How to Get Rid of American Cockroaches

Cockroaches are one of the most common pests that people will come across because of their extremely keen ability to adapt to any environment.  The five most common cockroaches that are found in the United States are German roaches, American roaches, Oriental roaches, Brown-banded roaches, and Smokey-brown roaches.

The American cockroach is the largest species of house infesting cockroaches. Unlike German cockroaches that nest inside the wall void areas, American cockroaches nest outdoors and only come inside to forge for food.  They are commonly found in damp and dark areas like in the basement, crawl space area, bathtubs, sewers and etc. However, even though cockroaches are found in the home, they are most commonly found in restaurants, grocery stores, cafes, or other places where food is prepared and stored. People will most likely run into American cockroaches after dark and in areas of storage. They can be flushed out or detected during the day when their hiding spaces are probed out.

Prevention
American cockroaches are transported into homes from boxes that were left out in infested areas.  They also move from one building to another, entering through small cracks in the building, around loose doors or windows, and through and along the pipe system.  Before bringing boxes home from areas that are infested, the box should be inspected thoroughly.  Also, sealing opening cracks and crevice areas in the building are preventative measures that people should take.  Sanitation is also crucial for cockroach control.  Cockroaches will enter buildings that have a good food supply.  Cleaning up after a spill of foods or liquids is extremely important.  Food should be kept in sealable bags and containers. Also, because cockroaches are attracted to moisture, removal of rotting leaves from the outside and limiting the moist areas that are in and around the premises can help reduce the areas that are attractive to American cockroaches.

Control Methods
Outdoor:
First and foremost, because American cockroaches come from the outside, treatment should take place outside as well as inside the home.  This can also be considered a preventative measure that people will take so that American cockroaches do not enter the home. Liquid insecticides (LambdaStar 9.7% CSFenvaStar EcoCap) are a surface treatment and crack & crevice treatment spray that can be sprayed around the perimeter of the building with a gallon sprayer .  The most thorough way to treat the home is to spray two feet up the building and spray the area up to two feet away from the building. Wet-able powder products (DEMON WP) are powder type products that must be mixed with water. They would be sprayed the same way as liquid insecticides.  The major differences between the two are that one is:

  • Liquid insecticides are liquid concentrates that have to be diluted with water whereas wet-able powders are in a powder form that is mixed with water and sprayed.
  • Liquid insecticides have a shorter residual time than wet-able powders.
  • Wet-able powders leave a more visible residue whereas liquids dry clear.

Both liquid insecticides and wet-able powder insecticides can be sprayed onto shrubs; however, they should not be sprayed on fruit and vegetable gardens. You also want to spray these insecticides around door frames and window frames, cracks and crevices around the structure, and around utility pipes that will lead to the inside of your home.

Granules (BIFEN GRANULESTALSTAR EZ GRANULAR) are products that for outdoor use only.  Granules have a similar residual time as liquid insecticides.  It is applied in 2-5 feet bands around the perimeter of the house.  Bait Granules (NIBAN GRANULAR BAITS) can also be applied in the same way as standard granules.  The difference in baits and regular granules is that baits are brought back to the nest and standard granules are a contact kill insecticide. Baits can also be used indoors whereas regular granule products cannot be used indoors.

Indoor: Indoor treatment is primarily for German cockroaches; however, treatment is also crucial for American cockroaches that enter the home for a food supply. Gel baits (  MAXFORCE FC MAGNUMADVION ROACH GEL) may probably be the most effective for indoor treatment.  Gel baits have a delay kill effect and after consumption, cockroaches will bring it back to their nest to share. Gel baits are placed by station in infested areas or squeezed out manually from syringes. Pea-sized amounts are placed 1-2 feet apart if they are squeezed out manually from a syringe. Granular bait insecticides (NIBAN FINE GRANULAR BAIT) can be used as well. These baits are typically used in crawl spaces, attics, and cellars with dirt or gravel floors. Granules can be applied liberally by scattering the granules under and behind the refrigerator, cooler, stove, sink, dishwasher, and etc. They can also be put into removable trays and place in areas like under the sink. Both gel baits and granular baits should not be put in areas that are accessible to children and pets. Aerosol sprays and liquid insecticides (ALPINE, LambdaStar 9.7% CSFenvaStar EcoCap) used as a surface treatment or a crack and crevice treatment. They can be sprayed around window sills and door frames.  Allow time for the liquid to dry before coming in contact with the treated areas.

