    5 of 5 Stars   Not just for RV's
    July 13, 2010
    Verified Purchase

    I learned about this product when I was working for a KOA campground. It was the most effective preventative for the unique pest conditions we saw with the RV's in the park. Nothing got past it! Now I own a home in a notoriously roach-infested area, and use Demon WP faithfully once a quarter. I've had the home 5 years and have never had to call a pest control company. I highly recommend this product for effective pest prevention!!

    1 of 5 Stars   Did Nothing
    September 7, 2011
    Verified Purchase

    I used Demon WP on ants. It did absolutely nothing to stop them. 30 minutes after I sprayed they were trekking across the path that was coated with Demon. So, I mixed another batch (double strength), and sprayed again. Immediately after it dried they came marching again. In my experience this product has zero effect on bugs. Complete waste of money.

    4 of 5 Stars   demon: sending bugs to "you know where"
    September 7, 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   An Unbiased Experiential Review
    April 8, 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.

    5 of 5 Stars   Roaches BEWARE!!
    January 8, 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   Outstanding Results from initial treatment
    September 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   The Right Stuff
    October 1, 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!

    5 of 5 Stars   Demon experience
    April 9, 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   Demon WP Works
    June 20, 2012

    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   Very Pleased
    March 12, 2011

    I received the Demon WP about 6 days after I ordered it and considering that I ordered on a weekend, I thought this was timely. I called customer support to ask about the date on the one pound jar and discovered that it has a five year shelf life from the date stamped on the jar. Despite spending thousands on professional extermination, we have had brown recluse spiders since 2004 and we have found that Demon WP coupled with spider traps placed in strategic locations in my home and garage have given us relief. Spraying around the exterior doors, windows, porches and taping my doors have helped tremendously. I also sprayed thoroughly inside and found that it does not stain my light carpet. I used it on my wood floor by soaking a sponge mop in the product and lightly coating the wood. This prevented white spots on the dark wood that spraying causes. I am pleased with the product and will order again.

    5 of 5 Stars   Demon WP
    September 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!

    1 of 5 Stars   Uh... me don't think so!
    October 24, 2011
    Verified Purchase

    This product has shown no result whatsoever, and it was pretty pricey too! I have been using it for about two weeks now, nothing! The roach problem is still... well... a roach problem! I decided to give this a shot, since I read so many good reviews. It's too unfortunate I can't return the product since I've already opened it!

    5 of 5 Stars   GOT THEM CRITTERS ON THE RUN
    November 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.

    1 of 5 Stars   Poor Product
    March 22, 2012

    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!

    4 of 5 Stars   Moderate Roach Problem
    August 8, 2011
    Verified Purchase

    My wife and I moved into a "new to us" 100 year old stone and mortar home 5 months ago, with a heavily wooded yard. We have had a moderate Oriental Roach problem (6-8 total in the house in 5 months, 12-15 a night outside the house). After hours of studying and consulatation from DMOPest control, I purchased the Demon WP. After 1 day of application, I found 15 dead roaches outside and 3 inside. 2nd day, 1 inside, 3 outside. It has been 3 days and have not seen any. I used the Demon WP along with the Gentrol IGR and Advion bait. 1 week today and we are very pleased with the results so far. I will spray again in 30 days.
