THE FIELD GUIDE

Clothes Moths, Done Properly

A complete, step-by-step guide to treating clothes moths the way they should be treated, from someone who is obsessive about them. Every garment screened, every probe logged, every stage of the life cycle accounted for.

Written by Jorge Bedoya, ACE · NYSDEC #15140 · New York Exterminating, Midwood, Brooklyn

Quick answer: Clothes moths are treated properly by identifying the species first, screening every item by fabric and label, heating items to a probe-verified core temperature (or freezing the ones heat would harm), steaming and HEPA-vacuuming the closets and rugs where larvae hide, treating the structure, and monitoring for months. This guide by Jorge Bedoya, ACE, of New York Exterminating walks through each step, what can and cannot go in a heat chamber, and why.

What the chamber looks likePHOTO COURTESY OF ZAPPBUG

ZappBug Room heat chamber with shelves of belongings inside, shown to give a sense of scale

For scale: one full chamber holds shelves of belongings in a single cycle. We build ours inside your home, in the room where the clothes already are.

1 The method, in pictures

NYE Private Client

Estate wardrobes on Long Island and in Westchester are handled under our appointment-only Private Client moth program: every garment assessed by an ACE, processed on site so nothing leaves your home, and documented in a written report. Programs from $3,000 in Manhasset, Old Westbury, the Gold Coast, Scarsdale and Rye and Purchase.

Most pages describe moth treatment in the abstract. Here is every stage as we actually run it, in a real Brooklyn brownstone.

Inspect, identify and screen

An ACE inspects every garment by hand under a work light, checking folds, seams and linings for casings, webbing and frass, and sorts each piece before anything enters a chamber.

Technician inspecting a wool garment in a dark closet under a work light — Hands-on inspection of a wool garment, checking for casings left by earlier activity.

We build the heat chamber in your home

Frame, insulated liner and heater go up in the room where your clothes already are. Garments hang spaced on rails, up to four rows of 15 pieces, so hot air reaches every item.

Verified, not guessed: the probe

A probe sits in the most insulated spot of the load. The hold clock starts only when that spot reaches target: 30 minutes for adults and larvae, 1 hour for eggs.

Probe thermometer reading 127.2 degrees Fahrenheit in the most insulated part of the chamber — The proof: 127.2°F at the slowest spot. The clock starts here.

Deep steam on the places moths hide

While the chamber runs, technicians steam seams, joints and the tops of curtains, where fabric gathers and females tend to lay eggs.

Residual, larvicide and adult knockdown

Residual and long-acting larvicide go on the closet structure, and a base-oil aerosol knocks down adults in voids and edges, only after the chamber has cooled.

Contained dichlorvos vapor, only when indicated

For items heat cannot take, a labeled strip goes inside a sealed trunk or bin, clear of the fabric, handled by a licensed applicator.

Month-one check and written report

Traps go out at day 30. You get a written report with photos and logs, and the six-month follow-up window starts counting.

Tip: shoot the underside of collars, the closet floor corners and one trap if you have it. Bird’s nest moths are common in traps and are not clothes moths.

3 Why October through spring is moth season in NYC

Heated New York buildings keep clothes moths active all winter, and the calendar works against you: summer clothes get packed away, winter wool comes out of storage, and anything that went away unwashed carries eggs with it. Webbing clothes moths can be found year-round in a warmed building, and larvae damage speeds up with warmth.

Figure 1. The NYC moth calendarCONCEPT, not measured data

Seasonal rhythm of storing and unpacking natural-fiber clothing in heated NYC apartments.

4 Brownstones, pre-war co-ops and rentals: what is different in New York

New York moth jobs are rarely a single closet. Pre-war buildings concentrate exactly what larvae eat: stored seasonal wool, antique and Oriental rugs, natural-fiber upholstery and rooms that stay shut for months. Reservoirs often sit outside your unit: wool carpet and padding next door, pet hair and lint in vents and voids, pigeon nests on air-conditioner units that fill traps with look-alike moths.

Brownstones and townhouses: multi-floor closets, cedar rooms, stored furs and rugs; we plan chamber placement and stair carries up front.
Co-ops and condos: board and managing-agent rules, elevator reservations, work-hour limits and alarm notification; we handle the paperwork with you.
Rentals: shared walls and vents mean a source next door can reseed you; we document findings so your landlord has a record.

