Carpenter bees are a common seasonal pest throughout New Jersey, Pennsylvania, Delaware, and the Eastern Shore of Maryland, and if you own a home in the region, chances are you’ll encounter them at some point. While they may look similar to bumblebees, their behavior and the damage they cause to wood structures make them a very different kind of problem for homeowners.
Understanding how carpenter bees behave, where they nest, and how to stop them early can save you from expensive structural damage—and in many cases, prevent a growing infestation before it starts.
A carpenter bee is a native insect found across much of the United States. They are large, often around one inch long, and are most commonly mistaken for bumblebees due to their similar size and coloring.
Unlike social bees, carpenter bees are solitary. They do not live in large hives. Instead, they bore into wood to create individual nesting tunnels where they lay eggs and raise their young.
Carpenter bees are fairly easy to recognize once you know what to look for:
A key sign of carpenter bee activity is the presence of clean, round holes in untreated or unpainted wood, often about the size of a dime.
It’s easy to confuse carpenter bees with bumblebees, but there are important differences:
Bumblebees are fuzzy, social insects that nest in the ground or in colonies. Carpenter bees are smoother, more metallic-looking, and prefer to drill into wood rather than live in groups.
This nesting behavior is what makes carpenter bees a concern for homeowners—not their presence alone, but the damage they leave behind.
Carpenter bees don’t eat wood, but they tunnel into it to build nesting galleries. Over time, these tunnels can become extensive—sometimes stretching deep into beams, decks, fascia boards, and siding.
This can lead to:
Decks, porch railings, sheds, eaves, and untreated wood surfaces are especially vulnerable.
Carpenter bees prefer soft, unfinished, or weathered wood. Around the home, they are commonly found in:
One of the biggest risk factors is exposed or unsealed wood. Once bees establish tunnels, they often return to the same area year after year and expand existing damage.
In the Northeast region, carpenter bees typically become active in spring as temperatures warm. This is when they begin mating, drilling new nesting tunnels, and expanding existing ones.
They remain active through spring and summer, then overwinter inside their tunnels, emerging again the following year. This cycle makes early prevention especially important.
Carpenter bees are generally not aggressive, but there are differences between males and females:
In most cases, the real issue is not stings—it’s the structural damage they cause over time.
The most effective way to discourage carpenter bees is to make your home less attractive to them:
Prevention helps, but once carpenter bees establish active tunnels, DIY methods often fall short of fully eliminating the problem.
Carpenter bee infestations are difficult to control once they spread into multiple nesting sites. Even if you plug visible holes, bees may already be deeper inside the wood—or may simply drill new entry points nearby.
That’s why many homeowners turn to professional treatment instead of trying to manage the problem alone.
A targeted pest control approach focuses on:
When carpenter bees start damaging your home, fast action matters. That’s where Viking Pest Control comes in.

Instead of guessing or relying on temporary fixes, homeowners get a complete solution that protects both the structure and value of their property.
Carpenter bees may seem like a minor nuisance at first, but the damage they cause builds over time. What starts as a few small holes can turn into weakened boards, structural repairs, and recurring infestations year after year.
If you’ve noticed signs of carpenter bee activity—or want to prevent them before they start—the safest move is to bring in a professional early.
