Adult moths live for 15-30 days. Mated females can lay 40-50 eggs singly or in groups. Eggs hatch in 4-10 days in warmer months and up to 30 days in cooler months.

Larvae feed and become mature in 35 days or and up to 30 months depending on food quality, temperature and humidity.

Pupation will occur in proximity to and within infested materials. Adults will emerge from the pupae in 8 to 40 days depending on temperature.

Damage & Detection for Casemaking Clothes Moth

Casemaking clothes moth larvae damage woolens, silks, furs and materials made with hair and feathers. The primary means of detection of casemaking clothes moth is the presence of silken cases that contain larvae.

During pupation, the silken cases can be found hanging from vertical surfaces and under horizontal surfaces such as shelves or bottoms of furniture.

These pupal cases can also be found within piles of carpet and rugs or underneath these materials.

Granular frass, the size of ground pepper, can be found in, on, and under fabric, furs, taxidermy mounts, hanging clothes in closets, rugs, carpets, and upholstered furniture. The use of pheromone traps and inspections can determine location and degree of infestation.

Monitoring Tips & Tricks for Casemaking Clothes Moth

Casemaking Clothes Moth Monitoring Guidelines 

Lure

The species-specific Casemaking Clothes Moth BULLET LURE® is the recommended lure to use when monitoring for this insect. It contains sex pheromone to attract male moths. 

The multi-species Clothes Moth BULLET LURE® can be used when multiple species of clothes moths are present, or a customer is unsure which clothes moth is causing damage. Both types of pheromone lures have an effective duration of attraction of 90 days.

Lure Storage 

Keep unopened lures in cool storage (less than 60° F) or place in the freezer for extended storage. Lures can remain frozen for up to 24 months or at room temperature for 12 months to retain their full effectiveness for use afterwards.

Trap Designs Used with Lure

NOSURVIVOR TRAPS are diamond shaped sticky traps that can be hung from many locations. This design is the preferred trap for this moth that flies well. 

FLAT TRAPS are a low-profile sticky trap which are another option that should be placed on a flat surface when a hanging trap is not preferred by customers.

Trap Placement & Use

Trap Placement Techniques

Pheromone traps can be placed year-round but are especially recommended when temperatures exceed 12.5°C (55°F). Hanging traps are more effective at capturing Casemaking clothes moths compared to flat traps.

Place hanging casemaking clothes moth pheromone traps 1.5 m (5 feet) above ground or at eye level to allow for easy inspection when monitoring traps. In areas such as a closet or home, place one or two pheromone traps per room.

In commercial areas such as warehouses or museums, place pheromone traps 7.5–15 m (25–50 feet) apart to determine the presence or absence of Casemaking clothes moths. Increase pheromone trap density to 4.5–7.5 m (15–25 feet) apart to help locate source of Casemaking clothes moths.

Keep pheromone traps 7.5 m (25 feet) away from exterior doors. Casemaking clothes moth pheromone traps are best utilized in areas that store items that contain natural fibers such as wool, hair, feathers, furs, and upholstered furniture (containing natural wools and leathers).

Trap and Lure Maintenance

Replace traps when glue is filled with insects or becomes dusty. Replace pheromone lures every 90 days. Replace all pheromone lures in a location at the same time. Do not cut the cap off the bullet lure. Do not stagger lure replacement over several weeks. Record date and number of catches to identify trending information.
