I live in an area where the Brown recluse is thick and contrary to what you may have heard, they are not that aggressive. while the bite is dangerous, unless they are attacking to eat, most of the time they inflict what's known as a "dry bite" ( no venom) most people don't know when they've bitten, and most doctors can't accurately decide if it was a fiddleback bite or not, without the spider to verify the species.
outside Kansas city a lady captured over 2,000 "confirmed" Brown recluse spiders in her house, and nobody in her house has ever been bitten.
Remember the Brown recluse spider is a wild species and like most wild animals, will flee rather than fight.
