This seems like good advice.
If bats are roosting outside of your house in a place you'd rather they didn't, then a can of dog/cat repellent is a good thing to pick up. Wait to apply the repellent to the area until all of the bats are out feeding, and spray all of the immediate surfaces generously. Whatever you do, don't spray the bats directly with the repellent. You're better off attending the Running of the Bulls wearing nothing but red--and that should be left to very macho but very stupid young Spaniards.Anyone try this? I'd rather not call an exterminator who will probably kill it.
