What commonly indicates problems with a webbing clothes moth infestation?

Damage to clothing and fabrics is a significant indicator of webbing clothes moth infestation. These pests are known for their destructive feeding habits, particularly towards natural fibers such as wool, silk, and cotton. Adult moths lay their eggs on or near these materials, and once the larvae hatch, they begin to feed on the fibers. This feeding can result in visible holes or frayed edges in garments, upholstery, and other fabric items, serving as a direct sign of their presence and activity.

Other options do not accurately reflect the typical signs of a webbing clothes moth issue. Increased insect sightings in daylight are not typical for moths, as they are primarily nocturnal and more active during the night. Pollen accumulation on the floor is unrelated to moth infestations; it is more indicative of seasonal changes and plant activity rather than a pest problem. The presence of spider webs suggests the activity of spiders rather than moths, as webbing clothes moths do not produce webs for trapping prey like spiders do. This makes the first option the most relevant indicator of problems associated with webbing clothes moths.