5 How clothes moths live, and why traps mislead

Only larvae eat fabric. That is why the stage that matters is the one you rarely see.

Figure 2. Clothes moth life cycle, in daysSOURCED: Rutgers NJAES FS1182 (webbing clothes moth)

Eggs: 40–50 per female, glued to fibers. The long, variable larval stage is why treatment has to cover months, not days.

6 How heat actually kills them

Insects die from a combination of temperature and time. Eggs tolerate the most heat of any stage, so the hold is designed around eggs.

Figure 3. Heat chamber cycle: why the probe, not the timer, decidesILLUSTRATIVE CURVESOURCED threshold lines

AirCore of slowest item

Curve shape is a teaching sketch, not measured data; real jobs use the logged probe curve. Threshold lines: ~120°F for 30–60+ min (field guide citing Ebling; eggs need the longer end), 41°C for 4 h all stages (Bull. Entomol. Res.). NYE standard hold, counted from the moment the slowest probe reaches target: 30 minutes for adults and larvae, 1 hour for eggs, inside a full cycle of several hours.

Figure 4. Who survives the longest at lethal heat?CONCEPT DIAGRAM

Relative heat tolerance, not minutes: adults and larvae are the easiest to kill, pupae more tolerant, and eggs the most tolerant of all, so the hold is designed around eggs.

Pick an item to see its default category.

The care label and an in-person inspection always decide. This is a first filter, not a promise.

9 Brand-by-brand screening guide

People ask about brands because a brand predicts materials, linings and adhesives. A brand does not predict whether a specific garment tolerates heat: that is decided by the fabric, the construction and the care label in your hands.

Figure 7. Brand and category screening tableNYE SCREENING GUIDANCE

Brands	What they make	NYE default	Why
Canada Goose, Moncler, Patagonia, The North Face, Arc’teryx	Down or synthetic fill in coated nylon shells; some have real fur trim and taped seams	ORANGE	Patagonia’s own care page says machine dry on no to low heat and warns high heat can ruin down. A chamber hold at 120°F core is outside that. Fur trim is a separate decline. Default: freeze, or heat only with the maker’s tolerance in hand.
Loro Piana, Brunello Cucinelli, Max Mara, Hermès, The Row	Fine cashmere, vicuña, silk blends, fine knits	ORANGE	Labels typically read dry clean or hand wash cool; care sources agree to avoid heat. These are the garments moths prefer and the ones with the most to lose. Default: professional freezing or specialist cleaning.
Uniqlo, J.Crew, Everlane, Gap (cashmere and merino basics)	Mass-market merino and cashmere knits	YELLOW	Often wash-cool labels. Chamber possible after a probe-controlled test load. Garment must be dry.
Brooks Brothers, Hugo Boss, Ralph Lauren, Theory (tailoring)	Wool suits and jackets, often canvassed with fused interlining and glued collars	YELLOW	Fusible interlinings and adhesives are the risk. Accept after inspection; verify the core by probe.
Levi’s, Wrangler, Lee, Carhartt, Dickies	Cotton denim, canvas, duck	GREEN	Durable cotton; rivets and buttons are fine. Check for rubber or vinyl patches and leather labels.
Hanes, Fruit of the Loom, Champion, Gap basics	Cotton and cotton-poly knits, fleece	GREEN	Routine load. Screen-printed or heat-transfer graphics can crack; photograph first.
Nike, Adidas, Lululemon, Under Armour, Gymshark	Polyester, nylon, elastane, heat-transfer logos	YELLOW	Elastane can degrade and prints can lift. Pure synthetics are rarely moth food; ask why they are in the load.
Nike, Adidas, New Balance, Hoka, Allbirds, Converse (footwear)	Foam midsoles, glued soles, mesh uppers	ORANGE	Glue and foam deform at chamber temperatures. Shoes are the item we most often decline.
Coach, Louis Vuitton, Gucci, Prada, Hermès, Chanel (bags, leather goods)	Leather, coated canvas, lacquered edges, glued handles	RED / ORANGE	Finish change and adhesive failure are irreversible. Alternative: inspection, cold treatment or specialist cleaning.
Burberry, Barbour (trench and waxed coats)	Cotton gabardine, waxed cotton, bonded linings	ORANGE	Wax melts and migrates; bonded linings delaminate. Waxed coats are a hard decline.
Pendleton, Faribault, Woolrich (blankets, wool outerwear)	Heavy wool blankets and shirts	YELLOW	Dense wool is what moths eat and tolerates heat reasonably, but thick piles need a core probe, not an air reading.
Persian, Oriental and silk rugs (any maker)	Wool or silk pile, natural dyes, jute or cotton foundations	ORANGE	Natural dyes and backings are unstable. Specialist conservation or cold treatment; heat only after a dye test.
Eileen Fisher, Vince, Madewell, Zara, H&M (mixed fashion)	Viscose, rayon, acetate, linen blends, glued trims	YELLOW	Viscose and acetate are heat sensitive. If the label says low iron, we do not run a 120°F core hold.

