Local pest control help is one call away.
Pest Control Services Nationwide Pest Control Services Nationwide Clothes moths are small gold-bronze moths about 6 to 8 millimeters across the wings, and they are the only common household moth whose larvae chew holes in wool, silk, fur, feathers, and leather. The adults you see flying out of a closet do not eat fabric. The damage comes from the white caterpillar-shaped larvae, which spin silk webbing or drag a small silk case while they tunnel through protein fibers. By the time the first hole shows up in a sweater, larvae have usually been feeding inside that closet for two to three months.
If you are seeing small gold-bronze moths that flutter weakly and prefer dark spaces, plus irregular holes in wool clothing or blankets with fine silk webbing or tiny silk tubes on the fabric, you almost certainly have clothes moths. This guide covers how to confirm the species, why soiled garments draw larvae more than clean ones, how freezing and laundering kill every life stage, and what professional treatment looks like when valuable items are at risk.

Clothes moth larvae feed in dark, undisturbed places on protein fibers. Adult moths avoid light and fly weakly, so countertop sightings are rare. The damage hides where you rarely look. Walk these zones with a flashlight and pull items out into the light:
If you find holes plus silk webbing or silk cases in two or more of these zones, you have an active infestation that has been running for at least one full generation. Larvae prefer soiled fibers carrying sweat, food stains, or body oils, so the dirty wool you put away at the end of last season is almost always where the population started. Damage to natural fibers is permanent. Catching the larvae before they spread from a guest closet into your primary wardrobe is what saves the most clothing.
Finding the holes is step one. Understanding what is keeping the larvae fed inside your closets is what stops the next generation. Clothes moths do not pick homes the way ants or roaches do. The larvae need three things: protein fibers like wool or silk, a dark undisturbed location, and ideally some surface soiling for extra nutrition. Homes that store wool, fur, or feather items for months or years without disturbance are the ones that build infestations.
What anchors them to your home:
A new infestation usually starts when a single mated female finds an unwashed wool sweater or a vintage rug in a dark closet. She lays 40 to 50 eggs directly on the fibers. Eggs hatch in one to two weeks, and the larvae feed for five to eight weeks before pupating. In a heated home, three or four overlapping generations run every year, so by the time you spot the first hole, eggs and larvae are likely scattered across multiple items in the same closet. Unlike carpet beetles, which spread throughout the home, clothes moth infestations concentrate in specific storage zones, that focus is both their weakness and the reason they go undetected for so long.
Find your scenario below. Each row reflects how a clothes moth population spreads through closets and storage, not a generic moth timeline.
| What You're Seeing | Severity | If Untreated | Next Step |
|---|---|---|---|
| Single hole in one wool garment plus one adult moth in the closet | Early | One generation runs every 2 to 3 months in a heated home, the next hatch is already inside the closet | Confirm the species, launder the affected item at 120°F or freeze it 72 hours at 0°F. Place a pheromone trap to monitor adult activity. |
| Multiple damaged garments in one closet plus visible silk webbing or cases on fabric | Moderate | The population has been active for at least one generation, damage spreads to additional items in the same closet within 2 to 3 months | Schedule a professional inspection this week. The whole closet needs comprehensive treatment, not just the visible items. |
| Damage across multiple closets, larvae visible, heirloom or valuable items at risk | High | Multiple generations are overlapping and the population has spread between storage zones, damage compounds weekly | Call a professional this week. Treatment needs all natural-fiber storage zones inspected, plus residual treatment in cracks and crevices. |
| Heavy infestation, irreplaceable items damaged, or family member with wool allergies | Urgent | Population is mature with continuous reproduction, irreplaceable items face active permanent loss every week | Call today. Ask about heat treatment for the closet or fumigation for valuable items, and coordinate with a textile conservator if heirlooms are affected. |
Damage to natural fibers is permanent and homeowners insurance treats it as preventable. If you are between two rows, treat the higher one as your situation.
Clothes moths run a full lifecycle in two to three months under typical home temperatures, and the larva is the only stage that damages fabric. Multiple overlapping generations stack inside heated homes, which is why a single closet can produce continuous activity year-round once the population is established. Understanding the four stages tells you exactly why cleaning visible garments is not enough.
