Khapra Beetles: Biology, Identification, Beetle Control
biology and habits of the Khapra Beetle will help correctly identify which
beetle has infested your home or business and how to control the pest. You
need to know the type of foods the beetle feeds on and its life cycle in order
to make a thorough inspection and to choose the best pest control methods.
Integrated pest management requires knowing as much as possible about the
targeted pest, changing its surroundings to limit its entry and its
Beetle Description: Small round
beetles; 1/8” long with dark colored pattern on back usually yellow and brown
with various shades on their wings.
Biologyof Khapra Beetles: Discovered in the US in 1946, Known to infest warehouses and food processing plants and can infest any structure and prospers in pantries, closets, garages, laundry rooms, and basements where wheat, grain, cereal, barley and rice are stored. Khapra beetles thrive on pet food, grass seed, bird seed and in areas with large Pecan, Walnut, Acorn and other nut trees
Cycle and Habits of Khapra Beetle: Larva begin to feed as soon as they find food and will continue for a month.
They will then pupate into adults and begin mating and laying eggs. The stages
from Larva to adult usually last two to three months, though it is not uncommon
to last three to four months. Khapra beetles multiply at an increased rate if
food supplies are in abundant. In the average home, infestation is usually
limited to a few rooms.
Khapra Beetle Control Measures: Discard any food item suspected of harboring larval or adults. Empty cabinets and treat with Baygon Aerosol in all cracks and crevices where adults like to lay eggs. This spray will break the cycle by killing off emerging larva which will be hatching from eggs that have been laid undetected or hidden from view.
If Khapra Beetles are found throughout the whole house treatment using Permethrin in a pump sprayer should be used, treating all baseboards throughout living areas and in unfinished basements and garage areas. This should last 2-4 weeks and provide a residual so that emerging larva will die off while seeking food.
