House Moth Identification
Finding a moth in your home is going to raise a lot of questions. How did it get here? Is the moth after your clothing or is it harmless? You might even wonder if finding a single moth is worthy of concern. Even one adult moth raises the chance of an infestation, so you need to know what to look for and how to protect your home. The first step? Knowing how to identify the moths in your home.
What are Moths?
It is believed that there are at least over 160,000 types of moths that we know of, but there are more species that haven’t even been researched yet. While moths are closely related to butterflies, their food sources are different. Compared to the vibrant colors of butterflies, the majority of moths that you see in your home are neutral colors, like gray, brown, white, and cream.
Moths rest their wings flat against their back, which is one defining feature that can help you with household moth identification.
Types of House Moths
When people talk about household moth identification, they are typically talking about two categories: Pantry Moths and Clothes Moths. The species of moths in each category have similar appetites, but their behavior, appearance and lifespan differ slightly from 30 - 45 days.
Pantry Moths
As you may be able to guess, a Pantry Moth is found in the pantry! They thrive anywhere where unprotected grains are found, including rice, cereal, dry pet food, crackers, and similar goods. They may even target nuts, dried fruit, spices, and chocolate.
Generally, Pantry Moth Larvae leave behind silken webbing and excrement, and will be seen squirming around inside bags of flour or containers. There are four common types of pantry moths to keep an eye out for:
Mediterranean Pantry Moth
Protect your flour. The Mediterranean Pantry Moth is a highly damaging moth. While these moths tend to go after flour, they will also lay eggs near breakfast cereal, dried grain, bran, and oatmeal. An infestation can be identified by the moth larvae's silken webbing that causes the food source and moth larvae to clump together. Consider placing pantry moth traps in vulnerable areas.
Mediterranean Pantry Moths are a gray color with black zigzags on their wings. The hind legs are an off-white color. When fully grown, these moths are about 23mm long. They also have a resting pose where the forelegs are extended above the head, so the body slopes. No other pantry moth does this.
Larvae can be white or slightly pink and have a dark head. Some have black dots on the body.
Moth prevention products like moth pheromone traps can help monitor and reduce infestations over time.
Brown House Moth
The Brown House Moth (Hofmannophila pseudopretella) is thought to have originated in Asia. While falling into the pantry moth category, Brown House Moths will be found throughout the home. An adult Brown House Moth is about 8-14mm long and has a 15-26mm wide wingspan. The wings are usually shades of brown mottled with darker spots on the wings and body.
You can find the larvae in the pantry, carpets, and clothing. A larva is about 6mm long and has an off-white body with a light brown head. They feed on dried food, flour, rice, oatmeal, potatoes, bread, and even natural fibers woven into clothing and other textiles.
For this reason, both carpet moth traps and clothes moth traps should be considered essential moth prevention products.
White Shouldered House Moth
Attracted to light, the White Shouldered House Moth (Endrosis sarcitrella) is found fluttering around light bulbs within homes, factories, and other buildings. Warmer temperatures and central heating will keep adult moths active throughout the year, and the larvae are omnivorous. Moths will lay their eggs on a food source suitable for their larvae. For example protein-based fibers such as wool, fur, feathers,leather and suede. They also eat anything with grains, such as bran cereal, flour, seed, dried beans, legumes, and oatmeal.
The defining feature of White Shouldered House Moths is the white head and white patch on the upper shoulders. They have long brown antennae, a light brown base with some fringe on the wings, and darker mottling throughout. The ends of the wings are also tapered. Adults are between 6.3-10.5 mm long, with females being larger; the wingspan is 10-25mm. Their larvae have red heads and cream bodies. Consider moth prevention moth traps in rooms where light attracts them.
Indian Meal Moth
Many people seeking out house moth identification are looking for information on the Indian Meal Moth (Plodia interpunctella), also known as Flour Moths or Pantry Moths. These moths have a unique appearance, including a small bronze colored head, bronze shoulders, and a patch of light brown on the upper body. The ends of the two-tone wings are darker, with a slight fringe.
Adult Indian Meal Moths grow about 8-10mm long and have a wingspan of 16-20mm wide. The larva has a brownish head and cream colored body. Adult Meal Moths prefer dark, cool places and will lay their eggs anywhere they can find unprotected cereal, dried fruits, vegetables, bread, flour, pasta, rice, nuts, and even chocolate! To help eliminate them, use pantry moth traps as part of your moth prevention plan.
Evidence of an Indian Meal Moth infestation comes in the form of the larvae wriggling within food, or the discovery of food bound together by webbing.

Clothes Moths
Unlike Pantry Moths, Clothes Moths target protein-based fibers such as furs, silk, wool, and linen. You will find these moths in dark undisturbed spaces such as your attic, closets or basement.
