Spider Beetle Bite: Facts and Treatment Tips

Spider beetles are small insects that resemble spiders. They are 1.5 to 3.5 millimeters in length and have a dark reddish-brown or black abdomen. Their heads, legs, thorax, and antennae are covered with pale yellow to cream-colored hairs. Spider beetles are primarily found in wall voids and drop ceilings, but they can also infest pantries. They feed on a variety of items including cereals, grains, seeds, dried fruits, and even dead insects and rodent droppings. While spider beetles can bite, their bites are not known to be harmful to humans or pets. However, they can infest and damage food products.

To get rid of spider beetles, it is important to locate and eliminate the source of the infestation. This can be done by inspecting food storage areas, disposing of infested foods, and storing food in sealed containers. Regular cleaning and eliminating other pests such as rodents and spiders can also help in preventing spider beetle infestations.

Key Takeaways:

  • Spider beetles are small insects that resemble spiders.
  • Their bites are not known to be harmful to humans or pets.
  • Spider beetles can infest and damage food products.
  • Inspect and clean food storage areas to prevent infestations.
  • Eliminate other pests like rodents and spiders to deter spider beetles.

Identifying and Controlling Spider Beetles

Spider beetles can be a nuisance in your home, especially in kitchens and pantries where they infest food products. To effectively address the issue, it’s important to identify these pests correctly and implement control measures. Here’s what you need to know:


Spider beetles can be recognized by their small size and spider-like appearance. The American spider beetle, for example, has a shiny, reddish-brown body with cream-colored legs and head. Whitemarked spider beetles have distinctive white patches on their wing covers. Another variant, known as smooth spider beetles, shares the same coloring as the American spider beetle but is smaller in size. These pests often leave behind webbing and cocoons in infested food, causing damage to fabric and packaging.

Signs of infestation to look out for include:

  • Holes in packages
  • Webbing in food
  • Silk cocoons

Control Measures:

Controlling spider beetles requires proactive steps to eliminate current infestations and prevent future occurrences. Here are some effective control measures:

  1. Clean up infested food: Remove and discard any infested food items immediately to prevent further spread.
  2. Vacuum pantry and cabinet shelves: Thoroughly clean and vacuum all shelves and cracks to remove spider beetles and their eggs.
  3. Practice good food storage habits: Store food in sealed containers to prevent infestations and maintain hygiene.
  4. Eliminate humidity: Spider beetles thrive in humid environments. Use dehumidifiers in the kitchen to create unfavorable conditions for these pests.

Insecticides can be used as a last resort if infestations persist despite preventive measures. However, it’s recommended to consult a pest control professional for expert advice on product selection and safe application methods.

Remember, early identification and prompt action are key to effectively controlling spider beetle infestations and protecting your home from further damage.

Preventing Spider Beetle Infestations

Preventing spider beetle infestations is essential to protecting your home and food from these pesky insects. By taking proactive measures, you can minimize the risk of spider beetle bites and protect your family and pets.

To prevent spider beetle infestations, start by removing their food sources. Store your food in sealed containers to make it inaccessible to these insects. This will help eliminate their food supply and discourage them from inhabiting your pantry or kitchen.

Another important step is to maintain proper hygiene in your storage areas. Regularly clean and sanitize your pantry and cupboard shelves, paying special attention to hard-to-reach places where spider beetles might hide. Vacuuming can be particularly effective in removing any remaining food residue or cocoons.

In addition to food storage and cleaning, it’s crucial to eliminate other pests that may attract spider beetles. Rodents and spiders are common hosts for these insects, so taking measures to control and prevent their presence can reduce the risk of spider beetle infestations.

If you have already taken preventive measures but still notice signs of spider beetles or suspect an infestation, it is recommended to seek professional pest control services. They can provide proper identification and effective treatment options to eradicate spider beetles from your home.
