    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.

    3 of 5 Stars   not that effective
    By Maggie on 03/12/2012
    Verified Purchase

    I read very good reviews of this, and I have a problem of roaches in my apartment. So I decided to give it a try.It turns out that this can kill the adult roaches, but for young, small roaches, it is useless. There are still a lot of the young roaches crawling around!!! A little disappointed.

    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.

    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

    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   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   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   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   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   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   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   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.

    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   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!

    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   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!

    I have used Demon WP before and it is the only insecticide I use. It will keep working six months or more. When you purchase this product you won't need anything else.

    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.

    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!
