Which formulation is used for carpenter bees?

• A. Dust
• B. Liquid
• C. Foam
• D. Gel

Answer: (A)

Carpenter bees spend most of their life inside wood galleries, so the treatment must reach deep into those voids. Dust formulations are ideal because they can be blown or brushed directly into the entrance holes and tunnels, coating the bees and interior surfaces as they move through the galleries. The fine powder stays in the voids, providing both contact kill and a residual effect that can endure over time, even if weather or cleaning would wash away liquids. Liquid, foam, or gel products often don’t reach deep into narrow, irregular tunnels and can run off or fail to stay in place where the bees are most active, making them less effective for this pest. That combination of deep reach, persistence, and minimal runoff makes dust the best choice for carpenter bees.