    I don’t what i need. Maybe you can tell me. not had bugs in 50 years

    Hello!

    Well, for any general bug (pest) treatment, any liquid insecticide would work fine for you.
    The one that comes to mind is Talstar Pro. It targets over a range of 75 different pests.
    For general treatment, you would dilute 0.4 fl oz. of the Talstar Pro to 1 gallon of water.
    Talstar Pro has a residual time that can last up to 2-3 months.

    If you are treating outdoors for lawn treatment, I’ll recommend the Talstar EZ Granules.
    You would apply it evenly and we recommend that you spray it down a little bit with
    water after application so it can soak into the ground.
    This should take care of your pest problem!

    After reading your web-site, I now know that my house is invested with American cockroaches. My children are out of town for three weeks. What products would be suitable, given that I won’t have children poking their fingers in traps for just a short, 3-week period.

    Hi AJ,
    There are a variety of ways you can go about killing your roaches; it mainly depends on the size of the infestation. For a moderate to heavy infestation, I’d recommend a combination of a bait gel, liquid insecticide, and IGR. Both Maxforce and Dupont seems to be the most popular bait gels, though Maxforce comes in many different types because the roaches can become resistant to it. In terms of liquid insecticides, I would recommend Demon Max or Phantom because they both seem to be potent and effective. Gentrol IGR is probably the most effective IGR, and it is ESSENTIAL to make sure that you use an IGR so that the roaches cannot reproduce. Let me know if you have any other questions! :)

    I have a proplem with water bugs (roaches) in my horse barn. What can i use. P.

    Water bugs or American roaches will nest outdoors and go inside to forage for food. The best way to treat for them is to make sure you are doing outdoor treatment. You can create a barrier with a spray outside or you can use baits and attack the entire nest that way. Gel baits are the most effective indoors and granule baits or bait stations are the most effective outdoors. If you are opting to use bait stations, make sure you use select stations that are big enough to fit the water roaches. I know that the Maxforce Roach Stations with Hydramethylnon will fit them: http://www.pestmall.com/Maxforce-Roach-Bait-Stations-Hydramethylnon.html

    A manhole is in my drive and I continue to get American Roaches in and outside my home. The City says they do not travel thru water, etc. Yes, they can fly, swim and do anything. The City fogs the manhole frequently, but this still does not help for any length of time. If the lid on the manhole is sealed tighty, how are they escaping? I need help desperately and I see them everywhere…even in my dreams.

  8. 8

    Hello. The manhole may not be the only source that they are coming from. The manhole is actually just one opening to entire network underground and it is difficult to say where they are coming from. If you want to prevent them from coming inside your house, you will need to do a barrier treatment with an insecticide like Demon WP or Suspend SC. You may always want to consider using cockroach gel baits like Dupont Advion around the inside of your home.

    I have seen a few roaches in my kitchen over the past 2 weeks; however my son saw a group of them in my basement last night for the first time. My home is a rehabed home and is only four years old. We have new neighbors who we suspect the problem is from them. I have a 4 month old puppy. What treatments can I use that are guaranteed to work and are safe? I have nightmares about this problem and I cannot live with these things! Please help

  10. 10

    If they are the large American roaches, they will be coming inside from the outside. Making sure that you inspect the perimeter for any entry points (cracks and crevices near the ground, cracks and crevices around window and door frames, utility lines, etc.) and then sealing them is going to be the most crucial part of mechanical control. Then, you can use a concentrate spray to spray around the perimeter of the house. Also, target the window frames and door frames and all other potential entry points. If you would like, you can use baits. Maxforce roach bait stations with Hydramethylnon is a tamper free bait station that are prebaited and specially designed to fit even the larger roaches.
    If you have indoor German roaches that are smaller, you must use baits. Baits are going to be crucial for indoor roach control. Gel baits can be used on pipes under the sink, behind the toilet, on the edges that are underneath the cabinet, any other crack and crevice that cannot be reached by your puppy or small children. In open areas, you can use the bait stations (countertops, behind the fridge, on the floor in the corner in the bathrooms and kitchen, and etc).
    If you have any further questions, you can always give us a call at 1-800-788-4142, email us, or post again on our blog! Good Luck :)

    Hello! Unfortunately, I had to move back home – the home is infested of American roaches, now it’s a pretty big building. The apt, that I’m leaving at this moment is full and I out of my wits with them (I have bought the roach catchers, but no luck), I have a dog and am afraid what to use for my dog. The apt. next to me they had started renovations, but the apt was left half way (all walls down). My mother’s apt, is infested as well, but the worse there is my wee nephew home (a year and 3 months). She has cats (which I think it’s part of this problem too). I have cleaned (what I could), but they are all over the place, and it’s starting to creep me out I feel like I have them on my body now. PLSSSSSSSSS HELP!!!!!!!!!!!!!!!!

