You don't have a cat? The shelters are full of guys who would love to help you out...any rodent smaller than a capybara would be dead or banished within an hour.
I think cats are cute and hilarious, but unfortunately I'm highly allergic.
The store didn't have any ethic traps so I ended up getting some d-Con bait pellets (poison) and some Victor Sonic PestChaser devices (apparently they emit some high frequency sound that drives rodents nuts). Sounds like the kind of plan that will fail, but we'll see.
I also replaced my garage door seal, which was chewed up and was the entry point the rodents were using.
