3/4" standard mesh bird netting seals off all structural openings and other possible roosting sites.

The netting is great stuff and is best when you have 2 people setting up the net. I use this to protect my chickens in there pen and have seen this stuff deflect birds of pray. Very strong netting, during a storm a 1.5 inch in diameter and about 8ft long limb fell on the netting, no problem! Very much worth the price I paid, will be buying more when the second batch of chicks come in.
