Black Carpet Beetles in San Angelo

The black carpet beetle is the predominant and most harmful carpet beetle species in San Angelo. It poses a significant threat to various household items containing keratin, a primary protein found in animal hair and feathers. These beetles can cause damage to plant-based materials like cereals and grains, and even synthetic fabrics not derived from animal sources might be attacked. Furthermore, dried insect specimens, such as those found in insect collections, are also susceptible to destruction by these beetles. Given their potential to wreak havoc on diverse materials, it is important to be vigilant and take appropriate measures to protect valuable possessions from black carpet beetle infestations.

Black Carpet Beetle Habitat

In natural settings, female black carpet beetles actively seek out spider webs, bees, wasps, or bird nests to deposit their eggs. These nesting sites contain an array of dead insects, beeswax, pollen, feathers, or other debris that serves as nourishment for the beetle larvae. As spring arrives, adult black carpet beetles are lured by the allure of flowers and may accidentally find their way into homes and buildings. The curious larvae, driven by their quest for sustenance, may venture beyond their nests and venture into the attic and various corners of the house. Quite often, black carpet beetles hitch a ride into homes, unknowingly brought along with old woolens and carpeting.

Black Beetle Behaviors, Threats, or Dangers

Black carpet beetles are opportunistic scavengers. Within homes, they can become pests in kitchen cupboards and areas where woolen carpets or clothing are stored. Infestations may originate from nearby bird nests, animal carcasses, or accumulations of deceased insects like flies or lady beetles in attics or basements. Additionally, stored products like cereal, pet food, and birdseed are potential sources of black carpet beetles within households. Being aware of these various potential food sources can help in identifying and addressing potential infestations promptly. If you are dealing with a black carpet beetle infestation, always contact your local beetle exterminators.
