We have small hive beetles here in upstate New York. Some threads that I have read dismiss small hive beetles as a nuisance that a healthy hive can handle. Maybe so but I wish beekeepers and Betterbee and the like took more efforts to control them When making a split or adding new boxes or in early Spring the larvae from small hive beetles can putrify and destroy a hive. if you have ever seen the larvae in great numbers on the bottom board you would know how disgusting they are.
OK what do I have to offer you say. Rather than just trapping adults which isn"t a bad idea or using pesticide I have really good long term solution. I have been placing trays under the hive entrances on the ground so that when the larvae exit the hive to pupate in the ground they end up in my pan. They started producing larvae in April here since they seem to make it through the winter. Over time there shouldn't be any more beetles except new visitors from unknown sources nearby. Hope this idea catches on.
