    Took care of our scorpion problem

    By Michelle on 07/05/2015

    Product was easy to use and so far since spraying the foundation and 3 feet up the side of the house no scorpions have gotten in. I only gave 4 stars because I do not know how long the protection will last. But 5 stars if I never see another one in the house!

    Worked Great, Just Not Fully

    By Anonymous on 06/04/2013

    Verified Purchase

    I'm not sure if I did something wrong but I mixed up the "knockdown" method of two packets in a gallon of water and sprayed it all around outside my house, under appliances, along baseboards, etc. Seems to have worked fairly well but I still have a few bugs that make it on the counter-tops and around my Keurig.

    Demon WP

    By Anonymous on 06/09/2013

    Verified Purchase

    After using this product, thus far, I am pleased. I used it according to the directions, and have seen a significant improvement in the bugs crawling inside and outside the house. I had a flea infestation and that has diminished to almost none. I will continue using this product, it works better than the commercial products that you buy from local home improvement stores.

    MB Demon WP (Myrtle Beach)

    By Dan on 05/21/2011

    Verified Purchase

    I am happy with this product BUT would like to find something that does a better job. It did work better when I originally applied it. Now perhaps there is some tolerance to it. The company and the shipping are first rate. Would like to know of a better product

    Great product

    By Ronay on 09/11/2013

    Verified Purchase

    It does leave a white residue on the floors and walls, which is why I only gave it 4 stars. The product itself is great, the bugs where falling as we were spraying.

    WP Demon Insecticide

    By Thomas on 10/24/2013

    Verified Purchase

    We use this insecticide to rid ourselves of STINK BUGS....and prevents them from coming in our RV 5th wheel...for the most part. We spray this insecticide all over the outside of our trailer, under the rubber seals around our slide outs, all under the trailer, sides, top and all around every vent on the roof. And once this spray dries we have a white powder-and we see dead stink bugs on the outside rug every day for 2 weeks or more! Good stuff!

    Demon WP Insecticide

    By Monica on 11/30/2013

    Verified Purchase

    I really can say that this product works well as a residual pest control in a 4-unit apartment house. Even in my own home I've applied it around my house as a barrier treatment. The next day, outside, I would see a couple of dead roaches outside the house. However, I still seem to find a roach or two in the kitchen every morning struggling, that may have come into contact with a previous pest control treatment. That treatment does not kill them, but leaves them struggling & half-alive. But the Demon WP KILLS THEM!!!

    Great stuff!

    By A. on 05/22/2012

    Verified Purchase

    I heard about Demon WP from someone at work, I have to say I didn't hold out much hope of it being a great product, mainly because I had never heard of it and the low cost. I started outside spraying around the perimeter of the house, by the time I got back to where I started, bugs were coming out of everywhere dying. I then sprayed inside the house. It's been about three weeks since application and I have to say, I am not seeing the normal traffic of crickets, beetles, and even spiders. I am very pleased with the performance of this product, and I know I will be using it again. My one concern is that I have wood floors, so, when I vacuum the powder from around the edges of the rooms, I have no way of knowing that the insecticide is not being transferred into the air.

    Die Stink Bug DIE!!!

    By John on 10/11/2010

    This product does exactly what it said it would do. It kills them and keeps on killing them. It does not kill them immediately but does do the job in about 8 hours. Wave after wave of the little stinkers kept coming and so far it has killed all invaders. The product does leave a light film but it should wash off. The proof for me will be when the warmer months arrive and whether we see them inside our house. This is the only reason I gave it 4 stars. I will add to the review in the spring and hopefully will be adding a fifth star.

    Demon WP Did the Job

    By Daniel on 09/21/2010

    Verified Purchase

    I am very happy to finally get a "do it yourself" product that actually showed some results. The watered down products I was getting from the home improvement stores had no results what-so-ever. The Demon WP did exactly what they said, killed everything I wanted dead. I haven't found anything that works since they outlawed Dursban, but this did. My only complaint is that it is visible on my black metal fence, it is a light brown cloudy solution. I am satisfied.

    Demon is pretty good...I must say.

    By Honesty on 10/12/2018

    Demon is working wonders. You really have to follow the directions however. I am using it low on baseboards and in cracks and crevices due to a pretty bad roach issue my neighbors have and now I have (duplex). I read another review of this product and it says it drives them to higher places if you use it low. Which it very MUCH does. So when they DO start to be on counters etc as a mechanism to get away from the Demon, that is when and where you need to have out the bait at. We are using Maxforce and Vendetta Plus (it has IGR in it) gel bait. Cabinets. Counters. Under the microwave. Our drawers. Finally I Cimexa'd the mess out of all of my outlets and my "up high" cracks and crevices. With the Cimexa dust I had on hand. Only a few stragglers left. We also used Demon on our outside perimeter. Its working. Two heavy rains now due to hurricanes but plan on doing another outside treatment this weekend. Its fall and again has been damp. Dont want to give any crawlies the thought that this is their winter time place of residence.