  12. 12

    Hi Ann, American roaches are large cockroaches that nest and breed outside and come inside for food. If you have an infestation of American roaches, you have to do outdoor control. This will require you to spray the potential areas that can be possible entry points for the cockroaches. Of course, this is difficult when you live in an apartment complex because you could possible be getting the infestation from your neighbors. You should contact your maintenance and see if they can help you with the roach control because entire exterior should be treated as well as the balcony doors and utility lines that enter the building. You can try to use baits. The Maxforce Roach Bait Stations with Hydramethylnon will fit both the small German Roaches and the large American Roaches. This is also safe around pets and children. They can be placed both indoors and outdoors. If you have any further questions or comments, please feel free to contact us again.

    How do I know what I need? Lived here for 7 years and never had a problem. We just got a new neighbor in the house next door. Just after they moved in approx 2 weeks I seen approx 4 roaches and a bunch of babies. I put down boic acid from home depot a week ago but seen a couple more tonight when I turned on the kitchen light. Can you tell me what to buy? I don’t know what kind they are. Thank you!

    Hello. My husband used a powdered outdoor insecticide around our trailer last week. Ever since, I’ve seen about 4 of these large (I think) American Cockroaches. We live on a couple acres in the woods, so we do tend to get spiders, which is the reason for the pesticide. Have these huge cockroaches come in the house trying to get away from the outdoor pesticide he put down? What in the world do I do to get rid of them?

  15. 15

    Hi Don,

    American roaches nest and breed outside and come inside to forage for food. They can enter through doors and windows that have been left open or other cracks and crevices in the structure, through cracks under doors, damaged screens, and etc. You should do outdoor treatment by spraying insecticide to create a barrier so that they cannot enter the premises. Barrier treatments require you to spray an insecticide in a barrier form. Bands will extend 4 ft up from the base of a structure and 4 ft out from the base of a structure around the entire perimeter. You should also spray window frames, door frames, in the garage, and utility pipes that enter the structure. Lambdastar 9.7 or Suspend SC are great products for outdoor barrier treatments.

  16. 16

    Hi,

    So I just moved into a new apartment about a week and a half ago. I noticed the first roach on just the second day I was in the new place. Since then my cat has caught and killed 4 large roaches which, I suspect from the picture, are American roaches. I’ve contacted the maintenance people for my building and they haven’t gotten back to me yet about this problem. I have tried to do all that I can to prevent them from coming in at night to scavenge for food, such as washing all dishes after use, keeping no food open, removing trash from the unit immediately before going to sleep and taking up my cat’s food and water bowl at night. I still keep getting woken up in the middle of the night to my cat hunting down roaches. What more can I do?! I have a phobia of roaches and this is driving me crazy! I need help! Thank you!

    I havr only seen 2 large looking cockroaches in my home of 1 1/2 years. Where should I start with preventatives? cockroaches disgust me and I dont want it to become an issue. They are light brownish red.

  18. 18

    Hi Andrea,

    The large looking cockroaches probably came from the outside. Outdoor control is necessary so that you can prevent them from entering the premises. Any liquid insecticide that has roaches on the label will work for cockroach control. We recommend Suspend SC. It must be diluted in a gallon of water and and sprayed onto surfaces. When spraying outside, spray around the entire perimeter of the structure to create a barrier. Barriers are made by spraying 3-4 feet up the structure from the base and 3-4 out on the ground from the base. You also want to make sure that you target areas like window frames, door frames, as well as utility lines that enter the building that can become potential entry points for roaches. If you have any further questions or comments, please feel free to contact us again.

