If you are noticing large bees hovering around your porch, deck, shed, barn, or wood siding in Missouri, there is a good chance you are dealing with carpenter bees. These wood-boring bees become extremely active during spring and early summer and are common throughout Missouri.
Unlike termites, carpenter bees do not eat wood. Instead, they tunnel into wood to build nesting galleries where they raise their young. Over time, repeated nesting can lead to costly damage to decks, fascia boards, soffits, fences, porch rails, sheds, and other wooden structures.
Why Are Carpenter Bees Targeting My House?
Carpenter bees are attracted to homes with:
- Bare or untreated wood
- Weathered wood surfaces
- Cedar, pine, fir, and redwood
- Wooden decks and railings
- Wooden soffits and fascia boards
- Barns, sheds, pergolas, and fences
- Old carpenter bee holes from previous years
Missouri homes with older exposed wood are especially vulnerable. Carpenter bees often return to the exact same nesting locations year after year, enlarging existing tunnels and creating more damage over time.
Why Are They Boring Holes in My Wood?
Female carpenter bees bore perfectly round holes into wood to create nesting tunnels for their eggs. After entering the wood, they turn and tunnel several inches along the grain of the wood.
Inside these galleries they place:
- Pollen
- Nectar
- Eggs
- Developing larvae
You may notice:
- Perfect round holes about 1/2 inch wide
- Sawdust below holes
- Yellow or brown staining near entrances
- Hovering bees around wooden structures
- Buzzing sounds inside walls or trim
These are classic signs of carpenter bee activity.
Will Carpenter Bees Sting?
Female carpenter bees can sting, but they rarely do unless handled, trapped, or aggressively disturbed. Male carpenter bees cannot sting at all.
Will Carpenter Bees Chase Me?
Many Missouri homeowners think carpenter bees are aggressive because they hover directly in front of people. In reality, this behavior is mostly from males defending territory near nesting sites.
They may:
- Hover near your face
- Fly toward you
- Chase other insects away
- Guard nesting areas
Even though this behavior feels intimidating, males do not have stingers and cannot hurt you.
Are Carpenter Bees Dangerous?
Carpenter bees are generally not dangerous to people, but they can become dangerous to your property over time.
Problems carpenter bees can create include:
- Weakening porch railings
- Damaging deck boards
- Destroying fascia boards
- Creating openings for moisture
- Attracting woodpeckers
- Encouraging wood rot
- Increasing future infestations
Woodpeckers commonly tear apart wood to reach carpenter bee larvae, which can create even more damage than the bees themselves.
Safe Options to Stop and Deter Carpenter Bees
The safest and most effective carpenter bee control combines prevention, exclusion, trapping, and wood maintenance.
1. Paint or Seal Exposed Wood
Carpenter bees strongly prefer untreated wood. Painting, staining, or sealing wood is one of the best long-term prevention methods.
Focus on:
- Decks
- Fascia boards
- Railings
- Soffits
- Fence posts
- Wooden sheds
2. Seal Old Carpenter Bee Holes
Old tunnels attract new carpenter bees every season.
Once activity stops:
- Clean holes
- Fill tunnels with wood filler or dowels
- Caulk openings
- Paint or seal repaired areas
This helps break the nesting cycle.
3. Use Carpenter Bee Traps
Traps can help reduce active carpenter bee populations around decks, barns, sheds, and homes.
4. Natural and Low-Toxicity Repellents
Citrus-based repellents and natural deterrents may help discourage carpenter bees from nesting in treated areas.
Popular repellent options include:

5. Repair and Replace Damaged Wood
Carpenter bees prefer soft, weathered, and moisture-damaged wood. Replacing weakened boards and repairing rotted wood helps reduce future infestations.
Signs You Need Professional Help
You may need professional carpenter bee control if:
- Bees return every spring
- Multiple holes appear yearly
- Woodpeckers are attacking your home
- Decks or railings feel weak
- Bees are entering siding or soffits
- Large numbers are hovering around your home
Heavy infestations often require a combination of treatment, exclusion, repairs, and long-term prevention.
Carpenter Bee Prevention Tips for Missouri Homeowners
Missouri carpenter bee season usually begins in March and peaks during spring and early summer.
To protect your home:
- Inspect wood every spring
- Seal exposed lumber
- Repair old holes immediately
- Install traps before activity increases
- Replace damaged wood
- Reduce moisture problems around wooden structures
Early prevention is far easier and less expensive than repairing long-term carpenter bee damage.
