I was mulling over the idea of placing a 24" x 24" (or so) 1/4" treated plywood under the hive a bit and extending out well past the entrance.
To deter skunks and racoons, what of the idea of imbedding sharp nails, staples, screws, etc from the underside. This would cause pain and injury to anything attempting to approach the bee entrance.
It would also keep the entrance area free of weed growth.
Has this been tried????
