SPIDER BEETLE EXTERMINATOR - MONTREAL & SOUTH SHORE
About Spider Beetles (Attagenus spp.)
Activity
Spider beetles are generally active year-round, though their presence often peaks during the warmer months. These insects are most active during nighttime, seeking out dark, undisturbed spaces like cracks in furniture, walls, or storage areas. They tend to avoid bright and busy areas, remaining hidden during the day and emerging more frequently at night to feed. In colder weather, spider beetles may slow down their activity but can still survive indoors where the conditions are warmer and more conducive to their survival.
​
Diet
Spider beetles are opportunistic feeders, consuming a variety of organic materials. Their diet mainly consists of wood, paper, and stored food products, but they are particularly attracted to items with high starch content or decaying matter. Unlike some pests, they do not feed on living organisms, but rather on dried and damaged organic material. If spider beetles are present, it’s often because they have found an ample food source to sustain their population.
​
Size
Spider beetles are small, ranging from 1.5 to 6 millimeters in length, with some species being even smaller. Their bodies are oval and often covered in fine hairs, which can make them appear fuzzy. Their size, combined with their ability to hide in narrow cracks and corners, makes them challenging to detect. Their small size allows them to infiltrate areas like kitchen cupboards, food storage spaces, and wooden furniture without being easily noticed.
​
Habitat in Quebec
Spider beetles can be found throughout both urban and rural areas in Quebec, especially in places with a lot of stored organic materials or old furniture. Inside homes, they are often found in basements, attics, or hidden corners of kitchens and pantries. Outdoors, spider beetles may infest woodpiles or areas with stored food items that have been neglected or improperly sealed.
​
Inside buildings
Although spider beetles tend to avoid well-lit, busy areas, they are commonly found in dark, undisturbed spaces inside homes. Kitchens, food storage areas, and places with older wood structures, like attics or basements, are prime locations for these pests. They thrive in environments where organic matter is present, whether it’s in the form of old cardboard boxes, books, or forgotten food.
​
Outside structures
Outdoors, spider beetles can often be found in woodpiles, old furniture, or discarded plant materials. They are drawn to areas with a high concentration of organic matter. While they do not breed outdoors in the same way mosquitoes do, their presence in outdoor storage areas can lead to infestations when they find their way indoors, especially in improperly sealed or neglected structures.
​
Breeding Preferences
Spider beetles breed in dark, quiet, and secluded spaces where organic materials are available for feeding. They lay their eggs in areas rich in food sources, like old wooden furniture, storage boxes, or dried out plant matter. The larvae hatch and feed on these materials, growing into adults over time. Unlike mosquitoes, spider beetles do not require standing water to reproduce, making them more adaptable to various environments.

Common Spider Beetle Species in the Montreal Area
​
Furniture Spider Beetle (Anobium punctatum): This species is commonly found in old, wooden furniture and can cause significant damage to antique pieces. It prefers dry, undisturbed spaces and is typically found in older homes or places where wood is left untreated or exposed to moisture.
​
Flour Beetle (Tribolium castaneum): Often found in food storage areas, this beetle feeds on dried goods like flour, grains, and spices. It is known for its ability to thrive in a variety of conditions and can easily infest kitchens and pantries.
​
Wood-Boring Spider Beetle (Ptinus fur): Typically found in wooden furniture, woodpiles, and bookshelves, this species feeds on wood and is often the culprit behind the deterioration of old furniture. It can also infest food products if not managed properly.
​
Spider beetles can be difficult to control once they’ve found a food source. Their ability to hide in hard-to-reach areas and reproduce without the need for water makes them a year-round concern. Regular inspections and early detection are key to preventing infestations, while professional treatment can help eliminate the problem and restore the integrity of your home or business.
Signs of a Spider Beetle Infestation
Detecting a spider beetle infestation early can help prevent extensive damage to your property. Here are the common signs that may indicate their presence:
Frequent sightings of spider beetles indoors
If you notice spider beetles regularly inside your home, especially in areas such as kitchens, pantries, or storage spaces, it could suggest an infestation. A single beetle may not be concerning, but consistent sightings signal that there may be a larger problem nearby.
