One of my neighbors, two streets over, got bitten by several brown recluse spiders in NC, just north of Charlotte. He had to wear an antibiotic pack on his hip to give him antibiotics for six weeks. First bite was from a spider in his shrubbery bed and then the second and third bites were from some hidden in his closet.
NC is right on the edge of its normal range and partially included in fact so that’s not surprising at all. Oregon is nowhere near the normal range.
