There isn’t one single “best” option—what works well depends on where the bees are active and your preference.

• Foaming aerosols: These are labeled for carpenter bees and can expand into galleries (tunnels) to reach hidden insects.
• Ready-to-use sprays: Useful for treating exterior surfaces where bees land or hover; some offer non-staining, odorless, and indoor/outdoor options.
• Traps: A chemical-free way to help reduce activity around eaves, decks, and fascia boards.

Many customers combine methods: foam for active holes, a surface spray for high-traffic areas, and traps as a monitoring tool. Always follow label directions and check that the product specifically lists carpenter bees. Finishing exposed wood can also make surfaces less attractive over time.

Target the galleries quickly and safely, then protect the area.

1. Identify active holes: Look for round openings and fresh sawdust beneath eaves, railings, or fascia.
2. Treat at low-activity times: Apply a foaming insecticide labeled for carpenter bees into the entry point as directed on the label.
3. Wait per the label: Allow the foam or spray’s stated interval to work.
4. Seal the hole: After the recommended wait, plug with wood filler and finish the surface to deter re-use.

Hanging outdoor traps near eaves can also help reduce activity. Keep people and pets away until treated areas are dry, and avoid spraying open flowers. Results can vary by infestation size and structure type.

It’s not advisable. Household lubricants aren’t labeled for pest control, and using products off-label can be unsafe and may not address the problem.

• Use labeled solutions: Choose foams, sprays, or traps specifically labeled for carpenter bees and follow all directions.
• Consider non-chemical options: Outdoor traps and sealing/finishing exposed wood can help reduce activity without using insecticides.
• Focus on the gallery: Targeting the bees’ tunnels with a labeled foam or treatment provides more directed control than household products.

Sticking with carpenter bee control products helps manage risk and improves the chance of reducing activity. If you prefer to avoid chemicals, rely on traps and structural fixes.

Broad or indiscriminate control can impact beneficial insects and your surroundings. Many customers prefer targeted approaches that focus on the bees actively drilling into wood rather than widespread spraying.

• Targeted control: Treat only active galleries with labeled products and seal holes afterward to deter re-use.
• Non-chemical support: Use outdoor traps near eaves to help reduce activity around structures.
• Prevention: Keep exposed wood painted or stained and repair weathered areas that attract nesting.

This balanced approach can help protect structures while reducing unintended effects. Always follow product labels and local guidelines; for complex situations, consider consulting a licensed pest professional.

Choose based on where you see activity and how you want to treat it.

• Foam: Best for injecting into galleries; it expands to reach hidden spaces. Look for cans around 18 oz if you’re tackling a few holes.
• Ready-to-use spray: Good for treating surfaces and high-traffic zones; a trigger sprayer or aerosol can helps cover larger areas (up to 1 gallon formats).
• Traps: Chemical-free and reusable options hang outdoors near eaves to help reduce activity.

Check labels for “carpenter bee,” indoor/outdoor use, and notes like non-staining or odorless. If you’re tackling multiple areas, combining a foam (for galleries) with a surface spray and traps can be practical. You can also filter by size and pickup or delivery options at checkout.
