It is not illegal to trap squirrels. I could just kill them if I wished, but my sensitive nature
makes me re-locate them instead. Heck, our Animal Control Center will even lend traps for this purpose. Squirrels, though fun to watch, are no different than coons, armadillos, skunks, possums, and on and on. When they cause damage, that's all that's necessary to trap them.
