Common Carpet Beetle Treatment Products

Carpet beetles are a type of small pest beetle, the larvae of which feed on fabrics, carpets and fur. They prefer dark places and can quickly infest closets, warehouses and other spaces where clothing and fabrics are stored. Controlling these beetles requires eliminating the source of their food with routine cleaning and careful storage. In serious infestations, carpet beetle control may also involve a number of chemical products.

These resin strips contain a chemical called dichlorvos, a volatile organophosphate commonly used to control household pests. According to the University of California-Davis, these are more effective at protecting objects in closed containers and last longer than moth control products. Note that pest strips only work in airtight containers where their vapors can build up. In containers which are not airtight, they repel adults, but do not kill larvae.

Pyrethroid chemicals can be used to eliminate carpet beetles. They work by paralyzing the insect permanently. These chemical insecticides should not be used in areas where food is prepared or stored, as they may be dangerous. Pyrethroid insecticides are relatively non-toxic to humans, but some sensitive people may have problems with them. According to Ohio State University, some insecticides, such as delamethrin and permethrin, are more toxic. These should only be applied by a licensed pest control operator.

According to Golden Harvest Organics, diatomaceous earth is a naturally occurring substance formed from the remains of microscopic plants called diatoms. While the commercially available powder feels soft and silky to humans, the individual particles have very sharp edges, which cut through insect exoskeletons, allowing the insects to dry out and die. When ingested, diatomaceous earth causes internal damage. It is non-poisonous to humans and pets and can safely be used all over the house. However, it is an inhalation danger and requires use of a dust mask or respirator during application.
