Customer Reviews for Demon WP Insecticide

I used Demon WP last year to control asian beetles (lady bugs.) It kills them on contact, and kills them for the remainder of the fall season. By spraying it outside the first day I saw the beetles come to the house, I was able to keep most all of them from entering and wintering in the house. This year I am going to order a pound tub and spray the out buildings as well as the house.

I have used Demon WP and I know it works . If you have a roach problem in your home this will kill them and will keep killing for months . It goes on wet and dries to a powder . You will be seeing dead roaches in 24 hours and 1 application will last months of killing power . It is safe too, I have pets and a small child and have never smelled or had a problem like pest control services cause . Try it and you will be satisfied.

The Demon WP Insecticide performed better than any other product that had been recommended to eradicate millipedes. Very satisfied.

I received this product as a gift from my sister and have been using it for several months. There is no doubt that Demon WP is by far the best product I have ever used for killing any/all inside/outside/ household pests.

We have used Demon WP Insecticide before in another state. It was very effective in killing spiders, water bugs, roaches, etc.

I've used Demon WP to rid scorpions and spiders from my home, barns, & boat house. After spraying, 2 weeks later I'm finding dead insects everywhere, Thanks for a great product.

I finally have found a product that eliminates pesky cockroaches. I thought that having stray cockroaches was a rite of summer. A friend told me about Demon WP. After 1 application the stray roaches were gone. I treat my home 2 times a year and now I am roach free. This is the best product I have found for pesky cockroaches.

I am completely satisfied with this product. I've had ant problems for two years and after applying Demon WP the ants are all gone. I have not seen one ant or roach in months. First, I had to hire a professional who could not get rid of the problem so I decided to take matters into my own hands and glad I did. I saved a ton of money.

Awesome product. I've used it for over 10 years in my office and now in my home on 5 acres. It, along with a once over my immediate yard with insect granules in the spring, limits the outside cockroach problem to only a few stragglers a year due to open doors and/or windows. I spray the base boards and the perimeter of the house each year and we're covered. In this part of Texas where its hot and humid, Demon WP is a tremendous relief. Thanks!

Amazing product. I had a problem with crickets in my garage. The day before I used Demon WP, I tried the Ortho Home Defense spray that you can get at any home improvement store. Ortho worked to kill crickets if I sprayed directly on them. I killed all the crickets I saw, but a couple of hours later there were a ton more, even though I had sprayed all the cracks and crevices. Well, the next day, I received Demon WP along with the plastic Chapin sprayer. Usually there are at least 20 crickets all over the walls of my garage. This morning, I went into my garage and checked again. This time there were a bunch of crickets on the garage floor...but they were all dead. Demon WP definitely works!

I had just put on Demon WP inside and outside my house to control earwigs and roaches, a day later I saw a few dead roaches in my garage and a few outside along with a Black Widow! I didn't even know I had those. I feel a bit safer knowing that my 2 year old, 3 month old, and small dog should be safe. Well, I don't know about my 2 year old. He's in everything ;) The local pest control service wanted 50 dollars a month to get rid of bugs or 150 for a one time application. For 15 dollars and 4 treatments that probably will work better anyway. Forget the exterminator :)

I sprayed this Demon insecticide in closets, under cabinets, appliances and outside of the house. I see a lot of dead bugs now and no live ones. It even killed a few spiders and other bugs outside the house. It is easy to use with a pump sprayer . I would highly recommend it to everyone . Thanks and I will buy again .

I have 2 large dogs in my house. Had fleas really bad. I tried every type of bug bomb- Home Depot, Lowes, and Walmart had and it seemed like they multiplied. My parents turned me on to this product Demon WP. I sprayed my baseboards, windows, doors, weep holes in the brick, the entire perimeter of the house, the soffit on the house, and the perimeter of my yard. After all that, I still had 2 pouches left, so I went ahead and sprayed my lawn. I have not seen another live bug in the house for 2 years. I may not have applied it the way I'm supposed to, but this stuff is awesome. Highly recommended.

Perfect. I have the worst ant problem in a 4 bedroom house. I tried everything at Walmart and decided to Google "pest control". Google gave me this site and I have not seen one ant in the two months I've had the product. Demon WP insecticide is amazing.

I have been using Demon WP since 2001 and it's the best I have found for inside and outside applications. I don't even consider anything else.

I have found that Demon WP is the only product that will kill carpenter bees when they start to bore.

Great product!!  I've been using this product for 2 years and living by the ocean, we have our fair share of palmetto bugs, roaches and every crawly bug known to man. Demon WP keeps the house insect-free and considering I have a bug phobia, this means a great deal knowing that there aren't any unwelcome pests crawling around our home. Anyone having a problem with bugs should try this product...you'll be glad you did!!

"It just works" says it all. I have been using Demon WP Insecticide for 10 years. Forget what you read about multiple applications per year. Maybe outside, but inside, unless you wash or vacuum it away, it lasts forever. I haven't used it in 2 years indoors and it's still killing. I thought, after two years, though, another application couldn't hurt. The first time you use it, when you wake up the next morning, you will be in awe of the dead insects in your house. Just do every base board, even in cabinets and closets and every threshold into your house, garage, carport, etc...threshold exteriors need to be repeated if exposed to the elements. This stuff is the last word in pest control. Don't waste your money on supermarket and building supply store junk and pest control companies that come out and use this same stuff, and bill you $250.

We have been using Demon WP for about 30 years. We hit a slump with kids and business draining us and couldn't afford the luxury of Demon and used some less expensive products. Yuck! They would work a little bit, wear out soon with a residual of about 6 weeks. With our kids grown and gone now, we have decided to go back to Demon. The real residual effect is more like 6 months and the day after we spray we find roaches sleeping the eternal sleep all over the house. Upside down, if you know what I mean. It's a wonderful product and I recommend it to anyone who asks.

Excellent product. I have been using Demon WP Insecticide for MANY years mostly for exterior barrier treatment and in and around garages. I was very impressed. I will never forget the first time I used this product. I sprayed a heavy line in front of our 3 car garage which was getting bombarded by all kinds of crawling insects. It created about a 10-12" line on a hot & sunny day and it dried very quickly. I did it a second time thinking it evaporated, again it dried within a few mins. Came home from work the next day and a solid line of dead bugs exactly where I sprayed. Was as if it was an invisible electric fence. At this point I was sold on this and nothing else. I have continued to use it for years without fail. I found it lasts quite a while but depends on how much direct rain the treated surface area gets. Recommend 100%

My daughter wouldn't come out to our new ranch because of the spiders and scorpions. One application of Demon WP Insecticide got rid of every last one around the house and barn! Like someone else here said, we find a row of dead bugs, spiders, scorpions, even flying insects like wasps when we arrive every weekend. They are all lined up along the "spray line". It is an invisible fence! Now my daughter will come out because she is convinced she is "safe" in the house etc. I highly recommend this product.

I bought Demon WP and used it on our infested garage. Within a few minutes there were several dead and dying bees on the floor. We had wood borer bees all over the place. Every place I sprayed has been free of insects for a year now. I am going to order more and spray everything around the house to keep these bees under control. I would highly recommend this product.

Have received this and used it. Works great! Plan to order more. Any bugs I have seen are on their back and not well if not already dead.

I live on a farm and every Spring we have thousands and thousands of lady bugs. They land on my windows and screens by the handful. This year, on your advice, I purchased Demon WP Insecticide and sprayed it around the base of the house and on the outside window sills. The very next day 90% of the ladybugs lay dead on the ground. Within days I noticed that not only had the lady bugs disappeared downstairs, but also in my basement, second floor and attic.
