Im working on my 3rd treatment, as its been about 6 weeks. I will say that I am treating two areas simultaneously, my boyfriends apartment and my room at my families. The good news is that there seems to be plenty to go around, and for multiple continuous treatments for my place and his. Downside is that it doesn't seem to be working; I cannot get any relief from these pests. My skin reacts horribly to the bites and there is swelling involved. At one point there were bites above one of my eyes and it had swollen ( think hunch back of Notre Dome). Or heres something I haven't read in any reviews ( and I've read a lot of them) the breakfast, lunch and dinner bites appearing on my tongue, yeah I sleep with my mouth open. I am definitely at my wits end. And Im losing so much sleep over this and I don't even have an infestation. I've been at my place for 16 years, and this year is the first time I've ever had a problem like this. My next move is to purchase the mattress and box spring covers and apply treatment to both vehicles. I will update later but as of right now I am NOT happy.
