kill em all, squirrels are way to thick and fun to hunt. if you do kill what you think is all of them. come back in a month and be prepared to see alot more squirrels. if there are alot of squirrels at a "hot spot" they are there for a reason. be assured that the next squirrels that move through the area will stop at this spot for the cover, food, water, or combination of all three. i know of a sycamore tree that has to be 100 years old. one afternoon i set there deer hunting and watched 16 diferent squirrels climb into the same hole for nesting that night. i cant wait to go bust em up one afternoon.
