Those little holes might be doing more damage than you think!
During a recent inspection, I noticed damage on the fascia board of a neighboring property that fits the typical appearance of carpenter bee activity.
Carpenter bees don’t eat wood like termites. Instead, they bore into wood to create tunnels for nesting. Their entry holes are usually round and about ½ inch in diameter. Over time, repeated nesting and expanding tunnels can weaken fascia, trim, decking, and other exposed wood.
🔎 Signs to watch for:
• Nearly perfect round holes in exposed wood
• Sawdust or wood shavings below the holes
• Yellow/brown staining around entry points
• Bees repeatedly hovering near fascia, soffits, decks, or trim
• Woodpecker damage around areas where bees have nested
🛠️ Ways to help prevent carpenter bee damage:
• Keep exterior wood properly painted, stained, or sealed
• Repair deteriorated or exposed wood
• Pay particular attention to fascia, soffits, railings, decks, and other unfinished wood
• Have active infestations properly treated before sealing existing holes
• Periodically inspect previously affected areas, since carpenter bees may return to old nesting sites
This is another reason the exterior inspection is more than just looking at siding and shingles. Sometimes a small hole can tell a much bigger story.
