Black widow spider bites in South Carolina: what the mark looks like
The bite itself is unimpressive — a pinprick and two faint punctures. What identifies it is what follows: pain that spreads from the bite into large muscle groups, classically severe abdominal cramping that has been mistaken for appendicitis. The spider is identifiable by the red hourglass on the underside of a glossy black abdomen.
Locally, the species most often confused with it are honey bee sting, deer fly bite, lone star tick bite — all of which are also recorded in South Carolina.
Seek medical care if
- severe muscle cramps in the abdomen, back or chest
- sweating, nausea, rising blood pressure
- any suspected bite in a child, an older adult or during pregnancy — seek care

Black widow spider season in South Carolina specifically
Records in South Carolina concentrate in July to September, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in South Carolina runs March to November.
Because woodpiles, sheds, meter boxes, garden furniture, under eaves — undisturbed dark corners, exposure in South Carolina tends to be concentrated in specific places rather than spread evenly — which is why a bite history ("where were you in the 24 hours before?") narrows the answer faster than the appearance of the mark.

How South Carolina compares
Across the 37 states with any black widow spider records, South Carolina ranks 10th with 288. The state directly above it is Tennessee (289). Directly below is Maryland (265). The highest count anywhere is Texas (1,867).
Inside South Carolina itself the picture is different again: of the 19 biting species we track with records here, this one is 4th and accounts for 8% of the 3,723 records logged in the state. A species can be common nationally and marginal in one state, or the reverse — which is the whole reason this page exists separately from the national guide.
