Common Treatments for Killing Termites

Termites can be a serious pest problem and should be dealt with as soon as possible when you discover them.

There are a number of options that an exterminator has to take care of a termite problem, so it’s not automatically going to be a fumigation situation. Different situations can call for different measures. Talking to your local experts, like Lexington exterminator Fox Pest Control can help you figure out the best course of action when you discover termites.


We may as well start with the most familiar one: fumigation. This is a bit of a drastic choice and usually only performed for extensive infestations that can’t be treated more directly.

A huge tent is put up around your home and filled with a a pesticide gas (usually sulfuryl fluoride). The gas permeates all the air spaces in the home, killing termites in even the most inaccessible places, taking up to 3 days for the entire treatment to be completed.

Once it’s done, the house is opened up to ventilate. The fumes should not leave any residue behind, so exposure to anything toxic is minimal though all food items must be removed from the house before treatment.

Pesticide Baits

This is a newer treatment option, similar to what is used for other pests like ants or roaches. Insecticides are combined with a cellulose material (since termites only eat wood), which make them effective baits. Baits are ideal for small or new termite populations that haven’t gotten too entrenched, and they are less invasive in your home to use. Anyone who is concerned about the toxic nature of sprays or gas should talk to their pest control professional about using baits.

Wood Treatment

Simply spraying the wood with termites is a common treatment for smaller problems, though only the surface gets treated and it may not be as effective as other choices. This is also the most common DIY option, using a solution of boric acid (i.e. Borax) applied to infested wood. You can also treat wood with boric acid, or other pesticides, as a preventative.

Soil Treatment

You can also tackle a termite problem by treating the soil around your home with an underground insecticide. This creates a barrier to prevent termites, which only move around via underground tunnels, from reaching your home.

This option only works if there are currently no termites already living inside the house. So any insects inside will have to be dealt with separately, or you can use this choice before you actually have an indoor problem, as a method of prevention.

Temperature or Moisture Treatments

For a non-chemical approach, you can eliminate small communities of termites by making their environment unlivable. They need a fairly high level of humidity to survive, so hot air can be used to kill off colonies, provided they are in a location where it can be applied effectively.

Once you’ve found an effective termite treatment, remember to use further barrier methods (like covering any exposed wood in your home) or applying insecticide to the soil outside to prevent any recurring infestations.
