I’ve been using this product since 2016. The value is great, there’s no scent, pet safe. The effectiveness is very good and takes no time to dry. Be careful where u spray it though because once it’s dry it turns white so it won’t look too good if u have colored walls or cabinets with white stuff on it. At first it will seem like it’s isn’t working and it’s feeding the bugs instead of killing them. It’s not when sprayed the bugs come out, pay attention they are running for dear life to get away but never make it out alive. The fast movement becomes slow steady then next it gone. Mark my word it’s dead somewhere belly up.

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!!

When I retired from a hospital 20 years ago, I asked the man who exterminated what he used. He said nothing but Demon. Now we say the same thing. We never have bugs in this house, and ever had them in our first house. Demon kills and keeps on killing. It hasn’t bothered our pet or us. I would never use anything else! Demon!!

Best out on the market. The only thing is the white film it leaves behind. But that is fine as long as it keeps the place virtually bug free.
