    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.

    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.

    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   The Right Stuff
    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!

    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.

    Expert Response  Expert response:
    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.

    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

    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!

    5 of 5 Stars   Roaches are gone
    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!

    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   Demon WP 1 lb jar
    By Jr on 05/20/2010

    I use it for a large number of home invading insects. It works very well and is not noticeable in the home. I would recommend to anyone who likes to do their own pest control.

    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.

    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.

    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.

    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!

    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.

    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.

    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.

    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.

    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

    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   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!

    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"!
