    5 of 5 Stars   Demon WP Absolute Bug Destruction
    By Tim on 05/02/2012
    Verified Purchase

    I Sprayed this on the outside foundation of the house, door frames, window frames, kitchen and bathroom cabinet bases, etc. Demon WP, Gentrol and Maxforce FC Magnum bait totally decimated a 20 year fight with German roaches that I've tried to kill with everything locally available. It's been about two weeks and I'm still Amazed..thank you for an amazing product, good prices and fast shipping.

    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   The Right Stuff
    By Cary on 10/01/2011
    Verified Purchase

    Folks, if you want to kill them this is your stuff! Once applied it kills for a year! When cockroaches touch this poison they only crawl about 2 inches and die right there! A drop dead killer!

    5 of 5 Stars   There is hope!
    By Theresa on 10/07/2012

    We were literally overrun by roaches. They came in on a used refridgerator that we bought. We tried everything we could find but nothing worked. I was about to call in the professionals last spring when I found this product and decided to give it one more shot. WOW! The population was reduced to nearly nothing. I'm starting to see just a few that must have survived the first go-round and reproduced so we're ordering more. We'll continue to apply just as a precaution even after they're gone. Thank you so much! I have hope.

    1 of 5 Stars   Poor Product
    By P. on 03/22/2012
    Verified Purchase

    I tried the Demon WP Insecticide on an Earwig that I caught inside my bathroom. I used two packs of the Demon WP 4 pack mixed in 1 gal sprayer of water. The product did not kill or slow the bug down and it was in a cup at first and then on the floor this product did not work. THE PRODUCT SHOULD NOT BE RATED 1 STAR!

    3 of 5 Stars   not that effective
    By Maggie on 03/12/2012
    Verified Purchase

    I read very good reviews of this, and I have a problem of roaches in my apartment. So I decided to give it a try.It turns out that this can kill the adult roaches, but for young, small roaches, it is useless. There are still a lot of the young roaches crawling around!!! A little disappointed.

    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.

    5 of 5 Stars   Great solution for carpenter bee problem
    By Greg on 06/14/2011

    This stuff works great. Followed the instructions which were very easy and after application the problem (carpenter bees) were gone in 48 hours. Here we are 2 weeks later and no sign of them.

    5 of 5 Stars   So far...so good!
    By David on 10/05/2012

    For some reason, we had a little roach problem around our house. Lord knows I can't find any food here, and a roach wouldn't fare any better...so who knows? Anyway, I had read on one of the "how-to" sites about how to get rid of the roaches, and that person mentioned Demon. I've purchased from Do My Own Pest Control before, so I came back. I mixed up ONE batch of this stuff and sprayed the perimeter of the house (outside) and even sprayed some in the attic over an area I suspected that ants were entering. All I've seen lately are the ghosts of ants and roaches which once lived here, so yes....I highly recommend Demon, and the prices from Do My Own Pest Control can't be beaten. Thanks!

    5 of 5 Stars   Wish I could post a picture A+++++++++++
    By Teresa on 01/11/2014
    Verified Purchase

    I wish I could post a picture of what I found the next morning in my kitchen after spraying Demon WP. The other reviews stating that a white residue is left once dry is correct. However; I would deal with cleaning up any white residue anyday over seeing another roach. I did notice after spraying the roaches came out right away and I thought the stuff wasn't working, the roaches were walking right through the stuff. But to my delight they were dead by morning. It's been about a week and this stuff is still killing. I would recommend this product to anyone who has a bad infestation of roaches. Forget the so called professionals - do it yourself.

    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.

    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.

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.

    5 of 5 Stars   Great Stuff
    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   Works GREAT
    By David on 01/25/2010
    Verified Purchase

    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.

    5 of 5 Stars   Demon WP Insecticide
    By Steve on 05/21/2010
    Verified Purchase

    Found it easy to use in a pump up sprayer, the dissolving packets make mixing very easy and never had to come in contact with the product itself. Just sprayed around the house yesterday and already seeing results. Much less expensive than hiring bug company and only takes about an hour.

    Just began using Demon WP 2 weeks ago. I have not seen one insect since I applied it. Be careful, it does leave a white residue, but no problem to wipe up in a few days after. ROLL TIDE ROLL

    By Larry on 09/07/2010

    I have used Demon in the past that I purchased from the local feed store. Because I could buy in a 1 lb jar - much cheaper than the packets.

    5 of 5 Stars   Fantastic stuff
    By Ed on 04/14/2010
    Verified Purchase

    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.

    5 of 5 Stars   this is the best stuff ever!!
    By Koren on 10/21/2010

    We live in an old farm house and when we moved in back in early Fed '10 they had those Japenese Lady bugs, we have farm land all around us. I bought the winterize package from DMPC and had them wiped out of the house in about two months. When spring came of course any remaining bugs left to go feast on the nats and fruit flies so we were fully bug free. Then they harvested and back they came only this time I had already done two doses of Demon WP all around the perimeter of the house and out building. So they never stood a chance. I am happy to report we are still bug free and have not had to spray in the house. The key is to get the outside taken care of really well I believe in the over kill method, ever inch of your home needs to be taken care of from attic to basement. Windows are another source of entry so dont forget about those. You will not be disappointed, just keep in mind you may need more than one application.

    3 of 5 Stars   Carpenter bees
    By Wayne on 05/05/2010

    Used the product to stop carpenter bees from boring holes in the log siding and facia board of my cabin. I found the product to work, but the problem was the bees would fly around until they found a small place you missed about the size of a quarter and bore a hole.  When you're doing a whole house with a pump sprayer it is very difficult to cover every square inch.  So my recommendation would be to use something else to put the product on with but this would be very timely.

    3 of 5 Stars   Seems to work okay, BUT
    By L. on 02/23/2016

    It was very easy to prepare, and it's only been two weeks since we sprayed so can't say how effective it is yet. However, we have hardwood floors and this stuff spots everywhere it hits the floor. We had to go back and dry mop the entire floor after it dryed. It comes up easily enough, but that's really not what I wanted to do.

    By Matt on 06/13/2011

    Applied a barrier around the outside of the house, and in the garage. Have found a number of dead roaches, and haven't seen a single living roach in the house. Good product!
