furniture, and clothes, so it is important to treat them as soon as you can. If your pest control technician has treated for termites, although it may kill the carpet beetles if the beetles come in contact with the treated area, it is not totally effective for carpet beetle control. Also, most termite control products are meant for outdoor control or is specifically labeled for termites. You will have to use a different insecticide for carpet beetles. If you have any further questions or comments, please feel free to contact us again.

    I have 2 triangular shape tennis ball size sawdust piles on two corners on two shelves on the garden window that hangs partly outside in my bedroom. I noticed the piles a few months ago and swept them up, but they just came back. I now see what looks like black dots of bug droppings mixed with the sawdust all over the windowsill. I do see a few tiny winged bugs along the wall edge and have noticed a few small beetles on the floor and in the nearby bathroom. At first I thought it was termites, but after researching think it could be powderpost beetles. I am just wondering if it could be termites both. I live in an apartment and it is just freaking me out, cuz I wonder if they can get on me when I am sleeping and on other things of mine. I have left an urgent message with the apt after hours. I wonder if I should just keep cleaning up the sawdust and get por citra or cy-kick aerosol to use regularly, after the apt. complex does their thing if it comes back.

  46. 46

    Hello Aly,
    Tennis ball size sawdust piles are quite amazing. I’m not sure if they are from either termites or from powder post beetles. You should definitely get an inspection done by a professional so that they can accurately identify the pest for you and then treat accordingly. Cy-kick is a good general bug spray but it has no residual (or a very a short one at least) and so you will have to apply it once every few days if you choose to use Cy-kick. That is the same for ProCitra. It would be the best to identify the pest first and then treat the pest infestation according to what you find out because you will be able to use better products to totally eliminate the problem. I hope that helped. If you have any further questions or comments, please feel free to contact us again.

    Hi,
    I am really impressed with the depth of your knowledge and have gained a lot of information from the posted comments. We are in a 6 year old house and for the last 6 months or so, I have noticed fine sawdust on the items stored in the partly finished(concrete finished floor) storage room in the basement. The storage room is large and the sawdust is mostly on one side. My online research made me aware that it seems like powderpost beetle infestation. Also, couple times last year , I have seen some dark brown/black beetles on the carpet in the finished rooms in the basement as well as on the main and upper floor. Are they carpet beetles? I didn’t see them again this year. What should I do? Appreciate your suggestions.

    Hello Sumib,

    The best thing to do is to have an inspection done to your property so that you can identify the pest. You can also take samples to a local pest control technician and they may be able to help you identify the pest. Before any pesticides are applied to your home, we definitely suggest that you have the pest identified so that you do not misapply any pesticides. Until you can find out what the target pest is, we cannot suggest any insecticides for you.

    Hi Sunny!

    our hundred year old house in the Rocky Mtns. just north of montana is showing signs of powder beetle I think. For a couple of years now, fine powder has been dropping, lightly and consistently, in one area in the corner of my kitchen. Occasionally an exoskeleton of a larvae falls out too. The infestation is hidden behind trim, and the removal of the trim does not expose the problem, so we cannot access it. We might never treat this issue, as we are due to build a new home. My question to you is, how dangerous is the dust and perhaps, fecal residue, to my very young children? I do not keep or prepare food there, but is it dangerous to be eaten or breathed in?

    Thanks for sharing your knowledge! – Carmen

    Hi Carmen,

    Of course, anything that is foreign that enters the body can have adverse side effects, especially if your children has asthma or allergic reactions to dust and etc. However, I don’t think that there has been no proven research that the sawdust piles or feces of powderpost beetles have a direct link to disease. We recommend vacuuming daily. You should treat the home, but if you are building a new one, you want to make sure that you take all precaution and treat the new home before the wood is finished so that you can try and avoid problems like this in the future. We recommend Boracare or Timbor.
