How Treating Subterranean Termites With Termiticide Works

Pest Control

Liquid termiticide is used to eliminate subterranean termites. Subterranean termites form nests in the soil and build mud tubes to their food source – the wood in your home or structure. To stop them, a liquid termiticide is injected into the soil around your home or structure. The termiticide forms a chemical “barrier” that stops the termites from burrowing into your house (Green Heat SD).

There are 2 types of termiticides – repellant and non-repellant. Repellant termiticides rely on turning the termites away and forcing them to forage elsewhere. Non-repellant termiticide is undetectable by termites and will kill them upon exposure.

Average Cost

Termiticide treatments are generally charged by linear foot, ie, the perimeter of your house, not the square footage. Rates can range from roughly $4 to $15 per square foot.

Application Time

Liquid termiticide can be applied by a technician within 1 day.

Treatment Time

Liquid termiticide provides for immediate protection and remains effective in the soil for several years.

Hassle Factor

The application of liquid termiticide involves drilling around and (if possible) underneath a structure by a technician. Little to no preparation is required of the property owner.


  • Is intended to provide immediate protection to the structure and to last for several years.
  • Liquid termiticide is one of the cheapest ways to combat subterranean termites.


  • Even the most thorough liquid termiticide application can have gaps that termites can pass through.
  • A liquid termiticide applied within 50 feet of running water, a well, or cistern is a water contamination risk. While it is not illegal to apply a liquid termiticide within 50 feet of a water source, over time the chemicals may eventually seep into the water.