  19. 19

    Hi Traci,
    Unfortunately, since American roaches come from outside and nest and breed outdoors, there’s no real way of permanently getting rid of them. You should spray around the perimeter of the house with a liquid insecticide. By creating this barrier, you are able to minimize the chances of the roaches getting indoors. The product we recommend is Suspend SC. If you have any other questions, just let me know! :D

  20. 20

    Hello Brittany,

    Unfortunately, unless you do outdoor control and keep all potential entry points closed, there is no real way to keep them out. They nest and breed outdoor, which is good, but outdoor control is necessary. If you have a large crack under the door and around windows and etc, they can serve as easy entry points for the roaches. We recommend that you continue to contact maintenance about the roach problem and have them inspect around your apartment so that they can check for cracks and crevices around windows and doors or even on the outside of the apartment as well. They should also apply a residual insecticide that has roaches on the product label so that you can create an insecticide barrier around the outside of the apartment. If you have any other questions, feel free to let us know! :)

    I have just moved down to louisiana and have noticed these ‘water bugs’ comin into my house… Now they dont get to me as much as the lil multi ones that you normally see but they still give me the shivers… My house is very old so therefore has alot of entry ppints that they could be comin in thruogh. Would plastic sheeting and that clear cocking be good enough to keep them out… With the help on the outside treatment that is….. I read that the only come indoors for food and that does help settle my nerves a little bit. But im from colorado and you only see roaches if your in a really nasty house if that…. Oh and im sure it does help that i live bout 10 min away from lake bistino and at the edge of the woods…. Please let me know if the plastic sheeting and clear cocking will be a good way to keep them out with the help of outdoor treatment help i hate bugs and get the hibbe jeebies and have to check my bathroom before me or my 3 yr old daughter goes in lol

  22. 22

    Hi Cyndel,
    You can use plastic sheeting and caulking but we advise that these are enforced with a liquid insecticide barrier. You are correct though, water bugs do come from the outside and the concept of control that you have in mind is exactly what we advise. This will help you keep the roaches out. We recommend Demon WP to be used on the outside. If you have a problem in the inside, we recommend that you use bait gels like Dupont Advion Roach Bait Gel. If you have any further questions or comments, please feel free to contact us again!

  23. 23

    Would you know of a plsce in minden louisiana that would sell some good high and mighty workin stuff cuz i woild just end up goin to the walmart and probably waste money. Also how often should i spray this stuff our house sits bout 2 feet off the ground should i throw some of those gel baits under there and spray as far under as i can

    Help, I want to cry! I just purchased an older home and tried to save some money by buying used appliances off of Craigslist. Unbeknownst to me the refrigerator was infested with cockroaches. It sat in my unattached garage first for about a week before it was moved inside. It was two days later that I realized it was full of cockroaches in the condenser. Now I have them not just in my house but all over the garage, outside, etc. As soon as I realized Tge issue I got rid of the appliances I bought, threw out all food I was unable to seal, sealed everything else, bleached and sanitized every surface I could, bought tons of Eliminator sticky traps at a local store, and bought Avert powder treatment from an exterminator and used it in areas my two year old and dog can’t access. I wash all dishes immediately now, keep the dog dishes clean and dry when not in use, throw out all garbage other than paper outside. I’ve caught a few in the sticky traps, and killed a few myself but haven’t spotted any inside recently. I’m seeing everywhere outside now though. Even had one in my mailbox today! This all started two weeks ago. I’m constantly patrolling for them, stressed over every crumb my toddler drops, dreaming about them. Help! What else can I do?

  25. 25

    Hi Angie,
    It sounds like you are doing everything right so far. I advise that you keep using the Avert Dry Flowable inside. Make sure to target areas like behind the stove, under and behind the refrigerator. You may want to keep the Avert application limited to those areas and use Dupont Advion Roach Bait Gel in areas like under the sink in the kitchen and bathrooms, behind the toilet, in the laundry room, underneath cabinets, and etc. Gel baits too, should not be applied except for in areas that your child and dog can access. Outdoors, we recommend applying a residual insecticide with an IGR. A residual insecticide can be something like Demon WP or Suspend SC. Demon WP is limited to outdoor use because of a visible residue that it will leave behind. Suspend SC will dry on clear though. The effectiveness of both is very similar though and will kill the roaches when they walk across treated surfaces. They must be mixed with water before application. Usually, insecticides are mixed in a gallon of water. In the same gallon of water, use Gentrol IGR to mix in as well. IGR does not have a killing effect but it will control their reproduction.

