Peanut, when I lived in south La., when ever we had a crawfish, crab,shrimp boil of course with lot's of Tabasco mash from the island .you could buy it in ziploc bags. My father in law would say after we ate,heat the water back up to a boil,grab some shovels , now in LA. the mounds were about 12 ' high, and very similar to a bee hive(queen, workers, drones,virgin queens)
As y'all did in a way, we'd turn the mound,full shovel in the ground and throw that around the sides and pour the boiling pepper water in a 12' deep hole. Now it will kill grass around it.
