2 part water
1 part vinegar
1/2 part hot sauce
chili powder (as much as you can spare, usually 2 tablespoons)
Mix everything together, spray around what you wish to protect (grass, plants, windows, wood piles etc.)
It works really well for squirrels, rodents, rabbits, etc.
At our house we have a storage unit positioned up against a wall outside, and all kinds or animals try to claw/chew/defecate their way inside. This spray keeps them away. Re-apply it often, as it can be washed off easily by rain or whatever.
If possible, don't deprive the animals you are displacing! If you're nixing a possible food supply for them, offer a better option for both them, and you! And if you are nixing a possible living place, do it in the summer, so the animals have ample opportunity to find shelter before winter hits.
