in his Tues science Times a "bug guy" related his tale of being bitten by a black widow and having gone through a new antivenom trial as a result. He was from New Jersey and recounted the explosion of the most common of the widow species, Latrodectus nactans on the East Coast of US. They make really messy webs (unlike the works of art of the yellow garden spider). The reporter told of having gone around smashing widows so his kids wouldn't get but (A kid could die from the bite), So his story of his bite was putting on a pair of work boots from a closet(boots he didn't wear for a while) and, after walking a few feet, feeling this stabbing pain on his big toe.
He said that, after the venom settled in, the overall pain was excrutiating.
When I get home Im gonna sweep for widows as they overwinter.
