>They are territorial. You're not kidding. When I bought my house it had sat empty for a couple of years and a family of raccoons had added it to their territory. Closing up vents helped, but once a year or so they'd return and try again. I'm just guessing but I think the mothers would still try to work the metal grating out of the vents when they were pregnant. I didn't really want to kill them and frankly trapping them seemed like a lot of work, plus they had fleas and potentially carry rabies, not to mention possibly having a parasite in their feces. I didn't want to hurt them and I didn't really want to get near them. As with most anything else you can buy the solution on the internet: puma pee. A liberal sprinkling of the foul smelling stuff ran off me, my wife and the raccoons. We can't smell it any more but apparently the raccoons can because they haven't returned.
