Brown Recluse Spider

Loxosceles reclusa

Active:Active year-round in heated structures; peak activity in warmer months (March-October)

Brown recluse spiders are tan to dark brown with a distinctive dark violin-shaped marking on their back. They measure 1/4 to 1/2 inch in body length with legs extending total size to about 1 inch. Unlike most spiders which have eight eyes, brown recluses have six eyes arranged in pairs. These shy, reclusive spiders avoid human contact.

Habitat & Behavior

Brown recluses prefer dark, undisturbed areas and rarely venture into open spaces. They hide in closets, attics, basements, crawl spaces, behind furniture, in storage boxes, and within clutter. Outdoors, they inhabit woodpiles, sheds, and under rocks or debris. They build irregular webs in corners and hidden areas and are most active at night while hunting.

Signs of Infestation

  • Tan or brown spider with violin-shaped marking on its back
  • Irregular, loose webs in corners and undisturbed areas
  • Spiders in shoes, clothing, or bedding stored in closets
  • Multiple spiders in basements, attics, or storage areas
  • Shed spider skins in hidden areas

Health & Property Risks

Brown recluse venom contains a cytotoxin that destroys tissue and blood cells. Bites may initially go unnoticed but can develop into painful, necrotic lesions requiring medical intervention. Severe reactions include fever, chills, nausea, and in rare cases, systemic effects. Bites are most common when spiders are trapped against skin in clothing, shoes, or bedding. While brown recluses are not aggressive, their preference for hiding in human items increases encounter risks.

Prevention Tips

  • Reduce clutter in closets, basements, attics, and storage areas
  • Shake out clothing, shoes, towels, and bedding before use
  • Store items in sealed plastic containers rather than cardboard boxes
  • Seal cracks and crevices around doors, windows, and utility penetrations
  • Use yellow or sodium vapor light bulbs outdoors to reduce prey attraction
  • Keep beds away from walls and ensure bedding doesn't touch the floor

Professional Treatment Approach

Greenix's brown recluse control requires comprehensive treatment due to their reclusive nature. We conduct thorough inspections of potential hiding areas and apply residual insecticides to harborage sites including wall voids, attics, basements, and crawl spaces. We use crack and crevice treatments, dust applications, and glue traps to monitor and reduce populations. Multiple treatments are often necessary, combined with sanitation and exclusion recommendations to achieve long-term control.
