I've had a problem with a squirrel living in the attic of a warehouse I work in. He had chewed holes in the wooden soffit to get into the attic and would chew a new hole everytime the building owner would plug his entry.
2 weeks ago I trapped him and drove him nearly 2 miles away straight down a country highway and let him out. As of today, either he has found his way back or another has taken its place.
Could that squirrel have possibly found his way back to the building? Are they able to do that like some dogs and cats.
If so, I'll have to trap him and take him much further away, on the other side of the river.
I don't know if he would have come all the way back, but I think squirrels are pretty opportunistic... even if you take this one across the river, probably another will take it's place. Can the owner use some sort of metal siding to cover the hole up instead of wood?
Eventually I should talk to the owner of the building any maybe he will take some kind of measure to keep them out for good. It is a metal building except for the soffit area around the front but it's wood shakes all around the sides and the underside is thin plywood so that is a lot of area to try to cover with metal and still keep somewhat attractive.
The squirrels have made a mess of the ceiling by knocking down a lot of the insulation stuffed between the rafters. It's not an actual ceiling but made up of paper and foil backed roll insulation tacked to the rafters. I'm constantly on the ladder taking the insulation back up.
