  • Wings: Moths typically have two pairs of wings covered in scales.
  • Eyes: They have a coiled proboscis and large compound eyes.
  • Size: Moths vary dramatically in appearance and size depending on the species. Some are massive and others tiny.
  • Color: Certain species of moths are brilliant with metallic colors while other are drab in browns or grey.

Most indoor infesting moths are smaller than 2 cm wingspan and often are shades of grey or brown to reddish brown.

How Did I Get Moths?

There are many different species of moths, but homeowners usually encounter clothes moths and pantry moths. These pests are attracted to a variety of household items, which they may use as a food source or a place to lay eggs.

Pantry moths, such as the Indian meal moth, eat dry goods, including grains, nuts, flours, spices, and chocolate. Clothes moths infest items like clothing and upholstery made of animal-based materials.

How Serious Are Moths?

The extent of moth damage depends on the degree of infestation. A large population in the house can be quite costly. Clothes moth larvae leave behind holes in garments and feces stains as they feed, while large amounts of food may need to be thrown away due to contamination from pantry moth webbing, cocoons, and droppings.

Signs of a Moth Infestation

Moth signs depend greatly on the species. Indoors, moths are detected by the adults as they fly about the room or rest on surfaces. Fabric-feeding moths are detected when feeding damage to fabrics is discovered. Some will also leave webbing, cocoons and even droppings as evidence of their activity. Stored product moths may leave behind damaged food items, webbing and droppings as well. Some moths will leave their food source when it time to pupate. The pupae may be seen in corners of cabinets, drawers or walls.

Behavior, Diet & Habits

Moth behavior, diet and habits are as varied as their appearance. They range from beautiful pollinators to sneaking blood feeders. Some moths are major agricultural pests, while the majority complete their life cycle with no significant direct impact on man. They often are the food source for many animals, including birds, mammals, reptiles, amphibians, insects, arachnids and even some plants. Indoors, homeowners most likely encounter moths that are either feeding on stored pantry items or on fabrics.

Damage caused by moths
Although they are most famous for their ability to ruin wool clothing, webbing clothes moths are also attracted to a variety of other natural materials, including silk, hair, felt, fur and feathers. These moths tend to measure 2.5 to 5 cm in length and are buff colored.

Webbing clothes moth larvae, not the adults, are responsible for destroying clothing. They prefer animal-based fabrics. Moths may consume sweaters, coats, blankets, carpets, decorative items, comforters, pillows and toys. They prefer not to feed on synthetic fibers, but will consume blended and stained fabrics.

Where do they hide?
They avoid light and are most commonly found in dark locations such as basements, attics and closets. Within these locations, moths can be found in the folds of fabrics or hiding in corners.

Infestations
Moths are capable of infesting a home long before their populations are noticed. As a result, substantial damage can occur to clothing or furnishings.

While some are harmless and others are known to be beneficial for their silk and nutritional value, most moths and caterpillars are considered nuisance pests. A few, including the Io moth, the saddleback caterpillar moth and the southern flannel moth, are more concerning because the larvae can sting. Particularly in agricultural communities, some moth and caterpillar populations cause severe damage.

Gypsy moth caterpillars are known to damage forested areas in the northern United States.

Fruit farms suffer from codling moth infestations, while cabbages and mustard crops are often destroyed by the diamondback moth.

Some moth larvae are known to consume cotton, tomatoes and corn. These larvae are commonly referred to as cotton bollworms, tomato fruitworms and corn earworms. Some moth species are also known to eat fabrics made from natural fibers, such as wool and silk.
