How to Identify: What Do Clothes Moths Look Like?
Clothes moths are small insects with golden or brown wings and a wingspan of 9 to 17 millimetres.
They can cause major damage to clothing and textiles. In this article, you will learn what clothes moths look like, from their size and colour to distinctive features such as the reddish hairs on their heads.
This guide will help you identify and manage these pests effectively.
Key Takeaways
- Clothes moth larvae feed on natural fibres, causing significant damage to garments, particularly in warm and undisturbed areas.
- Identifying adult clothes moths, primarily the Webbing and Case-Bearing types, is crucial as their presence indicates a need for immediate pest control measures.
- Regular inspections, the use of pheromone traps, and preventive measures like dry cleaning or storing clothing in airtight bins are effective strategies for managing and preventing clothes moth infestations.
What Are Clothes Moths?
Clothes moths feed on keratin fibres from wool, silk, and feathers. Their larvae can cause significant damage to clothing by leaving holes in garments. The common clothes moth is often encountered in homes, contributing to rising infestations.
These insects thrive in warm, undisturbed environments, often seeking dark corners of closets and storage bins to lay eggs. Seasonal and temperature changes influence their activity, with warmer conditions promoting their emergence and breeding.
Despite their destruction, clothes moths recycle nutrients in the ecosystem by breaking down keratin. Unlike pantry moths that roam, clothes moths stay in one place, making them easier to target during an infestation. Knowing these behaviours helps manage and prevent infestations.
How to Identifying Adult Clothes Moths
The everyday clothes moth is a small insect with golden wings typically held behind its body. Its wingspan is 12 to 17 millimetres, making it tiny but noticeable. A distinctive feature is the reddish hairs on its head.
The case-bearing clothes moth is another frequent household invader. It has brown forewings with a mottled appearance, often featuring one large dark spot and two smaller ones. With a wingspan of 9 to 16 millimetres, it is slightly smaller but equally destructive.
Adult clothes moths tend to crawl rather than fly, a telltale sign of an infestation. Spotting them in your home is an early warning to take action to protect your clothing and textiles.

Types of Clothes Moths
Two main types of clothes moths threaten your garments: the Webbing Clothes Moth and the Case-Bearing Clothes Moth. Both can cause significant damage to clothing, carpets, and other textiles.
Knowing the differences between these species can help you identify and manage an infestation more effectively.
Webbing Clothes Moth
The webbing clothes moth, or Tineola bisselliella, is a common household pest. These moths are about half an inch long with golden wings and a wingspan of 12 to 17 millimetres. Adults often fly shortly after pupation, indicating their presence.
Webbing clothes moth larvae feed on natural fibres like wool, fur, and silk, leaving behind holes and webbing. Adult webbing clothes moths can be recognised early, which is crucial to preventing extensive damage.
Case-Bearing Clothes Moth
Another common invader is the case-bearing clothes moth, which has a 9- to 16-millimetre wingspan. The adult moth has silver-grey, brown wings with a mottled appearance and black spots, which are characteristic of various moth species.
These moths have unique larvae with tunnel-like cases spun from silk and various materials. The larvae use these cases for protection while feeding on fabrics, causing significant damage.
The presence of these cases and the mottled appearance of adult moths can help identify a case-bearing clothes moth infestation.
Clothes Moth Larvae
Clothes moth larvae are the primary cause of textile damage. They can grow up to 13 millimetres long and are typically white with hardened brown head capsules. Webbing clothes moth larvae have a creamy-white appearance and can grow up to half an inch long.
These larvae feed on proteins in natural fibres, leaving trails on woollen fabrics and causing fur to lose hair. They prefer low-light environments and are commonly found in dirty fabrics, where they create silk tunnels for protection. Silken tubes or casings are clear indicators of active larvae, especially from case-bearing clothes moths.
Early recognition of clothes moth larvae can prevent extensive damage and costly repairs. Regular inspections and prompt action are crucial to managing these pests.
Life Cycle of Clothes Moths
The life cycle of clothes moths involves several stages. Clothes moth eggs typically hatch within 4 to 10 days during the summer, but this period can extend up to 21 days, depending on environmental conditions.
Once hatched, the larvae feed on natural fibres for a few weeks up to two years if conditions are unfavourable. After the larval stage, they spin cocoons and enter pupation, lasting about 10 to 50 days.
During pupation, they transform into adult moths, ready to mate and lay eggs within one to two days of emerging. Understanding this lifecycle is crucial for effective prevention and control.
Signs of a Clothes Moth Infestation
Early detection of a clothes moth infestation can save your wardrobe from extensive damage. Common signs include holes in clothing, especially around cuffs, collars, or seams, and the presence of silken cases and faecal pellets left by larvae.
Clothes moth larvae are often mistaken for small grubs and can be found in clothing or fabric. Silken webs or tubes left by clothes moth larvae can also indicate an active infestation.
Regular inspections of closets and drawer spaces are important for early detection and management of moth infestations. Knowing these signs helps you proactively protect your clothing and prevent further damage.
Tools for Detecting Clothes Moths
Effective tools for detecting clothes moths are essential for preventing severe infestations. Pheromone traps and visual inspections help monitor and identify the presence of clothes moth traps in your home.

Pheromone Traps
Pheromone traps attract and capture male moths before they can reproduce by emitting a scent that lures them, preventing them from mating with females. Moth traps help in this process by reducing the population of male moths.
Replace pheromone lures every six weeks to maintain trap effectiveness. These traps are particularly useful for capturing male webbing clothes moths, aiding population control and reducing infestation risk.
Visual Inspections
Thorough visual inspections are another effective method for detecting clothes moth infestations. Moth eggs are very small, around 0.5 millimetres, and typically laid in hidden areas within clothing or fabric, making them difficult to see.
During inspections, look for cream-coloured larvae up to 1.5 centimetres long, often nestled in fabrics, creating holes or webbing. Inspect areas with high humidity or stored fabrics, such as closets, attics, and basements, for signs of moth activity and damage.
Regular inspections help catch infestations early and take appropriate action.
Prevention and Control Measures
Preventing and controlling clothes moth infestations requires multiple methods. Dry cleaning effectively eliminates moth larvae from clothing. Freezing items at 0 °F for at least 72 hours can also kill moth eggs and larvae.
Natural substances like cedar oil and dried lavender can prevent clothes moth infestations, as strong-scented essential oils repel adult moths. Regular vacuuming and inspecting clothes can make breeding sites uncomfortable, and storing wool or fur garments in airtight plastic bins can keep moths at bay.
Eliminating the source of an infestation is crucial for effective control. Regularly monitor and clean storage areas and use traps to decrease the moth population by preventing mating. These measures protect your clothing and maintain a moth-free home.
