Both are common in Oklahoma. I was bitten by a recluse when I was 18. I’ve still got the dent in my arm from it. It took over a year to heal. Black widows are more rare. I was 65 before I saw my first one up close and personal. Needless to say she didn’t survive the encounter.They're all pretty safe around here too. Black Widows and Brown Recluses are said the be around here, but I've never seen any or know anyone who's been bitten.
