How To Treat Subterranean Termites

Of all termite species, subterranean termites have the potential to do the most harm. These termites create specialized tunnels to access food sources and shield themselves from the elements.

How To Treat Subterranean Termites

They consume wood continuously by biting off tiny pieces of wood one at a time with their saw-toothed mouths. These can seriously harm a building's structure over time, occasionally leading to a complete collapse. So, here are some suggestions for treating subterranean termites.

Use Baits

It's possible to monitor termite activity early on before infestations flare up using termite baiting, which is a relatively easy technique. The termites consume the bait and return it to the colony to kill as many termites as they can.

Additionally, termite baiting systems impact the entire termite colony, resulting in the death of the whole territory by suppressing the termite population. When used with a barrier or soil treatment, installing bait stations around your property offers excellent control.

Use Termiticide Barriers

These traditional termite treatments are used to build a barrier around the outside of your home. Since termites cannot detect the termiticide, they don't try to avoid it. A termite will perish if it consumes items treated with termiticide.

Additionally, termiticide works by dispersing like a virus. One termite will unknowingly spread the termiticide to other termites, infecting them and eventually destroying the colony when it comes into contact with it.

Use Termidor Foam

This method is ideal if you see a termite and want to eliminate it immediately. Termite-hiding areas like cracks, gaps, and crevices are best treated with Termidor Foam. When the odorless foam expands and evaporates, it leaves behind a poisonous residue that termites will come into contact with. This process lasts a month or longer.

Use Beneficial Nematodes

Although these parasitic roundworms are tiny, they are strong termite hunters. A few days after entering a termite, beneficial nematodes harm their host. Even better, many other garden pests are naturally parasitized by these organisms. If termites are a problem in your outdoor spaces, you can eliminate the infestation by sprinkling potting soil, water, and helpful nematodes over the troubled areas.

Use Diatomaceous Earth

Due to its effectiveness, Diatomaceous earth is frequently suggested as a pest management method. Despite appearing powdered, this substance is abrasive and damages termites' outer shells, leading to dehydration and eventual death. 

It would be best never to use diatomaceous earth without a mask since it can harm the lungs. Use daily by sprinkling a small layer over affected areas. You can also regularly sprinkle diatomaceous earth at the base of your house or other structures to prevent infestations.


Subterranean Termites are dangerous if left untreated. These tenacious pests can quickly destroy your home's foundation, which will be a big problem. If you encounter these in your home and can't treat them, it is time to ask for professional help. Just contact Harper Pest Control for more information and assistance.
