NO moth balls please . They are highly toxic. You might have unintended consequences.Gramma what about using fox urine or hanging some mothballs around the corn to keep foxes out?
Pharm. your not the only who's missed the solar switch took me three days get my butterfly to work.
Fox urine would attract foxes wouldn't it? Don't know have never used it.
There is Coyote urine too, but again I'd be afraid of attracting Coyotes.
Now if you're not too near neighbors how about a motion activated radio set for a Rap music station. If you have a spot light near. You could put a bulb in one side and the cord to the radio in the other.
