Carpenter bees build their nests in burrows in almost any outside unpainted or unfinished wood. Sometimes you can’t see the holes; all you see is the ejection matter from their boring. They typically cause cosmetic damage instead of structural damage to wood. However, many generations of carpenter bees can cause considerable wood damage by enlarging existing galleries in wood. They sometimes create new tunnels near old tunnels. A complex system of tunnels can cause extensive damage to wood.
To prevent carpenter bee damage, keep all exposed wood services well painted with a polyurethane or oil-based paint. Paint everything, even the areas you can’t see including under banisters, railings and window seals. Apply two coats of a good exterior primer and follow up with at least one coat of finish.
Continually perform inspections of painted surfaces because the paint coating deteriorates due to weathering, leaving exposed wood for carpenter bees to attack. Also, seal existing gallery entrance holes to discourage carpenter bees who are looking for potential nesting locations.

If you choose to cover wooden components with aluminum do it correctly. You can’t leave any spaces where carpenter bees can find wood. They can squeeze through very small spaces.
