Working on a job where I kicked them out last yr but they insist in hanging around the house. Any preference on size of wire 1/4 vs 1/2 inch stuff to screen off the roost area ? Thanks

Sorry Adam I read your question wrong. You are trying to make an exterior roost area unusable.
I'd agree with Jim you need a smooth surface, plexi, metal, painted up and affixed versus something they can cling to
and grasp like wire.

I have jobs where they are still coming around to night roost during feeding but the clients don't have
issues with this as long as they aren't in the house. Other clients only have night roosting and want them gone.

Sorry for the confusion on my other response.

Again, just my .02,

Justin

I am not an expert eather. However, I think the bats will just hang from the wire. I would use metal.
