The larvae in those wasp nests make the best bream bait you can get. My Uncle Bill used to leave a few of these nests up under the eaves of his barn, and knock some down to carry with him for fishing.
He was from lower Alabama. He was described as a "turrible fisherman," which, given the penchant for understatement in the local dialect, meant you could just about count on him to catch his limit.
