THE BEST. Don't waste your money on any other insecticide. Excellent.
A professional exterminator told me about Demon, probably 20 yrs ago. Been using it ever since. The ONLY DIY way to go. You won't use anything else after you try it. Buy a 2 gallon plastic tank sprayer for $15 and drop a packet of water soluable Demon into it. It annihilates ant hills, termites if you have them, fleas, palmetto roaches like here in FL. Fortunately, they die a swift death with Demon. Spray it around the outside of your house as well. Or put it in a hose end sprayer if you have a flea problem in your yard. Guaranteed gone. Spray some behind your refrigerator and range, etc., if you notice a roach, but you won't after using this stuff. Oddly enough, if you spot spray your cabinets under the sink or closets, my cat has never been affected.

Affordable DIY Pest control that works!
This is the BEST. I fired my pest control company that had to come every 3 months, at a cost of $300 a year. After using this once, I noticed 18 months had gone by, and still no Florida palmetto bugs. To make sure my place stays that way, I use this at the beginning of rainy season every year.

The Best
I was having problems with ants. It’s like they were getting in everywhere but specifically in my bathroom a girl I worked with told me about this stuff. She said I’ll get my husband to come spray it for you. I said great. I had a sprayer I bought the stuff he came and sprayed it. The one thing you have to be sure that it’s not wet outside and it hasn’t been raining. It has to be dry as long as it’s dry. You spray this everywhere outside he could see everywhere where I needed it but he sprayed everywhere not only does it kill ants. It will kill anything roaches ticks fleas termites. Anything this stuff is wonderful. He sprayed it all under my house all around my house. I live in the country. There are fills everywhere so he sprayed it all around my house and then he went in and sprayed it in my house, it works awesome you don’t need a bug man anymore. If you have this stuff, it works !! no more ants have not seen any ants, not only didn’t kill him outside, but it killed him inside. That’s why it counts. I think you definitely get your moneys worth no doubt about it. I like it so much. I bought some from my uncles house and a sprayer he has ants really bad at his house. I’ve been spraying all outside next. I’m gonna get inside just to be sure there are no critters around! Stop paying those pest control people and buy this and Do it yourself you will save a lot of money!!

Texas Approved
Moved to a new house in Texas. First warm season we got brought hundreds of spiders. Had jumping, huntsman, and ton of brown recluse coming into the garage, and making their way through the soffits around the roof. They were also crawling all over the fence from the neighbors property. Tried everything we could find at the depo stores but nothing was working. Talked to a pesticide guy and he recommended to find something with Cypermethrin in it. This is just below the professional grade where you need a license to purchase and it works FANTASTIC. I spray once every 2 months around the outside of the house in warm weather (outside walls, fence, driveway, garage) or after a few heavy downpours. Haven't had a problem since. Both neighbors on both sides have spiders and webs everywhere, but my house has nothing on it and I can walk my grass without encountering anything aside from a stray flying bug once in a while. I also love that I don't have to worry about measuring (1 gallon sprayer and 1 packet) and covers a 4000sq easily and that's me spraying heaving in some area like the fence so it soaks. Would recommend!
