Carpenter Bees and Wooden Swing Sets: What New Jersey Homeowners Should Know

Protecting Your Wooden Swing Set from Carpenter Bees

Wooden swing sets are a timeless addition to backyard play spaces across New Jersey. Cedar and redwood playsets offer natural beauty, durability, and long-lasting outdoor fun for families. However, these same qualities can also attract carpenter bees.

If you’ve noticed perfectly round holes appearing in your wooden swing set, there’s a good chance carpenter bees are the cause. While these bees are generally less aggressive than wasps or hornets, they can still create problems for homeowners if left untreated.

Understanding how carpenter bees behave, how they affect wooden playsets, and how to prevent future nesting can help protect your investment and extend the life of your backyard playground.

Why Carpenter Bees Are Attracted to Wooden Swing Sets

Many homeowners ask if bees are attracted to cedar wood, and the answer is yes. Carpenter bees are commonly drawn to softwoods like cedar, redwood, pine, and cypress because these materials are easier for them to tunnel into.

Unlike termites, carpenter bees do not eat wood. Instead, they drill into exposed wood surfaces to create nesting tunnels for their eggs.

These tunnels typically begin with:

• A small round hole about 1/2 inch wide
• A short vertical tunnel into the wood
• A longer tunnel following the wood grain

Female carpenter bees create sections within the tunnel for eggs, separating them with pollen and nectar that feed developing larvae.

While occasional nesting may not immediately damage a swing set, repeated activity over time can weaken structural components and create openings for moisture and rot.

Signs of Carpenter Bee Activity

The earlier you identify carpenter bee activity, the easier it is to prevent long-term damage to your wooden playground equipment.

Common signs include:

• Perfectly round holes in wood surfaces
• Sawdust beneath swing set beams or platforms
• Bees hovering near wooden structures
• Light staining around tunnel entrances
• Increased bee activity in spring and early summer

Carpenter bees are especially active during warmer months throughout New Jersey.

How to Prevent Carpenter Bees in Wooden Playsets

Preventative maintenance is one of the best ways to protect your playset from carpenter bees. Although no method is completely foolproof, several strategies can significantly reduce nesting activity.

Paint or Stain the Wood

One of the most effective deterrents is applying paint or stain to exposed wood surfaces. Many carpenter bees prefer unfinished wood, making stained or sealed surfaces less attractive.

Oil-based stains are especially effective because they help seal the wood while improving weather resistance and appearance.

Proper maintenance also helps preserve the longevity of your playset. Learn more about our swing set accessories and maintenance products designed for outdoor playground equipment.

Use Natural Carpenter Bee Repellents

Some homeowners apply natural deterrents such as:

• Citrus oil
• Tea tree oil
• Almond oil

These strong scents may help discourage bees from nesting near wooden structures.

Install Carpenter Bee Traps

Carpenter bee traps can help reduce bee activity around your property. These traps attract bees into a chamber where they cannot escape, helping minimize future nesting near your swing set.

What to Do If Carpenter Bees Are Already in Your Swing Set

If carpenter bees have already created tunnels in your playset, addressing the problem quickly can help prevent additional nesting.

A common treatment process includes:

1. Using a stiff wire to reach deep into the tunnel
2. Applying carpenter bee spray or approved pesticide into the opening
3. Waiting until activity stops
4. Sealing the hole with durable wood putty

Filling the tunnels is important because carpenter bees often return to old nesting holes and expand them over time.

If you notice holes later in the season, especially toward the end of summer, simply sealing inactive tunnels may be enough to prevent future problems.

When to Call an Exterminator

For severe infestations or recurring carpenter bee activity, contacting a professional exterminator may be the best option.

An exterminator can:

• Treat active nesting tunnels
• Apply professional-grade pesticides
• Identify hidden nesting areas
• Help reduce repeat infestations

After treatment, it’s still important to fill existing tunnels to prevent bees from returning the following season.

Protecting Your Swing Set Long-Term

Regular maintenance is key to extending the lifespan of wooden playground equipment. In addition to carpenter bee prevention, homeowners should routinely inspect for:

• Moisture damage
• Loose hardware
• Cracks or splintering
• Ground contact deterioration

Many families also install protective playground surfacing beneath their playsets to improve drainage and reduce moisture exposure around support posts.

If your swing set sits on uneven terrain, products like LevelDry leveling blocks can also help improve stability and reduce ground-related wear over time.
