Moth Repellents and Traps

Moths fall into two general categories: clothes moths and outdoor moths. Clothes moths live in dark spaces, are not attracted to light, and eat fibers of woolen clothing. Common outdoor moths include the miller moth and the army cutworm moth. These moths are attracted to light, and are generally harmless to humans.

Types

Moth traps and repellents include naphthalene, or mothballs, for clothes moths, and light traps for common outdoor moths. Insecticide is generally ineffective for moth control. Bats are a natural predator for moths, and can help reduce the moth population around a house. Good housekeeping, laundering clothing, and eliminating dust help prevent infestations of clothing moths.

Effects

Mothballs contain naphthalene, a petroleum byproduct that repels some insects. This chemical is illegal in some areas, and should be used with great caution. It is toxic and can be absorbed through the skin by someone wearing clothing that has been stored with mothballs. The fumes are also toxic if inhaled often.

Function

A light trap consists of a bucket full of soapy water hung near a light source to attract outdoor moths. Moths fall into the water while flying around the light. A simple and efficient trap, this method requires caution while using water around electric equipment.
