You’ve got a raccoon in your walls. As cute as these little bandits are, their urine and fecal matter are on a whole different level. Breathing that in on a regular basis can lead to a slew of respiratory issues/infections. Once it has been removed It’s important to seal that area in killz primer or other similar type product.
I once had a family of raccoons living in the walls of my house. The cleanup required removing all the floors in the hot and a hazmat team had to come in and remove the soil and spray some kind of disinfectant around the whole house. Raccoons are nasty little creatures.
Their fecal matter can also give you incurable brain parasites
Raccoon:
We gotta start thinking like a raccoon here. You need another raccoon. Here’s what were going to do, I’m gonna crack a hole in your wall. Just a tiny one. It’ll be cool. Then I’ll slip the other raccoon in with a tiny string tied around it.
Magdump into the wall: Those little bastards are crafty.
There must have been other signs
