I don't have a tick issue here, but I took Behr to Tennessee to visit my dad and brother when he was 6 months old. I had him on a flea and tick program, forget which one, anyway, I didn't think anything about ticks. Until....
About a week after being back home, Behr was eat up with them, and later me and my condo were infested too. Had to have professional exterminators treat the condo for 3 months.
I learned alot about them during that time. They like to get high up and jump down on their "prey". They were all up in the corners where the ceiling meets the walls and was "black" with them over the front door.
It was crazy!
