    5 of 5 Stars   Outstanding Results from initial treatment
    By Kyle on 09/30/2013

    After having issues with black widows and many other spiders this summer around the outside of the house and in a few inside locations, we decided to do a treatment with DemonWP. This was done 2 weeks ago and the results have been outstanding. Just days after the treatment the number of dead bugs and spiders found on the ground and around the foundation of the house was amazing to see. Also validated that one Black-Widow as killed (left one that we had found as a test case before we sprayed). Thanks DoMyOwnPestControl. Outstanding product at a reasonable cost.

    5 of 5 Stars   Demon WP
    By Cindi on 09/30/2013

    This stuff works great! You will have to apply it more than once at the recommended strength. One pouch will spray most homes twice. I will be spraying a third and fourth time, and then monthly, to make sure we get any stragglers, but it works really well. It has worked much better than the professionals we hired, who seemed to only feed our bug problem. I don't know what they used, but this is 100 times better! It's also about a 90% savings to do it ourselves!! Win/win!

    4 of 5 Stars   demon: sending bugs to "you know where"
    By Wayne on 09/07/2013

    Demon is the best roach poison i have ever used. it continues to kill roaches for up to one year after spraying an area. I have a problem with spiders, as i live near a lake, and so far, the jury is still out concerning the effectiveness of demon on spiders. time will tell.

    5 of 5 Stars   Demon WP vs german roaches
    By Glenna on 03/22/2013

    Demon WP is a wonderful product. I was very happy with the results after spraying for german roaches. A week after spraying they are greatly reduced in numbers and I am confident after a few more sprayings they will be gone. It does not make the house smell either. Hope to never have to buy it again but if I ever have another pest problem I would definatly get this one!

    5 of 5 Stars   Nail box elder bugs
    By Gb on 03/22/2013

    Our front yard was inundated with a massive influx of box elder bugs, not that big a deal except that I learned they suck the fluid out of every blade of grass and other vegetation. So my trusty Demon was brought into the fight and it nailed them. An excellent product for a wide variety of problems. I perimeter the house monthly with the stuff, and there are no bugs in the house anywhere. A good product. I highly recommend!

    5 of 5 Stars   First time user on the Outer Banks of NC
    By on 08/20/2013

    As a former farmer for many years, I am accustomed to working around chemicals and had no problem mixing and using the Demon WP I purchased in a one-pound container. It mixed easily. I was primarily spraying for cockroaches, and it did the trick. Before I finished spraying aound the house, I was seeing dead and dying cockroaches on the ground. We also had a centipede issue inside our beach house, and that was also eliminated. The chemical worked for the insects we were targeting and I plan to use it again. Unless I am mistaken, I mixed around 8-10 one gallon sprayer loads at the higher recommend rate for my 3K sf home, and there was enough material for another treatment remaining. My purchasing experience was also good, and the product arrived sooner than I was expecting using normal shipping. I don't normally provide feedback such as this, but this was a much better than usual experience of purchasing a product online.

    I have used the Demon WP around our home and it has stopped all the bugs in their track. Excellent product. My son in Florida told me about it and I have been using it ever since. If I need other products I certainly know where to go. Thanks again, Don Kaser

    By Reta on 12/01/2014

    Roach free for almost three years now. Keep on hand to control spiders and other insects in the home. Just spray once every six months. Also great for keeping wasp, yellow jackets and other bees from making a nest around the outside.

    5 of 5 Stars   Demon WP Works
    By Jr on 06/20/2012
    Verified Purchase

    I have bought other products at the local Wal-mart and for the most part they work somewhat. I decided to try Demon WP. We live in El Paso and we have a lot of landscaping rocks around our house. Plus what grass we have is watered 3 times a week. The rock and wet grass attracts tons of those nasty cockroaches. They also end up in your house. I got the Demon WP in mail yesterday plus I ordered the 1 gallon sprayer. I mixed it all up and sprayed all around the outside of my house plus in the rock areas. I woke up this morning and found tons of dead cockroaches on our back patio and yard. Needless to say they never made it inside. I have yet to spray inside but I will. I will never buy any pest products from Wal-mart, K-Mart and etc again. I plan to spray monthly. 4 packs for $10 which makes at least 4 gallons of spray is great compared to the $20 I spent recently getting a 1/2 gallon of some stuff at Wal-mart which worked but not as good.

