A couple of weeks back we had some birds move into the walls of the house.
See, we've got two dormers on the front of the house and just under the eave overhang on each side of the dormers where the dormer meets the main roof (so four places), the builder didn't actually finish the siding... so there were four places wide open for small creatures to move in. Apparently this is very common, at least in this area.
Anyway, I was working in one of the rooms upstairs and I heard this scratching noise. Going outside and looking up, I could see all sorts of nest-makings coming down the roof out of the hole in the siding.
I ended up having to call a guy and he came in, got all the bird stuff out of the walls, and blocked up all the holes with metal screen. I'd have done it myself, but our roof has a really steep pitch and, frankly, I am not a handy person and have no idea what I'm doing. I'll pay someone else to risk their neck and do it right any day of the week.
If you ever get in that situation and you're in the Portland, OR area, well... first, I'm sorry, because that sucks. Second, the guy I called was Ed Belding from Evergreen Pest Management - (503) 925-9752. Great service, reasonable prices, and he does more than just birds. Give him a call, he'll hook you up.
Now to address the bathtub that's started a spiderweb crack upstairs...
