How Long Does Termite Treatment Last?

There are several different options for termite treatment at home. Some of these treatments are more appropriate than others depending on the type of infestation you have, how much damage has already been done, and whether or not the infestation is active or dormant. Maybe you have been trying to figure out what the best termite treatment is and asking, “How long does termite treatment last? Here are some of the most common treatment options:

Termite bait treatment

Termite baits are a form of treatment that uses a slow-acting poison to kill termites. A bait station is installed near the infestation, and then bait is placed inside the station. The termites take the bait back to their nest and feed it to other members of their colony. After feeding on the bait, they die within days or weeks depending on how quickly they ingested it.

However, if there’s a lot of wood in your home (like joists) or if there’s already a lot of damage from previous infestations, then it may take longer for them to die off completely. These treatments can last for about five years before retreatment is required.

Liquid treatment

Liquid treatment involves injecting insecticides into the ground around your home with a pump truck or other equipment in order to kill off any subterranean colonies that may be present beneath your property’s surface. The liquid kills the pests when they come into contact with it.

It can be used to treat individual buildings or entire neighborhoods at once if there are several homes with a similar problem; however, it may take several weeks for this treatment to work fully — especially if there’s already significant damage from previous infestations present when you begin treatment. This treatment lasts anywhere from two to five years before retreatment is needed.

Foam treatment

This is a type of chemical that kills termites by blocking their breathing system. You simply spray the foam onto the ground around your home and then let it dry before it expands into solid foam blocks that prevent access by termites. This method is very popular because it can be used in any type of soil, including sandy areas where other methods would have trouble staying effective over time. Foam treatment usually lasts for about 3 years before retreatment is needed (although some brands claim longer).

Solid treatments

This option involves placing granular material around your home’s foundation, typically in trenches filled with water or oil. The material kills any termites that walk over it, but can be difficult to apply properly. If the trenches are not properly maintained and cleaned out periodically, they could become clogged with dirt and debris. The treatment usually lasts between one and three years before it needs to be reapplied again.


Fumigation involves using chemical vapors to kill termites inside their nests as well as any eggs or larvae that may still be there at the time of treatment. This method is effective for about five years after treatment before retreatment is needed again.

Bottom line

When you’re dealing with termites, you need a long-term solution that will protect your home for years to come. While there are many types of treatments available, knowing how long they last and what kind of protection they provide can help you decide which one is right for your situation.