​
Concentration in hidden or dark spaces
Spider beetles prefer to hide in dark, concealed spots such as cracks, corners, or behind furniture. If you find clusters of beetles in places like cracks in the walls, wooden beams, or storage containers, it’s an indication that they have found a safe place to thrive.
​
Presence of damaged materials
These beetles feed on organic materials like wood, books, or dried food. If you notice signs of damage, such as small holes in wooden furniture, books, or food packaging, spider beetles may be the cause.
​
Small black or brown beetles found dead indoors
Finding dead spider beetles, especially near cracks, crevices, or doors, may indicate that they have been active in the area. It’s important to take note of this recurring issue as it could point to a hidden infestation.
​​
Excessive beetle activity around wooden items or food storage
These beetles are drawn to organic materials, especially dried food products or wood. If you observe more beetles near wooden furniture or food containers, it may be time to inspect for an infestation.
​
Presence of larvae or eggs in storage areas
Spider beetle larvae can often be found in areas where food or wood products are stored. These tiny larvae may be hidden in packaging or under the surface of the materials they are feeding on. Finding them should prompt a closer inspection.
​
Repeated damage to stored food or wood products
If food items in your pantry or books in your shelves have been repeatedly damaged or seem to have holes or discoloration, spider beetles are likely feeding on them. Immediate action is necessary to prevent further destruction.
​
By promptly responding to these warning signs, you can effectively manage and eliminate spider beetle infestations before they cause more significant harm. In some cases, professional treatment may be needed to fully eradicate the problem, particularly when the beetles have spread to hard-to-reach areas.
Understanding Spider Beetles
Spider beetles, or members of the Anobiidae family, can quickly infest a property, whether inside homes, warehouses, or food storage areas. These insects, often elusive, hide in cracks, corners, or stored items like furniture and boxes. Attracted to warmth and organic materials, they feed on substances like wood, paper, and sometimes even food products, causing significant damage. Their presence is often unnoticed until visible signs of their activity appear, which can lead to large infestations. Although their behavior is subtle, these insects can turn a previously peaceful environment into a source of concern, as their damage can affect both structures and personal belongings.
The Problem with Spider Beetle Infestations
One of the primary challenges with spider beetles is how easily they can infest a property without being noticed. These small pests often hide in dark, quiet spaces such as pantries, basements, or storage areas, feeding on organic materials like food scraps or textiles. A few overlooked hiding spots—like cracks in furniture, stored boxes, or neglected corners—can quickly become breeding grounds for spider beetles. Their presence might initially seem insignificant, but over time, they can cause significant damage to food items, fabrics, and other materials.
​
Many people attempt to manage spider beetle infestations using home remedies or store-bought sprays, but these methods typically offer only temporary relief. Most DIY solutions target the visible beetles but fail to address the underlying issue: the larvae and eggs that are hidden in hard-to-reach areas. Without a thorough inspection and proper treatment of breeding sites, the infestation is likely to return. For a lasting solution, a professional approach is necessary—one that not only eliminates adult beetles but also addresses their breeding spots to prevent future infestations, ensuring your property remains safe from these damaging pests.
Our Approach to Spider Beetle Control
Dealing with a spider beetle problem requires a thoughtful and detailed approach. Although these small creatures are often discreet, they can cause significant damage if they invade areas such as pantries, closets, or storage spaces. Spider beetles primarily feed on organic matter, such as food remnants, and can damage valuable items like textiles or books. Home remedies, such as traps or repellents, typically do not address the root cause of a spider beetle infestation effectively.
​
Our approach begins with a thorough inspection of the property to identify areas conducive to spider beetle infestations. This includes checking food storage, furniture, and spaces like attics or basements. Once the hotspots are identified, we assess the conditions that attract these pests, such as humidity or the accumulation of organic debris. This diagnosis is crucial for developing a tailored solution to effectively eliminate spider beetles.
​
Our treatments are designed to target both the adult beetles and their larvae. In addition to applying specific products to the problem areas, we offer advice on reducing conditions that encourage their development, such as improving ventilation and removing moisture sources. With this comprehensive approach, you can restore a healthy environment, free from spider beetles, without worrying about further damage.
