In order to find this spider in its natural habitat, the first place to start looking is beneath rocks and inside tree holes. This arachnid, however, benefits itself from the human contact ; this type of animal relationship is called "synantrophic". Since the spider has nocturnal habits, the human artificial light attracts them because of the large number of insects that are normally gathered around the light bulbs, and so the brown recluse spider ends inside your home in search for them.
The brown recluse has no interest in humans whatsoever; its bite is always "unintencional", which means the arachnid will only bite when being threathened or accidentally touched. More of this subject using the menu on the left.
