We are relatively new to NC and have come across several Black Widow spiders in our yard. While I know Black Widows rarely kill adults how concerned should we be about our kids (7 & 4) getting bit.
I often find black widows living under our gargabe cans and DEFINITELY in the wood pile or anywhere else there are dark "hidey" places. Inform your kids what they look like and tell them to steer clear. I've killed my fair share of them if they are in places I have to go daily (they love to hang out under the poles I use to build my jumps in my riding arena), but mostly I let them be.
