Moth balls or red pepper won't be practical in this scenario. Unfortunately they have to be removed. They know I'm watching them... up to this point that's all I have been doing.

I had an issue with squirrels when we first moved to this place, back in the early 2000's.., me wife used to feed them, and over time we became seriously overrun by them. The last straw was when one got up under my F350's hood and ate the engine's wiring harness. $950,00 to replace. Started taking them out with my pellet gun... got about 10 of them before I became tired of shooting them... then started trapping them... and relocated about 12 more... got the residual numbers down to a much more acceptable level.

I don't particularly enjoy killing any type of animal just for the hell of it... there has to be a bonafide reason for doing so. I still deer hunt, and used to fish... for food.
