The amber carpeting beetle, additionally accepted as the vodka beetle, was alien to Britain in the 1970s and is acceptable added accepted as a annoyance of accustomed history collections and a accessory domiciliary pest.
Adults accept egg-shaped bodies 2-5 mm continued and 2-2.5 mm wide, with a atramentous abject colour and close hairs giving amber to reddish-yellow elytra (wing cases). The arch and top allotment of the bust (the beetle’s average section) are aphotic red-brown to black. The antennae and legs are brownish to yellow. Males accept a actual continued aftermost (11th) antennal segment, four times the breadth of the antecedent two segments together. The females are beyond than males, with beneath antennae. There is one ocellus (simple eye) arresting in the average of the head.
The larva of the amber carpeting beetle is up to 8mm continued back absolutely developed, torpedo-shaped, cone-shaped from arch to the end of abdomen, which continues with two brush-shaped tufts of hair. It apparently resembles a actual aphotic silverfish. The segments are actual visible, which accord the larva a affiliated appearance, with darker stripes added than the lighter ones. Its colour is bronze-brown upperside and yellowish-brown underside, with aureate chicken hairiness and a scaly boyhood of the aforementioned colour on bust and belly segments. The larva avoids light. Larvae of added Attagenus breed are actual similar.
The beetle originates from East Africa, from breadth it was accidentally alien to Russia breadth it was aboriginal empiric in 1961. From there, it advance to altered genitalia of Europe, including Britain. It was begin actuality aboriginal in a baby breadth about London, but it is now acceptable added accepted in England.
It is a annoyance of accustomed history collections and a domiciliary pest. In attributes it lives in birds’ nests and bats’ roosts, but it has became a synanthropic species, acceptation it prefers to alive in and about beastly dwellings. It has been recorded alive on carpets, boner on attic and on asleep dry insects. It has additionally been begin alive in stored articles in Africa and Europe. The larvae augment on a array of abstracts absolute keratin, such as wool, fur, hide, feather, etc. It is a warmth-loving species, so it depends on axial heating for adaptation in Northern Europe.
The adults can alive afterwards feeding, but the larvae depend on dry substances of beastly agent to develop.
The optimal altitude for the development of Vodka beetles are: 24°C temperature, 70-80% about air clamminess and abounding aliment supply. In these ideal conditions, the changeable lays 30-50 eggs in baby holes or added ambuscade places, the eggs bear in 10 days, the larvae complete their development in 3 months afterwards which they pupate and again appear as adults in 8-13 days.
In absolute situations, the development may be abundant slower, the activity aeon capricious from 6 to 18 months. The larva molts its bark 12 times during the accomplished cycle. In assuredly acrimonious bounds in Europe both adults and larvae can be begin year round, but adults are added accepted from March to September.

Preventing an bane is the best way to abstain damage. Amber carpeting beetles can be monitored with adhesive traps, pheromone lures and abecedarian aliment monitors. Quarantine is an important bactericide admeasurement back affective altar amid collections or houses. Advancement a austere hygiene by charwoman and removing abeyant aliment sources like fluff, feathers, etc. from aloof places such as amid floorboards will anticipate an infestation. In building collections and accumulator facilities, advancement low temperature and air clamminess will anticipate or apathetic bottomward abecedarian development.
If an bane has occurred, it can be controlled by concrete measures such as auctioning infested items, vacuuming and brushing. Back possible, abysmal freezing specimens or infested altar should be agitated out to annihilate larvae and eggs.
Chemical ascendancy involves appliance of insecticide, fumigating, gas treatment, etc.
