Most New York City residents assume venomous spiders are somebody else’s problem. They’re not. The Northern Black Widow is native to New York State and has been found in Brooklyn basements, storage rooms, and the dark undisturbed corners of pre-war buildings across all five boroughs.
The Yellow Sac Spider — pale, small, and easy to dismiss — is also a resident venomous species in New York City, capable of delivering a bite that causes cramping, nausea, and in some cases localized tissue damage.
Then there’s the brown recluse. It doesn’t naturally live in New York, but it arrives here constantly — in moving boxes, shipped furniture, and packages from the South and Midwest where the species is common. New York City’s enormous volume of deliveries and the city’s massive annual apartment turnover each June and September make this a real, ongoing risk for anyone unpacking boxes or moving into a new unit.
Knowing which spider you’re dealing with changes everything about how it gets treated. That’s where we come in.