    When applying the insecticide, spray around the entire perimeter of the house. You should spray on the outside walls in a barrier form that is 4 ft up from the base and 4 ft out from the base of the structure. Spray window frames and door frames. You can also spray around the mailbox and on the outside of the mail box as well. Spray in the baseboard areas inside the garage.

    All treated areas should be left alone to dry before you come in contact with that treated area again. Always read the label before application. If you have any questions on the products or roach control, feel free to contact us again!

    I live on the top floor of a large building downtown. Last week a water pipe broke in a unit causing much water damage, mostly to one unit and those below it. I just had some water on the floor near the door. Cleaning crews have been in, with big fans all over the dry up moisture that could still be in the walls or baseboard. Last night I walked into the bathroom and found a large cockroach -american I think. I was able to swat it with a broom and dispose of it but still freaked out by it. Could it have here long, just flushed out with all the activity with the broken pipe? Or could the cleaners have just brought it in (unknowingly) with all the equipment? I just want them gone. I don’t want to trap or bait them, don’t want to have to clean up a bunch of dead roaches, I just want to get them out and keep them away. Saw something about a barrier product, is that something that would help, or would the gel bait be better?

  27. 27

    Hi Me,
    Usually, large, American roaches are occasional invaders and do not normally nest indoors. All the activity with the water leaking and the maintenance may have triggered them to come out of a temporary hiding spot. There’s a lot of possibilities as to how it got there but I do not think they pose as a large threat. You can treat the outside or the baseboards with a spray called Suspend SC, but I do not think a baiting is necessary. If you have a balcony or veranda, it will be good to treat that outside area with Suspend SC. You should also treat the outside of the front door because those two doors will be the two main entrances to your apartment.

  28. 28

    Hi, We had our roof redone and since then I have noticed LARGE American Roaches in my house and attached Garage, but for years have struggled with “waterbugs” outside and in my garage that eventually make it inside my house.. What products do you recommend?..

  29. 29

    Hi Julie,
    It is important that you do a regular maintenance on the outside of the structure so that you can keep the waterbugs from coming in. We recommend a product like Suspend SC to apply around the entire perimeter of the house including window frames and door frames as well as in and around your garage. If you have any questions, please don’t hesitate to call us again.

    Moved into a house that I am renting. I started seeing American cockroaches right away, a few here and there. The guy came to spray twice in a 6 month period, but now I am infested. They are coming out of my daughters tub! I’m thinking the whole house needs to be fumigated! The exterminator is coming on Thursday, but they are EVERYWHERE….closets, kitchen, bathroom, bedrooms, and I see one at a time. How long will it take to get rid of them and what should I tell the exterminator?

  31. 31

    Hi Jenn,
    Are you sure they are American cockroaches? It doesn’t sound like an American cockroach infestation and instead, it sounds more like a German cockroach infestation. If you have an infestation of roaches indoors, we recommend using baits like bait gels and bait stations. Dupont Advion Roach Bait Gel is a very effective and popular roach bait gel to use. Bait gel can be applied in areas like under the sinks, behind the toilets, under cabinets, laundry machine lines, under and behind appliances like microwaves, refrigerators, and stoves, and etc. If you have any further questions or comments, please feel free to contact us again.

  32. 32

    Do they come in when weather is bad. Cause i only see them when it is going to rain.

  33. 33

    Hi Michelle,
    Just like people look for shelter when the weather is bad, pests like rodents and cockroaches will look for shelter. They may enter homes or find natural shelter. Because American cockroaches are normally an outdoor pest and are really only considered occasional invaders, it is not much to worry about. You may want to do some outdoor general pest control on a regular basis and spray around the entire perimeter of the house, targeting key areas like the door frames, window frames, and the base of the structure. Demon WP or Suspend SC are good general pest control products to use on the outside of a building. If you have any further questions or comments, please feel free to contact us again.

    Hi,
    I moved into a new apartment four weeks bacK. I found an American cockroach within 10 days of moving and promptly killed it. I couldn’t figure out if it was in the apartment or did my furniture pick it up during the move. I found another one today about 4 weeks after moving in. I have Roach baits in the kitchen and bathroom. I used combat and hot shot bait. i have a walk in closet that houses my water heater so the plumbing runs into the room. I have tried taping it up but there are still small crevices that I cannot effectively reach. Should I call an exterminator or use traps first ?

