And I’m not saying they’re incapable of extending their normal range from time to time. I am just saying that 99 times out of 100, it isn’t a brown recluse north of its normal range.

Bugs and spiders migrate/hitchhike by being in boxes that are shipped or moved across the country.
Since the recluse is famous for being indoors, hiding in boxes and out of site, that is why they are spreading so rapidly.
They were originally found only in the southwest US.
I would not be surprised to see one anywhere.
