The first question is which moth you have, because clothes moths and pantry moths share almost nothing beyond the name. For textiles we search folds, cuffs, carpet edges, and the floor under heavy furniture, and check roof voids for old bird or rodent nests. For food pests we go through every package in the affected cupboard, including sealed ones, then look at shelf corners and ceiling junctions where larvae crawl away to pupate. Treatment combines removal of infested material, thorough vacuuming, and targeted application to the cracks where larvae shelter, with pheromone traps to confirm the species and measure whether numbers are actually falling.
The single most important step. Clothes moth work searches textiles; pantry moth work searches every package in the cupboard. Treating the wrong one wastes time while the infestation continues.
Infested dry goods are discarded, sealed. Affected textiles are laundered hot, tumble dried, dry cleaned, or deep frozen for several days, depending on what the item can take.
Thorough vacuuming of carpet edges, wardrobe interiors, shelf runners, and hinge recesses, followed by immediate disposal of the vacuum contents, removes eggs and larvae directly.
Residual applied to shelf supports, wardrobe edges, carpet perimeters, and the voids where larvae pupate, chosen carefully where food or clothing is stored.
Species-specific traps catch adult males, which confirms which moth you have, shows where activity is concentrated, and gives a clear measure of whether numbers are falling.

Moth control divides cleanly in two, and getting the division right is most of the job. A moth in the wardrobe eating wool, cashmere, and silk is a completely different problem from a moth in the pantry laying eggs in flour, nuts, and pet food. They need different treatments, different searches, and different prevention. In both cases the adult moth you can see does no damage at all; it is the larvae, hidden in a cuff, a carpet edge, or the bottom of a cereal box, that cause every hole and every ruined bag of rice.
Clothes moths are small, plain, golden-buff, avoid light, and their larvae eat keratin in wool, silk, fur, and felt. Pantry moths such as the Indianmeal moth are larger with distinctive two-tone coppery wings, and their larvae live in flour, cereal, nuts, birdseed, and pet food. The treatments have almost nothing in common.
The larvae. Adult clothes moths have no functioning mouthparts and never feed. Killing the adults you see does nothing about the larvae already inside a folded sweater or under a carpet edge, which is where every hole comes from.
Nearly always from a product that was already infested when it was bought, most often birdseed, bulk grains, dried fruit, nuts, or dry pet food. Cleanliness has very little to do with it; sealed rigid storage and using bulk dry goods promptly have a great deal to do with it.
Only inside a sealed container where the vapour can build up. In an open wardrobe they mostly expose your household to the vapour without protecting the clothing. Sealed storage, laundering before storage, and dealing with existing larvae are far more effective.
Yes, for items that cannot be hot-washed. Seal the item in a bag, freeze it at minus 18 degrees or colder for at least a week, then remove and vacuum it. This is a common approach for wool, cashmere, and delicate heirloom textiles.
Pantry moth larvae often crawl well away from the food before pupating, so cocoons turn up in ceiling corners, shelf lips, and hinge recesses metres from the infested package. Finding them there means the source is still in the room and the cupboard needs a full check.
Pantry moth infestations usually resolve within four to six weeks once the source is found and removed, with pheromone traps confirming the drop. Clothes moth work can take longer, because larvae may be spread across several rooms and stored items, and follow-up is normally planned for six to eight weeks out.
The pest, the size of the property, how far activity has spread, and the number of visits all affect the price. A single wasp nest is a very different job from a bed bug programme across three rooms. Tell us what you have noticed and where your property is, and we will explain the proposed service and give you a quote before any treatment starts.

Identification, hiding places and life cycle help determine how to treat moths. These details explain what your technician looks for and why preparation and follow-up can matter.
A webbing clothes moth is small, about 6 to 8 mm long, plain golden-buff with no markings, and avoids light; you usually see it scuttling rather than flying to a lamp. A casemaking clothes moth is similar but slightly darker with faint spots. The Indianmeal moth, the common pantry moth, has a wingspan of roughly 16 to 20 mm and a very distinctive two-tone wing: pale grey at the base and coppery bronze on the outer half. If the moth flies to your lights in the evening it is far more likely to be a harmless outdoor moth that came in through a window.
