They are also fairly cheep probably the cheapest ammo beside stones there is, i get a 50L Bag for ~20$. That aside i honestly would go with clear paintballs on a very low powered bandset, or one of my all-time favorites are expanded clay pebbles (round) they are cheap they are totally bio-degradable and they are astonishingly accurate if there isn't too much wind or long distances involved and on impact (hard surfaces like trees) they explode into clay dust leaving nothing but an redish-black point that is gone as soon as there is rain.ĪND because they are very light they don't get that much power that even if a squirrel gets hit chances are he rather dies of an heart attack out of fear than it does because internal damage, so don't aim for the head but the tree near it! Hmm i don't know anything about a deterent per se but i could give you a recipe including smashed potatos with fried onions and a red wine sauce featuring a mixed greek salad with it
