1. What Are Larder Beetles?

Larder beetles, scientifically known as Dermestes lardarius, are common household and commercial pests recognized for infesting stored food products and other protein-rich materials. These beetles get their name from their propensity to invade larders, which historically were rooms or areas where food, especially meat, was stored.

1.1 Appearance

Adult larder beetles are typically about 1/4 to 1/3 inch in length and have a distinct appearance. They are dark brown to black with a characteristic pale yellow or cream-colored band across the upper portion of their wing covers (elytra). This band usually contains six dark spots, three on each side, making the beetle relatively easy to identify.

Larder beetle larvae are elongated and worm-like, growing up to 1/2 inch long. They are reddish-brown and covered with stiff bristles. The larvae also have two distinctive spines on their posterior end, which curve backward.

1.2 Habitat and Behavior

Larder beetles are commonly found both indoors and outdoors. Inside, they infest pantries, kitchens, and storage areas where food products are kept. They are particularly attracted to:

Stored Foods: Dried meats, cheeses, pet food, grains, and other stored goods.
Animal Products: Hides, furs, feathers, and dead insects or animals.

Outside, larder beetles can be found in:

Nests: Bird and rodent nests.
Carcasses: Dead animals.
Other Organic Matter: Areas with decaying organic material.

Adult beetles are most active in the spring and early summer, seeking out mates and new food sources. The larvae are voracious feeders and can cause significant damage to infested materials.

1.3 Life Cycle

The life cycle of a larder beetle consists of four stages: egg, larva, pupa, and adult.

Egg: Females lay eggs near a food source. The eggs are small, white, and typically hatch within a few days to a week, depending on environmental conditions.
Larva: The larvae are highly mobile and feed actively on available food sources. They undergo several molts as they grow, shedding their skin multiple times. The larval stage can last from a few weeks to several months, depending on food availability and environmental factors.
Pupa: When the larva is fully grown, it seeks a sheltered location to pupate. The pupal stage can occur in a variety of materials, including the infested food product or nearby cracks and crevices. This stage lasts about one to two weeks.
Adult: Once the pupal stage is complete, the adult beetle emerges. Adults are capable of flying and will search for mates and new food sources to continue the cycle.
