A dryer or bath fan vent is a warm, sheltered opening, which makes it a favorite nesting spot for birds and an easy way in for mice. This Deflecto Universal Bird Guard installs over most existing 3 in bathroom exhaust vents and 4 in clothes dryer vents to help keep them out. The one-piece white plastic guard has a UV inhibitor against sun damage, and it comes off when it is time to clean the vent behind it.
Key Features
- Universal fit: installs over most 3 in bathroom exhaust vents and 4 in clothes dryer vents.
- Keeps pests out: helps prevent birds from nesting in the vent and rodents from slipping inside.
- Self-cleaning design: wind and rain help clear the guard between checks.
- UV-protected plastic: an added UV inhibitor helps prevent sun damage and cracking.
- Removable for cleaning: take it off to reach the vent hood and duct.
- Quick install: goes over your existing vent with no need to replace it.
What's Included
In the box: one white Deflecto Universal Bird Guard for a 3 in bath exhaust vent or a 4 in dryer vent.
Before You Buy
- Measure your vent before you order. It fits most 3 in bathroom exhaust and 4 in dryer vents. Larger vents need a different guard.
- It covers an existing vent. The guard goes over the vent already on your wall. It does not replace a broken vent hood.
- Check it for lint often. Dryer lint and debris can collect on the guard. Look it over regularly and clear it to keep air flowing.
Perfect For
- Dryer vents where birds keep building nests
- Bath fan vents that let mice or other pests inside
- Spring nesting season prep
- New homeowners sealing up the exterior
- Rental properties that need a low-cost pest fix
Care & Use
- Check the guard for lint and debris frequently, especially on a dryer vent.
- Remove the guard to clean the vent hood and duct behind it.
- Wipe the plastic with a damp cloth to remove dirt.
- Clean the dryer lint screen before every load to cut down on lint at the vent.

Built for outdoor life
Molded in one piece from weather-resistant plastic with an added UV inhibitor, the guard is made to stand up to sun, wind, and rain on the side of your home year after year.

Why choose a bird guard over other fixes?
vs. a hardware cloth patch
Cut mesh takes measuring, cutting, and fastening. This guard is molded to fit over the vent and lifts off for cleaning.
vs. replacing the whole vent
A new vent hood means tearing out the old one. The guard goes over the vent you already have.
vs. leaving the vent open
An open vent invites nests that can choke off the exhaust. A guard helps keep the opening clear.
Fits your exterior vent
Sized to cover a standard dryer or bath fan vent on an outside wall.
- Guard
- about 7 1/4 in wide x 4 1/2 in deep
- Vent sizes
- 4 in dryer or 3 in bath exhaust
- Goes over most vent styles on siding or brick walls.
- Leave room around the vent so you can lift the guard off for cleaning.
