The black widow is reclusive and not aggressive, but they can and do bite. At best, the bite produces pain and swelling, and can cause death. Reclusive does not mean harmless. In fact, we also have here a small spider called the "brown recluse;" its bite sometimes results in a large patch of disintegrating flesh, and sometimes in death.No, nothing like that.
It was easy to handle, not aggressive at all. I made it walk on my hand and my arm, and then again I dropped her off on the floor.
Other spiders are even reclusive, they try to run away quickly.
Only south American bird spiders and Tarantulas are aggressive. They'd probably snatch.