  35. 35

    Hi Shelly,

    We recommend both. Keep the traps out until you are able to contact the maintenance of your apartment complex and it should be a part of your contract to receive pest control. If you have any further questions or comments, please feel free to contact us again.

    Hi,
    We moved into our house in Florida 4 yes ago towards the end of summer. It is a concrete block ranch home built in the late 60s. We saw a few here and there towards the end of summer but little to none during winter. But once spring came around we found out we were infested. We couldn’t understand since we keep our home immaculate. We have done everything you can think of including; professionally fogging attic, replacing insulation with borate treated blown, new ducts, sealed all doors/windows/baseboards, professionally treat inside/outside of home regularly (4 different companies), treat with DIY products mentioned here, sealed with foam behind all switch plates, had back flow valve put on sewer line, replaced plumbing all to no avail. Spring is here and so are the american roaches. Even in the daytime and in places where there are no food sources or water like the bedrooms. My question is do you think they are living in the walls, especially exterior, and can they be killed there? We cut open the wall behind kitchen sink and while there was no leak there was signs of roaches within the plastic batted insulation. As mentioned somehow they come back every spring and last till first cold.

  37. 37

    Hi Matt,
    It is not normal for the roaches to stay and nest indoors and are considered outdoor pests. Have you treated the exterior part of your home? This means a full perimeter treatment around your house with a residual concentrate spray targeting the entire base of the home around the whole house and window and door frames. We recommend Cy-Kick or Suspend SC.

  38. 38

    Hi Sunny,
    Thanks for your response. Our current pest company puts down Adivon grandular bait, Entice, Extinguish and Termidor as well as spot treat interior doors as needed. Is this typical and do we need to ask them to do more? I don’t see the chemicals you recommend on their list. Their full lists of products they could use are Catalyst, CB 80-CB80, Conquer, Conserve, Dekko packs, Demon WP,Invader, Temprid SC, Transport Mikron, and Sevin. Each has a different use but some are probably comparable to those you recommended, right? Need to determine if what they have could help prevent or if we really need to do ourselves which is hard to consider since we are already paying.

  39. 39

    Can termidor be used to kill roches

  40. 40

    Hi neal,

    The active ingredient in Termidor will kill roaches, but Termidor can only be used as an outdoor surface treatment and is not labeled for indoor treatment. If you have any further questions or comments, please feel free to contact us again.

    There is a OLD septic tank next to my apartment which I know houses American roaches. I complained to the city that this tank was not sealed properly and since it has been resealed, I have American roaches coming in from the bath tub pipes. I have never seen one in any other part of the house. Is there something I can put down the drain?

  42. 42

    Hi Stela, Sorry to hear about your unfortunate problem. Unfortunately there is not an insecticide you can use to pour down the drain… However you can spray the insecticide around those areas. Good news is that American roaches do not nest inside the wall void areas so the ones you are seeing are just going to be occasional invaders.

  43. 43

    I want to cry, I hv to sleep with the lights on
    I live in Tennessee, and we occasionally saw American roaches now we see them every day, my husband just found one in our bed
    We use professional extermination every 3 momths, and we spray with a spray from lowes as well
    But they won’t go away
    In the bed, we can’t sleep
    HELP

  44. 44

    Hi Latrecia,
    I’m sorry to hear about the roach problem you are dealing with. American roaches usually nest outdoors and occasionally forage indoors in search for food. I would recommend using a product like Suspend SC to spray around the outside of your home. If you get lots of rain in your area Suspend Polyzone may be a better option. You can also spray this product indoors along the baseboard areas, cracks, and crevices.

  45. 45

    I have purposefully observed at 3 different times an American cockroach that has been turned on its back due to Demon WP. If the roach is left for several days it starts to move ever so slightly, then it will be gone. Now, I have not done this in a controlled way so there are possibilities such as a spider carting it off… Etc, However, I have noticed the inanimate go to animated… Anyway, my point and question is not to say that the roaches can survive demon after time, it is to ask if anyone has noticed this as well? It would not be a common observation. I have noticed this in the large adults, not the nymphs or other roaches. I am in pest control so I have watched for this situation around my workshop when I have the opportunity. Anyway, just thought I would see if anyone has anything to say… Thanks!

  46. 46

    Cockroaches are carnivorous creatures so its possible that another cockroach may have taken the dead body of the roaches…
