Zhanmai 4-Pack Dryer Vent Grill Screens - Aluminum Bird Guards For 3" To 8" Vents

Stop birds and critters from moving into your dryer vents! These Zhanmai vent screens are simple but brilliant - just trim the flexible aluminum grid to fit your 3\ to 8\ louver vent covers (scissors work fine), slide it into place, and boom - no more nests, mice, or other unwanted visitors. The hexagonal holes are just the right size - big enough for proper airflow but small enough to keep pests out. Made from rust-proof aluminum alloy that holds up great outdoors. You get 4 screens in the pack, and they're super easy to remove for cleaning every few months. Works for dryer vents, bathroom exhausts, pretty much any louvered vent cover around your house. Such an easy fix for a surprisingly common problem!
