we have a lot of black widows around our area. I have a terrible reaction to spider bites (I wrote bikes instead of bites first, must miss home). I have scars from bites and have had these nodules removed by my doctor. And I swell. It is not good. Yet I still try and put them outside or in another part of the yard. But I have been known to step on them. Guess it depends on what kind of day I am having.
