Brown Recluse Spider: Identification and Extermination

The Brown Recluse spider, scientifically known as Loxosceles spp., is a venomous spider species that is known for its potentially harmful bite. In this comprehensive guide, we provide valuable information about the Brown Recluse spider and offer insights into effective techniques for managing their presence, if necessary. Brown Recluse spiders are primarily found in the central and southern regions of the United States. They have been reported in states such as Texas, Oklahoma, Kansas, Missouri, Arkansas, Louisiana, Mississippi, Alabama, Georgia, Tennessee, Kentucky, Indiana, and parts of Illinois. However, it’s important to note that their distribution may vary within these regions and may extend to neighboring states as well. Understanding the geographic range of Brown Recluse spiders can be helpful in assessing the potential risk of encountering them in specific areas.



Identifying Brown Recluse spiders is crucial for proper management. Key characteristics include:

  • Size: Adult Brown Recluse spiders typically range from 6 to 20 mm in body length, with long legs that are uniformly light to dark brown.
  • Violin-Shaped Marking: Distinctive Markings: Brown recluse spiders are identified by the characteristic dark brown violin-shaped marking on their cephalothorax (the body part to which the legs are attached). This marking, known as the “violin pattern” or “fiddleback,” is one of the key features used to distinguish them from other spider species.
  • Six Eyes: Unlike most spiders, Brown Recluse spiders have only six eyes arranged in pairs.
  • Web Construction: Unlike many other spiders, brown recluse spiders do not spin elaborate webs for capturing prey. Instead, they construct irregular, messy webs as retreats or to aid in their hunting activities. These webs are often found in corners or secluded areas and are not used for prey capture like the orb-weaving spider webs.


Brown Recluse spiders are predominantly nocturnal and prefer undisturbed areas such as basements, attics, and closets. They are reclusive by nature and typically hide in dark corners, crevices, and cluttered spaces. Brown recluse spiders are native to the United States, primarily inhabiting regions in the central southern states. They prefer warm and dry environments and are commonly found in areas with cluttered surroundings, where they can find ample hiding places. These spiders are not aggressive and generally bite when unintentionally provoked, such as when trapped against the skin or pressed against bedding or clothing. It is recognized for its potentially harmful bite, which can cause a range of reactions in individuals. While the majority of bites result in mild symptoms, some individuals may experience more severe reactions requiring medical attention. When dealing with the presence of Brown Recluse spiders, caution should be exercised, and consulting professionals experienced in effective extermination techniques is advisable. Implementing preventive measures, such as decluttering and sealing potential entry points, can also help minimize encounters with these spiders.
