Try using soap to repel squirrels, deer and other critters from your garden! Grating soap around plants they love, or hanging bars of soap around your garden perimeter might help keep them away! Have you tried it?
This one really works! every year i go through a few bars that i grind a hole into and hang around. @pixiedust personally i never saw anythng happen to the plants but I think its better to hang them than to shred that soap up everywhere
