1. Sunlight

How to Kill Termites Naturally: Using SunlightUsing Sunlight to Get Rid of Termites

Termites are designed to live in the dark and being exposed to sunlight can wreak havoc on their colony.

The sun is a very simple natural way to get rid of termites and is completely free to take advantage of. All you have to do is make sure that the infestation is exposed and let the sun do the work.


Once you’ve found where the termites are hiding, expose the area to sun by clearing out nearby brush and moving any objects that are providing shade. Without anything to block the sun’s rays, the termites will die.


Simply place the furniture outside in an area where it will get direct sunlight for as many daylight hours as possible.

For furniture that termites can hide inside, you can also use some bait (like the cardboard trap described below) to help lure them out so they’re more likely to be exposed to the sun.

2. Heat and Cold Treatments

Changing the temperature around the colony is a natural way to get rid of termites that uses absolutely no toxic materials to take care of the problem.

Heat Treatments

Heat treatments are done by pest control professionals and can be used for your whole house or just for furniture.

To have your home treated, a specialist will come for an inspection to find where the termites are located and recommend what items should be taken out of your home for the treatment.

On the day of treatment, heaters will be set up to raise the temperature in your house to between 120 and 140 degrees Fahrenheit for at least 35 minutes.

To treat furniture, the infested items can be put in a heat chamber and exposed to the same heat for up to four hours.

Cold Treatments

Cold treatments are usually used for furniture or for treating specific spots of high activity.

Liquid nitrogen is a non-toxic natural termite killer that can be used to freeze out the pests. This method is typically carried out by a specialist who will pump liquid nitrogen into the infested areas.

If you live somewhere where winters reach temperatures below 20 degrees Fahrenheit, you can put your furniture outside on cold days for the same effect.

These temperatures are just too low for termites to survive and most or all of the termites in the treated area will die from exposure.

Sometimes what kills termites is completely safe and even beneficial for humans. Usually used in the form of a white powder, diatomaceous earth is a type of sedimentary rock that is deadly for termites but some people use a food-grade variety as a supplement.

Diatomaceous earth can be used both indoors and outdoors, so try applying it to exposed wood, furniture, and even carpets and rugs. Anywhere you’ve seen termites is a good place to sprinkle some since it’s so safe to use.

2. Orange Oil

Orange oil is an essential oil made from the fruit’s rinds and can be found in many natural health stores. It contains D-limonene which kills termites and many other common pests on contact by drying out their exoskeletons.

While it’s generally safe for people and pets, it can be irritating if it makes direct contact with your skin undiluted and can cause digestive upset if ingested, so you should still be careful when using it.

Apply orange oil diluted in water to infested wood, especially in the cracks where termites might hide. It can be helpful to drill well-spaced holes into the wood to get the solution farther inside.

There are also orange oil-based products available. Orange Guard and XT-2000 are the most commonly used options.
