Haha nice dude, always good to have a giant ladder! Especially one of those painting ladders lol.
These bats and small animals man, they figure out the smallest little gaps for them to squeeze in! It's crazy. Hopefully you did enough and they haven't come back and won't come back again!
Also great to spend a few extra minutes to fix/clean something you see when you're up there. Might as well give the gutters a quick clean!
