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!!

Best bug spray ever
This is all I need for keeping those pests outside. One envelope equals a gallon and I spray it all around my house outside and then inside I put it where my window seals are. No bugs in my house as they don't pay rent. Great quality easy application and it is effective.

Works fast and lasts
This is going to kill all the bugs in your house. I don't usually see many insects in my house, but the first time used this I started seeing dead insects all over the place. It lasts a long time, and I can't imagine using anything else for routine pest control. The only downside is you have to make a minimum of one gallon at a time and you cannot store the leftover prepared mix for more than a day or two before it loses its effectiveness.

Wow!
No odor. Kills just about anything you want dead. Had ants in the wall. Found where they were getting in and sprayed all around. Next day, dead ants everywhere. More the next day and the next. Dead ants inside too. I am keeping this on hand now.

Great Insecticide
This product is amazing! I've used it for years. It's great insecticide protection. I live in the country and this protection is really needed. Works for us for months before we reapply. We reapply on a regular basis before issues arrive. It does leave a white residue. I've noticed after some time it becomes much lighter. Great value. I use a multi purpose lawn and garden sprayer to apply inside and outside. I use gloves, a mask and protective clothing then place packet inside sprayer and then add water according to directions, its easy to mix. Need to use the mixed insecticide within 24 hrs. I've found it does have an order. Please be sure to follow directions and instructions for safety.

Did What It Was Supposed To ... Love It!
I Wore Long Sleeves & Long Rubber Gloves But Still Ended Up With Burns & Irritation On My Arms From Litter Droplets That Got On My Sleeves But It Was Worth It! The Product Did Leave A Off White Cast Where Applied, So Keep That In Mind But The Way It Killed Everything Seemingly Instantly & I Haven’t Seen Any Live Creepy Crawlers Since I Sprayed Months Ago. It’s Well Worth The Buy!
