LARDER BEETLE EXTERMINATOR - MONTREAL & SOUTH SHORE
About Larder Beetles (Dermestes Lardarius)
Activity
Larder beetles are active throughout the year, with a significant increase in activity during warmer months. These pests tend to be more active at night, coming out of hiding to search for food sources in secluded, dark places such as storage spaces, cupboards, and hidden corners. While their activity may decrease in colder weather, they can still survive in heated indoor environments where food is available. Their nocturnal nature and preference for dark spaces make it difficult to detect them, as they remain hidden during the day.
​
Diet
Larder beetles are primarily scavengers, feeding on a variety of organic materials, especially animal-based products such as dried meat, furs, and stored food items. These beetles thrive in environments where such materials are available, and they often infest areas with improperly stored food or animal products. They do not target living organisms but instead feed on decaying or exposed materials. A noticeable infestation usually indicates that there is an abundance of food sources available to sustain their population.
​
Size
Larder beetles are small insects, typically measuring between 6 and 9 millimeters in length. Their oval-shaped bodies are often brown with distinct markings, making them somewhat easy to identify once spotted. However, their small size and tendency to hide in dark corners or within food packaging can make them difficult to detect until the infestation becomes widespread. Their presence in areas like food storage units, attics, or storage spaces can go unnoticed for long periods, allowing the infestation to grow.
​
Habitat in Quebec
Larder beetles are commonly found throughout Quebec, particularly in areas where food or animal-based products are stored. They are often seen in homes, food storage facilities, and warehouses that contain improperly sealed or exposed food. Larder beetles are also found in areas like butcher shops, warehouses, and barns where animal products such as furs and meats may be stored. Without proper precautions, these beetles can easily infest both residential and commercial spaces, contaminating food supplies and damaging stored goods.
​
Inside Buildings
Inside homes and businesses, larder beetles are most often found in kitchens, food storage rooms, and pantries where they can access animal-based materials. They are especially attracted to improperly sealed or neglected food packages, as well as areas where meat, dried animal products, or furs are stored. Larder beetles can also infest areas like basements or warehouses that contain exposed animal products. They tend to hide in dark, quiet spots, making them difficult to detect until significant damage is done to food or materials.
​
Outside Structures
While larder beetles typically infest indoor environments, they can also be found in outdoor structures such as sheds, barns, and storage units where food or animal products are stored. They are attracted to exposed materials or food items left improperly sealed outdoors. Though they do not breed outside in the same way as some other pests, they can easily move indoors if not controlled, leading to an infestation in homes or businesses.
​
Breeding Preferences
Larder beetles breed in dark, warm, and undisturbed areas where food sources are abundant. They typically lay their eggs on animal-based materials like dried meat, furs, or other food products that have been exposed or improperly stored. The larvae hatch and feed on these materials, eventually maturing into adult beetles. Larder beetles do not require standing water to reproduce, which allows them to thrive in a variety of environments. Their ability to adapt to dry conditions makes them particularly prevalent in areas where food products are stored improperly.
​
Common Larder Beetle Species in Quebec
Larder Beetle (Dermestes maculatus): The most commonly encountered species in Quebec, this beetle infests areas where animal-based products, including dried meat, furs, and animal skins, are stored. It is known for damaging food supplies and materials, making it a significant pest in homes and businesses.
Variegated Carpet Beetle (Anthrenus verbasci): Although not a true larder beetle, this species is often confused with them due to its similar feeding habits. It targets animal-based products, particularly in dark, undisturbed areas, and is commonly found in homes and warehouses.
​
Conclusion
Larder beetles can be a difficult pest to control due to their ability to hide in hard-to-reach places and their preference for dark, secluded areas. Early detection and proper food storage practices are essential to preventing an infestation. Professional pest control services are the most effective solution to eliminating larder beetles and ensuring your home or business remains free from these destructive pests.
Signs of a Larder Beetle Infestation
Detecting a larder beetle infestation early can significantly reduce the damage to your property. Here are common signs that may indicate their presence:
Regular sighting of small beetles in storage areas
If you frequently spot small brown beetles inside your home, particularly in the kitchen, pantry, or near food storage areas, it could be a sign of an infestation. Occasional sightings of a single insect are not usually a cause for concern, but repeated appearances should raise alarms about a potential infestation.
​
Presence in dark, isolated areas
Larder beetles prefer to hide in dark, quiet spaces. They are commonly found in cracks in walls, the corners of pantries, or inside improperly sealed containers. If you notice multiple beetles in these areas, it's an indication they have found an ideal environment to breed and thrive.
​
Visible damage to stored products
Larder beetles primarily target stored animal products, such as dried meats and furs. If you notice signs of damage to these food items, like holes in packaging or unusual residue, it could be due to beetle activity.
​
Finding dead beetles near infested areas
It is not uncommon to find dead larder beetles near cracks, baseboards, or corners, especially when the infestation is well-established. This should prompt a more thorough inspection of your food storage areas.
​
Increased activity around stored food
If you see a rise in beetle activity around your food storage, such as dried meats or similar items, it means the beetles have found a consistent food source to sustain their population. Increased activity in these areas is a strong indicator of an infestation.
​
Larvae hidden in stored food
The larvae of larder beetles are often difficult to see, but they are typically found in improperly stored food. A careful inspection of open packages or corners of storage areas can sometimes reveal these larvae in development.
​
Repeated issues with food supplies
If you notice that your dried meats, furs, or other stored animal products are frequently damaged or contaminated, it's likely due to the presence of larder beetles. Ignoring these signs can lead to widespread contamination of your food stock.
​
Conclusion
Being alert to these signs can help you take quick action and prevent a severe infestation of larder beetles. If you notice these indicators, it’s important to act promptly to limit the extent of the problem. In more severe cases, a professional pest control service can effectively handle the situation, especially when the infestation has reached difficult-to-access areas.
Understanding Larder Beetles
Larder beetles are invasive pests that can easily slip into a property, particularly in kitchens, attics, and storage areas. They prefer dark, undisturbed places like wall cracks, forgotten cupboards, and storage boxes. Drawn to animal-based materials such as dried meats, furs, and certain fabrics, they feed quietly while causing significant damage to food supplies and stored belongings. Their presence often remains unnoticed until clear signs appear, such as larvae found in food items or visible damage to materials. If not addressed promptly, a small problem can quickly grow into a widespread infestation that becomes much harder to control.
The Problem with Larder Beetles Infestations
One of the major challenges with larder beetles is how easily they can invade a property without being noticed. These insects tend to seek out dark, quiet spaces like pantries, attics, or basements where they can feed on a wide range of organic materials, including dried meats, animal products, and even fabrics. Cracks in walls, storage boxes, and hidden crevices provide ideal conditions for them to thrive and reproduce. While a few beetles may not seem alarming at first, their numbers can grow rapidly if the infestation is ignored, leading to widespread damage to both food supplies and valuable belongings.
​
Homeowners often try to control larder beetle problems using basic traps or readily available insecticides, but these methods usually offer only temporary results. Most quick fixes tend to eliminate the adult beetles without addressing the hidden larvae or the secluded egg-laying sites. Without a complete and thorough treatment strategy that reaches deep into their nesting areas, infestations tend to persist and worsen over time. To truly resolve the issue and prevent it from coming back, professional intervention is necessary, targeting every stage of the larder beetle life cycle for lasting protection.
