Adult cigarette beetles live 2 to 4 weeks. Once eggs hatch they become larvae and feed on nearby food sources. Infested products often have small round “shot holes” in packaging and large amounts of dusty frass (insect waste) inside. Non-chemical Control. the lower the temperature the slower the process) and food source. The larvae are about 0.1 inch long when fully grown. Larvae are found in foodstuffs. The speed of development through the life cycle depends on temperature, moisture, quality and abundance of food. The length of the cigarette beetle life cycle is highly dependent on temperature and the food source but usually takes 40 to 90 days. Life History The adult beetles live from 2 to 4 weeks, and during this time the females may deposit as many as 100 eggs. The life cycle of drugstore beetles takes about 75 days to complete, depending on the conditions of the surrounding environment. The complete life cycle takes about 75 days depending on conditions. The larval period ranges from four to five months and the complete life cycle requires seven months. Drugstore Beetles and Humans. Cigarette beetle larvae are hairier than those of the drugstore beetle. https://en.wikipedia.org/wiki/Home-stored_product_entomology Signs of Infestation of Drugstore Beetles .

Ideal temperatures for life cycle development are around 85 degrees Fahrenheit with 60 to 90 percent relative humidity. Favourable condition. Cigarette Beetles are good fliers. Female drugstore beetle lays eggs singly in almost any dry organic substance. Eggs are laid in crevices in the commodity. Life Cycle: Females lay the eggs one-by-one in the larval food source. Reproduction & Life Cycle. Larvae tunnel through the product, munching as they go. The female can lay 40 to 60 eggs over her life span. Cigarette beetle life cycle and breeding. Eggs of both beetles are pearly white, and are not easily seen with the naked eye. Drugstore beetles are more reproductively successful at warm temperatures. The head is deflexed, but does not result in a distinct humpbacked appearance. The female lays 30 to 100 eggs, deposited in food, and the eggs hatch one or two weeks later. The females lay their eggs on the food material and will hatch within a few days. In warm temperatures, the entire life cycle from egg to adult can be completed in 45 days. Thus the mating call can be heard in a quiet infested house. In cool temperatures (below 15ºC) there is only one generation per year, in moderate temperatures two, while … The female beetle lays about 60 eggs. Female Drugstore beetles lay eggs, normally about 75 at a time, on a food product. Life History. Adult females live approximately 13 to 65 days. Drugstore beetle (Stegobium paniceum) Adult Side View Drugstore beetle (Stegobium paniceum) Adult Front View Drugstore beetle (Stegobium paniceum) Larva. The drugstore beetle requires about two months to complete its life cycle. It gets its name from its habit of feeding on prescription drugs. Drugstore Beetle Life Cycle. These beetles can be found in any facility that handles food such as homes, mills, warehouses, granaries, bakeries, and stores. Larvae form a little round ball or cell which becomes its cocoon, and in which it pupates. Female drugstore beetles lay single eggs in areas where they feed. In homes, spices and dry pet food are very common foods for cigarette beetles. Commonly encountered species of stored product beetles in Canada include the confused flour beetle, the hairy spider beetle, the foreign grain beetle, the red flour beetle, the drugstore beetle, the cigarette beetle, and the sawtoothed grain beetle. Drugstore Beetle, Stegobium paniceum. Females lay 10 to 100 eggs in the food and the larvae emerge in six to 10 days. The drugstore beetle will attack such a wide variety of foods and material that one entomologist stated that they “eat anything except cast iron.”Adult female drugstore beetles lay eggs singly in foodstuffs such as, flour, meal, breakfast foods, bread, books, etc. It has a life cycle of about 60 days. The cocoon lasts 12 to 18 days. DRUGSTORE BEETLE (Stegobium paniceum)Food: This insect is also a common pest of dried plant matter. Most drugstore beetle life cycles take 6 months to complete but in warm climates like the south, three cycles can be completed in one year. The larvae are about 1/6 inch long when full-grown, whitish in color, with the head dark brown or tan. SIZE: The drugstore beetle ranges in size from one-tenth to one-eighth of an inch in length. The eggs will hatch in 6 to 10 days. The Drugstore beetle also feeds on flours, dry mixes, breads, cookies, chocolates, and spices. It has a three-segmented club on the antennae. In common with other beetles, this species passes through four life-stages: egg, larva, pupa and adult (pictured below). Be sure to read and follow all the instructions and safety precautions found on the pesticide label before using any pesticide. Life Cycle and Habits. The name of this wood boring insect comes from the ticking/banging sound that the male makes banging his head against the wood, in order to attract females. The larvae have six to nine instars and are about two-tenths inch long when fully developed. Small white grubs emerge from the eggs and then tunnel through these substances. Drugstore beetles’ larvae crawl within the foodstuff while feeding. Drugstore Beetles are generically and unscientifically categorized on our site with other small but unrelated insects that infest stored foods in the pantry. The wing covers have longitudinal lines. Life cycle: The life cycle of the drugstore beetle takes three to four months at room temperatures. The pantry bugs info from the University of Florida states that the adult drugstore female beetle can lay close to 75 eggs within the foodstuffs. Cigarette beetle larvae are yellowish-white and grub-shaped, with three sets of forelegs and a brown head capsule. Common pests include the red and confused flour beetles, sawtoothed grain beetles, drugstore beetle, cigarette beetle and Indian meal moth. The development from egg to beetle at 18 ºC is 7 months. They have also infested books, dried flowers, spices, leather, silk, old rodent bait and even museum specimens. The life cycle of the drugstore beetle. Life cycle: Female drugstore beetles lay eggs singly in foodstuffs. The larval stage ranges between four and twenty weeks depending on the quantity and type of food source. A female will lay 100 white, oval-shaped eggs at a time that will hatch approximately 10 days later. A much larger number of insects feed on processed grains or broken kernels, or a variety of spices.

Small C-shaped grubs can be found feeding inside infested products. The wing covers of the drugstore beetle have longitudinal grooves while those of the cigarette beetle are smooth. It is 2.5 mm long and brown. Development occurs between 60 to 93°F (~15 to 34°C) but is optimal at about 85°F (~30°C) and 60 to 90% relative humidity. The entire life cycle is generally less than two months but can be as long as 7 months. Just like many other pests, cigarette beetles are prolific breeders. The hairy, white larvae are fed bits of food in a cocoon and will emerge within three weeks. Also, the body hairs of the cigarette beetles are considerably longer, giving it a more "fuzzy" appearance. The duration of the life cycle is highly de-pendent on the temperature and food source. Adults can fly and are attracted to light. The elytra (wing covers) of the drugstore beetle have rows of pits giving them striated (lined) appearance. The life cycle takes about 6 weeks. The adult resembles a clothes moth but can be recognized by the finger-like projection of the hind wing tip. Prevention and Control. They lay up to 100 eggs in a span of 3 weeks.
