Small hive beetle (SHB) is an exotic pest of honey and bumble bee colonies that is native to Africa. SHB feeds on pollen and honey, kills bee brood and workers, and causes honey to discolor and ferment. This pest is now found throughout much of the U.S. with highest infestations occurring in the Southeast. It was first detected in Utah in 2016 and is now confirmed in Washington and Davis counties. Infestations can be prevented by early detection, using good husbandry techniques, maintaining a high ratio of bees to comb, and keeping hives in partial to full sun. Chemical control options for SHB are limited due to toxicity to bees. Coumaphos strips placed in the bottom of the hive can reduce infestations.