    Demon WP uses at home and at work

    By Richard on 09/20/2012

    Verified Purchase

    I got the recommendation of this insecticide from a friend who swares by it. I am very impressed at the different types of insects it kills. Home use: I am currently having a battle with fleas in the house and was not sure this was what I needed but I figured I would give it a try. Used by itself it works wonders on the adult fleas but in 7-10 days the new hatch starts up. So you definately need to use this in combination with something that inhibits the groth and life cycle of the eggs/larvae. I was also suggested Precor area spray for this purpose. So far so good. I also have silverfish/earwigs in a great abundance. This takes them out with no questions asked. Work use: I also wanted to use this in the warehouse that I manage. There have always been "daddy long-legs" and other various spiders as well as the larger roaches called "waterbugs" down here in the south. I sprayed a 40' perimeter around and in my office almost 2 weeks ago and am continuing to find new dead bugs all over. The only reason I gave this 4 stars is because of the ineffectiveness on the "daddy long-legs". Apparently they are pretty resiliant to this and require something else to take care of them. Overall I am pleased with this product and will continue to use it. Also being that it is one of the cheapest and dealing with DoMyOwnPestControl.com is so easy.

    So far So good!

    By Crystal on 08/24/2011

    Verified Purchase

    I used this product about a month ago and I must first state that I live in a town home. I'll never be rid of all bugs unless everyone treats at the same time. BUT I have noticed a huge difference in the amount of spiders and creepy crawlies hanging around my door and other areas. Right now, there are no spiders anywhere unless they're hiding! (I'm sure they are) I have only treated the outside and spot treated 3 spaces in my basement. I've only found one or two crawlers in my basement since but with spot treating, who knows if they walked across the dust. This product definitely does kill black widows as I found out through spraying that I actually had some. Unfortunately I can't vouch for watching what it does to the bugs, but I know that upon directly spraying them they die within minutes. I used 2 packets per gallon and made two gallons. I had enough to spray my townhouse front and back, the back of my friends house and the entire perimeter of my mothers single family home with some still to waste on the last gallon. I was a little spray friendly with my first application b/c there were so many bugs. All in all, I like this product and I'm def going to buy more for a spring application. I like that you can buy 4 packets for $13. Especially since I have such a small area to deal with. We'll see how long it takes for the bugs to find their way back to my front door :)

    My experience with Demon WP

    By Marjorie on 06/04/2011

    Verified Purchase

    I was introduced to Demon WP by my son who lives in Orlando where bugs are quite plentiful. I am a widow with a 100 yr old house that has been in the family since 1940. Once an old farm house, it has been renovated (finished by my dad in 1980) and many houses have been built up around it. This is my second order of Demon WP and I have just sprayed around the outside of the house and will do the inside in the next few days. The last time I did this, I had no problem with cockroaches, or other insects for more than a year. If I found a bug, it was already dead. Carrying the sprayer around is a bit tiring for me but the effects are worth the trouble. I don't worry about going in dark closets after I spray all the baseboards and crevices. The termite service man said they were not allowed to use a spray that strong. Thank you for Demon WP.

    It works!

    By Leah on 09/18/2011

    Verified Purchase

    I followed the directions on the package and mixed the insecticide powder with water and sprayed around my house outside and inside. Within 2 days I began seeing dead bugs both indoors and outdoors. I saw two live bugs the first week that I sprayed and haven't seen any since! The smell is strong when you spray so I would recommend leaving for awhile if you spray indoors.

    By James on 11/08/2011

    I got the insecticide to kill crickets and it did a great job. The only problem was if you get the little package wet it will melt fast and makes it hard to put the contents in the sprayer.

    This product works great! It kills on contact inside and out. It works on all types of creepy crawlers (spiders, roaches, pill bugs, etc.) This last batch I bought left white residue. It has never done that before. I was easily wiped away without any damage. Despite the residue, I will continue to use it and definitely recommend this product to anyone with bug problems. Let's see, bugs in my house or white residue?....You choose.

    By Natasha on 10/06/2010

    I have enjoyed using this product. It has worked very well. The problem I am having is that I might have a bigger problem than I thought and I might have to call in some professionals. I would very much recommend this product to anyone who does not have an infestation. I did start to see dead bugs within 24 hours after use and I am still seeing dead bugs every day.

    Excellent buy Killer even if a bit expesive

    By John on 07/30/2012

    I made up the whole jar in a 2:1 ratio for scorpions and wasp since I had seen a few around the place and week prior had killed a black widow. I want to say I made 45 gallons of spray at this ratio and had about one scoop left over for hand held spraying. Critters do not die right away, but they do in 30min to an hour. I found grass hoppers, wolf spiders, ants, moths, and wasp all lying around the yard hanging out dead. It's been 3-4 weeks since sprayed with a power washer and have yet to walk thru a spider web in my heavly wooded yard at night. Expensive, but it works. Mixes easy enough and has no oddor and easy to measure out. Comes in a plastic seal around the cap plastic jar and keeps it dry.
