calimaero® 2 Pack Bird Stop Dryer Vent Grill Screen Guard Insert 8.8in x 8.8in Customizable 3inch to 8inch Stops Nesting in Bathroom Exhaust Vents

Used less than two weeks on my dryer vent and it was clogged up. So glad I checked before it started a fire. Wasted my money.Good luck.

Great product to work with. We used it to block a vent opening from birds building nests. Was able to cut easily and form to the areas we needed to fill. Then use gutter sealant to attach to vents. Worked perfectly. 100% awesome. Cut with aviation snips and bent easily. It is very bendable though so more or less better to be used as a screen type product.

Liked how easy to use and effective

Easy to cut and is sturdy.
