Larder Beetles: Identification, Habitat, Behavior, and Control

Larder beetles are common household pests that belong to the family Dermestidae. These beetles are named after their affinity for stored food products, particularly meat and other animal-based materials. Larder beetles can infest homes, grocery stores, museums, and other places where food or organic materials are stored. Understanding their identification, behavior, and control methods is crucial for effectively managing larder beetle infestations.

Larder Beetles


Larder beetles have distinct features that can help with their identification. They are approximately 1/4 to 3/8 inch long and have an elongated oval shape. The body is covered in dense hairs, giving it a fuzzy appearance. The coloration of larder beetles can vary, but they typically have a dark brown or black background with a pattern of light-colored bands or spots on the wing covers (elytra). The larvae of larder beetles, known as “woolly bears,” are elongated and covered in bristly hairs with a reddish-brown to black color.

Behavior and Habits

Larder beetles are scavengers and feed on a wide range of organic materials, including dried meats, pet food, dead insects, feathers, fur, and animal hides. They are attracted to protein-rich substances and can infest pantry items, stored food products, and animal carcasses. Larder beetles typically gain access to homes through cracks, gaps, or openings in doors, windows, or walls. Once inside, they can reproduce and establish infestations in hidden areas such as wall voids, attics, or crawl spaces.

Extermination Techniques

  1. Identification and Inspection: Proper identification of larder beetles and locating their breeding sources are essential for effective control. Inspect areas where infestation signs are observed, such as pantries, food storage areas, and areas with potential food debris or organic materials.
  2. Sanitation: Eliminate potential food sources and remove infested items. Thoroughly clean and vacuum-infested areas to remove larvae, eggs, or adult beetles.
  3. Exclusion: Seal any cracks, gaps, or openings that may serve as entry points for larder beetles. Repair damaged screens, seal gaps around doors and windows, and ensure proper storage of food items in airtight containers.
  4. Insecticide Application: In cases of severe infestations, targeted insecticide applications may be necessary. Consult with a professional pest control service, such as Arete Pest Control, to determine the appropriate insecticide and application method for your specific situation.
  5. Professional Assistance: If larder beetle infestations persist or are widespread, it is recommended to seek professional pest control services. Experienced technicians can assess the extent of the infestation, implement effective control measures, and provide long-term prevention strategies.


Proper sanitation, cleaning, and regular vacuuming can help reduce larder beetle populations. Maintaining cleanliness in storage areas and promptly disposing of infested items can limit their breeding sites. However, in severe infestations, professional pest control services may be necessary to achieve effective control.

In conclusion, larder beetles can be a nuisance in homes, causing contamination and spoilage of stored food products.
