How to Prevent and Get Rid of Pests in Firewood
Firewood piles are a useful resource for heating and outdoor recreation, but they are also one of the most common sources of pest activity around homes. Wood stacked outdoors can attract ants, beetles, termites, rodents, and other pests that nest, hide, or feed in the wood. If firewood is stored too close to the home or brought indoors without inspection, these pests may accidentally end up inside your living space.
Here is how to prevent infestations, identify common firewood pests, and keep your home protected.
Pests Commonly Found in Stored Firewood
Several pests use firewood as shelter or a food source. Most of them are harmless once brought indoors, but some can cause structural problems when they spread into nearby buildings.
Termites and Powderpost Beetles
Termites and powderpost beetles are the most destructive pests linked to firewood.
- Termites are more likely to infest logs stored directly on soil or stacked close to the home.
- Powderpost beetles prefer wood that contains moisture or has not fully dried.
- Small exit holes, sawdust-like frass, or fine powder are signs of activity.
Importantly, pests found in firewood typically do not establish colonies indoors unless moisture and wood conditions are ideal.
Beetles, Weevils, and Carpenter Ants
Other insects commonly found in firewood include:
- Bark beetles
- Woodboring beetles
- Weevils
- Carpenter ants
These pests usually remain in the wood unless temperatures rise sufficiently after the logs are brought inside. Carpenter ants may also nest in damp wood stored outdoors.
Why Pests Are Drawn to Firewood
Firewood attracts pests for several reasons:
- It provides shelter, protection, and warmth.
- It holds moisture, creating ideal conditions for insects.
- It offers food sources for wood-destroying pests.
- It sits undisturbed for months at a time.
Wood piles positioned near vegetation or soil increase the likelihood of infestation.
How to Prevent and Get Rid of Pests in Firewood
1. Keep Firewood Off the Ground
Store firewood on a raised rack at least 6 to 12 inches above soil.
This prevents moisture buildup and makes it harder for pests to access the wood.
2. Store Firewood Away from Your Home
Maintain a distance of at least 20 to 30 feet between your home and your woodpile.
This prevents pests like termites, ants, and rodents from bridging the gap and accessing your structure.
3. Cover Wood Properly but Allow Airflow
Use a breathable cover that sheds rain but allows the stack to dry.
Avoid wrapping wood completely in plastic, which traps moisture and encourages pest activity.
4. Use Older Wood First
Rotate your supply and burn older, seasoned firewood before newer logs.
Pests are less likely to survive in long-dried wood.
5. Bring Wood Indoors Only as Needed
Move only a small amount of wood inside at a time.
Most firewood pests die quickly once removed from outdoor conditions but should never be given time to explore the home.
6. Inspect Wood Before Bringing It Inside
Look for:
- Sawdust
- Holes
- Soft or crumbly sections
- Clinging insects
- Signs of moisture
Knocking logs together can dislodge many pests before transport.
7. Avoid Using Homemade Chemical Remedies
Vinegar, lemon juice, soap sprays, or food scraps do not prevent wood-infesting insects and may attract additional pests or wildlife.
When chemical treatment is needed, use only products labeled for structural pest control or contact a professional.
8. Consider Kiln-Dried Firewood
Kiln drying eliminates insects during processing.
This is the best option for homeowners wanting pest-free firewood.
When to Call a Professional
