Do birds nest in dryer vents?

Yes. A dryer vent hood is sheltered and warm, and a flap held open by lint gives birds an easy way in. Nests also show up in bathroom and kitchen exhaust vents. Watch for twigs at the hood, chirping near the laundry room and a sudden jump in drying time.

How do I stop birds from nesting in my vents?

Fit hoods with backdraft dampers that close fully when the appliance is off, keep lint from propping flaps open, and check the hoods every few months. Don't add a mesh screen to a dryer vent; it clogs with lint, and Virginia code bans screens at dryer terminations.

How do I get rid of birds in my vents?

First identify the species. Federal law protects native migratory birds, so leave active nests of native species alone and contact the U.S. Fish and Wildlife Service or a licensed wildlife professional. Nests of nonnative species such as house sparrows can be cleared, then clean the vent and replace the hood.

Is a bird nest in a dryer vent a fire hazard?

Yes. Twigs, grass and lint are all combustible, and a nest blocks the hot exhaust from leaving the house, so the dryer runs hotter and lint builds up faster behind it. The U.S. Fire Administration lists failure to clean as the leading factor in home dryer fires. Stop using the dryer until the vent is cleared.

Bird Nest Removal From Vents, Dulles VA

Q: Is dryer lint safe for bird nests?

It's better not to offer it. Lint soaks up water and falls apart when wet, and it can carry detergent and fabric softener residue. Leaving lint near the vent also draws birds to nest in it. Offer twigs, dry grass or leaves instead, away from the house.

Why Birds Pick Your Vents

The hood gives shelter from rain and predators
Warm exhaust makes the cavity comfortable in cool weather
A flap held open by lint, or missing entirely, leaves the door open
Loose lint at the opening doubles as nesting material

Signs: chirping or scratching near the laundry room or bathroom, twigs and grass at the hood, and a dryer that suddenly takes much longer to dry. For a guided check, use the pests section of the problem checker.

Check the Species Before You Touch a Nest

The Migratory Bird Treaty Act prohibits the take of protected migratory bird species without prior authorization, according to the U.S. Fish and Wildlife Service. A 2004 amendment limits it to species native to the United States, and the Service published an updated list of nonnative, human-introduced species the act doesn't cover in 2020.

What to do based on what's in the vent
Situation	Next step
Nonnative species, such as house sparrows or European starlings	Removal isn't restricted by the act; clear the nest and fix the hood
Native species with eggs or chicks	Leave it and contact the U.S. Fish and Wildlife Service or a licensed wildlife professional
Species unknown	Photograph the bird and nest, then get it identified before removal
Old nest, no birds seen for weeks	Confirm it's empty, then clear and clean the vent

How a Nest Comes Out of a Vent

Stop the Appliance
Don't run the dryer or fan while the vent is blocked.
Open the Hood
Remove the outdoor cover to reach the nest.
Pull the Nest and Loose Debris
Wear gloves, and bag the material.
Clean the Full Line
Nesting material and lint travel deep into the duct; brush and vacuum it end to end.
Replace the Hood
Fit a hood whose damper closes fully when the appliance is off.

Keeping Birds Out Without a Screen

A screen over a dryer vent clogs with lint, and Section M1502 of the Virginia Residential Code bans screens at dryer terminations. Use a hood with a backdraft damper that closes on its own, keep lint from propping it open, and check it every few months. The dryer vent inspection page shows what a passing hood looks like.

Bird Guard Installation: Where a Guard Fits

A bird guard is a metal mesh or louvered cover that stops nesting birds for good. On bathroom and kitchen exhaust caps a guard is a sound permanent fix: those ducts carry only air and moisture, so mesh cannot choke them. Install a guard outside the nesting season, after the cap is clear and dry, and screw it to the cap rather than gluing it, so the next cleaning can remove it.

Dryer vents are the exception, and it is a code exception. The same residential code section that caps vent length bans screens at dryer terminations, because lint packs a mesh guard within a season and blocks the exhaust. A dryer vent gets a hood with a backdraft damper, never a guard. If birds keep targeting a dryer cap, the fix is the damper hood plus the cleaning schedule above.

Is Dryer Lint Safe for Bird Nests?

Skip it. Lint soaks up water and falls apart in rain, and it carries residue from detergent and fabric softener. Leaving lint around the dryer hood also invites birds to build right there. If you want to help nesting birds, offer twigs, dry grass or leaves away from the house, and keep the vent itself lint-free with regular dryer vent cleaning.

Timing and Cost of Nest Removal

Nest removal is billed as part of a vent cleaning, since the lint and nesting material come out together and the line has to be cleared end to end either way. The variable is timing, not price.

What changes the job
Situation	What happens
Nest of a nonnative species	Removed and the vent cleaned on the same visit
Active nest of a protected species	Work waits until the nest is no longer active
Empty nest, any species	Removed during cleaning
Hood damper broken or missing	Replaced so the birds can't return

A dryer vent cleaning around Dulles runs $135 to $360, and the hood replacement is what stops next spring's nest. Skip that part and you pay for the same visit again.
