Life
Cycle
Adult moths live for 15-30 days where upon mated females can lay 40-50
eggs singly or in groups. Eggs hatch
in 4-10 days in summer months and up to 30 days in winter. Larvae feed
and become mature in 35 days or as
long as 30 months depending on food quality, temperature and humidity.
Pupation will occur in infested
materials. Adults will emerge from the pupae in 8 to 40 days depending
on temperature.

Granular
frass the size of ground pepper can be found in, on and under:
- Fabric
- Furs
- Ttaxidermy
Mounts
- Hanging
clothes in closets
- Rugs
- Carpets
- Upholstered
furniture
|
Larvae damage:
- woolens
- Silks
- Furs
- Materials
made with hair and feathers
Larvae can
feed from short white webbing tunnels, but these are not always
present.
Pupal cases
can be found on surface or within pile of carpet and rugs or underneath
these materials.
The use of pheromone traps and inspections can determine location
and degree of infestation.

WHAT YOU NEED
TO KNOW ABOUT THE LURE:
BULLET LURE® . Contains sex pheromone to attract male moths.
Effective duration of attraction is 6-8 weeks.
Lure Storage
Keep unopened lures in cool storage (less than 60° F) or place in
freezer for extended storage. Lures can
remain frozen for up to 18 months to retain their full effectiveness
for use afterwards. Shelf life of lures at room
temperatures is 12 months.
Trap Designs
used with Lure:
No
Survivor hanging 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.
Trap Placement
Techniques
Timing -traps can be placed year round but should be in greater
numbers during the summer.
Density
- One to two traps per room that contains materials susceptible
to attack (see list above).
Location
- Place hanging traps at 4 feet above ground or lower. Place
in clothes closets (hanger bar) or warm, dark, quiet areas
such as behind couches, or areas where susceptible materials are present,
stored or displayed.
Trap and Lure
Maintenance
Traps must be replaced when filled with moths or become dusty. Traps
may remain sticky for many months.
Lures must be replaced every 6-8 weeks. The old lure can be left in
the trap.
Trapped beetles
should be recorded regularly on a separate monitoring data sheet to
determine trapping trends.
Expectations
1 moth per trap per week -- Inspection of materials susceptible to attack
should be carried out.
3-5 moths/ trap per week -- Serious damage is likely on a single item
or location in the area of the trap.
10+ moths/trap per week – Serious wide spread damage has occurred
in the room or storage area.
|
Important
Notes:
Large numbers of moths require other means of control and management
to eradicate infestations.
Traps may
catch sufficient number of males to prevent females from becoming
fertile. Female moths however,may actively fly around and not
be attracted to the traps.
