Help Identify Spiders and More

These reader reports and photos were collected over sixteen years of bite discussions on this page. Warning: Some of these pictures may show a scary spider or a bite that has become infected and could be considered disturbing to some, so if you don’t like the sight of rotted skin or exposed bone, this may not be for you. However, it does drive home the importance of seeking medical attention before it’s too late! Want to compare more photos? Start with our spider bite photo library.

Reader Bite Reports: Six Cases From the Archive

Sixteen years of bite reports came through this page. These six, condensed and attributed by first name, cover the range from mild to nearly losing a finger. The pattern across all of them: the bite itself was rarely the problem. The infection afterward was, and speed to a doctor decided how each story ended.

Claire: the mild one

Small raised bite on Claire's neck

Claire came home from Florida with an itchy raised bump on her neck and a smaller rock-hard one at her hairline. When her throat started feeling sore she saw a doctor, who called it a bug bite, likely spider, recommended topical Benadryl, and wrote an antibiotic prescription to fill only if it got worse. It never did. Most bites end exactly like this, and hers is here so the ones below stay in proportion.

Christina: the textbook response

Blister forming on Christina's heel

Christina felt a light sting on her heel carrying groceries in at night, and by morning pain was shooting up her leg. She was in the ER less than 12 hours after the bite. Antibiotics, steroids, ice in 15-minute stretches, no heat, and firm instructions not to pop the quarter-sized blister. It broke on its own on the ninth day and healed clean, and she credits going in fast for how easily she got off.

Lindsey: the hole between her eyes

Wound between Lindsey's eyes after the scab fell away

Lindsey woke with a swollen red area between her eyes, watched a red line crawl down beside her nose, and then watched the blackened center fall away and leave a hole. Doctors put her on antibiotics, scraped the wound to restart healing blood flow, and lined up a surgeon consult for the scar. Her advice is the page’s advice: discoloration or a traveling red line means medical attention, now.

Leah: a week of hospital visits

Leah's lanced bite wound on her arm

What Leah took for a wasp sting became a rock-hard, ping-pong-ball swelling with a red line running toward her elbow. The hospital lanced it, put her on IV antibiotics three times a day for a week, and finally removed the infection’s capsule, a white sac the size of half a cotton ball. The red line faded almost immediately after. That sac was not something the spider left behind; it was the wall her body built around the abscess, and it is why deep infections need a doctor’s hands, not a squeeze.

Jack: the site talked him into going

Jack posted a photo of a small bite on his cheek that had ballooned overnight, and the site’s answer at the time was blunt: nothing near an eye is worth gambling on. He sent the photo to his doctor from a business trip, got diagnosed with cellulitis, a skin infection likely seeded by the bite, and started a strong antibiotic the same day. The doctor’s postscript stuck: waiting the weekend had been a mistake, and one more day would have meant fever and a much worse week.

Allen: one squished spider, one saved finger

Allen's finger healing after surgery

Allen mashed a small black spider with white spots in an ice chest and thought nothing of the tiny mark on his finger. Five days later a surgeon was scraping infected tissue out of it and telling him he had been an hour of hesitation from amputation. Four days on IV antibiotics and weeks of physical therapy later, he got nearly all the motion back. The spider, from his description, was probably a harmless jumping spider. The infection did not care.

If your bite looks like any of these, our spider bite treatment page covers first aid and the warning signs, and the bite identification chart helps you sort spider from staph from bed bugs.
