These spiders are found in various regions of the United States and, though generally non-aggressive, may bite when disturbed. Proper identification, swift first aid, and appropriate medical care are critical for effective management.
This guide provides accurate information on how to identify these spiders, what to do if bitten, and the best ways to reduce your risk of encountering them.
Identifying Dangerous Spiders
Black Widow Spider
The Black Widow spider, part of the Latrodectus genus, is distinguished by its shiny black body and a red hourglass marking on the underside of its abdomen. It prefers secluded, dark environments and is often found in garages, woodpiles, crawl spaces, and outdoor sheds. Females are more likely to bite and are significantly more venomous than males.
Symptoms of a Black Widow bite may include:
Local pain at the bite site
Muscle cramps and abdominal pain
Sweating and nausea
In rare cases, difficulty breathing or hypertension
According to the Centers for Disease Control and Prevention (CDC), symptoms usually begin within 30 to 60 minutes after the bite and can range from mild to severe depending on the individual’s age, health, and sensitivity to venom.
