How Do I Get Rid of Birds in My Attic?

Posted by: Cooper Pest

You may be surprised to know that bird nesting is a common problem for homeowners in New Jersey and Pennsylvania. Once outdoor temperatures begin to warm up with the change from winter to spring, starlings and sparrows begin building nests to lay eggs. European starlings and house sparrows are social birds that prefer to live in flocks within natural habitats and humanmade spaces like attics. If you’ve ever experienced a bird infestation, you know how serious and frustrating it can be. Excessive droppings, physical damage, and noise only increase throughout the season if the problem isn’t taken care of. Did you know birds will return to the same spots year after year if they have access? If there’s nothing to stop them from nesting, why would they go elsewhere?


How do you know if you have birds in your attic?

Birds nest within soffits, gable vents, broken vent covers for exhaust fans, stove vents, bathroom vents, dryer vents, exposed gutters, and light fixtures by entrance ways. Once they get indoors, they aren’t especially stealthy. Excessive flapping, banging, or scratching noises in your attic could be caused by birds. They are most active in the early morning and evening, but that doesn’t mean you won’t hear them at other times of the day. Birds poop everywhere which is the first telltale sign that birds are roosting in your attic. When you enter your attic, you’ll be hit with an unmistakable stench which is a dead giveaway. Bird droppings accumulate very quickly, mainly because they live in large flocks.

If you see the birds, they may be starlings or sparrows.

European Starlings can be identified by their black feathers with a greenish blue iridescence that’s covered in white spots, and having a pointed yellow bill. They are relatively small birds that are 7.9-9.1 inches long with a 12.2-15.8 inch wingspan. They are arguably the most common nuisance bird in New Jersey and Eastern Pennsylvania. The massive groups of noisy black birds on your lawn are probably European starlings. We’ve all encountered them outdoors, but they are a significant problem when they nest in attics.

House sparrows are very small birds with unique coloring. Females have black and brown striped backs with a grayish-brown body. Males are very similar with the exception of darker reddish brown coloring on its head and dark brown mixed in with the black stripes on its back. These non-native birds are abundant in New Jersey and Eastern Pennsylvania, as well as across the entire country. Much like European starlings, house sparrows gather in large groups and feed on lawns and around your property. They also prefer nesting in light fixtures, gutters, and attics.


What are the health risks of birds nesting in your attic?

Birds are very messy animals. Their poop can quickly accumulate, causing a health hazard. Bird droppings can transmit various pathogens, parasites, and bacteria, with the risk increasing as the bird problem goes unaddressed. If you’re waiting until the birds leave on their own, you’re out of luck. Some types of local birds come back to the same place year after year if they can. When they find an insulated, dry space that protects their nests from predators and rain, there is no reason for them to leave.

Birds will make their nests out of both natural and manufactured materials. On a quest for nesting materials, birds can tear through wiring in your attic which is an immediate fire hazard. They can also rip up attic insulation and paper stored in your attic. Fallen hair and string are also favorite items for bird nesting. In addition to destroying your personal items, birds also bring outdoor nesting materials indoors. That means leaves, feathers, grass, and other vegetation will be stockpiled around your attic.

Top Bird Prevention & Removal Tips for Homeowners

As a homeowner, you’re probably wondering what you can do on your own to prevent and get rid of birds in your attic. It’s a good idea to do this before bird nesting season begins to prevent the problem before it happens. The most effective way to handle bird infestations is to ensure that all potential entry points are sealed. Inspect your attic for broken or torn vents, small holes that lead outdoors, or any other possible entry points. By using a flashlight, you can more easily find openings that allow you to see outside. If you find any of these problems, repair and replace where possible. Walk around the exterior of your home and look for holes around gutter lines, up under soffits, and additional torn or old vents.

Bird feeders and birdbaths are troublesome for several reasons. Not only will it encourage birds to spend extended time on your property, but it can also attract other undesirable critters. Mice, rats, squirrels, and other local wildlife are drawn to fallen birdseed on your yard. Birds are messy eaters, leaving a large amount of their meal on the ground. Squirrels are another notorious pest that loves bird feeders. You’ve probably seen bird feeders in your local retailer or garden center that have springs built in to avoid squirrels. While this may provide some relief, it’s never guaranteed that squirrels won’t be crafty enough to snag a free meal. Bird baths are a problem for spring and summer pests. Did you know mosquitoes can breed in water as small as a filled bottle cap? Mosquitoes lay eggs on stagnant water such as bird baths, water gathered on playsets, or in open buckets for example. To avoid mosquito breeding on your property, it’s advised that you empty bird baths regularly.

You also need to be careful if you find eggs or chicks in your attic. Sealing them in prevents their mother from bringing in food, which will result in death. They can also be forced into additional parts of your home once they are able to move on their own as they search for a way to leave the house. If you find live birds in your attic, call Cooper Pest Solutions for professional removal and sealing services.
