What is the proper treatment location for carpenter bees?

The proper treatment location for carpenter bees is at all gallery openings. Carpenter bees are known for their nesting habits, which involve drilling into wood to create galleries for laying eggs. These galleries can be found in wood structures like eaves, decks, fences, and more. Treating all gallery openings ensures that you target both active nests and potential new infestations. This approach is essential for effective pest control and prevention, as it addresses the areas where the bees are most likely to enter and exit their nests.

By treating only specific locations, such as the interior of walls, adjacent to windows, or solely nests on trees, the treatment may miss critical entry points or existing nests, allowing the carpenter bee population to persist or re-establish. Therefore, focusing treatment on all gallery openings provides a comprehensive strategy for managing carpenter bee populations effectively.
