Wasps in birdhouses
Can you tell me how to keep wasps from building their nests in my birdhouses? We have a real problem with that here in Fort Collins, CO.

I plug the entry ways to my birdhouses with paper towels or fabric to prevent anything from nesting in them until the birds are ready to move in. If the houses are already infested with wasps, Sevin dust will kill them. Just be sure to scrub down the houses after the entire colony is killed, and before the birds build their nests in them.
