    5 of 5 Stars   Best product Ever
    By Amy on 07/09/2016

    I have used many organic sprays that smell horrible. I have used many regular sprays that you know they are not healthy to use in the house. But Demon is the only one that works as fast and effective without the smell.

    5 of 5 Stars   Demon experience
    By Jim on 04/09/2014

    Used the Demon in front of my garage and doors. Next day dead bugs that never got beyond the Demon. Very fine powder so be careful when you open the container because it will start to float out. Where a mask or just be careful and slowly open it.

    By Casey on 06/17/2016

    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.

    1 of 5 Stars   A "NO-GO"!!
    By Barb on 08/14/2012
    Verified Purchase

    I sat on this website and read all 300+ reviews. I was truly convinced that this product worked. Anything with the name Demon on it suppose to kill everything. This product didn't even kill the local ants. As a matter of fact, my bug problem (spiders, roaches, ants) actually got worse. i need some help. i need to get rid of these insects before they get bold and crawl in my families ears'. So what product REALLY works.

    5 of 5 Stars   The GREATEST!!
    By Gordon on 04/22/2010

    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   Great Stuff
    By Reta on 12/01/2014
    Verified Purchase

    Roach free for almost three years now. Keep on hand to control spiders and other insects in the home. Just spray once every six months. Also great for keeping wasp, yellow jackets and other bees from making a nest around the outside.

    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.

    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.

    1 of 5 Stars   Poor Product
    By P. on 03/22/2012
    Verified Purchase

    I tried the Demon WP Insecticide on an Earwig that I caught inside my bathroom. I used two packs of the Demon WP 4 pack mixed in 1 gal sprayer of water. The product did not kill or slow the bug down and it was in a cup at first and then on the floor this product did not work. THE PRODUCT SHOULD NOT BE RATED 1 STAR!

    3 of 5 Stars   Seems to work okay, BUT
    By L. on 02/23/2016

    It was very easy to prepare, and it's only been two weeks since we sprayed so can't say how effective it is yet. However, we have hardwood floors and this stuff spots everywhere it hits the floor. We had to go back and dry mop the entire floor after it dryed. It comes up easily enough, but that's really not what I wanted to do.

    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.

    5 of 5 Stars   Demon WP Absolute Bug Destruction
    By Tim on 05/02/2012
    Verified Purchase

    I Sprayed this on the outside foundation of the house, door frames, window frames, kitchen and bathroom cabinet bases, etc. Demon WP, Gentrol and Maxforce FC Magnum bait totally decimated a 20 year fight with German roaches that I've tried to kill with everything locally available. It's been about two weeks and I'm still Amazed..thank you for an amazing product, good prices and fast shipping.

    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   Demon WP 1 lb jar
    By Jr on 05/20/2010

    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.

    4 of 5 Stars   Great residual for crickets & roaches. Zero Scorpion kill
    By Dr on 09/12/2011

    Poison wiped out all crickets and roaches. Going on 3rd week without any sightings. Ants worked trail though residual. Works better when directly applied to ant colony with a good hose soaking. Has little effect on scorpions. Adult and baby exposed to 2x concentration suggestion. Made them a little drunk but back to normal in 2 days. Overall, happy with purchase. Continuing with blacklight and torch method for scorpions. Scorpion counts have dropped probably due to no crickets. Neighbors complaining now about scorpions.

    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   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!

    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   Use of Demon for roach control
    By John on 05/17/2016

    I have used Demon for roach control for a very long time. I have not found any product that performs as good as Demon for control of roaches in my house. It remains effective for a long time,and if label directions are followed,it is safe for use inside your house. Besides being effective it is economiclal to use also. Complete name Demon WP
