Bat highway

In all my years of bat work, I've never seen this type of wear from bats. I've seen shingles with the pebbles worn off, but they have actually worn THROUGH the shingles at this home. Right through the fibrous material. That takes a "few" trips!

Wow ! ...that is a lot of trips

Looks like one of those multiple device situations to allow for easier exclusion. As you know they don't like to stand in line to get out at nite.

I've never seen anything like that either. That's pretty impressive. How deep is the guano inside or are they just in the soffit?
