Review by Kb (Posted on Thursday 12 January, 2012)Years ago at my old home, I had a roach problem after first moving in. I used foggers and gels, finally bought some Demon sprayed around outside real good, sprayed in the attic, and all around inside the house. After spraying, the only bugs I found were dead and never had any more live roach encounters. I bought some more for my new home, sprayed the perimeter and around plumbing fixtures. So far so good, this stuff is the best!
Review by Tim L. (Posted on Wednesday 04 January, 2012)This cypermethrin stink bugs is the best. I will purchase this again. Thank you so much

Review by John Lakers (Posted on Thursday 04 August, 2011)Demon WP Insecticide is really good, I used this few weeks ago, and like they said in the information, it is very long lasting product. It’s amazing to see a cheap product that is very effective and long lasting.
Review by Candace A. Sweeney (Posted on Thursday 04 August, 2011)Demon Wp is certainly effective against ants. I had tried other expensive products, but this was the best. Will definitely buy from the seller again.
Review by Judy Bradshaw (Posted on Wednesday 27 April, 2011)The Demon wp envelopes work great for roaches! It has not failed me yet! haha
Review by Monica Nash (Posted on Wednesday 27 April, 2011)I did not like how the wettable powder was left visible on the surface, but i can’t complain because it got rid of my roach problem. Can anyone suggest something that works as great as the demon wp but dries invisible??
Review by Allison Hodge (Posted on Monday 25 April, 2011)I highly recommend this product.
Review by Huijun K (Posted on Wednesday 02 February, 2011)This Demon Wp works very well! We had fire ants invading our home. After applying this product inside and outside of our house, we found tons of fire ant bodies... No more ants!
Review by Abbigail Garcia (Posted on Monday 13 December, 2010)I think that the problem why my results were slower than the other people who had the same infestations were because I used DEMON WP Insecticide after 20 hours after I mixed the solution with water. The next day, I used the left over I had and then I started seeing MAJOR improvements. Overall, the Demon WP was a good product if you use it right after you mix the solution into water!
Review by Regina Richardson (Posted on Friday 19 November, 2010)great product that lasts for a long time. This company also ships pretty fast so great experience overall with my purchase.

Review by Stanley Ryan (Posted on Saturday 04 September, 2010)i love how the demon wp envelopes come conveniently packaged with 4 packets that you can easily mix with 1 gallon of water. For a regular non professional user like myself it was just too easy. i loved it!! i’m already stressed enough with these darn spiders around my house... I don’t need more stress with trying to figure out the correct way to mix the darn thing.
Review by Ted Hobbs (Posted on Wednesday 04 August, 2010)Because the demon wp envelopes come in small packs, I don’t have to worry about safely storing them for the next year... which is the reason why I always go with the demon wp envelopes. They should really try coming out with other pesticides too in small quantities. Great marketing strategy for people like me who do not like to store pesticide inside their homes.
Rated by Alvin Meadows (Posted on Sunday 02 May, 2010) Review by Annie C. (Posted on Tuesday 20 April, 2010)I had a roach problem at my business. I own a restaurant and the last thing I want is my customers see a roach inside my restaurant. I purchased demon wp with gentrol IGR. It worked great and killed all the roaches. The demon wp comes with 4 pouches inside so you can use it up to 4 times. I saved a lot of money and will purchase more in the future!
Review by Bm (Posted on Monday 01 February, 2010)Tried DEMON WP and immediately it started to work. My mom keeps her house very clean but was still having roach problems,she had professionals come spray and it would not solve the problem.I sprayed outside first next the inside and roaches immediately started coming out and dying. Within 2days her home was finally roach free.
Review by Gail E. (Posted on Friday 22 January, 2010)Got exactly what we ordered. Arrived in the mail very quickly. Totally satisfied. Thank you!!

Review by C. Slover (Posted on Tuesday 04 August, 2009)I had been having a lot of problems with stink bugs and have been looking for products to use for treatments, but like most people the amount they offered had made me very hesitate. I wanted to try the product to make sure it worked before purchasing a big qty. Then I came across Demon WP which came in envelopes so I tried and worked great it took care of the outside control for me... now just have to find one that works for inside of my home.
Review by Fanny Lee (Posted on Friday 24 July, 2009)The DEMON WP Insecticide is a great product! I'll tell you, with the use of this DEMON WP Insecticide, the ants will DIE completely! I can finally stop worrying and I can sleep in peace! It's odorless and stainless so the only clean up to do after the execution of the ants is cleaning up the ants!
Review by Josh W. (Posted on Thursday 28 May, 2009)DEMON WP works really well! The fire ants in my home were gone after two days of usage! I sprayed it with the Chapin 1 gallon sprayer that my wife had purchased beforehand. It doesn't stink up the house either so it's okay to spray with your family in the house! Just let the DEMON WP do all the work!

