San Marcos Moth Infestation — Why Species Identification Changes Everything
The two most common pest moth species in San Marcos homes are the webbing clothes moth and the Indian meal moth, which infests stored food. They have different habits, different food sources, and require different treatment approaches — correct identification is the first step.
Clothes moths are attracted to natural protein fibers — wool, cashmere, silk, fur, leather, and feathers. They avoid light, preferring undisturbed dark areas like the back of wardrobes and stored textiles. Damage is caused not by the adult moth but by the larvae, which feed on the fibers over weeks to months.
Adult Moths Are Not the Problem
Adult moths do not feed on fabrics or food — they do not have functional mouthparts. All damage is caused by the larvae. Seeing adult moths in your home means larvae are already active somewhere in the property. Treatment must target larvae and eggs in their harborage areas.
Indian Meal Moths in San Marcos — What They Target and How They Spread
Pantry moth infestations in San Marcos homes almost always begin with a single purchased item that was already infested before it arrived. Eggs or larvae inside flour bags, cereal boxes, nut packets, or spice jars are undetectable at the point of purchase. Once in the pantry, larvae spread between items via their characteristic silken webbing, contaminating open containers and creating infested clusters across the entire shelf.
