Black Widow Spider

A serious but often misunderstood spider found around homes and structures in Eastern North Carolina

Scientific Classification

  • Order: Araneae

  • Family: Theridiidae

  • Scientific Name: Latrodectus spp. (primarily Latrodectus mactans in North Carolina)

Overview

The Black Widow Spider is one of the most recognizable spiders in the United States and one of the few that pose a genuine medical concern. In Eastern North Carolina, black widows are commonly found around homes, outbuildings, crawlspaces, and commercial structures—especially in quiet, undisturbed areas.

An interesting fact: despite their reputation, black widows are shy and non-aggressive, and bites usually occur only when the spider is accidentally pressed against skin.

Common Hiding Areas in Eastern NC

  • Crawlspaces and foundation voids

  • Woodpiles and firewood stacks

  • Sheds, barns, and garages

  • Outdoor furniture and grills

Black widows prefer dry, dark, and undisturbed locations, which makes crawlspaces and storage areas ideal habitats.

  • Egg sacs (round, tan or off-white, papery texture)

  • Sightings of shiny black spiders in dark corners

  • Increased insect activity attracting spiders

Why Black Widows Are Around Your Property

Several factors common in Eastern North Carolina make properties attractive:

  • Abundant insect populations (food source)

  • Wood debris, clutter, and storage near structures

  • Crawlspace moisture and poor ventilation

  • Cracks, gaps, and entry points around foundations

Risks & Concerns

Health Risks

Black widow bites are rare but medically significant:

  • Severe muscle cramps and spasms

  • Abdominal pain

  • Nausea and sweating

  • Elevated blood pressure

Children, elderly individuals, and those with compromised health are at higher risk and should seek immediate medical attention if bitten.

Property Damage

Black widows do not cause structural damage, but their presence indicates underlying pest and habitat issues.

Prevention Tips

  • Reduce clutter in garages, sheds, and crawlspaces

  • Store firewood away from structures and elevated off the ground

  • Seal cracks, gaps, and foundation penetrations

  • Control insects that attract spiders

  • Use gloves when working in dark, undisturbed areas

Control & Treatment Options

DIY Limitations

  • Sprays often fail to reach hidden harborages

  • Killing visible spiders does not address egg sacs

  • Web removal alone does not eliminate the population

Professional Treatment Benefits
