I have gone on the offensive in regards to getting rid of the Black Widows around my property. I don't like using insecticide sprays, but I also don't like the idea of one of my children getting bitten by North America's most poisonous spider. So today, I sprayed every single cob web in my rock garden, and sure enough, every single one contained a Black Widow.
I killed EIGHT just today, and I am now wondering if this is a problem I can take care of.
Even the small webs that I felt sure didn't belong to a Widow; sure enough, after a few minutes one came crawling out.
All these pictures were of course taken when they were dead, as I certainly wasn't concerned about getting a picture when they were alive! I think Dave believes I am either exaggerating the problem, or that there isn't a problem; since he asked me the other day if I was sure I was really killing Black Widows, as, "You know that there are other spiders with red spots." Well now I have picture proof. I also know more about Black Widows (their webs, egg sacks, habits, habitation, etc.) than I ever would have if we didn't have so many of them.
