Solving the squirrel on the roof problem
There is an interesting discussion over at rec.guns about the best way to deal with a squirrel chewing on the roof. It is worth a read.

“Pumper Hinkle” sums up the options:
Hmmm. I understand your problem better now. For the squirrel to be
chewing on your roof, though, he must be sitting still for at least a
little bit.I believe that if it were happening to me, I’d get a night vision scope for
the bolt-action .22 and sight it in using BB caps. I’d then set up a
sniper position and be patient. Once it stands still, bang.Or, well, you could get a .410 shotgun and some light loads, and figguring
on patching the roof maybe.Or, I believe you can fire .45 colt cartridges in a .410 shotgun, and I
believe you can get .45 snake loads.As you’ve observed, the .22 snakeloads don’t cycle in autos, and the rifling
disperses the shot too much. I believe I once heard of a smoothbore .22,
which would give better range.But I assume you don’t want to buy another gun, especially some sort of
specialty gun. So, back to first suggestion, night vision scope on the
.22.
Or he could just use a pump .177 air rifle. Quiet and effective!
Why not just get an air rifle or even use a live trap?
Why on earth would you use a nightvision scope when squirrels are not nocturnal? A standard scope, or iron sights are perfectly fine.
Use a suppressed .22, or a high-velocity .177 (which is a LOT louder than a suppressed .22). Forget using shot- you’ll end up tearing up the roof as much as you would the squirrel.
I got 9 squirrels in 2.5 weeks with a piece of 4 in PVC pipe, a bucket of water, and some peanut butter.

Disposing of the bodies will be your next concern. Hail Offler!

The run-up to this arrangement is too evil and demented for words, and also required too much tending, but involved launching squirrels from an air cannon. Fun, but impractical.
If they’re chewing the roof, they’re probably hungry.
Squirrels and pidgons are real pest, they damage homes and commercial property.
I have been using my .177 air rifle (1000FTPerSEC). It kill the critters but does not damage my roof or siding.
I guess if I missed them it would dent the roof tiles or the siding.
It works fine on feral cats, raccons and dogs. One shot=one kill.
It works for me. Fuzzy
