Geeee Wayne....why didn't I think of that......DUH....I've been doing that for 25 years....I even had an enclosed gutter system installed....I've gone through a new roof....I've shot them as they emerged from my house, I've shot them(head shot) as they peek out of my gutters(prior to the new) I simply kill every one I see....still doesn't work....I received flying squirrels a few years back....as they are nocturnal, I have no recourse for them...I would be willing to bet, that if you removed EVERY squirrel within a one square mile area around my house, I'd have them back in my attic within a month...I had to start using a noise machine to cover their noise...I would have to say, that in the past 10 years(maybe more)...I've killed way over 100....probably closer to 200...My daily record is 5...the photo, with 2 in it....that's the exact way they fell.....shot 1, then a few minuets later another climbed up the same tree, on the same limb....blamo!!! I killed 4 that day...
sorry for the sarcasm...sometimes I get a little testy on this matter
