Asian subterranean termites (Coptotermes gestroi) are commonly targeted with an insecticide bait known as a chitin synthesis inhibitor (CSI). A new study shows exposure to CSI baits for as little as one day may be sufficient to eliminate a termite colony.
Successful management of subterranean termites depends in part on eliminating colonies.
CSIs are used in a dry bait, as opposed to the wet formulations used with some other termite insecticides. The dry baits offer the advantage of being less damaging to the environment, because only the termites that feed on baits are affected. The effectiveness of CSIs is also heightened because termites first killed by the insecticide are consumed by other termites--and then they become exposed to the CSI. An additional advantage is that CSIs reduce the need for liquid insecticides, which can be more damaging to the environment. Read more about this compelling study at Entomology Today.
