KIRK: You have termites … Tens of thousands of them. Subterranean, drywood, the whole gamut.
Termites are an insect closely related to cockroaches, and sometimes called “white ants”, although they aren’t ants, or even close to them. They are considered a pest because of their wood-eating habits, and can cause significant damage to wooden structures.
There are three groups of termites: dampwood, drywood, and subterranean, which would be the “whole gamut”. Subterranean termites live underground in nests or mounds, dampwood termites eat wood exposed to rain or soil, while drywood termites thrive in warm environments – which, if you live somewhere cold, means that they live living in your nice warm wooden house!
It seems unlikely that Lorelai has all possible types of termites, but it also seems unlikely Kirk is qualified as a termite expert. She almost certainly has a serious infestation of drywood termites.
