Heat Treatment for Wood Borers: Can Furniture Be Treated Without Chemicals?

For people who want to avoid chemicals, heat treatment is an appealing option for wood borers. It is used professionally for wood and furniture, with controlled temperatures.

The short answer

Heat treatment raises the temperature of the wood throughout to a level that kills borers at all life stages, without chemical residues. It is suited to items that can be moved into a chamber or heated in place by professionals. It must be controlled to avoid cracking, glue failure or damage to finishes. It does not protect against future infestation, so moisture control and sealing still matter.

How it works

• The whole item is brought to a target temperature for a set time.
• Larvae, pupae and eggs inside are killed.
• No chemical residue is left in the wood.

Good candidates

• Furniture that can be moved into a chamber.
• Small items and antiques, with expert advice.
• Households wishing to avoid chemicals.

Cautions

• Fast or uneven heating can crack wood or loosen glue.
• Veneers, inlays and finishes may be affected.
• Not suitable for items that cannot be heated safely.
• DIY heating with hair dryers or ovens is unreliable and risky.

After treatment

1. Allow items to cool and stabilise.
2. Repair and refinish if needed.
3. Seal and store properly to avoid reinfestation.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
