    It has been almost a month and so far no pesky pest seen. I will do another update in another month or so.

    It is not doing the job, I have sprayed numerous times and I still have roaches. I used to use Demon but it is not the same result.

    5 of 5 Stars   absolutely amazed
    March 14, 2012

    I have had people come out twice to my new house 300 dollars worth. This house is invested. I mean open any cabinet and roaches fall on you. they were in the walls everywhere. I bought a 1lb jar of demon and a 1 pint jar of gentrol. Now Im living here with two kids!! I soaked this house down about 5 times. The roaches are gone and have stayed gone in less than 6 weeks. Those two are the greatest thing I have ever seen. My whole family cannot believe it. They want me to be their pest control guy. Thank you so much for this website. I payed the 25 dollars and got my stuff in 2 days. It showed up and works on spiders,roaches,fleas,wasps,hornets,even garden bugs. Im not sure it was recommended for that, but I love this stuff.

    5 of 5 Stars   Demon WP vs german roaches
    March 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!

    5 of 5 Stars   Nail box elder bugs
    March 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   Fantastic stuff

    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   First time user on the Outer Banks of NC
    August 20, 2013

    As a former farmer for many years, I am accustomed to working around chemicals and had no problem mixing and using the Demon WP I purchased in a one-pound container. It mixed easily. I was primarily spraying for cockroaches, and it did the trick. Before I finished spraying aound the house, I was seeing dead and dying cockroaches on the ground. We also had a centipede issue inside our beach house, and that was also eliminated. The chemical worked for the insects we were targeting and I plan to use it again. Unless I am mistaken, I mixed around 8-10 one gallon sprayer loads at the higher recommend rate for my 3K sf home, and there was enough material for another treatment remaining. My purchasing experience was also good, and the product arrived sooner than I was expecting using normal shipping. I don't normally provide feedback such as this, but this was a much better than usual experience of purchasing a product online.

    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.

    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.

    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   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   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   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   Good Product

    After using the product, found 3 dead roaches in the garage, 4 on the front porch, along with multiple spiders around house. Would highly recommend.

    4 of 5 Stars   Works as advertised
    May 16, 2011

    I have made one application of this product around my home and have a noticeable difference in the amount of insects. The best thing is my local pest control company was going to charge me more than this product cost for one treatment and now I have years worth of protection for little cost!  Application was easy and simple and leaves no visible residue or smell.  I recommend this to anyone thinking about doing their own pest control. Truly is simple and will save $$$.

    I bought Demon WP and used it on our infested garage. Within a few minutes there were several dead and dying bees on the floor. We had wood borer bees all over the place. Every place I sprayed has been free of insects for a year now. I am going to order more and spray everything around the house to keep these bees under control. I would highly recommend this product.

    5 of 5 Stars   So far...so good!
    October 5, 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!
