Definitely recommend!

I was pleasantly surprised by how well this works! This summer everyone, including us was having problems with ants, I sprayed one time with this and that's all it took. I have inside dogs and it did not affect them at all, following the directions on bottle about pets. It worked so well I went ahead and treated the entire inside and outside perimeters and have not had any problems with anything. Definitely recommend!
