House Moth Identification — Which Moth Is in My House?
Small moths indoors usually mean one of two problems: clothes moths eating fabric, or pantry moths in your food. Upload a photo and our free AI tells you which — and whether it's a harmless visitor that flew in from outside.

How to Identify House Moths
Check these features before you rely on any single one — the combination is what confirms the ID.
Location is the fastest clue. Moths fluttering out of a closet, wardrobe, or drawer are clothes moths. Moths near the kitchen, pantry, or around stored grains and cereals are pantry moths. Big moths at the window at night usually just flew in from outside.
Both pest moths are small — about 1/2 inch or less. Webbing clothes moths are a plain buff-gold with no markings. Pantry moths (Indian meal moths) have a distinctive two-tone wing: pale cream near the body and coppery-bronze on the outer half.
Clothes moths are weak, reluctant fliers that prefer to scuttle and hide in dark corners — you'll often see them running rather than flying. Pantry moths fly in a characteristic zig-zag around the kitchen, especially at dusk.
The adults don't cause the damage — the caterpillar-like larvae do. Clothes moth larvae are small cream grubs in fabric; pantry moth larvae are pinkish caterpillars that leave silk webbing in food. Finding larvae confirms the infestation and its source.
Both leave silk. Clothes moths spin silken tubes or leave grazed, threadbare patches and small holes in wool and silk. Casemaking clothes moths drag a tiny silk case around with them. Pantry moths leave clumpy webbing that mats stored grains together.
Irregular holes and worn patches in wool sweaters, coats, carpets, or felt point to clothes moths. Webbed, clumping, or 'spun-together' flour, rice, cereal, nuts, dried fruit, or pet food points to pantry moths.
The Two House Moths — and What They're Not
Webbing Clothes Moth
Plain buff-gold, ~1/2 inch, weak flier that hides in dark closets. The larvae eat wool, cashmere, silk, felt, and fur, leaving small holes and threadbare patches. This is the classic 'moth holes in my sweater' culprit.
Casemaking Clothes Moth
Similar to the webbing clothes moth but slightly darker with faint dark spots on the wings, and its larva carries a small portable silk case. Same fabric damage, same treatment — deep cleaning and heat or freezing.
Indian Meal Moth (Pantry Moth)
The most common food moth: pale cream inner wing, coppery-bronze outer wing, flies zig-zag around the kitchen. Larvae infest flour, cereal, grains, nuts, dried fruit, chocolate, and pet food, leaving telltale webbing. The fix is finding and tossing the infested package.
Brown House Moth
A larger bronze-brown moth with dark speckles, common in homes but mostly a harmless scavenger of debris and occasionally stored products. Rarely the cause of significant fabric or food damage.
Carpet Beetle (not a moth)
Often blamed alongside moths for fabric holes. The adult is a tiny round mottled beetle, and the bristly larvae — not the adult — do the damage. If you see a beetle rather than a moth but still find fabric holes, it's likely carpet beetles.
Outdoor Moths That Flew In
Larger moths bumping around lights at night — like miller moths, underwings, or sphinx moths — are simply attracted indoors by light. They don't breed in your home, damage nothing, and can be gently released outside.
