Appearance and Size of the Dermestid Beetles
Out of the 700 species of these beetles, 123 of them are found in North America alone. They can be found in several places, and their names are derived from the fields.

It is dark brown and has broad, yellow bands covered in three black spots on its wings. Another commonly found Dermestid Beetle is the black larder beetle. It has similar features, but it is black (as the name suggests) and doesn’t have any sign of yellow on its wings. Like we mentioned, every Dermestid Beetle differs from the other in appearance and size. The khapra beetle is commonly found in stores and shows an immense fascination for grains, straw, seeds, cereal, flour, hay, and dried vegetable products. Though it was first discovered in India, today it enters the US territories through the shipments of grains. These are the most commonly found Dermestid Beetles.
Distribution, Habitat, and Eating Habits
They are most commonly referred to as the skin beetles, though there are several other names that they called. The habitats of the Dermestid Beetles differ from one another. Most of the beetles in the Coleoptera family feed on dried plant parts and dead animal meat. They love to consume animal hair, pollen, dead insects, feathers, and natural fibers.

Dermestids reproduce nearby food sources. Before dermestid beetles lay eggs, they look for a place that has an adequate supply of food. Once it is taken care of, the female beetles lay their eggs in warm and desirable places that have access to a lot of food. These beetles lay as many as 150 eggs at a time, and the incubation process doubles when there is enough warmth. The incubation process lasts for a period of 10 – 12 days. The second the larvae hatch, they start looking for a food source, and that is when they begin infesting the place that is close to their nest. Young or larvae of the Dermestid Beetles can eat anything starting from linen, fabrics, wool, and silk. If there is any food with cocoa, the larvae will love to feast on it.
The Dermestid Beetles start eating double their body mass as soon as they grow.
The Life Cycle
The Dermestid Beetles complete the entire process of metamorphosis. It starts with laying the eggs, which hatches into a larva, transforms into a pupa, and finally becomes an adult Dermestid beetle. The time taken by the egg to grow into a Dermestid Beetle varies from one species to another. Several species take as long as two years whereas some develop in a matter of six weeks.

Kill them with the use of Insecticides
Once you are done cleaning, spray the areas that were infested by Dermestid Beetles with insecticides. You should see the list of bugs and pests the insecticide is capable of killing. The list should include carpet bugs. Don’t go around spraying your entire house. Be area-specific — areas like under the carpet, edges of rugs, closet walls, and fabrics on shelves. Never spray insecticide on clothes, bedding, and towels.
The use of Boric Acid
Carpet beetles can even lay eggs and start to multiply inside the cracks in walls, attics, and other unreachable places. When you are facing such troubles, all you must do is use boric acid. Make a solution of boric acid powder (one tablespoon) and hot water (two cups). Mix it well and then pour it inside a spray can. Spray it inside the cracks.
Sometimes all these solutions will be a waste if you don’t prevent their entry in your homes. To be sure that you don’t have to deal with carpet beetles again check your doors and screens for any cracks. Avoid bringing in plants that are attacked by Dermestid Beetles. Spray insecticide on your doors and entry points, and this will stop them from entering.
