Keeping clothes in cedar chests does not completely protect them from clothes moths. It may ward off adults but will not eliminate older larvae. You should always closely inspect your clothes before putting them away.
One way to handle moth infestation is to brush the infested clothes and fabric outdoors. This will dislodge the larvae and break the eggs. You can also expose the infested clothes to sub-zero temperatures for two days or to direct sunlight for 2 to 3 hours in the summer in order to kill off the larvae.
If you are dealing with a major infestation, we recommend applying Maheu&Maheu Insecticide Dust
or Maheu&Maheu Crawling Insect Killer
along baseboards, in closets, on carpets, and under furniture.
Pheromone traps are also helpful, employing sexual hormones to trap males, thus breaking the reproduction cycle. It is important to properly identify the moth, however, as the pheromones are species-specific.
