This product was recommended to me by a family member in Houston, whose has a professional come out to treat their property to prevent infestations of creepy crawlies. We had an ant problem to put it mildly. They were streaming in from the outside through the door, and through the window in the kitchen. Also had a few incidences with spiders. (I woke up to one crawling on me, and I have arachnophobia!) We were told that Demon WP is what they have their house treated with and never see anything anymore! (They have woods near their house so you know there is a chance for bugs.) I was desperate! Looked around, called around, asked around... nowhere to be found in St. Louis, Illinois, or in neighboring areas. Other products were offered, but I like to go on reviews and experience. Found it on Amazon.com, and bought the big gallon. Granted it will last for years even if I treat multiple properties, but WELL WORTH EVERY PENNY I PAID FOR IT!!! I also ordered one of those gallon sprayers. 2 scoops of Demon WP and a gallon of water... It was like a ant holocaust! Even flies that have managed to sneak into our house have came across the residue of the product and have fallen over dead within a short amount of time. I also haven't seen any spiders, wasps, carpenter bees, lady bugs, crickets, and all the other insects whose name escape me at the moment. The great thing about this product is that when it is dry it is non toxic to be around families, children, & pets! They need to put me on the payroll, because I have already been telling everyone that will hear about this product, and have been convincing people to buy it! Amazing!

To start I must mention how economical this stuff is compared to what you can buy at home improvement and big box stores. This 1lb jar of Demon WP will make up to 48 gallons which @ $50 is roughly a buck a gallon. The stuff in the stores is $25/gallon and up for the premixed "home defense". I have used it in years past and found that if you dont use up either the concentrate or the pre-mixed store-bought stuff it is useless the next year. My total investment is for the Demon WP was $62 ($50 + $12 for a dedicated sprayer). If I were using this for just my house it would last me about 8 or 9 years, but since I had 2 neighbors go in on the purchase with with me it should last about us 5 or so years.

Good points to remember:
- No smell
- Cheapest pest control
- Safe around humans and pets once dry
- one pound will last for years and won't lose potency
- easy to mix and apply
- it actually WORKS..... Period

I purchased this about a month ago because My garage was being over run with wolf spiders and I was tired of spraying the other useless and noxious smelling store-bought stuff to treat my house. The Demon WP was delivered within a few days but I was fairly busy and didn't have the time to really sit down and read about it so it just sat around for a month.... Meanwhile I had laid down a heavy layer of DE Powder in my garage (It looked like a Columbian drug lord had moved in) which seemed to take care if the spiders that were on the floor (the wolf spiders would literally line up at the edge of my garage door.....ick). Also in the meantime, as the weather warmed up, the Mosquitos returned as did the noseeums, June bugs and other critters. I absolutely hate large flying insects like June bugs and large moths...

After using the product one time we haven't had any problems with ants or roaches anymore. We didn't even use the product in the house but just used the product around the outside of the house and in the garage, etc.

I mixed a gallon of product in my weed sprayer and sprayed a small stream around the base of the walls of my house and garage. Sprayed at 10 pm and by 2 am when I got up to go to work there were dead cockroaches all over the floor. 84 cockroaches and 3 black widows dead overnight. I have not seen a live cockroach or spider in the house since the night I sprayed. I am extremely happy with the products price, speed of shipping, and effectiveness.

I have used this product for a couple of years since retiring to East Texas in the country and it works well. Did not know we had this many scorpions here.

This particular purchase was for a gift to help make a friend a believer! I have been using this product for a long time. My last jar has lasted nine years so far and I am still not to the bottom of the jar. So, if the price seems a little unseemly at first glance, consider that against how much you would pay for Raid or some such over that amount of time! The first time I used Demon WP was on a little stretch that traversed a walk-in opening to my gargage. I used to see ants at various times of the year massing there. At the time I sprayed there wasn't any trace of the ants nor did I see anything the rest of the day. The following morning, however, the area was blackened with dead ants! I haven't seen a trace of them there since! That did it for me. I spray all around the foundation to the house and all cracks and crevices every year, usually just once, and I don't have the insect and spider problem that used to exist or even anything close.

For the inside of garages and sheds, I prefer to use a bomb or fumigator as they will kill everything on the inside wherever they may be hiding. I use the Demon WP to spray a barrier across all openings and anything that crosses that barrier (except flying insects) will get inside and promptly die.

This is a professional grade product so if that makes you a little nervous, stick with Raid! It needs to be mixed with water in a pump up sprayer and it is highly recommended to wear gloves until it is mixed and the outside of the sprayer is hosed off. Since it goes in as a powder, there will likely be some dust generated when it is scooped in. Don't mix in the house and don't breathe the dust! Keep pets out of the area until the product has completely dried. Don't mix more than what you think you will use and use all of what you mix.
