What do moth larvae look like?

Moth larvae, better known as caterpillars, come in many different shapes and sizes depending on the species, but they usually have some common features. Most of them are long and cylindrical, with segmented bodies covered in fine hairs or bristles. Their colors can differ from creamy white to various shades of brown, green, or even bright patterns that help them blend in or send warning signals to predators. The head is typically darker and more distinct, equipped with small mouthparts for munching on all sorts of materials like fabrics, grains, and leaves.

Some moth larvae, like those of the clothes moth, are pretty small—about 1/2 inch long when fully grown. These little guys are often pale and a bit translucent, making them blend right into the fabrics they invade. Pantry moth larvae, such as the Indian meal moth, are similar in size but usually have a yellowish or pinkish tint and can often be found in stored food.

Many of these larvae spin silken webs or create tunnels as they move around and feed, leaving behind webbing and frass (that's just a fancy term for insect droppings) that can help you spot them. Knowing what moth larvae look like and how they behave is key for catching infestations early, whether they're in your clothes or food. Regular checks and cleaning, plus smart storage practices, can really help reduce the damage these pesky critters can cause.

Do moth larvae damage clothing and fabrics?

Yes, moth larvae are well-known for ruining clothing and fabrics, especially those made from natural fibers. The larvae of clothes moths, like the webbing clothes moth (Tineola bisselliella) and the casemaking clothes moth (Tinea pellionella), can be particularly destructive. They munch on the proteins found in materials like wool, silk, cashmere, and fur. These little guys are attracted to dirty fabrics that have bits of sweat, food, or other organic stuff, which gives them extra nutrients.

As they nibble through the fibers, moth larvae create small, irregular holes in your clothes and textiles. This feeding can lead to serious damage to garments, carpets, upholstery, and other household items. Often, infestations go unnoticed until the damage is pretty extensive since the larvae like to hide in dark, undisturbed spots like closets, drawers, and storage boxes. If you see visible holes, silken webbing, or frass (that's insect droppings) on your fabric, you might have a problem.

To prevent moth larvae from causing damage, it's a good idea to regularly clean and vacuum your closets and storage areas, wash or dry-clean clothes before stashing them away, and use airtight containers for long-term storage. If you're dealing with a serious infestation, getting professional pest control from us here at Youngs Pest Control may be necessary to get rid of the larvae and protect your valuable fabrics.
