Termite Control Protection & Treatment

The Sentricon system is marketed as a termite colony elimination system. In order for a colony elimination system to work, the bait must affect every termite in the colony. Worker termites do all of the foraging, so how does the bait get from the worker termites to the rest of the colony?

Remember that the worker termites are responsible for feeding all of their nestmates. They do this by consuming food themselves then regurgitating part of it into the mouths of the other colony members. This same natural behavior is exploited by the Sentricon termite control system to disperse the bait toxicant throughout the termite nest.

It is important to note that the bait cannot work too fast. If the active ingredient killed the termites too rapidly, the worker termites would die before they could pass the bait to other colony members.

The active ingredient in the Sentricon bait is hexaflumuron, a slow acting toxicant. Hexaflumuron is an insect growth regulator (IGR). IGRs interfere with the insect's physical development. This particular IGR interferes with the insect's ability to molt. Insects have their skeleton on the outside of their bodies, an exoskeleton.

In order to grow larger they must periodically shed this exoskeleton in a process called molting. Hexaflumuron, a chitin synthesis inhibitor, inhibits the termites' ability to produce chitin (skin substance). Hexaflumuron does not allow the termite to molt properly so it dies in the process.

As worker termites feed on the bait material, they transfer the Hexaflumuron throughout the entire colony via a process known as "trophallaxis". When hexaflumuron is passed from one termite to another the affected termites die during their next molt. In time, there are too few termites left to take care of the colony and feed the queen. When the queen dies the colony is eliminated.

The Sentricon termite control system also supplies above ground stations that the pest control operator (PCO) can place directly on termite mud tubes or infested wood. Hexaflumuron is the active ingredient in the above ground stations as well.