Signs of a clothes moth infestation include:
- Silken strands /webbing
- Excrement with the appearance of small grains of sand
- Holes in clothing
- Long, cylindrical silk cases, sometimes occupied by larvae
Webbing Clothes Moth or Common Clothes Moth
One of the most commonly confronted and damaging in this list is the Webbing Clothes Moth (Tineola bisselliella). These are small moths, reaching about 6-7mm in length when mature. Characterized by white antennae, a fuzzy brown head, and fringed white wings, they often crawl around rather than fly.
The larvae are longer, about 10mm long and infest a wide range of materials made from natural fibers; including your knitwear, carpets, rugs and other textiles. Combat them using clothes moth pheromone traps, carpet moth traps, or full carpet moth treatment kits for stubborn infestations.
Case-Bearing Clothes Moth
Rarer than the Webbing Clothes Moth, the Case-Bearing Clothes Moth (Tinea Pellionella) has a larva that fabricates a tube of silk fibers and food debris around itself that adheres to their bodies as they eat. The tube looks a bit like a grain of rice, but if you look closely, there will be the brownish-red head of a larva protruding out of one end.
Case-Bearing Clothes Moth adults are darker than the common clothes moth, 6-7mm long, and have a trio of spots on their wings.

Usually, these moths measure between 8 and 14 mm long and have wingspans of 15 to 26 mm. The larvae of Brown House Moths are slightly smaller than the larvae of other species and tend to be an off-white color with darker-colored heads.
How to identify Brown House Moths?
With Brown House Moth identification, the main things to keep in mind are appearance and location. These moths are brown, brownish-gray, or bronze-brown in color and are weak flyers. The ravenous larvae of these moths can be found eating keratin or cereal proteins. This may include wool, leather, fur, grains, or other exposed dry foods. If you have larvae or adult moths infesting your pantry, closet, or cupboards, Brown House moths may be to blame. Try using clothes moth traps or pantry moth traps to help identify and manage them.
What do House Moth cocoons look like?
With house moth cocoon identification, you will be looking for long, oval-shaped casings. These casings can be found in garages, closets, drawers, crevices, beneath furniture, in food storage bins, and more. Usually, these casings are a tan or off-white color. However, they can also be brown or light yellow.
How to identify Clothes Moth Larvae?
Clothes Moth larvae identification involves carefully inspecting garments, furniture, or other materials for the presence of small brownish or yellowish worms. Usually, These larvae are shiny and white in color with heads that are a darker shade, ranging from tan to brown. Webbing Clothes Moth Larvae spin web-like cocoons as they feed. Case Bearing Clothes Moth Larvae may leave oblong or cylindrical casings behind as they grow.
Clothes Moth Larvae will tunnel through items that contain animal based fibers such as leather, silk, cashmere, wool, feathers, and so on while feeding. The presence of dead larvae or adult moths is another sign that these pest moths may be lurking nearby.
Do I need to hire an expert for moth pest identification?
If you realize that your home is infested by moths, hiring an exterminator for help may seem like the best option. For serious infestations, a professional pest control service may indeed be the best possible solution. However, oftentimes, homeowners find that they can remove these pests without the help of professionals. The process involves identifying the most heavily infested areas, thoroughly cleaning, and implementing future preventative measures such as pheromone moth traps. If you do discover that your moth infestation is larger than first anticipated you may like to read our Clothes Moths Kit Guide and Pantry Moths Kit Guide for information on how to use chemical products in line with our Traps.
What kind of moths come into your house?
The most common types of moths that infest homes are Clothes Moths and Pantry Moths. There are many subspecies of both of these moths. Pantry Moths tend to infest pantry and cupboard spaces and lay eggs that hatch into larvae which eat grains, cereals, flour, and other dry goods. Clothes Moth Larvae feed on fabrics or materials that contain the protein keratin which is found in animal based fibers. This may include wool, silk, cashmere, leather, feathers, and more.
Early use of clothes moth traps and pantry moth traps is essential to stop these house moths before they cause widespread damage.
Why do I suddenly have moths in my house?
Moth infestations most often come from Clothes Moths, Pantry Moths, or migrating moths. With migrating moths like Millers, an infestation will usually occur suddenly in the warmer spring or summer months. Pantry Moths and Clothes Moths can mature into adulthood from larvae simultaneously, causing what appears to be a sudden swarm from the pantry, closet, etc.
While migrating Millers are annoying, they do not generally cause damage to your home. However, Clothes Moths and Pantry Moths can both be incredibly detrimental to stored items like dry food goods or clothing. Combat them with a combination of moth traps, thorough cleaning, and targeted moth prevention techniques.
