Identifying it in Mississippi
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 carpenter ant bite, honey bee sting, fire ant sting — all of which are also recorded in Mississippi.
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

Season in Mississippi specifically
Records in Mississippi concentrate in May, June, July, October, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in Mississippi runs March to November.
Because woodpiles, sheds, meter boxes, garden furniture, under eaves — undisturbed dark corners, exposure in Mississippi 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.
Care
- wash the area and apply a cold pack
- seek medical care for anything beyond mild local pain — antivenom exists and pain control matters
- do not apply a tourniquet or attempt to cut or suck the wound
Avoiding them in Mississippi
- gloves when moving woodpiles, boxes or garden furniture
- shake out stored shoes and gloves
- reduce clutter in sheds and garages
