Carpenter Bee Control in Michigan

Carpenter bees are often mistaken for bumblebees because of their size and appearance, but unlike bumblebees, carpenter bees drill into wood to create nesting tunnels. While they don’t eat wood like termites, their drilling can weaken decks, siding, fences, and outdoor structures over time. In Michigan, carpenter bees are especially active during spring and early summer, when females create tunnels to lay eggs.

At Parshall Pest Control, we provide safe, effective carpenter bee control services to protect your property from damage. Our trained technicians identify activity areas, treat existing infestations, and implement preventive strategies to keep carpenter bees from returning. If you’ve noticed round holes in wood or buzzing activity around your home, it’s time to act before the problem worsens.

Why Carpenter Bees Are a Problem

Carpenter bees may not pose the same aggressive threat as wasps or hornets, but they can cause costly property damage when left untreated. Female carpenter bees bore perfect, round holes into untreated or weathered wood, creating long tunnels where they lay eggs. Over time, multiple bees reusing the same tunnels year after year can cause significant weakening of wooden structures such as decks, porches, siding, fences, or sheds.

In addition to the damage caused by the bees themselves, their presence often attracts woodpeckers, which peck at the wood to feed on carpenter bee larvae. This can lead to even more serious and visible structural damage. While male carpenter bees cannot sting, they are territorial and will hover aggressively near people, creating fear and discomfort around your home. Professional treatment ensures colonies are eliminated and wood surfaces are protected against future activity.

Signs of Carpenter Bee Activity

Carpenter bees are relatively easy to spot because of their size and distinctive habits. Look for these common signs of infestation:

  • Round holes about ½ inch in diameter in decks, siding, eaves, or fences
  • Sawdust or wood shavings beneath wooden surfaces
  • Buzzing or hovering bees near wooden structures, especially in spring
  • Woodpecker activity around areas where carpenter bees are nesting
  • Stains or yellowish droppings near entry holes

Unlike termites or carpenter ants, carpenter bees typically don’t infest large areas at once. However, their repeated tunneling and nesting can cause long-term structural concerns if not addressed promptly.

Frequently Asked Questions About Carpenter Bees

Male carpenter bees cannot sting, but females can if provoked. Stings are rare since they are not aggressive by nature.
Carpenter bees drill into wood to nest, while bumblebees nest in the ground or in cavities.
Yes. Each year, new bees may reuse old tunnels, expanding them and causing significant damage.
DIY sprays may kill a few bees but rarely eliminate the entire problem. Professional treatments target bees inside the tunnels for complete control.
Painting, sealing, and treating wood surfaces are the best long-term deterrents, combined with professional treatments when needed.
