When you purchase a birdhouse, the intent is for birds to visit while you enjoy their beauty. The intent isn't to create a habitat for wasps. However, too often that's the case. Paper wasps are especially fond of taking over birdhouses. Naturally, birds are scared off by their presence and don't return for a while - if at all. Consider these tips to keep wasps out of your birdhouse.
Wasps like to build intricate nests, and the ones in bird houses are no exception, the Knoxville News Sentinel noted. These pests build nests that have multiple compartments and are shaped like an umbrella. The nests are suspended by a small stalk in the middle. Wasps like to build their nests in the spring, right around the time that birds go house shopping before laying their eggs. If birds already laid their eggs and wasps choose to build a nest, birds may abandon their young before they hatch. Paper wasps are the biggest culprits for these nests. They're called paper wasps because their nests resemble something created out of paper mache. The nests are actually made of saliva and small plant and wood fibers.
These are just a few pest control tips to keep wasps out of your birdhouse and your birds at peace.
