i recently used this around the perimeter of the outside of my house. by the next day, i noticed that there were dead bugs all on my front porch and along my fence where the product was placed. i live in the woods so it's very important to me that bug sprays work or they will get into my house. the spray also lasts for quite a while i used it a little over a month ago and i am just now noticing that i need to use it again. great product!
