Key takeaways
- Hardie board is fiber cement, so termites cannot eat or tunnel through the siding itself.
- The real risk is termites in the wood framing and substrate behind the siding.
- Removing old wood siding often reveals existing termite damage in headers and 2x4s.
- Hardie siding will not stop termites that are already in your home or on your property.
- Pairing James Hardie siding with active termite control gives your home the best protection.
Termites often go unnoticed for months while they quietly damage a home, so pest resistance ranks high when homeowners shop for new siding. Fiber cement has earned a reputation for toughness, which leaves plenty of property owners wondering whether termites can get into a Hardie board. The honest answer comes down to two things: the siding itself and the wood framing behind it, and that difference matters more than most people expect.
Can Termites Get into a Hardie Board?
The siding itself is not the problem. James Hardie board is fiber cement, a blend of cement, sand, and cellulose fibers, and that makeup keeps termites from getting a foothold.
Why Fiber Cement Resists Termites
Termites feed on the cellulose in solid wood. Fiber cement gives them no food source and no path to chew through, which is why Hardie board is termite-resistant. The siding stays intact even when the wood around it does not.
Is Hardie Board Woodpecker Resistant Too?
Yes. Woodpeckers come up almost as often as termites, and James Hardie holds up well against them. Plenty of homeowners who replaced damaged wood siding with Hardie report no more woodpecker holes, since birds gain nothing from pecking at fiber cement.
Pro Tip: Fiber cement resists termites, but it does not treat them. If pests are already active, deal with the infestation before or during your siding project.
The Real Termite Risk Sits Behind the Siding
The bigger concern is the wood behind the boards, where termites that are already in your framing or on your property can keep causing damage.
Can Termites Get Into a Hardie Board From the Framing?
Termites do not move into the board, but they can keep feeding on the wood it covers. That framing is cellulose, exactly what termites are after, and new siding hides it without protecting it.
What We Find When We Remove Old Siding
Pulling off old wood siding often exposes termite damage underneath. Common trouble spots include:
- Headers above windows and doors
- 2×4 studs inside the wall framing
- Sheathing and other substrates
Hardie board installed over that damage does not repair it or stop it from spreading.

How We Help You Protect Your Home
Stopping termites takes more than new siding. It takes the right pairing of durable materials and active pest control, and that is where our experience makes the difference.
Pair Hardie Siding with Termite Control
As the largest James Hardie installer in the Kansas City metro, we have removed enough old siding to know how often termites hide in the wall framing. We recommend treating any active infestation with a licensed pest professional, then installing Hardie board over sound, dry framing.
Start With a Professional Inspection
Before a single board goes up, we check the condition of the wood underneath. If we find damage, we point it out and make sure the structure is solid before new siding goes on.
Key Takeaway: Hardie board protects the surface of your home, and professional termite treatment protects the structure. You want both working together.
Frequently Asked Questions
- Do termites eat Hardie board?
No. Hardie board is fiber cement, not wood, so there is nothing in it for termites to feed on.
- Can termites get into a Hardie board after it is installed?
The board stays safe, but termites can still damage the wood framing behind it if an infestation is already present.
- Is James Hardie woodpecker resistant?
Yes. Hardie board is too hard for woodpeckers to damage, so bird problems usually fade once it is installed.
- Will new Hardie siding stop an existing termite problem?
No. Siding covers the wood but does not treat termites. A licensed pest professional is the right call for that.
- How do I know if termites are behind my siding?
A professional inspection before or during a siding project is the most reliable way to check headers, studs, and substrate.
Stop Termites Before They Spread
Fiber cement gives termites nothing to eat, so the siding holds up well. The damage that matters happens in the wood underneath, which is why pairing James Hardie with proper pest control is the smart move. Our local experience helps catch problems early and protect what sits beneath your siding.