Hatch in 4 to 10 days
Females glue 40 to 50 eggs directly onto wool, silk, fur, feathers, or other protein fibers. Eggs are about half a millimeter long and pale cream, so they look like dust and almost never get spotted during a casual inspection. This is the stage that survives most DIY treatments.
About 5 to 8 weeks in heated homes
Larvae are the damaging stage. A webbing moth larva spins silk webbing across the fabric and tunnels through it, leaving irregular holes. A case-bearing larva builds a small silk tube the size of a grain of rice and drags it along while feeding. Both are white caterpillars 6 to 10 millimeters long with a brown head. They always head to soiled fibers first.
About 8 to 10 days
The larva spins a tougher silk cocoon and transforms into an adult inside a fabric fold, a closet corner, or under a clothing tag. This is the stage that finishes the development cycle inside the storage zone where the larva fed.
Adults live 2 to 3 weeks and do not feed
Adults emerge ready to mate. The 6 to 8 millimeter gold-bronze moths avoid light, prefer to walk or fly weakly across fabric, and rarely leave the closet. Females start laying eggs within a day of mating. The adults do not damage fabric, but every adult flight signals another egg cycle is starting.
An established clothes moth population can run three to four overlapping generations every year inside a heated home, which is why activity persists across all seasons once the population is set. The damage compounds quietly inside dark closets and is permanent on the fibers it touches. Effective treatment has to kill all four stages together, surface-spraying the adults you see does nothing about the eggs and larvae hidden inside the wool.
Clothes moths live entirely indoors and stay active year-round in any heated structure. The seasonal pattern is less about outdoor weather and more about when homeowners rotate clothing in and out of storage, that is when most damage gets discovered.
Adult flights peak in spring as overwintering pupae emerge. Homeowners pulling stored winter wool out for cleaning often find the first holes now. Spring is the best window to start treatment because eggs from the previous fall are hatching and a focused intervention catches the larvae before they spread.
Population growth peaks. Warm temperatures speed up the lifecycle, so a generation that takes 3 months in winter can finish in 6 to 8 weeks during summer. Wool blankets and sweaters sitting in storage all season provide undisturbed feeding zones. Adult flights stay heavy.
Homeowners putting summer items into storage often introduce soiled garments that become feeding sites for the new generation. Fall is when most long-term damage starts, because soiled wool sweaters and blankets get sealed into closets and stay undisturbed for months.
Indoor heating keeps the population fully active even in cold climates. Adults emerge from pupae inside heated closets, mate, and lay eggs on stored wool. Outdoor weather has no effect on indoor populations, the lifecycle just keeps running.
Clothes moth work sits in an unusual middle ground. Light infestations caught early are absolutely a DIY job: launder or dry-clean affected wool items at 120°F or higher, freeze suspicious garments for 72 hours at 0°F, vacuum closet floors thoroughly and dispose of the bag outside, and place pheromone traps to monitor adult flight. That sequence kills every life stage on the items it touches and confirms whether the population is contained.
Professional help becomes worth the $250 to $700 cost when the infestation is heavy, when valuable or heirloom items are affected, or when DIY laundering has not stopped the activity after one full season. The most common DIY failure is missing eggs hidden in fabric folds, garment seams, or storage cracks, those eggs hatch over the following weeks and produce a new visible adult flight 2 to 3 months later, right after the homeowner thought the problem was solved.
A pro inspects every natural-fiber storage zone in the home, identifies whether you have webbing or case-bearing clothes moths so the right pheromone trap goes up, treats cracks and crevices in closets with appropriate residuals, and recommends heat treatment or fumigation for severe cases where individual garment processing is not practical. For irreplaceable heirloom textiles or museum-grade items, a specialist also coordinates with a textile conservator before any chemical treatment touches the fibers.
The hard truth is that damaged wool and silk cannot be repaired invisibly. The wait-and-see option costs nothing today and irreplaceable garments tomorrow. Catching the population while it is still concentrated in one closet is what protects the rest of the wardrobe.
Clothes moth treatment is not a single can of spray, it is closet-by-closet inspection plus targeted heat, freeze, or chemical work on the actual eggs and larvae. A specialist who handles fabric pests knows the visible adults are the smallest part of the problem. Here's what changes:
They Inspect Every Storage Zone The visit walks every closet, attic box, blanket chest, garment bag, and felt-lined drawer in the home. The goal is to identify every active feeding site before any product or heat treatment is applied, because skipping one storage zone means the population rebuilds from there.
