Even the slightest hint of termites means you may need to act fast. Termites aren’t just a nuisance—they can be a budget-ruiner. These pests cause $5 billion a year of damage across homes in the U.S. When you do seek treatment, you have to know how long it will last. You don’t want to risk termites coming back and attacking your home all over again.

This Old House has rounded up all the information you need to know about how long the most popular, effective, and efficient termite treatments last. Our Reviews Team recommends hiring a professional pest control company to apply these treatments.

How Long Termite Treatments Last

On average, termite treatment lasts about 5 years. Liquid termite treatment can last five years or more, whereas termite bait stations only last one year and need to be maintained annually.

Liquid Termite Treatments

These termite treatments last for five years on average. For this treatment, a termite specialist will dig a trench around the perimeter of your home and apply the liquid treatment in it. That’s not to say termites will never find their way across, even in five years. It’s possible some can make their way into your home if there are any gaps in the chemical barrier. Annual termite inspections can help prevent this risk.

Termite Bait Stations

In order to be effective, termite bait stations need to be monitored and maintained year-round. A specialist will place the baits strategically around your property. Termites will take the bait while foraging, and bring the poisonous bait back to their colony, infecting the other termites. However, it could take months for termites to come across the bait stations, so it may take multiple weeks to eliminate the colony.

What Factors Influence How Long Termite Treatments Last?

Those are the average lengths of time the treatments are effective, but the longevity can vary.

Type of Termite

The type of termite can affect the length. Subterranean termites and drywood termites are the most common. Subterranean termites live in the soil around houses and build tunnel networks to access their food—the wood that your house is made of. Drywood termites, on the other hand, tunnel within your wood and eat right through it.

Degree of Infestation

The degree of infestation is a major factor. The larger the termite colony, the longer it will take to eradicate. The level of expertise your termite specialist has will have a big influence since it can determine how complete the application is.

Home Environment

Your home’s set-up also contributes to the longevity of the treatment. Your termite specialist will need to access all the wood components of your home. If these elements are inaccessible or harder to reach, the treatment won’t last as long.