Q. Demon WP Insecticide for roach control
Hello, I bought some of this product from you a few weeks ago, and I have used it twice, and it has killed alot of roaches, but each time I spray, it seems to bring out more and more roaches(mostly little roaches), is that normal? And how often should I spray, or do you recommend something stronger? Thank you,
A.
Well, Demon WP Insecticide is not an attractant or a lure so it will not actually lure them out.
However, normally, you will see higher activity when they are disturbed. Since Demon WP has a delay kill effect, it may be that infected roaches that have come in contact with the poison are making it back in time and disturbing the nest in some way. Also, normally, roaches will not come out when there is light. That is typically why they will scatter when the light is turned on.
However, if they were to come in contact with this pesticide or any pesticide of its like, it interrupts their internal nervous system and they cannot differentiate such things as normal routines and etc. This may also be why you are seeing more of them than usual.
Treating for roaches will really depend on the type of species that you have infesting your home. Also, indoor and outdoor control will vary a little bit and some methods will be more effective than the other depending on location and species of the roaches.
However, we would like to assure you that Demon WP is by far one of the most powerful pesticides available for a broad spectrum of crawling insects.
It would not be normal if it didn't kill any pests at all. But if you are interested in other methods of kill, please feel free to contact us again.

Q. demon bug spray for fire ant
How much of Demon WP should I apply to fire ant mounds?
A.
For individual fire ant mounds, apply Demon WP as a drench treatment. Gently apply a total of one gallon of solution over the surface of mounds up to 12 inches in diameter.
It is advisable to use 2 gallons for larger mounds. Thoroughly wet mound and surrounding area. Treat new mounds as they appear.
Pressurized sprays may disturb the ants and cause migration. If possible, applications should be made on warm days after recent rainfall.
All colonies in the vicinity should be treated, including those that have not yet constructed a mound.

Q. Demon WP Cypermethrin Products
Hello, thank you for answering my question so quickly. I just have one more question. After I mix the Insecticide, how long and I keep it stored, before it loses it strength (in case I have some left over after I spray)? Thank you,
A. Thank you for contacting us. Once it is diluted or mixed, it cannot be stored for more than 24 hours or it will lost its effectiveness. In the powder form though, Demon WP has an indefinite shelf life if it is kept in a cool, dry place. If you have any further questions or comments, please feel free to contact us again.

Q. demon pest control
When is the best time to treat cluster flies with Demon WP?
A.
We recommend making exterior treatments in late summer or early fall before flies are observed alighting on surfaces and then apply thoroughly on siding, under eaves, and around windows and doors, paying particular attention to south-facing surfaces.
It is advisable to apply just enough dilution to adequately cover the area without excessive dripping or runoff. Heavy precipitation prior to frost may require re-treatments to maintain protection.

Q. Demon WP Insecticide for cockroach control
Thank you very much for your reply. You have been very helpful. Just a couple more questions, if you don't mind. I have only been spraying a few times, in the past few weeks. Do you think I should give it more time to work? And how often should I spray? And can you suggest anything to use along with the spray? Thank you
A.
Thank you for the reply.
Demon WP actually has a residual time of 2-3 months and it is only necessary to continue to spray more than that if the infestation is very heavy, but you should not spray more than once every 8-10 days.
Also, additional material will really depend on the species of roaches that you have, but we always recommend a bait type of poison for roach control.
Dupont Advion Roach bait gel, Alpine roach bait gel are just a few of the ones that we recommend for roach control. Baits are especially effective for indoor roach control

Little did I know about insecticides. So when I found pest infestation in my home, I immediately resort to buying any kind of insecticide. This proved me wrong because they were not effective. I then researched and I came across Pestmall’s Suspend sc Insecticide. The label says so much about the product so I bought it and applied it to the infested area. To my amazement, there was a quick result. Great product! Thank you Pest mall!
