I shelter and protect my wolfies whenever I see them, and I've not seen hardly any BW or BR spiders in about ten years. And this, even though my bedroom is in the basement!Yep, and thankful for that. They can eat all of the black widows they want.. outside. And we do have a lot of those. My son sprayed all along our driveway up against the house. Killed a mama and her little black widow babies.
