Do you live near a wooded area? We do and have those flying roaches always trying to get in... yuck! We have Terminix spray and I used to freak out the first couple months because every now and then I'd see a dead roach on my floor. Apparently when they would enter the house and cross over the spray it just took a couple feet to kill them. So, I really shouldn't have been freaking out, because the spray was actually working.
