    5 of 5 Stars   Quick service thanks
    By Michelle on 06/23/2010

    I received my product much quicker than I expected...thank you.  Demon works very well. I felt as though I was being taken over by the very large palmetto bugs.

    4 of 5 Stars   Demon WP
    By Wayne on 07/07/2010

    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

    Great product. We live out in the country and have bugs outside everywhere. After spraying Demon WP Insecticide it looked like a bug battlefield outside! This product also does a great job of keeping the bugs OUT of our home!

    By Larry on 06/02/2010

    I sprayed around the out side of my house a month ago and i'm still seeing dead bugs everyday on my front porch and my patio in the back. Worth the money.

    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.

    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.

    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   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   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   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   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   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   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!

    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.

    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   Success
    By on 06/16/2013

    We purchased a home about six months ago and found out later that this area apparently has a scorpion infestation. My husband has tried several products with moderate success but was able to keep the scorpions out of the house until recently. After returning from a short trip and locating a live scorpion in one of the bedrooms, and in desperation, I turned to the internet to try to find a solution. This Demon product showed up in my search and after reading several reviews to my husband, he asked that I purchase the one pound container. One week later, he is happy to report that this product has provided the results he has sought. After spraying close to the house and around the driveway and seeing the results, he has now sprayed the perimeter of our property along the curb line and across the edge of the driveway and hasn't seen any scorpions, alive or dead since spraying the perimeter. We're definitely sold on this product and will continue to use it. We hate those little creepy invaders and are thrilled to have found the solution to them.

    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!

    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   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.

    By Cary on 10/01/2011

    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!

    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.

    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   DEMON WP
    By Greg on 03/25/2012

    Our home is in a heavily wood area north of Houston, Texas. From the first day we moved in we were seeing a lot of spiders, both inside the house and the garage. We treated the exterior with Diazonon once a year and ended the spider problem. When Diazonon became no longer available, we switched to professional exterminator services. After trying numerous different professional exterminators, and still having spiders, we tired of wasting money on the "professionals". We decided to return to DIY pest control method. After much research we decided to try the Demon WP product. We used 2 scoops per gallon and sprayed inside and outside both the house and the garage. While spraying in the garage we sprayed a medium sized spider directly. It was legs up in seconds. Upon closer examination we found it to be a young black widow spider. YIKES! While spraying inside the house we sprayed a medium sized wolf spider directly. It walked right through a puddle of Demon and just kept going. We kept an eye on him and about an hour later he was balled up dead. Interesting that this product kills black widows in a matter of seconds, but it takes about hour to take out a wolf spider. The day after application we found quite a few dead wolf spiders, june bugs and Mosquitoes outside and no critters inside (dead or alive). We'll provide an update in a few months regarding the long term effectiveness of the DEMON WP product.
