2 min readAre carpenter bees calling your patio home this summer? As temperatures rise, insects come out of the woodwork—literally, in the case of carpenter bees. As the name suggests, these bees nest in wood, often in trees. But they will burrow in an aging deck, a decaying pile of firewood, your house’s siding, or any other prime real estate when given the opportunity.
If carpenter bees have their sights set on your property, rest assured that these particular bees are generally nonthreatening to humans. The large, loud male carpenter bees swarming your barbecue don’t actually have stingers. While their female counterparts do have the ability to sting, they rarely do unless provoked. Though not physically dangerous, these pests can cause significant damage to wood structures, especially when they return season after season.
To better understand how to get rid of carpenter bees safely and effectively, we spoke with pest management experts for their advice. Here’s what to know.

How Much Damage Can Carpenter Bees Do?
Master beekeeper Mateo Kaiser, founder of the swarm-reporting app Swarmed, says carpenter bees tunnel into wood, rather than consuming wood like termites. This behavior can weaken the integrity of wooden structures over time.
“The tunnels can become extensive, leading to potential structural damage,” Kaiser says. “Additionally, their holes create entry points for moisture, increasing the risk of wood rot and attracting secondary pests like ants and woodpeckers.”
Jim McHale, entomologist and president at JP McHale Pest Management, adds that carpenter bees’ material waste can stain wood as they burrow. Additionally, these bees lay eggs in sunny areas—constructing six egg chambers at a time. If several bees choose the same egg-laying area, infestations can span up to 10 feet of board, according to McHale.
What Are the Signs of a Carpenter Bee Nest?
Look for “perfectly round, dime-sized holes in exposed, unpainted softwoods—usually under eaves, decks, railings, or fascia boards,” according to Jason Napolski, the president and CEO at A-Tex Pest Management. These nests are the first clue that carpenter bees are your new neighbors.
You may also notice yellow stains and the accumulation of fine sawdust piles. These red flags might signal it’s time to take action against carpenter bees.
How to Get Rid of Carpenter Bees
If you notice structural damage from carpenter bees or extensive tunneling, Kaiser advises calling pest control specialists. “Pest control professionals have the tools and knowledge to treat the tunnels safely and seal them, preventing future infestations and further damage,” he says.
As for natural safeguards, Kaiser recommends applying citrus oil or almond oil around infested areas to prevent nesting. A fascinating DIY solution is hanging wind chimes, especially in sunny, carpenter bee-friendly areas. He claims that the vibration of the chimes can actually deter these pests.
Finally, Kaiser stresses that seasonal upkeep, like giving wood a new coat of paint or sealing, is “the most effective long-term preventative measure.” Carpenter bees flock to untreated and weathered wood, so go ahead and take that as your sign to refresh your exterior paint.
