As Taylor indicated above, often there is only 1 tick. They do not multiply like fleas.
Pest control around or in the home generally isn't that helpful. Pesticides used on lawns and in gardens probably have the most impact. Most of our ticks here fall out of trees onto us. I was working in our yard once and came inside, bent over to pet Teddy, and a tick fell off my head and onto Teddy. I was able to get the tick off of him quickly.
Teddy is a magnet for ticks. He must have the right scent because the bugs always go to him and leave Max alone.
