Larder beetles are known to be common household pests that can infest various food sources and other organic materials. These beetles, scientifically named Dermestes lardarius, often thrive in areas rich with high-protein content, such as dried meats, pet food, and even bird nests source.
A common question people have about these insects is whether or not they can fly. While the ability to fly might not seem like a significant detail, it could affect the beetles’ capacity to infest different areas within homes and other structures. Knowing if larder beetles can fly will allow for proper preventative measures to be taken, ensuring a more effective approach towards eradication.
Larder Beetle Overview
Appearance and Characteristics
The larder beetle, scientifically known as Dermestes lardarius, is a common household pest. Adult larder beetles are about 3/8-inch long and black in color. They have a distinctive broad tan band with black spots running across their front portion, called elytra, which covers their wings. The antennae can be seen projecting from the head region. A key characteristic of the larder beetle is its oval-shaped body.
Some features of larder beetles include:
- Oval-shaped body
- Distinct color pattern
- 3/8-inch size for adults
Life Cycle of Larder Beetles
Larder beetles undergo a complete life cycle consisting of four stages:
- Eggs
- Larvae
- Pupae
- Adults
Adult larder beetles typically overwinter outdoors and indoors. They lay their eggs in various food sources, which provide nourishment for hatched larvae. Once larvae are fully grown, they search for shelter to transform into pupae. The entire process from egg to adult takes about 40-50 days.
Habitat and Food Sources
Larder beetles prefer habitats rich in organic materials. They are commonly found in animal products, such as hides, dried meats, cheese, and feathers. They can also infest dry dog and cat food, bird feed, and even the remains of animals.
Some common food sources for larder beetles are:
- Dried meats
- Cheese
- Pet food
- Animal hides and remains
Homes may experience infestations when these food sources are readily available. It’s essential to identify and dispose of the beetle’s food source to control their population effectively.
Larder Beetle Infestations
Signs and Causes of Infestations
Larder beetles (Dermestes lardarius) can infest a variety of materials in a household. Signs of an infestation include:
- Adult beetles flying near lights or windows
- Dead beetles found near the infestation source
- Larvae feeding on materials like animal products, fabrics, or even dead insects1
Common causes for infestations may include improperly stored food, particularly animal-based products, and a lack of proper sanitation.
Common Locations for Infestations
Larder beetles can be found in various locations of a household:
- Pantry: Beetles infest food items, such as cured meats (ham, bacon), cheese, or animal feed
- Storage areas: The beetles affect materials containing fur, hair, feathers, hides, dead insects, and natural fibers
- Wall voids: Adult beetles may overwinter in wall voids, while larvae search for a shelter to transform into pupae2
Preventing and Treating Larder Beetle Infestations
To prevent and treat larder beetle infestations, follow these steps:
- Inspection: Regularly inspect pantry items and storage areas for any signs of beetles or larvae
- Sanitation and cleaning: Keep pantry areas and storage spaces clean and dust-free. Dispose of heavily infested food and material items3

Larder Beetles and Other Pests
Similarities and Differences in Appearance and Behavior
Larder beetles and other pests such as rodents, flies, and ants can be a nuisance in homes and gardens. Here are a few key features of these pests:
- Larder beetles:
- Adult larder beetles can fly
- Larvae can bore into wood and other soft materials1
- Rodents:
- Can’t fly but are skilled climbers
- Gnaw on materials like wood and plastic
- Flies:
- Fast-flying insects
- Can transmit diseases in their food-seeking behavior
- Ants:
- Highly organized colonies
- Can carry comparatively large loads
Some pests infest stored food products, like larder beetles, grain beetles, and carpet beetles. Additionally, certain pests, such as mites and boxelder bugs, are most likely found in skin and other organic materials.
Managing Multiple Pest Infestations
Managing different pests at once may require different control methods. Here are some steps to handle multiple infestations:
- Identify the pests: Knowing the specific pests will help determine the right control methods.
- Inspect the infested areas: Check stored food, skin, and nesting materials to gauge the infestation size.
- Control measures:
- Rodents: Use traps or baits to control the population.
- Insects: Apply appropriate insecticides or introduce beneficial insects like lady beetles for natural control5.
- Mites: Maintain proper hygiene and use targeted miticides.
- Monitor: After implementing control measures, monitor the area for the success of the methods and any remaining pests.
| Pests | Control Method | Pros | Cons |
|---|---|---|---|
| Rodents | Traps & Baits | Effective if placed correctly | May require time to reduce population |
| Insects | Insecticides | Can control specific pests | May harm beneficial insects |
| Mites | Miticides & Hygiene | Reduces infestations | Requires regular cleaning and upkeep |
Natural and Chemical Control Methods
Using Natural Remedies
One way to control larder beetles is by using natural remedies, such as:
- Diatomaceous earth: A fine powder made of crushed fossils which can be applied in infested areas to eliminate beetles and larvae.
- Vinegar and bleach: Diluted solutions of vinegar or bleach can be used for cleaning infested storage areas, as they act as disinfectants.
- Maintaining low humidity and light: By keeping storage areas dry and well-lit, you can create an unfavorable environment for the beetles, hindering their growth and reproduction.
