Which treatment methods and products are most effective?

Another challenging question. There are two general categories of termite treatment, liquids and baits. Soil-applied liquid products have been around for decades. Their purpose is to provide a long-lasting chemical barrier that excludes termites in the ground from entering buildings. In most cases, termites in the structure die off as well, since they cannot return to the soil. Most former products were repellent rather than lethal to termites foraging in the soil. Newer materials, such as Premise® and Termidor® are non-repellent and termites tunneling into the treatment zone are killed. Overall the non-repellent products are proving to be more reliable in their ability to resolve termite problems in the first attempt. All registered products(both repellent and non-repellent) can be effective, however, and homeowners should not base their purchasing decision on product alone.

The other broad treatment category is baiting. Termite baits consist of paper, cardboard, or other palatable food, combined with a slow-acting substance lethal to termites. The baits are installed below ground out in the yard in cylindrical plastic stations. Others are sometimes placed indoors over active mud tubes. Foraging termites consume the bait and share it with their nest mates, resulting in a gradual decline in termite numbers. On some properties, baits may constitute the only form of treatment; on others, they may be combined with liquid applications. to areas where termites are observed.

Termite baiting is a very complex subject. Regardless of which method or product is selected, it’s important to have an experienced technician, backed by a responsible pest control firm.
