Full conversion of
Full cycle 240-1095
Egg (embryo) 5-24
Egg. Beetle develops slowly. The female lays up to 50 eggs directly on the food or somewhere nearby. In a heated room egg stage lasts 6-10 days.
Larva. The duration of the larval phase varies from 6 months to 3 years. Accordingly, this may increase the number of molting from 6 to 20 - in favorable conditions molts to 11 and in unfavorable - to 20-fold.
Doll. The pupal stage lasts 6-24 days.
Imago. The beetles do not feed, live off the fat reserves of the body. Adults fly. Life from 30 to 60 days.
Abiotic factors. Depending on the carpet beetle completes its development cycle for a few months in the heated rooms.
At low temperature and poor nutrition one generation beetle develops within 2-3 years. That is a year developing one generation in unheated areas of development time increases up to a year and sometimes more than a year.
They overwinter in foods in houses, elevators, warehouses, mills, factories, confectionery, bakery, in the warehouse and production areas with grain stocks. The larva completes development in the spring, pupate in May, the beetles emerge in June.

Cooling grain processing products, etc.
Cleaning grain processing products, etc.
Chemical methods of struggle
For chemical disinfection of various food products and insecticides used the following methods:
Formulations based on phosphorous hydrogen (phosphine)
Fumigation under plastic film
Fumigation in the fumigation chamber
Fighter control measures in the storage and production premises:
One of the important conditions to prevent contamination of products, facilities and equipment pest control in enterprises is a good condition and keeping it clean warehouse and manufacturing facilities.
