Its better than mice. When i had my avenger in freshie year of college my rents didn't lemme take it to school so it sat in the driveway forever. While it was chilling some mice decided to burrow into my car and make a little mouse nest in my vent. So then my A/C started to work funny and my car smelled, so we took it into the shop and they had it for quite a few days trying to find out wtf was wrong....yeap. Then it literally smelled like shit when you would turn on the A/C after that.

Spiders dont' do any harm, so its all good. Hhee.
