This moth is a serious pest of many stored food items. Dry pet food,
dry fruit and grains, bird seed, nuts, walnuts, and spilled pet foods are likely
sources of an infestation. Adult moths are about 5/8"
across the wings. They can be told apart from other indoor moths by their
distinctive forewings: the outer two-thirds of the wing is reddish brown and the
inner third grayish white. You may also find moths in the kitchen or other rooms.
Adults do not feed, but they lay eggs on food materials. The larval stage
causes the injury. Larvae are generally surface feeders but can feed within the
grain. As they feed, larvae spin silken thread webbing throughout the infested
food source. Small particles are often adhered loosely to the threads.
When full-grown, larva migrate out of the food source and often across walls
and ceilings, making cocoons in cracks and crevices, emerging a few days later
as adult moths. They are frequently found
making cocoons in cracks and crevices on cupboard tops, shelves, ceiling
corners, and walls. The complete life cycle from egg to adult moth takes
one to two months.
Try and locate the source of
infestation before any type of treatment. Examine closets, pantry's and stored goods for larvae,
moths, and damage. Sanitation, Sanitation, Sanitation! Get the idea?!
Infested items should be thrown out,
or placed in a seal tight container and frozen for a couple of days.
Freezing the infested items will kill all lifecycle stages of this pest.
Vacuum and clean all cracks and crevices in
closets and other rooms infested.
Destroy cocoons and larvae that may be found in the cracks between shelves, moldings, and
doorframes, on ceilings of cupboards, or where room walls and ceiling meet.
After vacuuming cracks and crevices in closets and other rooms
infested, an Indian
Meal Moth Pheromone Trap can be placed in areas that contain items the larvae feed on. In small areas, we recommend just one trap.
Too many traps will confuse the moths and you won't achieve proper control.
For larger areas such as warehouses and retail stores, place the traps every 25
- 50 feet apart on a grid pattern. The recommended height is eye level.
Pheromone traps provide you with a good way to monitor your population.
Gentrol is not an insecticide, but an Insect Growth Regulator (IGR) that provides preventative action, since it disrupts the pests' normal development.
Hydroprene, the active ingredient, prevents the pest from developing and thus
reproducing. Apply Gentrol to areas of infestation. Especially areas
where you see larvae. Areas to consider would be under the bottom side of
shelves in the pantry, cracks and crevices, behind baseboards, behind loose
wallpaper, in floor cracks, cracks in plaster, behind cabinets, under cabinets,
behind the dishwasher, or in existing wall holes.
Place the
Pantry Patrol Pheromone Trap
in infested areas.
This pheromone based trapping system utilizes powerful sex attractant and
aggregation pheromones mixed in a natural grain oil. This food attractant is
designed to lure and capture a variety of beetles and moths that attack your
stored food. Sold in packages of two.
Should you need to take a more aggressive approach to controlling your
infestation, try utilizing some common insecticides.
Use
a dust such as Drione or
Delta Dust to treat cracks, crevices, or inaccessible void areas such as
under cabinets or dish washers. Use the White Crusader to
make your application.
For added control, you may wish to resort to a residual insecticide such as
Tempo SC or Suspend.
Good housekeeping is
critical for preventing or controlling Indian Meal Moths. Never allow
stored products to lie in a neglected pile. Regular use of a strong suction
vacuum cleaner with a crevice tool to remove food products from floor
cracks and baseboards is necessary.
Keep the pantry and kitchen clean!
