Cigarette and Drugstore Beetles
The cigarette beetle and the drugstore beetle closely resemble one another, but the cigarette beetle is the more common of the two. Both beetles have a "hump-backed" appearance.
Both beetles are about 1/8 inch long, cylindrical, and uniformly light brown.
The wing covers of the drugstore beetle have longitudinal grooves, while those of the cigarette beetle are smooth.
Also the body hairs of the cigarette beetles are considerably longer, giving it a more "fuzzy" appearance.
The cigarette beetle feeds on cured tobacco, cigarettes, and cigars. It may be a serious pest of items such as books, flax, cottonseed meal,cereals, and cereal products, animal products,wool, rice, ginger, pepper,paprika, dried fish, seeds, and dried plants.
In the home this beetle is most commonly found in pet foods, cereals, nuts, and candy.
The cigarette beetle lays its eggs in the food substance.
The small, yellowish white grubs are covered with long, silky, yellowish brown hairs and are about l/6 inch long when fully grown.
The pupae are within a closed cell composed of small particles of the food substance cemented together with a secretion of the larvae.
The period from egg to adult is about 6 weeks.
The drugstore beetle is a very general feeder, attacking a great variety of stored foods, seeds, pet foods, spices, and flour mixes. One of the more commonly infested materials is nibbled dog food.
It gets its name from its habit of feeding on almost all drugs found in pharmacies.
In the home, however, the most common food materials to find this beetle infesting are pet foods, drugs, and cereals.
The drugstore beetle lays eggs in almost any dry, organic substance.
After hatching, the small, white grubs tunnel through these substances and, when full grown, pupate in small cocoons. The entire life cycle may take place in less than 2 months.
Recommended Control for Pantry Beetles
With a "beetle" or "weevil"type of panty pest you should use:
InVite Multi-Lure Oil - five pheromones for various pantry beetles and moths combined in gelled food oil base.
Contains: One tube and 6 unscented glue boards
Target Insects:
Beetles : Cigarette, Warehouse, Khapra, Flour, Saw-Toothed Grain, Drugstore and other beetles.
Moths: Indian Meal, Almond, Tobacco, Mediterranean Flour, Cacao, Raisin and other Ephestia Moths
MicroCare Aerosol
a residual pryethrin aerosol ,with a crack and crevice tip , sprayed in
the cracks and crevices, to kill the adult beetles .
You will need 2-4 treatments spaced about 3 weeks apart, due
to the nature of their cycles.
D-Fense SC Insecticide
Use one gallon of finished product per 1,000 sq. ft. to
allow for proper penetration.
Retreat at least two more times, at intervals of 3 weeks.
When spraying rugs or area rugs it would be advisable to spray
underneath the underside of the rugs a couple feet or the
entire underside.
Although larva and adults may be easily killed, eggs and pupa
are not, a complete vacuuming is important.
The first thing needed to done is the elimination of the
source of infestation.
You should make a thorough inspection of infested premises
to find all sources of infestation
- In private residences the pantry pest such as the Indian
meal moth is usually brought in products from the grocery
stores. It is usually just in one area, but can spill over
into other areas.
Prevention and Sanitation:
- Place exposed food in containers with tight-fitting lids
.
- Periodic cleaning of the shelves helps to prevent infestation
of stored food products by pantry pests.
Certain pantry pests need only small amounts of food to live and breed. - Some infestations of packaged food originate in the food-processing
plant or warehouse.
Broken packages should not be purchased, or should be exchanged for unbroken packages when discovered, for the chance of these being infested is greater than for perfectly sealed ones. - Do
not mix old and new lots of foodstuffs.
If the old material is infested, the pest will quickly invade the new. - If you are unsure about an item being infested, place it
in a plastic bag where you will be able to catch anything
that emerges.
If you find the pantry pest accumulating in the bag, you know the foodstuff is contaminated and needs to be discarded.
To insure any item is pest free, store it in these clear bags for at least a month. Sometimes it takes even longer for the adults to emerge. - Infestations are most likely to occur in packages that have
been opened for the removal of a portion of the contents
and then left unsealed for long periods.
Some of the pests may find their way into other food packages, but even those in a single package may become so numerous that large numbers may find their way into every suitable material in the home, and will eventually crawl over floors, climb up walls, and gather about windows. - Clean old containers before filling them with fresh food.
They may be contaminated and cause a new infestation.
- Make
sure that cabinets and storage units are tight and can be
cleaned easily.
- Store bulk materials, such as pet foods, in containers with
tight-fitting lids.
- Keep storage units dry. This is important because moisture
favors the development of pantry pests; dryness discourages
them.
- Some pantry insects breed in the nests of rodents and insects
and may migrate from these into homes. Eliminate any nests
found in or near the home.
-
Pantry pests can also breed in rodent baits. Be sure to
frequently check and discard infested baits.
Controlling Temperature:
When packages of food are found to be infested with moths or beetles, either low or high temperatures may be used to control the infestation. Insects are cold-blooded; their body temperatures closely follow that of their environment.
The most favorable temperature for most pantry pest is about 80°F. Above 95°F or below 60°F, reproduction and survival is greatly reduced.
When temperatures are lowered, insect activity decreases until all activity stops. The quicker the drop in temperature, the quicker the kill.
Although insects will be killed, their bodies will remain in the food unless sieved out.
An exposure of 2 to 3 days to temperatures of 5°F or lower kills the more susceptible stages (larvae and adults), but eggs require longer to kill (3 weeks).
An alternative is to freeze the food for a week, remove it from the freezer for a few days, and then refreeze it for another week.
