The most common species of birds found in attics are pigeons, barn swallows, European starlings, house finches, and house sparrows. In most cases, the birds get into the attic from openings along the roof line, soffits, attic vents, or damaged sidings. In addition to attics, we commonly see birds roosting in chimneys, vents, and exhaust pipes.

When dealing with birds, it is important to understand many federal, state, and local wildlife protection laws protect most bird species. It is not recommended for at home DIY when dealing with birds in risk of going against the laws protecting most species. European Starlings, Pigeons, and House sparrows are the only birds not protected by the Migratory Bird Act.

Bird Control Services for Birds in the Attic

Depending on the species and location of nests, bird control services vary and can include visual and auditory deterrents or anti-roosting devices such as bird slides. 

The most effective methods of bird removal from the attic, chimneys, and vents are one-way doors, traps, and exclusion methods (sealing the home and blocking any potential entry points) Once this method has been executed, a trained pest control specialist can also remediate and sanitize the space where the birds occupied. Birds, like all wild animals, can easily spread and carry disease, so if a bird is in your home it’s important to not only safely remove the animal(s) but sanitize the space as well for the safety of the occupants. 

In some situations, other methods of removal and prevention work for birds in the attic. These can include habitat modification to nearby roofs and trees, various architecture exclusion, repellents, spikes, mylar tape, and scare tactics for persistent birds or large flocks.

Barn swallows are small, sleek birds known for their distinctive long, pointed wings and deeply forked tails. They have a glossy blue-black plumage on their backs and a creamy white underside with rusty-colored throat and forehead patches. These agile birds are skilled fliers, often seen darting through the air catching insects on the wing.

In Greenville, SC, barn swallows can sometimes cause problems, particularly when they choose to nest in or around buildings, bridges, or other man-made structures. This horse farm right outside Greenville, SC had several barn swallows nesting in the riding ring. The accumulation of droppings had become dangerous to the horses and created a bad smell.

Bird Netting Barn Swallow Control

Critter Control of Greenville used bird netting to remove barn swallows’ access to the rafters. Bird netting is an efficient method for managing barn swallow populations and preventing them from nesting in unwanted areas while minimizing harm to the birds themselves.

Problems from Barn Swallow

Mess and Noise: Barn swallows build their nests out of mud, which they often affix to vertical surfaces like the undersides of eaves, bridges, or the insides of barns and sheds. The accumulation of mud and bird droppings can create unsightly messes and unpleasant odors. Additionally, the birds can be quite vocal, especially during the breeding season, which may be disruptive in urban or residential areas.

Structural Damage: The acidic nature of barn swallow droppings can potentially corrode and damage building materials over time. Their nests can also clog drainage systems and cause water damage.

Health Concerns: Accumulated bird droppings can harbor bacteria, fungi, and parasites, posing health risks to humans, especially if the droppings are in areas where people frequent or where food is prepared or consumed.

Legal Issues: In some cases, the presence of barn swallow nests on structures can raise legal concerns, especially if the structures are designated as historic or protected.