    1 of 5 Stars   Demon doesn't work
    By Mari on 08/16/2014
    Verified Purchase

    I have now used 2 packets of this product and it flat out doesn't kill a thing. I've mixed it properly in a gallon jug. I just sprayed one ant tonight & it got up, kept going, I sprayed it again and it got up again & kept going. Third time and it still didn't kill this single ant. I would not recommend this product. I'm completely unhappy with it.

    We are sorry that you are unhappy with the Demon WP. Please be advised that because Demon WP is a residual insecticide, it is not intended to be used as an instant knockdown for listed pests. The active ingredient will still take time to affect pests sprayed with it. If you have further questions about the use of Demon WP, please feel free to call us at 866-581-7378 M-F 9a-5p EST.

    1 of 5 Stars   A "NO-GO"!!
    By Barb on 08/14/2012
    Verified Purchase

    I sat on this website and read all 300+ reviews. I was truly convinced that this product worked. Anything with the name Demon on it suppose to kill everything. This product didn't even kill the local ants. As a matter of fact, my bug problem (spiders, roaches, ants) actually got worse. i need some help. i need to get rid of these insects before they get bold and crawl in my families ears'. So what product REALLY works.

    I was having a problem with centipedes in my house and they seemed to love my bedroom which freaked me out. Nothing else has worked for those critters but after spraying demon wp I haven't seen a single centipede or anything else.

    5 of 5 Stars   Demon experience
    By Jim on 04/09/2014

    Used the Demon in front of my garage and doors. Next day dead bugs that never got beyond the Demon. Very fine powder so be careful when you open the container because it will start to float out. Where a mask or just be careful and slowly open it.

    5 of 5 Stars   Great stuff for Wolf Spiders
    By Gman on 03/15/2014
    Verified Purchase

    I dislike anything with eight legs and unfortunately the spiders and scorpions are hard to kill. Demon WP works better than anything else I have tried. You have to use the stronger concentration for spiders and it does not work instantly but in a day or two you will start seeing results. Glad to have Demon around.

    Packets inside envelop are a pain to open. Amount to water ratio is very vague. Stuff kills carpenter bees and powder post beetles asap. Use a dust mask when mixing.

    5 of 5 Stars   GOT THEM CRITTERS ON THE RUN
    By Al on 11/25/2013
    Verified Purchase

    A friend turned me on to Demon wp insecticide, she was purchasing it at store near her. I used it for a huge cluster of spiders all over her front porch. After one application we saw no more spiders. We then decided to take the war indoors, where large palmetto bugs, and other bugs had rooted into her home. After applying Demon wp there in double concentration each morning we woke up to find only dead bugs in every area of the house. I was sold, am now using in my home.

    5 of 5 Stars   An Unbiased Experiential Review
    By Anthony on 04/08/2013
    Verified Purchase

    Hi All, Demon WP Insecticide delivered on it's claims - killing insects, bugs, and most importantly (and the reason why I purchased this product) brown widow spiders while not having a chemical smell and not harming my paint, bricks, flowers, trees, and shrubs. I live in Southern California and residents used to have to contend with black widows, but over the last few years, the brown widow spider has migrated here and taken over and I have a child at home that I do not want bitten when playing with toys or in the garage.  I have used bug spray for the local do-it-yourself hardware stores but in my experience the poison works well on crickets, ants, and perhaps a rogue spider but not on the brown widows. I read the reviews and ordered from DoMyOwnPestControl and the service was great. I placed an order and had the product a few days later. No hassle, no worries, and I would not hesitate to order again. I read the instructions, filled my hudson sprayer, and went around the house and sprayed. I did watch the video and I appreciate the tips that were given. Like another reviewer stated the bugs do not instantly run out and shriek while withering away to dust. But, the next day I was happy to see the carnage of my previous day's activity. Crickets, moths, and brown widows dead. I had brown widows dead by my barbecue, my clay pots, hanging dead on my trashcans, some in the plants in my flowerbed, and even on my gate. They were everywhere, but they were dead. I also sprayed this on my ornamental plants and trees and it did not harm the foliage at all. I give this product 5 stars for killing the bugs and spiders but I cannot speak into the longevity of the product because I have only used it once in the last month.

    I live in a country house among spiders and all other creatures which will crawl inside the house all the time. It is the second week that I have sprayed Demon WP Insecticide and I have not seen a single live bug in the house.

    By David on 01/25/2010

    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.
