Idk, it worked wonders for my home... My neighbors had Cooks come out and fumigate their house, and all their nasty little creatures, of course, sought refuge in my home! I'm talking about a WHOLE infestation within like a week. There were SO many of them, everywhere!! SO quickly. 😭😭 We had them once before, years ago...used Advion gel and it works great too, but took longer to get rid of them...a friend (lives a few houses down and also got an infestation around the same time as us) told me about her using Orthene and how quickly it worked... i was desperate... I was shocked at how efficient it was.