The care label always outranks this table. A “do not tumble dry” label means not a chamber candidate, whatever the brand.

10 Fabric and material guide

Larvae eat animal fibers (keratin), so the most valuable closet contents are also the most heat-sensitive.

14 Fire alarms, detectors and sprinklers: the pre-job plan

A heat job in a New York building is also a fire-safety job. Heat, steam, HEPA dust and oil-based aerosol mist can each trip a detector, and a false alarm in an occupied building brings the fire department.

Figure 13. Fire-safety checklist for a heat treatment jobNYE PRACTICE

Step	Why it matters
Walk the unit and corridor first: locate smoke, heat and sprinkler heads near the chamber and the steam work.	Placement decides whether a detector can see chamber air, steam or aerosol.
Tell the building before the day: super, management and the alarm company.	NYC rules require a logged record when an alarm system is taken offline, who was notified and when it is restored, plus notice to occupants. Impairment is the building’s regulated process.
Never cover or disable a detector yourself unless the building’s authorized person approves.	Covering detectors without authorization is an impairment and may need a fire watch.
Place the chamber away from detectors, sprinkler heads and curtains, with clear space all round.	Chamber air at 120°F and above and heater exhaust can trip heat detectors and fusible links.
Keep the room ventilated: a ZappBug heater may alarm and shut off if the surrounding room is above about 99°F.	The unit has its own over-temperature safety alarm; ventilation keeps the room within its limit.
Keep steam and aerosol work away from detectors and time it with the building notice.	Steam and oil mist look like smoke to photoelectric detectors.
Restore and test: confirm the system is back, close the log, tell occupants.	Closes the legal record and prevents a silent impairment.

16 Base-oil aerosol knockdown for adults

Flying adults are mostly males that never eat fabric, but they mark the population and mate. A base-oil aerosol applied to closet voids, rug edges and baseboards knocks adults down on contact and gives a fast first reduction while heat and residuals do the deeper work.

Rule	Reason
Applied only after the chamber has cooled and loads are out	Oil-based aerosol and vapor are a fire hazard near heat
Applied to structure (voids, baseboards, closet frames, rug edges), not onto garments	Label sites govern; no residue on fabric
Ventilate, and account for detectors	Aerosol mist can trip photoelectric smoke detectors
Adults only; not an egg or larva treatment	Heat, steam, HEPA, residuals and larvicide handle other stages
Not combined with a vapor strip in the same space on the same day	Label conflicts and product-on-product exposure

25 Myths, questions people ask, and troubleshooting

Claim	Reality
“Mothballs or cedar kill moths.”	Mothballs need a sealed airtight space; cedar repels some adults but does not kill eggs or larvae.
“Dry cleaning solves it.”	Cleaning kills active stages but does not protect the next hatch; heat or cold plus structure work does.
“I still see a moth after treatment, so it failed.”	Pupae keep emerging for weeks. The month-one trap count is the meaningful reading.
“A fuller trap means a worse infestation.”	Traps often catch bird’s nest moths drawn by the same lure.
“Freeze it for a week.”	Rutgers says two weeks; a lab model for eggs shows about 15 h at −20°C.
“Any heat kills eggs fast.”	Eggs are the most heat-tolerant stage; holds must be designed around them.