They Identify the Species Webbing clothes moths and case-bearing clothes moths look similar as adults but feed differently. Pheromone traps are species-specific, so correct identification determines which lures get deployed and which storage zones get priority.
They Treat the Cracks and Crevices Larvae hide in baseboard cracks, closet corners, and the gaps under shelving. Residual treatment in these zones catches the larvae moving between feeding sites, which sprays on the visible garments will never reach.
They Plan for the Next Generation Eggs hidden in fabric folds and storage cracks can survive the first visit. Most programs include a follow-up at 30 to 60 days to confirm no new adult flight has started, and pheromone traps stay in place to monitor between visits.
Clothes moths are one of the few household pests where motivated DIY can actually finish the job on a small infestation. The split between DIY and pro work is mostly about scale and the value of the items at risk.

"Fumigation cleared stored product pests from our pantry and walls."
Indian meal moths and beetles had infested our pantry and spread into the wall cavities behind the kitchen. Standard treatments were not reaching the source. The provider recommended fumigation to eliminate larvae and adults in every hidden space. We cleared the home, the crew tented and treated, and clearance testing confirmed a complete knockdown.

Direct answers to what homeowners ask most about identification, fabric damage, and how to protect stored wool and silk.
Clothes moths are small (about 1/2 inch wingspan), gold to buff-colored moths that avoid light and flutter weakly when disturbed from dark closets, drawers, or storage areas, unlike most moths that fly toward light. The two common species are webbing clothes moths (which leave silken webbing and tubes on fabric surfaces) and casemaking clothes moths (whose larvae build portable cases from fabric fibers and droppings). Carpet beetle larvae, by contrast, are small, hairy, caterpillar-like grubs that leave bristly shed skins near damage sites. If you see tiny moths flying away from stored clothing in dark spaces, clothes moths are the likely culprit; if you find small, fuzzy shed skins, suspect carpet beetles.
Clothes moth larvae feed exclusively on materials containing keratin, theprotein found in animal fibers including wool, cashmere, silk, fur, feathers, and leather. They do not eat cotton, polyester, nylon, or other plant-based or synthetic fabrics, although they will chew through synthetic blends to reach animal-fiber components and may damage synthetic fabrics stained with food, perspiration, or body oils. Items most at risk include wool suits and sweaters, silk garments, fur coats, feather pillows, wool rugs, tapestries, and natural-bristle brushes. Larvae prefer to feed in dark, undisturbed areas, which is why stored seasonal clothing and heirloom textiles are particularly vulnerable.
There are two common indoor moth types with different targets. Clothes moths (webbing and casemaking) feed on wool, silk, fur, and feathers in closets. Pantry moths (Indian meal moths) infest stored grains, flour, cereal, nuts, and pet food. Both species are often introduced on infested items, secondhand clothing, bulk food purchases, or birdseed bags. Inspecting new items before storing them is key prevention.
Adult moths don't eat anything, it's their larvae that cause damage. Clothes moth larvae chew irregular holes in wool garments, cashmere, silk, and upholstered furniture. Pantry moth larvae contaminate food with webbing, frass, and shed skins. While neither species poses a health risk, the damage to clothing and food supplies is real and can be extensive if populations go unnoticed.
Most providers in our network can schedule an inspection within 24-48 hours. For urgent situations, likeactive structural damage or large colonies, same-week emergency service is often available. Response times depend on your location and the provider's current schedule.
Your provider inspects the property to identify the pest, locate nesting or entry points, and assess the scope of the problem. You get a clear explanation of what they found, what they recommend, and a written scope before any work begins.
Modern pest control products are designed to break down quickly after application and pose minimal risk to people and pets when applied correctly. Most providers ask you to keep kids and pets out of treated areas for 1 to 2 hours while the product dries, after which the area is generally safe again. Always confirm specific re-entry times with your provider, and let them know about pet birds, fish, or reptiles, since some treatments require extra precautions for those species.
Carpenter worms are large moth larvae that bore deep into the heartwood of living hardwood trees like oaks and elms. Their tunneling weakens trees over several years, creating hazards from falling limbs.
