How to get rid of clothes moths
Clothes moth larvae chew straight-line holes in wool, cashmere, silk, and fur — usually in dark stored clothes you haven't worn in months. Adult moths don't eat fabric, but they lay the eggs that do. The fix is heat or freezing every wool item, vacuuming closets thoroughly, and pheromone traps to catch the adults still flying.
Tools
- ✓
- ✓Steam kills all moth life stages in dry-clean-only items you can't wash.
- ✓
Materials
- +Sticky pheromone traps for adult males. Use 1 per closet — they signal infestation level and break the breeding cycle.
- +Mild deterrent only. Cedar oil fades — sand the blocks twice a year if you keep using them.
- +After cleaning, store wool in sealed containers. Loose closet storage is what got you here.
- +Optional. Place inside a sealed garment bag with infested items for 2 weeks — kills all life stages without spraying clothes.
Steps

1
Identify clothes moths vs pantry moths
Clothes moths are tiny (~1/2 inch wingspan), buff/cream colored, and fly weakly in zigzags. They hate light and live in closets, drawers, and under furniture. Pantry moths fly straight, are bigger, and live in the kitchen — different fix.

2
Empty the closet completely
Take everything out. Inspect every wool, cashmere, silk, fur, and feather item for tiny silken tubes, frass (sand-like specks), or chewed holes. Bag infested items separately.

3
Heat-treat or freeze every wool item
Washable items: hot wash + high dry. Dry-clean-only items: garment-steam thoroughly, or seal in plastic and freeze at 0°F for 2 weeks. Either method kills eggs, larvae, and adults.
Tip: Don't skip items you're 'pretty sure' weren't infested — a single overlooked egg restarts the cycle. -
4
Vacuum the empty closet hard
Floor corners, baseboards, shelf cracks, the seams where carpet meets baseboard. Empty into a sealed bag outside immediately.

5
Hang pheromone traps
Place a Dr. Killigan's trap in each closet at chest height. Adult males stick and the trap tells you whether you still have a live infestation. Replace every 3 months.

6
Store clean wool in sealed bags
After laundering, store sweaters and wool blankets in airtight garment bags or plastic bins. Add cedar blocks for mild ongoing deterrence — but the sealed container is the actual fix.

Recheck at 4 weeks
If pheromone traps stay empty for 4 weeks straight, you're done. If they keep catching moths, repeat heat treatment — you missed an item.
