    5 of 5 Stars   DEMON WP - Update
    June 10, 2013

    June 6, 2013 (updated review) This is an update to our initial review (below). It is now approximately 1-year and 3-months since the first application of Demon WP. We recently applied another application of Demon WP (outside only), not because we were seeing any critters, but 15-months seemed like a long time. 15-months on one application fits my schedule very well and what a good insecticide should do! We might try stretching to 18-months before we apply again. AWESOME PRODUCT! TRY IT - You're wife, your wallet and your free time will be glad you did! March 25, 2012 (original review) 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 an 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.

    This product is very good for residential apartments to prevent bed bugs and roaches. I highly recommended to landlords.

    3 of 5 Stars   not that effective
    March 12, 2012

    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 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   Great stuff for Wolf Spiders
    March 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   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.

    3 of 5 Stars   Carpenter bees
    May 5, 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.

    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   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   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   The GREATEST!!

    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.

    5 of 5 Stars   There is hope!
    October 7, 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   Wish I could post a picture A+++++++++++
    January 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.

    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!

    Used this product one time. Only sprayed outside of home and around windows and doors. All ants and spiders are gone. Ants had begun to get inside my home, but no more. Thanks.