Adults lay eggs directly on the food source. Eggs hatch into larvae, and it is the larval stage, lasting weeks to many months, that does all the feeding and all the damage. Larvae then spin a cocoon and emerge as adults, which live only a couple of weeks and, in the case of clothes moths, do not feed at all. In a warm house an Indianmeal moth can complete a generation in about six to eight weeks, and a single female can lay a few hundred eggs, so a small pantry problem escalates quickly.
Laid directly onto wool, fur, or dry food. Tiny and easily overlooked in a fold of fabric or a fold of packaging.
The only feeding stage and the cause of all damage. Clothes moth larvae hide in folds and carpet edges; pantry moth larvae live inside the food.
Spun into a cocoon, often well away from the food source. Cocoons in ceiling corners are a classic sign of a pantry moth infestation.
Does not feed in clothes moth species and exists only to reproduce. Killing the adults you see does nothing about the larvae already in the material.
Clothes moth larvae live in dark, undisturbed places against the material they eat: the folds of stored wool, under collars and inside cuffs, the carpet edge beneath a heavy wardrobe, the underside of upholstered furniture, felt in piano and speaker cabinets, and wool insulation. Pantry moth larvae live in the food itself, and they also crawl surprising distances to pupate, which is why cocoons show up in ceiling corners and on the top lip of a cupboard door far from the infested bag.
Clothes moth larvae digest keratin, the protein in wool, cashmere, silk, fur, feathers, felt, and hair. They do not eat cotton or synthetics, but they will attack blends and are strongly drawn to items soiled with sweat, body oils, or food, which is why the damage so often appears in a garment that was stored unwashed. Pantry moth larvae eat grain products, flour, cereal, nuts, dried fruit, chocolate, spices, birdseed, and dry pet food, and their larvae can chew through thin plastic bags and cardboard to get in.
Pantry moths almost always arrive in a product that was already infested when it was bought, frequently in birdseed, bulk grains, or pet food. Clothes moths arrive on second-hand textiles, rugs, vintage clothing, and taxidermy, and can also come from a bird or rodent nest in a roof space where feathers and fur sustain a population. Both spread within a building by larvae crawling and adults flying short distances between cupboards.
Both live indoors and are active all year in a heated Ontario building, though activity accelerates in warm weather. Clothes moth damage is most often discovered in autumn, when seasonal woollens come out of storage and the holes made over the summer are found. Pantry moth reports rise after bulk buying, and after birdseed and pet food are stored over winter.
Moths do not bite, sting, or transmit disease. Clothes moths cause irreversible damage to valuable and sentimental textiles: suits, coats, wool rugs, heirloom blankets, and upholstery. Pantry moths contaminate food with webbing, cast skins, and droppings, which means discarded stock at home and a genuine compliance problem for food businesses, bakeries, pet shops, and grocers.
Tineola bisselliella
6–8 mm
Plain golden-buff and light-shy. The main cause of holes in wool, cashmere, and silk in Ontario homes.
Tinea pellionella
6–9 mm
Larvae carry a portable silken case, which they drag across the fabric as they feed. Faint dark spots on the wings distinguish the adult.
Plodia interpunctella
16–20 mm wingspan
Two-tone wings, pale at the base and coppery outside. The usual pantry moth in kitchens, pet shops, and food storage.
Ephestia kuehniella
20–25 mm wingspan
Pale grey with darker zigzag markings. A stored-product pest of bakeries, mills, and commercial flour storage.
“The moths flying at my window are eating my clothes.”
Moths that fly toward light are almost always harmless outdoor species. Clothes moths avoid light and scuttle for cover. Look for the damage and the larvae, not the moths at the window.
“Mothballs will protect stored clothing.”
Mothballs are a registered pesticide that only works in a sealed container at a build-up of vapour, not in an open wardrobe. Used loosely they expose the household to the vapour without protecting the garments.
“Cedar blocks stop clothes moths.”
Cedar oil can deter some larvae when it is fresh and concentrated in a sealed chest, but blocks in an open wardrobe lose effect within months and do nothing about larvae already in the fabric.
“I threw out the infested flour, so it is finished.”
Larvae crawl away from the food to pupate, so cocoons are often in ceiling corners, hinge recesses, and the lip of the cupboard door. Clearing one package without cleaning those areas leaves the next generation in place.
