My mother used to put moth balls out to keep the squirrels away from some of her plants. As she watched, the crows would come down and picking up the balls rub them all over themselves - taking time to reach every feather. They did it to rid themselves of mites….how they knew that would work is beyond me but they did it every time she put new moth balls out in the garden.
