Swallows are migratory birds that become territorial. Their mud nests which they establish under eaves and in corners of structures can cause staining and damage to structures. Corrosive feces, which can contain bacteria and disease, typically smears the sides of buildings by their nests. Before a swallow infestation becomes uncontrollable, it is important to have a plan.
Barn Swallows forage in open areas throughout most of the continent, including suburban parks and ball fields, agricultural fields, beaches, and over open water such as lakes, ponds and coastal waters. They range from sea level up to 10,000 feet. Breeding habitat must include open areas for foraging, structures or cliffs to build nests on, and a source of mud such as a riverbank to provide the material for building nests.
Swallow Life Cycle
Barn swallows form breeding pairs in the spring, when they return to their breeding grounds. Barn swallows often mate in the air. Both parents build the nest. The female lays four to six eggs. Both parents incubate the eggs and care for the chicks. The eggs take around two weeks to hatch and the chicks fledge when they are about three weeks old. The parents continue to feed the chicks for up to a week after they fledge. The female may have two broods a year. The same pair may mate for several years.
Remove old barn swallows’ nests once they are vacant are. Thoroughly clean all feathers and droppings with a cleaning solution. Add a coat of fresh paint over areas to be treated smooth surfaces make it harder for swallows to attach nests to. Remove all old nests from unwanted surfaces so they cannot be reused.
