    Doing the job!

    By Erica on 01/29/2021

    The reviews were accurate on how well the solution work. I only see dead ants and also kills all other insects. I am bug-prone, honestly wish they would just disappear altogether. But, it's better than seeing them in my cabinets and crawling up my wall. Not comfortable with placing snacks in the cabinet just yet. Don't hesitate to buy it does work No Doubt!!!!

    The Best Spray Ever

    By R.a. on 02/19/2021

    Demon is my go to chemical for roaches in abundance. The residue it leaves behind works great with killing roaches and various critters.

    Roaches seem to be gone

    By Melanie on 03/05/2021

    We moved into a place a couple of months ago, and started seeing a roach here and there. We had always heard that if you see one, then there are probably has hundreds ir thousands, of hat you can't see. So, we wanted to get ahead of the problem, if we could, and ordered the Demon WP. After spraying with Talstar P, then spraying with the Demon WP, a month later, we saw a few dead roaches, at first, but thankfully haven't seen a roach, at all, in a couple of weeks now!!! Do, we are sold on both of these products!!! We have been using Talstar P for 2 or 3 years now, and never had a bug, of any kind, at our old place!! These products are the real deal, and we won't use anything else!! Plus, it saves a fortune, because we no longer have to pay the professionals to spray for us!!! Thank you, #domyown for excellent products, and fast, easy, and knowledgeable service!!!

    Demon etal

    By Tj on 10/01/2021

    I live on a 42' houseboat in a marina on the Gulf of Mexico just outside of Corpus Christi, TX. Being on the water the location is absolutely infested with roaches. That said, I am, apart from a couple neighbors that I have sent to Do My Own, one of the very few boats with a zero roach problem. Regardless of how bad it is, you can beat the roach problem if you turn to Do My Own and follow their guidance.

    This is the end-all

    By Terry on 11/16/2021

    Living in a townhome, you're not just concerned with your own home, but also what the neighbors have. And in North Carolina, roaches outdoors will find a way in, especially when it starts getting colder. I used another product from Do My Own (advion) and it was okay, but it doesn't stop anything from coming inside. They just eventually die once they're inside and take the bait. Nasty. I tried Demon WP and used the recommended sprayer to apply it. It was easy to mix. I sprayed along the foundation outside and used the fine spray setting on the baseboards indoors. The next day I saw 3 dead roaches on the patio. And since then absolutely no roach has been seen in my home - dead or alive. This is the stuff. It works!

    Carpenter Ant Nuclear Blast

    By Enrique on 06/12/2022

    A few carpenter ants showed up taking their last breath after the application of the Demon WP. ( Actually carpenter ants do not have lungs ) Since then all the areas that I sprayed are clear !!!!! Will be on the lookout to see how long before they start showing for another feeding of the Demon. This is going to be my chemical warfare weapon for this enemy.

    Effective Treatment for Roaches and Carpenter Bees

    By Malcolm on 04/22/2023

    Used this last week inside and out. Inside for roach barrier around entrances and outside where I had Carpenter Bee activity. Effective for both. Only downside is that it leaves a white residue on both. This was most problematic inside on our dark hardwood floors. After it dried, had to wet swiffer the floors to make the wife happy. I'm starting to look now for another roach control product I can spray indoors without the powdery residue.

    I bought this from 2020, 3 years later and it still works!

    By John on 09/19/2023

    Verified Purchase

    This product will never seize to surprise me. I used 2 packets during the pandemic because we were having a lot of insect problems and I didn't get to make a review then but I remember when I woke up - dead insects everywhere. It stayed like that until it rained then things got washed up and I didn't to apply again. This year 2023, we've been getting all sorts of insects but mostly spiders, they've invaded our backyard, garage, restrooms even rooms. So I decided to spray the two leftover packets from 3 years ago and HOURS later - dead spiders everywhere, black widows, false widows, long legs you name it. Pill bugs, ants, etc. Right when it dried they all died. The label says I could use 1 packet for basic maintenance so I'll probably try that and see how strong 1 packet would do but two is the answer for your problems - it still leaves a white residue, its not as noticeable on lighter surfaces but be careful where you spray it, you don't wanna spray it on a black or dark surface.

    Best ant control I have ever seen

    By Don on 11/10/2023

    We had an ant issue here at our home in Central Texas this summer. Keyword: "Had": I used Demon in the past and it was amazing. Recently, I tried to save money by using other products, but the ants basically laughed at me. I went back to Demon and for some reason, they all disappeared. I'm laughing now.

    Works on Crane Flys (Large Mosquitos)

    By Peter on 04/26/2024

    I purchased this product as we have an issue with Hornets / Wasps. When I received the product I immediately sprayed inside and outside, including the entire lawn where we had a plethora of Large Mosquito (looking) bugs. They are 99% gone after one application. BTW, there are more bugs in Middle Tennessee then there are in Florida!

    Wettable powder great residual

    By Carl on 10/11/2024

    Demon water powder is an excellent insecticide for killing roaches and other other insects. It is intended to be put in a gallon sprayer one pouch per gallon and then sprayed on the surface when it dries it leaves a powder residue so when insect pit they pick it up and they start dying about 72 hours later

    Demon WP

    By Rose on 06/05/2010

    We have been using this product for at least five years and it does a great job, all the other products advertised are a waste of money.  This lasts us over two or three years as long as you use it correctly, thanks for a great product!

    Here in the high desert of Northern Arizona, the rainy Monsoon season of high humidity and temperature brings out every type of creepy-crawly. . . .the worst and ugliest of these are the Desert and Mountain centipedes. When we use Demon-WP spray solution every 3 months. The only ones we see are the DEAD ones. It really, really works.

    SHAZAM

    By Linda on 08/11/2010

    Verified Purchase

    This is the product to use, if you have problems with insects flying, crawling or sneaking into or around the house. We spray our air conditioning units outside to keep the fire ants from disabling our units. Just spray around the unit every time it rains! No expensive service calls to repair them. We also spray around the entry doors, to keep flies and mosquitoes from lingering there. No pests in the house for us!

    Nasty Stink Bugs

    By Mr. on 09/28/2010

    Verified Purchase

    Hello, I live in Owings Mills, Maryland. The stink bugs have hit our area and they are everywhere. However they are only coming into my 2nd floor sliding glass door. After using the Demon WP, the stink bugs were still coming in but they were dying off. When I look in the floor tracks of the sliding door I find lots of dead stink bugs.

    Demon WP Insecticide

    By Mary on 10/03/2010

    Verified Purchase

    This product is amazing!!! We had a proplem with aphids in our willow tree. The aphids secreted honeydew which attracted many wasps and flies. After one application of Demon WP the aphids were dead and the flies and wasps vanished.The product dried very fast. I saw amazing results the next day. We can now let the grandchildren play under the tree again, and we can all enjoy our beautiful willow tree.

    It works but...

    By Natasha on 10/06/2010

    Verified Purchase

    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.

    Very pleased

    By Carol on 10/11/2010

    Verified Purchase

    I have used a number of different types of pest control products over the years and Demon WP is by far the best I've ever used. I was prompted to purchase something more effective when my grandson spotted a (gigantic) grass spider in our basement. He watches television down there in the part that is used as a gameroom. The spider was so big that rather than trying to hit it with something he threw the remote at it. It got away. I ordered Demon WP and although we never did find the original spider he did find a baby one that looked exactly like it. It was a relief. The product did everything it said it would. The day after we treated the basement we did see a number of bugs...and they were all dead. This will be my standard product from now on and in the spring I plan to examine the rest of your line. Thanks for a great product.
