Colony collapse of Eastern subterranean termites
Snapshot: Termite colonies in laboratory and field tests were rapidly eliminated using a trap, treat and release method with commercial termite toxicants and a patented termite bait developed at the Forest Products Laboratory. Characteristic changes occurred in termite colonies that were on the verge of collapse after the dual treatment, including increased susceptibility to infestation with mites, bacteria and fungi.
