Fumigation for Furniture Infestations: When It Is Needed

Fumigation uses gas to penetrate wood and kill borers throughout an item. It is a stronger option, used when other methods will not reach all the larvae.

The short answer

Fumigation is used for heavy or deep infestations, large amounts of furniture, items with hidden or inaccessible tunnels, or when other treatments have failed. It is done by trained professionals in sealed chambers or under covers, with the home vacated and ventilated afterwards. Because it needs preparation and safety measures, it is not a DIY option. Ask the provider about the method, the time, the aftercare and what is covered.

When fumigation may be considered

• Large infestations across many items.
• Valuable pieces where tunnels cannot be reached by injection.
• Items that cannot be treated by heat.
• Repeated infestations after other treatments.

What happens

1. Inspection and decision on whether fumigation is necessary.
2. Items are placed in a chamber or sealed under covers.
3. Gas is introduced for the specified time by trained staff.
4. The area is aired until safe.
5. Items are returned or the home reoccupied as advised.

Safety

• Only licensed professionals should fumigate.
• People, pets and plants must leave during treatment.
• Follow aeration times before returning.
• Remove food and sensitive items as advised.

Limits

• No lasting protection against new infestation.
• Does not repair damage.
• Moisture and sealing still matter.

When to call a professional

Fumigation should only be performed by licensed professionals. Ask for details on safety and aftercare.
