Are Brown Recluse Spiders In Memphis, TN Dangerous?

October 15, 2021

Brown recluse spiders (Loxosceles reclusa) are widely feared due to their venomous bites. However, this spider is not aggressive and prefers to hide, and most bites are caused by physical injury to the spider, I.e., rolling over on the spider or putting on a shirt the recluse is hiding in.

What Do Brown Recluse Spiders Look Like?

The brown recluse varies from light to dark brown, with most light to moderately brown. There is a darker marking in the shape of a violin on the carapace, the part the three pairs of eyes are on. The spider's body is ¼ to ½ inch long and 1/8 to ¼ inch wide. The whole spider is about the size of a quarter up to a half-dollar.

Where Do Brown Recluse Spiders Live and Hide?

These spiders preferred dry, sheltered areas. Outside, they hide under loose stones, bark, and in hollow logs.  In houses, they find dark, quiet corners in the basement or garage, cabinets, back closets, and attics. Sometimes they nest under beds or other furniture that is rarely disturbed. 

Lifecycle Of The Brown Recluse Spider 

The brown recluse spider makes an egg sac and lays 20-50 eggs inside, which hatch in three to five weeks. The spiderlings stay in the web with the female for the first one to two molts and then disburse to other places. It takes six to seven molts and close to a year before the spiderling is an adult. The female may make five egg sacks in the two or so years she lives. 

Medical Dangers Brown Recluse Spiders Cause 

Brown recluse spiders have long enough fangs to break human skin and a potent enough venom to cause a problem. The initial bite is painless, but within six to 12 hours, it forms a blister and an irregular red area forms around it. The tissue breaks into smaller blisters, and then the tissue dies. The resulting ulcer heals slowly and may need skin grafts or other treatment. Deaths have been recorded but are not common. If you think a brown recluse has bitten you, seek medical treatment immediately. 

Preventing Brown Recluse Spiders 

Brown recluse spiders come into homes looking for food and shelter. If you do not have other pests for the spider to eat, there will be no need for the brown recluse to stay in your Memphis home. Here are some tips to keep them outside where they belong:

  • Eliminate prey species in the house.
  • Caulk cracks in the foundation and walls.
  • Caulk around the openings where pipes, electrical wires, and cables enter the house.
  • Make sure bedspreads and bedsheets do not touch the floor.
  • Remove debris and objects from the yard.
  • Clean up the clutter in the home.
  • Vacuum in the back of closets, basements, cupboards, and other dark, sheltered places regularly.
  • Make sure window screens and door screens are tightly fitting and do not have any holes in them.
  • Make sure door sweeps are in good condition.
  • Shake out shoes and clothes before putting them on.
