Black widow spiders in Virginia
Yes — black widow spiders are recorded in Virginia. The GBIF biodiversity database holds 615 verified black widow spider records from the state — one of the highest counts in the country. Sightings concentrate in July to October. Onset: a sharp pinprick, then pain building over 30 to 60 minutes. Duration: symptoms usually settle within 2 to 3 days.

Black widow spider bites in Virginia: 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 paper wasp sting — all of which are also recorded in Virginia.
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
What else it could be in Virginia
These are recorded in Virginia too and are the ones most often confused with it here. The differences below are the ones that actually separate them.
| Black widow spider bite | Brown recluse spider bite | |
|---|---|---|
| Pattern | single site | single site |
| Where on body | hands, forearms, legs — usually where a hand reached into a dark space | torso under clothing, upper arms, thighs — often where clothing was put on with the spider inside |
| Appears | a sharp pinprick, then pain building over 30 to 60 minutes | often painless at first |
| Records here | 615 | 33 |
Black widow spider season in Virginia specifically
Records in Virginia concentrate in July to October, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in Virginia runs April to October.
Because woodpiles, sheds, meter boxes, garden furniture, under eaves — undisturbed dark corners, exposure in Virginia 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.

Counts are observations submitted to GBIF, not bites. They tell you when the animal is out and being noticed in Virginia; they do not tell you how many people were bitten. The thinnest month with any record at all is January (7).
How Virginia compares
Across the 37 states with any black widow spider records, Virginia ranks 4th with 615. The state directly above it is North Carolina (634). Directly below is Arkansas (467). The highest count anywhere is Texas (1,867).
Inside Virginia itself the picture is different again: of the 20 biting species we track with records here, this one is 8th and accounts for 3% of the 19,960 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.
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 black widow spiders in Virginia
- gloves when moving woodpiles, boxes or garden furniture
- shake out stored shoes and gloves
- reduce clutter in sheds and garages