26 Glossary and sources

Core temperature: measured inside the slowest-heating item. Hold: verified time at or above target. Impairment: a fire-alarm system taken out of service. Residual: a treatment that keeps working on surfaces after application. DWR: durable water-repellent coating.

28 Clothes moth heat treatment FAQ

How does clothes moth heat treatment work?

A chamber is built around the items, heated air circulates through spaced garments, and a probe placed in the slowest-heating item reads the core temperature. New York Exterminating counts the hold from the moment that slowest probe reaches target: 30 minutes for adults and larvae and 1 hour for eggs, which are the most heat-tolerant stage. The hold sits inside a full cycle of several hours.

Do you really treat the clothes inside my home?

Yes. We set up the heat chamber in your apartment or house, treat your garments where they hang, and steam, HEPA-vacuum and treat closets, baseboards and rugs during the same visit. Nothing goes to a dry cleaner, a plant or a storage unit.

How long does a clothes moth treatment take, and can I stay home?

A large job runs about ten hours, because the heat cycle, steaming, HEPA vacuuming and structure treatment run in parallel. You can stay in other rooms, but people and pets stay out of the work area until treated surfaces are dry and aired, as the product labels require.

What cannot go into the heat chamber?

Aerosol cans, lighters, fuels, candles, lipstick and cosmetics, vinyl records, photographs, batteries and electronics, medications, glued-sole shoes, foam, vinyl, and anything alive or wet stay out. Fur, leather, fine silk and fine cashmere are declined by default and routed to freezing or a specialist. Sections 9 to 11 list brands, materials and hard stops.

Will heat damage my wool or cashmere?

Not if the piece is screened first. We read the fabric, trims and care label, and we probe inside the item. Mass-market merino and cashmere can go in after a controlled test load when dry, while fine luxury cashmere defaults to freezing or specialist cleaning because its labels say to avoid heat.

Do I need to dry clean or wash everything before you arrive?

No. You do not need to dry clean the whole closet, and many pieces cannot be dry cleaned anyway. Keep washed and unwashed items apart, do not shake garments out, and bag them where they hang. Soiled clothing is more attractive to larvae, so tell us which pieces are worn and unwashed.

Why do I still see moths after treatment?

Pupae that were already sealed in cocoons keep emerging for weeks, so a few moths in the first three weeks is expected and is not by itself a failed treatment. Traps go out at about day 30, and that count is the meaningful reading.

Is heat better than freezing for clothes moths?

They are different tools. Rutgers recommends 0 degrees F for two weeks for freezing, which suits items heat would harm, while a heat chamber treats a whole load in one day. We choose the method per item and use both when a job needs it.

Is there a follow-up if moths come back?

Moth activity can return if a source was missed, so a month-one trap check is part of the process. Follow-up visits within six months are 50% off, and an ACE inspects first to find the source rather than assuming the first treatment failed.

How much does professional clothes moth treatment cost in NYC?

Treatment ranges from $450 to $2,500, quoted after inspection. Price depends on the volume of garments, the number of areas, how established the activity is, delicate materials, and rugs or upholstery. Financing over 3, 6, 12 or 24 months is available.

Are carpet beetles the same as clothes moths?

No, but they are often found together and damage the same fibers. We identify the species first and treat carpet beetles in the same visit when they are present. Our carpet beetle versus clothes moth guide shows how to tell them apart.

Do you use dichlorvos (Nuvan) strips?

Only when indicated, and never with heat. A licensed applicator places a labeled strip inside a sealed trunk, bin or bag with the strip kept clear of fabric, for items heat cannot take. Silk, leather, metal hardware, jewelry, foam and glued items never go in with a strip.

What about fire alarms and smoke detectors in my building?

Heat, steam and oil-based mist can each trip a detector, so we plan before the day. You tell the super and management, we place the chamber away from detectors and sprinkler heads, and any alarm impairment goes through the building’s authorized process. We never cover a detector ourselves.

Do you treat clothes moths in Brooklyn brownstones, co-ops and rentals?

Yes. We serve all five boroughs plus Nassau and Westchester from our Midwood, Brooklyn office, and pre-war buildings with stored wool, antique rugs and shut rooms are where we do the most chamber work. Every job ends with a written treatment report you can give your building or insurer.
