Spider beetles are small, black to reddish-brown beetles primarily from the family Ptinidae. They are generally 1-7 mm in length with an oval shape and long legs. Their head is bent downward and their antennae are long and thin. Spider beetles often have a pattern of stripes or spots on their backs. They may have wings, although they rarely fly. There are several species of spider beetles, including: Ptinus fur, Ptinus tectus, Mezium affine, Mezium Americanum, Mezium Columbianum, Dienerella filum, Dienerella mutabilis, Ammoblia insularis, Ammoblia granulata, Ammoblia opaca, and Ammoblia terricola.
Signs of Spider Beetle Infestation
Spider beetles are small, round insects that feed on organic materials such as grains, flour, cereals, spices, and dried fruits. They may also infest animal products like furs, hides, and feathers. These pests are easily identified by their small, oval, reddish-brown bodies. They have long, thin antennae and short legs. They are usually less than 1/4 inch in size.
Common signs of a spider beetle infestation include the presence of the beetles themselves, webbing on the infested materials, and small, round fecal pellets. The webbing is usually thin and white, and can be found on the surface of infested items. The fecal pellets are a major sign of an infestation, as the beetles feed on the materials and then excrete them. The pellets are small and round, about the size of a pinhead.
Spider beetles may also cause damage to the infested materials. This can range from small holes to large chunks being eaten away. Spider beetles usually feed in small, concentrated areas, so the damage may be localized. In addition, the beetles may also leave behind a musty odor, which is another sign of an infestation.
If you suspect a spider beetle infestation, it is important to take action quickly to avoid further damage. Vacuuming can help to remove the beetles and their webbing, as well as their fecal pellets. It is also important to inspect the infested items for damage and dispose of any materials that are too damaged to be saved.
Prevention of Spider Beetle Infestations
- Reduce clutter in the home to reduce hiding places for spider beetles.
- Regularly vacuum carpets, rugs and upholstered furniture.
- Store food in sealed containers.
- Check for infested items when bringing new items into the home.

Treatments for Spider Beetle Infestations
- Vacuuming: Vacuuming is an effective way to remove spider beetles from carpets, rugs, and other upholstered furniture. Vacuuming should be done on a regular basis to remove any beetles and their eggs.
- Insecticides: Insecticides can be used to control spider beetles. However, these products should be used with caution, as they can also be toxic to humans and pets. It is important to read and follow the directions on the label carefully.
- Traps: Spider beetles can be trapped with insect light traps and glue traps. The traps should be placed in areas where the beetles are active, such as near windows and doors, and in dark corners.
- Pesticide Dusts: Pesticide dusts are an effective way to control spider beetles. Dusts should be applied in areas where the beetles are active, such as baseboards, window frames, and other cracks and crevices.
- Sanitation: Good sanitation is important in controlling spider beetles. This includes regularly cleaning and vacuuming furniture and carpets, as well as disposing of garbage and food waste properly.
Biological Control Strategies for Spider Beetles
| Strategy | Details |
| Predators | Predators such as spiders, centipedes, and mites are natural enemies of spider beetles, and can help reduce their populations. |
| Parasites and Pathogens | The parasitic wasp Tetrastichus julis is a natural enemy of spider beetles. This wasp lays its eggs inside the beetle larvae, killing them. There are also several fungal pathogens that can be used to control spider beetles, including the fungus Metarhizium anisopliae. |
| Biological Insecticides | Biological insecticides such as Bacillus thuringiensis (Bt) can be used to control spider beetles. These insecticides use bacteria to kill the beetle larvae, and can be applied as a spray or dust. |
Biological control strategies are an effective way to reduce spider beetle populations without the use of chemicals. By introducing natural enemies such as predators and parasites, or using biological insecticides, it is possible to reduce the number of spider beetles in an area.
Chemical Control Strategies for Spider Beetles
- Apply insecticide dusts or aerosols. These products contain pyrethrins, permethrin, or other active ingredients which can be used to control spider beetles.
- Spray areas that are prone to spider beetle infestations with an insecticide. Common active ingredients include bifenthrin, cyfluthrin, lambda-cyhalothrin, and permethrin.
- Apply an insect growth regulator such as diflubenzuron or novaluron to areas that are likely to be infested. These products disrupt the molting process, preventing spider beetles from reaching adulthood.
- Treat cracks and crevices with an aerosol insecticide such as pyrethrins or permethrin.
- Treat areas that are likely to be infested with a residual insecticide such as bifenthrin, cyfluthrin, or lambda-cyhalothrin.
Non-Chemical Control Strategies for Spider Beetles
- Clean the infested area regularly and thoroughly. Vacuum carpets, furniture, and clothing to remove spider beetle eggs, larva, and adults.
- Wash any infested clothing in hot water and dry at the highest heat setting.
- Reduce clutter in your living space as spider beetles may hide in it.
- Ensure there is good air circulation in your home.
- Seal any entry points to your home with caulk or other materials.
- Check stored food containers for signs of infestation.
- Introduce natural predators to your living space, such as spiders, centipedes, or ladybugs.
- Use pheromone traps to attract and capture adult spider beetles.
- Install yellow or blue sticky traps in areas where you have noticed spider beetle activity.
Frequently Asked Questions
What are the signs of a spider beetle infestation?
Spider beetle infestations can be identified by the presence of small, dark-brown or black beetles found in food and grain products. These beetles are typically 1-3 mm in size and have a distinctively elongated shape, resembling spiders. Other signs of an infestation include larvae, shed skins, and fecal pellets. In addition, you may notice damage to your food, as spider beetles will feed on grains, cereals, dried fruits, nuts, and spices.
What are the most effective methods for controlling a spider beetle infestation?
The most effective methods for controlling a spider beetle infestation include sanitation and exclusion, use of insecticide baits, and insecticide sprays. Sanitation measures include removing potential food sources, such as stored foods, pet food, and birdseed, and eliminating clutter where beetles can hide. Exclusion measures involve sealing cracks, crevices and other potential entry points. Insecticide baits containing boric acid or other insecticides can be used to control spider beetle infestations. Insecticides can also be applied as a spray to areas where the beetles are active.
What precautions should be taken when dealing with a spider beetle infestation?
Prior to any action, it is important to identify the species of spider beetle present in the environment. The best way to do this is by using a magnifying glass and/or a microscope to closely inspect the areas of infestation. It is also important to keep the infested area clean and dry, as spider beetles thrive in moist and dusty places. Vacuuming the area and removing any food sources or clutter can help reduce the number of spider beetles present. If insecticides are used, it is important to select one that is labeled for spider beetle control and to follow the directions on the label carefully. Additionally, it is advisable to seal off any entry points in the home to prevent future infestations.
How can I prevent future spider beetle infestations?
To prevent future spider beetle infestations, store food items in sealed containers and regularly discard old food, especially if it is stored for a long time. Vacuum and dust regularly to remove any potential spider beetle eggs and larvae. Seal any cracks or crevices in walls and floors where the beetles can enter. Keep the humidity level in your home low, as spiders beetles thrive in moist environments. Regularly inspect any new items brought into your home, as these can be carriers of spiders beetles.
Are there any natural remedies for controlling spider beetle infestations?
Natural remedies such as essential oils, diatomaceous earth, and boric acid can be used to help reduce spider beetle infestations. Essential oils like peppermint and lavender can be used to repel and kill the adult beetles. Diatomaceous earth is a powder made of fossilized diatoms that can be used to coat surfaces and create an inhospitable environment for the pests. Boric acid is a naturally occurring mineral that can be used as a direct contact insecticide.
