Google "bat exclusion" The trick is to rig screens so they can get out, but not in by attaching a square or rectangular screen on three corners so they can push it out to exit, but can't get under it to get back in. After you're sure they're all out, attach it firmly all around so they don't figure out how to slip under it the other way.You might even try making an outward-pointing cone of 1/4" mesh arounf the wiring with just a bit of space right around the wires, and leaving some pointy bits to discourage them from trying to squeeze back in through it.nedmoore wrote:I have some BG's in my house! It seems that either squirrels or god forbid- rats are coming in through the part that connects the garage to my house (where all the wiring and some plumbing, etc.) travels into the house.
If you have proper air circulation, (smells from the attic don't come into the house) make some packets of mothballs in old socks or similar to put up there; most mammals don't like the smell of mothballs.
