Formosan subterranean termites are the only known insects that produce naphthalene, the active ingredient in mothballs. This is an imported species in the United States, and is limited to southern states because it needs warm climates to thrive. They are considered a major pest because one colony can have millions of individuals, all preying on any wood in their territory.

The chemical they produce is hazardous to most insects, which is why it is used in mothballs. The termites use this to protect their nests. Naphthalene is also dangerous to mammals, including humans. Short-term exposure can result in liver damage or hemolytic anemia, a disorder of the red blood cells. On-going exposure can result in eye damage.

Exposure

Formosa subterranean termites becomes a problem when they nest in your home. They prefer nests that are underground above the water table, but can build secondary nests inside houses if the area is humid enough. Once they are inside, the naphthalene they produce can get into the air, leading to a daily exposure to the human residents. Naphthalene is only dangerous in large amounts and daily exposure can cause a build up of the chemical, increasing the risks to your health.
