I killed a black widow this evening as I was taking my dog Gretchen for her evening walk. The spider was where I always find--and kill--them: just outside the back sliding glass door.
About once a month, I'll kill a black widow and then it will be replaced by another. This has been going on for the ten years I've lived in this house, so I guess I've killed close to a hundred of these venomous creatures. Must be a prime feeding spot.
