    1 of 5 Stars   Demon wp strikes out
    By D on 04/20/2016

    Highly disappointed in product. Used concentrated with poor results. The product was ineffectual against roaches. Maybe I got a bad batch but hoped by the reviews that it would at least kill some of them.I followed the instructions fully but after ten days have only seen three dead roaches. I would not recccomend this product. If the batches are sold in different strengths for different states this batch was a dud.

    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!

    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"!

    1 of 5 Stars   Kills on contact but that's all!
    By Denise on 06/26/2016

    The WP packets killed as long add the spray was sprayed on them directly, but I haven't seen any dead ones from the residue after a week of looking.

    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.

    1 of 5 Stars   Did Not Work
    By Bob on 02/12/2013
    Verified Purchase

    After using the 1st. packet it did not have any effoct and tiny roaches kept appearing. After one week I used the 2nd. packet in just a little stronger concentration and it was again useless. The roaches just walked thru it with little or no effect.

    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.

    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   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   BUY IT!!!
    By Buzz on 05/16/2016

    I bought this because of the reviews, but found out about it from my brother, who met a guy on a plane who told him how great it was. I live in Central Florida, and I had cockroaches, palmetto bugs, spiders-the operative word there is "had"! I sprayed this stuff around the entire exterior of my home, then hit the door frames, window frames, trouble spots and the travel routes (bathroom, kitchen, under the stove and fridge) inside...and I have NOT seen a live bug in two weeks, but I have vacuumed up lots and lots of dead ones! It's inexpensive, easy to apply, and it most definitely WORKS!

    Demon WP is extremely effective in treating insects issues. I see the same results with Demon that I'd seen with using insecticide companies. It has definitely saved me money.

    5 of 5 Stars   Amazing
    By Doug on 08/06/2016
    Verified Purchase

    Recently moved into an older house that has been empty for a couple years. Saw and killed several brown recluse. Pest control came and sprayed for $80 and it did nothing. Read the reviews for this and decided to give it a try. Mixed according to directions for spiders and sprayed all along the baseboards inside the house, garage, and along the outside foundation. Opened a few windows and left for a couple hours while the house aired out to let the product dry. Upon returning I found a dead scorpion at my doorstep lying on the line I had sprayed. Absolutely fantastic product and worth every penny.

    1 of 5 Stars   It's okay if you want to drown them.
    By Daphne on 08/16/2012
    Verified Purchase

    We used this product last week and other than making a huge mess when it dries, all it did was drown the roaches at our house. I bought this product hoping it would wipe out our bug problem, not only here but at a family members home too. Instead I wasted my money on a mess to clean up and can't even help out the family member.

    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.

    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

    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   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.

    5 of 5 Stars   The Last Word in Pest Control
    By Steve on 06/27/2016

    We moved into a house that had been vacant for several years. The grass was high, and the bugs were coming inside. My wife was calling the pest control company to try and stop the scorpions when we happened on DemonWP at Tractor Supply. Here it is- this stuff works. Spray liberally and let it dry along the outside of the house, and the bugs will be lying dead where you treated. Inside, I sprayed the baseboards and entry areas. The scorpions found inside are in the spray area, and are dead. I have no bugs, from roaches to scorpions to ants to spiders, it just works. Buy with confidence, you will not be disappointed.

    5 of 5 Stars   Kills them dead and keeps killing them
    By Ivan on 07/22/2016

    I ordered Demon WP insecticide for my folks and myself because with all the rain we been having things were starting to crawl around like they owned the place. I doubled up and put two packages in the mix instead of one and I am more than happy with the results. The few that I have seen may crawl but they are not crawling fast instead they are doing that pretty little death twitch I enjoy seeing them do. Sprayed the outside windows panes and bricks where I saw ants marching. They are now in full retreat. Thank You Demon WP.

    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!
