The inside of the clothes moth trap is coated with a powerful glue and contains a sexually alluring pheromone that attracts male moths into the trap where they are caught by the adhesive, and die. This severely curtails the breeding opportunities of the moths, which then reduces the moth population. Even when moths are not obviously present, a trap will often catch a few moths, so giving an early warning of a new infestation by moths such as the Mediterranean flour moth, the Indian meal moth, the tobacco moth, and others.

Once unpacked it will continue to attract moths for 8 weeks.

In the event of an infestation, establish the number of all possible infestations. Then get any infested textiles (e.g. clothing, wool carpets, silk and furs) dry cleaned and vacuum their surrounding areas (e.g. cupboard, chest) thoroughly and wash these, if possible. Sensitive textiles can be packed into a plastic bag and left in the freezer for a week.
