What do Greater Wax Moths primarily damage in a beehive?

Greater Wax Moths are known for their ability to inflict significant damage to the comb structure within a beehive. They primarily target the wax comb, which serves as the foundational element for bees to store honey, pollen, and raise brood. As the moth larvae feed on the wax, they create silken tunnels, effectively destroying the organizational structure that bees rely on for a healthy colony.

This damage can lead to several issues, including a breakdown in the hive’s ability to store food, difficulties in brood rearing, and an overall decline in the colony's health. The moths can proliferate rapidly, especially in weakened or non-maintained hives, making understanding their impact crucial for beekeepers in order to take preventive actions.
