There are a few types of clothes moths that can eat polyester. The most common type is the cottony maple tussock moth.

This moth prefers to eat natural fibers such as cotton, wool, and silk, but it will also eat synthetic fibers such as polyester. Polyester is a popular material used in clothing because it is solid, durable, and susceptible to insect damage.

The other one that can eat polyester is the casemated cloth and silk moth. This moth prefers to feed on animal hair and wool but will also consume polyester fabrics if available.

Both of these moths produce webbing that can damage polyester fabric surfaces.

There are two ways they get into your clothes: getting caught in the fabric while flying or getting stuck in tiny crevices.

The first way is more common, as they fly around more. If you have a lot of polyester clothing, though, it’s likely that you’ll have a problem with this type of moth.

Polyester is a synthetic fiber that’s very soft and pliable, making it perfect for the moths’ feeding habits. These creatures feed on the proteins and other nutrients found in animal skin and hair, so if you have a lot of polyester clothing, you’re likely to see them congregate around these areas.

The second way they can get into your clothes is through tiny holes and crevices. These moths are small, so they can easily squeeze through any opening. They often prefer to lay their eggs in these areas, hatching them into larvae that feed on the fabric.
