Do Clothes Moth Eat Pet Hair?

Clothes moth larvae are opportunistic feeders that primarily target natural fibers rich in keratin—namely wool, silk, fur, and feathers. While their main attraction is to these nutrient-dense fibers, they can indeed chew on pet hair, especially when it’s soiled with oils or mixed with dander. In environments where pet hair accumulates on clothing or upholstery, the extra protein and natural residues can make it an appealing supplemental food source for the larvae.

Pet owners are fully aware that pet hair and dander (skin) will collect everywhere, especially edges, under furniture, on soft furnishings and in vents and ducts.

It’s important to note that adult clothes moths do not feed; they exist solely for reproduction. It’s the larvae that cause the damage. Generally, a well-maintained home with regular cleaning and proper storage of textiles can help reduce the buildup of pet hair and residual oils, thereby lowering the risk of an infestation. Vacuuming, washing fabric surfaces, and using lint rollers to remove pet hair can be effective preventive measures. Use a vacuum cleaner with a hepa bag. Dispose of bags outside.
