We had ticks in the house a few years ago. We were using Advantix at the time, but the ticks still rode in on the dog's. The Advantix will kill a tick once it bites, but can reproduce in the meantime. Spoke to the vet and the first thing she said was don't wait to get rid of them since they multiply quickly. Look at the ceiling where the wall and ceiling come together. Ticks like to live there. We found them hiding out there. We ended up "bombing" the house 8 weeks in a row (yes, 8!) before they were totally gone. It was a hassle, but worth it for them not to overrun the house. We, too, had sprayed the yard several times. Vet also said if they get into the attic (which they love) it is nearly impossible to get rid of them. So, keep at it and don't let those nasty buggers win! Good luck!
