What You Should Know About Carpet Scarab

I think some of our readers have seen in their houses these tiny insects or their hairy larvae on the walls but many of them did not know what kind of insect it is. Today we will talk about the carpet beetle.
“Carpet beetles” so generically is called the set of species of the Coleoptera Order, the family Dermestidae.

Within this genus Anthrenus of the family Dermestidae exists a great variety of subgenera and species with similar characteristics. Most species of this genus are harmless insects but some of them are considered as a pest. Anthrenus verbasci and Anthrenus museorum are the most famous and habitual species.

Their larvae affect textiles such as wool, silk, fur, or other goods. The museum beetle, Anthrenus museorum is a pest that can cause damage to museum items or stored biological samples.

Anthrenus verbasci carob beetle is a very interesting and nice insect but at the same time it is unfriendly for its larva that causes damages in some articles. The adult insect has a rounded body, an oval shape resembling a ladybug; Is very small (up to 3 mm in length).


This species is cosmopolitan, color variable by the scales that cover the body. These strips of scales may be brown, beige, red, black, white, yellow. Often these scales will fall and the insect will turn black as it happens with the adults of Attagenus spp. In museum beetles the bottom of the body is blackish brown, lighter at the end of the abdomen, adorned with whitish spots.

The larval form of this beetle has taken a very different form from the adult insect. The larva is larger than the adult insect (about 5mm), the legs very small, the body segmented and covered with uniform and rigid hairs giving it a brush appearance. When the larva senses danger, it bristles the hair and makes the shape of the body more rounded.
These insects are not a problem for public health (neither bite nor transmit diseases) but we have to control their presence to avoid material damages.

Adults live outdoors, in nature or outdoors, feeding on the nectar of flowers or other vegetables. People infest the house, bringing flowers or plants home. They can also access the homes through the windows from landscaped areas or nearby farms.

Often people do not know that they have carpet beetle infestation because, because of their very small size, they are barely detectable. They are detected only in case of massive infestation. At home they are on the walls near windows, baseboards, window frames or doors.

The life cycle is long. At the end of spring the female lays eggs (20 to 100) in protected and dark places. This site may be a dead cockroach or a stuffed animal. On the outside they can lay their eggs in the nests of squirrels, birds, insect galleries or dead animals.


Eggs hatch in 2-3 weeks. Larval development is slow and can last up to 11 months. The larva changes 6 to 8 times before pupating.
In addition to dead cockroaches, the larva can eat carpets, curtains, coats, museum collections causing damage to all these items.

There are studies that say that occupation of housing infested by carpet beetles can cause dermatitis (inflammation of the skin) in sensitive people. Inhaling larval excrement and hair can cause inflammation in the lungs.

To solve the problem of carpet beetle infestation we can advise museums or private homes to store vulnerable and valuable objects in polythene bags to prevent the beetle from attacking them. The objects attacked can be released from the animal by putting them at least forty-eight hours in the freezer. Regularly vacuum the contaminated rooms to eliminate larvae, insect corpses and other dead organic materials. But in case of massive infestation, the best option is to call Daddys Pest Solution.
