    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   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.

    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 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.

    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   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.

    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

    5 of 5 Stars   Roaches BEWARE!!
    By Grace on 01/08/2012

    This stuff is AMAZING! I just sprayed the interior of my home about an hour ago, and i am already amazed at the difference. I encountered a few roaches crawling up the walls and under the couches while spraying, so i figured why not give them some direct contact with Demon WP Insecticide? It was beyond imagination how quickly it killed the roaches. They were dead before you could even blink an eye! After enduring such a horrendous roach problem for the past year, this is like Christmas morning for me. I can't wait to get up in the morning and see how many dead bugs i have!

    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!

    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.

    I've been a customer of DMOPC for awhile now. If you've got vermin in or around the house, you're at the right place! Just search for your solution to pests. And, make "pests a thing of the past"!

    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.

    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.

    4 of 5 Stars   Great residual for crickets & roaches. Zero Scorpion kill
    By Dr on 09/12/2011

    Poison wiped out all crickets and roaches. Going on 3rd week without any sightings. Ants worked trail though residual. Works better when directly applied to ant colony with a good hose soaking. Has little effect on scorpions. Adult and baby exposed to 2x concentration suggestion. Made them a little drunk but back to normal in 2 days. Overall, happy with purchase. Continuing with blacklight and torch method for scorpions. Scorpion counts have dropped probably due to no crickets. Neighbors complaining now about scorpions.

    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.

    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.

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

    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!

    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   Use of Demon for roach control
    By John on 05/17/2016

    I have used Demon for roach control for a very long time. I have not found any product that performs as good as Demon for control of roaches in my house. It remains effective for a long time,and if label directions are followed,it is safe for use inside your house. Besides being effective it is economiclal to use also. Complete name Demon WP
