ANSWER: Fabric damage and cast skins of dermestid larvae (highly magnified)


There are about six insect groups that can cause damage to fabrics. Larvae of carpet beetles (Family: Dermestidae) and clothes moths(Family: Tingiidae) are major pests because fabrics/substances of animal origin are major components in their diet.

In the northern states east of the Rocky Mountains, damage to fabrics is more likely caused by dermestid beetles than clothes moths. Dermestid beetles are more resistant to cold temperatures and lower humidities of the northern states.

After damage to fabric is discovered, it may take some detective work to determine the culprit. The insect pest is usually no longer present when the damage is found.
