Two of the most medically significant spiders in the U.S. are the Black Widow and Brown Recluse. While their bites are rare, both can cause serious symptoms that require prompt medical care.

Brown Recluse: Light to dark brown with a violin-shaped mark on the back. Prefers dark, undisturbed places. Bites can start painless but may develop into severe tissue damage (necrosis), fever, and chills. Black Widow: Glossy black with a red hourglass marking on the abdomen. Females are larger and more likely to bite when threatened. Bites may cause intense pain, muscle cramps, nausea, and breathing difficulty within an hour.

What to Do If Bitten
Stay calm to slow venom spread.
Clean the bite with soap and water.
Apply a cold compress to reduce swelling.
Limit movement of the affected limb.
Seek medical attention immediately.
Treatment Options
Black Widow: Severe cases may require antivenin, pain relief, and muscle relaxants.
Brown Recluse: Treated with corticosteroids, antibiotics, and sometimes surgery for necrotic tissue. Avoid home remedies like applying heat or sucking the venom.

Declutter and clean dark corners and storage areas.
Shake out clothes, shoes, and bedding before use.
Wear gloves and long clothing when working in garages or sheds.
