Moths can be an unexpected and frustrating presence in your home. Whether they’re fluttering around your pantry or chewing through your favorite sweater, these tiny pests can feel like a mystery. If you’ve ever found yourself asking, “Moths in my house, where are they coming from?”
Understanding Moths: Types Commonly Found in Homes
Moths come in many species, but only a few are commonly found indoors. Knowing the type of moth you’re dealing with is the first step in addressing the problem.
Clothes Moths
Clothes moths, as the name suggests, are notorious for damaging fabrics. They thrive in dark, undisturbed spaces, such as closets or storage boxes.
- Appearance: These moths are small, usually about ½ inch long, with golden or buff-colored wings.
- Behavior: Clothes moths are attracted to natural fibers, such as wool, silk, and cashmere. They feed on keratin, a protein found in animal-based materials.
- Damage: It’s not the adult moths but their larvae that cause damage. These larvae chew on fabrics, leaving behind holes and frayed fibers.
Pantry Moths (Indian Meal Moths)
Another common household moth is the pantry moth, which infests food storage areas.
- Appearance: Pantry moths are slightly larger than clothes moths, measuring about ½ to ¾ of an inch. They have brownish-gray wings with a coppery sheen.
- Behavior: These moths target dry, stored food such as grains, cereals, nuts, and pet food. They lay eggs in food packaging, and the larvae contaminate food with silken webbing.
- Damage: Infested food becomes unusable due to the contamination of larvae, webbing, and droppings.
Other Moth Species
While clothes and pantry moths are the most common, other species, such as carpet moths or birdseed moths, may occasionally find their way indoors. However, their presence is often tied to specific conditions, such as unclean carpets or improperly stored food.
Where Are Moths in My House Coming From?
When moths appear in your home, they don’t just show up by magic. They either find a way in from the outside or are inadvertently brought in by you. Let’s explore the common ways they enter your home.

Eggs and Larvae Hitchhiking Indoors
Moth infestations often start before you even realize it. Here’s how:
- Contaminated Clothing or Furniture: Clothes moth eggs or larvae may be hiding in secondhand clothing, rugs, or upholstered furniture you bring into your home.
- Infested Food Products: Pantry moths often enter your home through infested food packaging. Items like grains, cereals, and pet food are common culprits.
- Carpets and Rugs: Eggs and larvae can be present in rugs, especially if they are made of natural fibers.
Entry Points for Adult Moths
Adult moths can also find their way into your home through:
- Open Doors and Windows: Moths are attracted to light, so they may fly indoors at night if windows or doors are left open.
- Cracks and Gaps: Moths can enter through small gaps around windows, doors, or vents. Plumbing lines and cable openings can also provide entry points.
Attraction Factors Inside the Home
Certain conditions inside your home can make it more attractive to moths:
- For Clothes Moths: Organic debris, such as sweat, hair, or food particles, on fabrics can attract these moths. They prefer dark, undisturbed areas, such as closets or storage spaces.
- For Pantry Moths: Food stored in open or improperly sealed containers is a magnet for pantry moths. They are particularly drawn to grains, flour, and pet food.
Summary of Moth Origins
Moths can enter your home in multiple ways. Whether it’s through infested items, open windows, or improperly sealed food, these pests are opportunistic. Understanding their entry points and attraction factors is key to tackling the problem.
The Life Cycle of Moths and Its Role in Infestations
To effectively control moths, it’s essential to understand their life cycle. Each stage of their development plays a role in infestations.
The Four Stages of a Moth’s Life Cycle
- Egg: Moths lay eggs in hidden, dark places like closets or pantries. These eggs are often too small to notice.
- Larva: The larval stage causes the most damage. For clothes moths, larvae chew through fabrics, while pantry moth larvae contaminate food.
- Pupa: During this stage, larvae spin cocoons and transition into adult moths. They often hide in crevices or folds of fabric.
- Adult: Adult moths primarily focus on reproduction. While they don’t cause direct damage, they lay eggs that start the cycle again.
Why the Larval Stage is Most Problematic
Larvae are the most destructive stage of the moth life cycle. They feed voraciously, whether on fabrics or food, causing noticeable damage. Eggs and larvae are often hidden, making early detection difficult.
Common Signs You Have a Moth Infestation
How do you know if you have a moth problem? Here are some telltale signs:
- Visible Adult Moths: Seeing moths fluttering around your home, especially near closets or pantries, is a clear indication of a potential infestation.
- Webbing or Clumping in Food: Pantry moth infestations often leave behind webbing in grains or flour, as well as clumps of contaminated food.
- Holes in Clothing: Small holes in wool, silk, or cashmere fabrics are a clear sign of clothes moth larvae.
- Cocoons or Larvae: Finding cocoons in dark corners, closets, or pantries indicates an active infestation.
- Unpleasant Odors: A musty smell in closets or storage areas can sometimes be associated with moth infestations.

Close gaps around windows, doors, and vents to prevent adult moths from entering. Weatherstripping and caulking are effective solutions.
