Why Do Termites Return?

In most cases, termites can come back after treatment, especially if certain conditions are present.

There are few reasons why this might happen…

• Incomplete treatment – If the treatment didn’t fully target all the areas where termites are hiding or nesting, they may return.

• New colonies – Termites live in colonies, and while one colony may be eliminated, others in the area can move in.

• Structural weaknesses – If your home has undetected weaknesses (like untreated cracks or gaps in the foundation), termites might find a new way in.

Types of Termite Treatments & Their Effectiveness

The effectiveness of treatment depends on the type used…

Liquid Soil Treatments

• How it works – Termite-killing liquid is applied to the soil around your home to create a barrier.

• Can termites return? Liquid treatments can be highly effective for numerous years, but termites may return if the barrier is disrupted, or if there are gaps in coverage.

• Duration of protection – 5 – 10 years, depending on the product.

Baiting Systems

• How it works – Bait stations are placed around the property, luring termites to feed on poison that kills the colony.

• Can termites return? Baiting systems can take longer to show results, & if not continuously maintained, termites might find another food source.

• Duration of protection – Long-term with regular maintenance, but reinfestation can occur without ongoing monitoring.

Fumigation

• How it works – The entire structure is sealed and treated with gas to kill termites inside.

• Can termites return? If there are other colonies nearby, termites can return after fumigation once the treatment effect fades.

• Duration of protection – Usually 1-2 years without re-treatment, though fumigation eliminates termites already present.

How to Prevent Termites From Returning

While no treatment guarantees termites won’t return, here are steps you can take to reduce the risk of reinfestation…

• Regular inspections – Schedule annual termite inspections to catch any early signs of new activity.

• Eliminate moisture – Termites are attracted to moisture. Fix leaky pipes, ensure proper drainage around your foundation, & keep gutters clean.

• Seal entry points – Inspect your home for cracks, gaps, and openings, particularly in the foundation and around doors/windows. Seal any gaps to prevent new colonies from entering.

• Remove wood from around the home – Termites thrive on wood, so keep firewood, mulch, and other wood-based materials away from your house.

• Maintain treatment systems – If you’re using baiting systems or a liquid treatment barrier, make sure they are regularly maintained and replenished.

Termites can come back after treatment, the right preventative measures & regular maintenance can greatly reduce the likelihood of reinfestation. Choosing the right treatment & being proactive with inspections and repairs will give you the best chance of protecting your home long-term.
