How do you get rid of black widow spiders?
I saw a black widow in my yard and their was 3 egg sacks!
Watch out for those things. You most certainly do not want to get bitten by one! Get a spray treatment specifically for spiders, and blast 'em from a safe distance. Keep kids and pets away from the area. Clean up anything lying around that would be inviting for black widows. They seem to like cool, dark places, so get rid of nesting areas. But be very careful in doing so! Again, the bite from a black widow is no joke! Good luck!
