Charleston's Complete Guide To The Black Widow Spider


October 15, 2020

On a scale from one to ten, how scared would you say you are of spiders? It’s fair to assume most individuals would fall in the six to ten range and that only a small percentage of people aren’t afraid of spiders at all. Regardless of how you feel about spiders, there is one spider you should always be fearful of, the black widow. To help you better understand these dangerous house pests, here is a detailed guide on black widow spiders.

What Are Black Widow Spiders?

Black widow spiders got their name for the common misconception that they always eat their mates after breeding. The truth is, black widows will only occasionally consume their partners. In the United States, there are five species of black widow spiders. The best way to identify a black widow, regardless of the species, is by the red hourglass figure on their abdomens.

As spiders go, black widows are large, often growing to be over an inch and a half long. This size, however, does not stop them from weaving and living in irregular and messy webs. Inside homes, these webs are found low to the ground, usually where foot traffic is less common. Silken web sacks are a great way to identify a black widow infestation within your home. If you suspect black widows have entered into your home, regularly check around doorways for these egg sacs.

The Dangers Of Black Widow Spiders

There are only two species of dangerous spiders here in South Carolina, the brown recluse and the black widow. Both of these house pests possess venom potent enough to kill small animals and severely hurt humans. The venom of a black widow produces symptoms including muscle cramps/spasms, sweating, chills, nausea, vomiting, headaches, restlessness, shock, stupor, as well as severe back, belly, and chest pain. Black widow bites are rarely fatal but do take human lives from time to time. Children, the elderly, and individuals with preexisting medical conditions are at increased risk from these dangerous pests.

If a black widow bites you, seek out medical attention immediately. A medical professional will be able to assess your risk and minimize painful symptoms.

How To Prevent Black Widow Spiders

Black widow spiders invade homes to either hunt for insects or to seek shelter from unfavorable weather conditions. To keep black widows out of your Charleston home, here are the best prevention tips our experts have to offer.

  • Using a caulking gun or liquid cement, seal gaps, cracks, and holes in your home’s exterior foundation.
  • Repair or replace damaged door sweeps.
