I am really sorry for all of your experiences with brown recluse bites
I just wanted to point out that they are not aggressive, and won't just attack you for no reason. So, if you see one somewhere out in the woods (is that where they live?), there is probably no reason to kill it.
"As suggested by its
specific epithet reclusa (recluse), the brown recluse spider is rarely aggressive, and bites from the species are uncommon. In 2001, more than 2,000 brown recluse spiders were removed from a heavily infested home in Kansas, yet the four residents who had lived there for years were never harmed by the spiders, despite many encounters with them.[SUP]
[13][/SUP] The spider usually bites only when pressed against the skin, such as when tangled within clothes, towels, bedding, inside work gloves, etc. Many human victims report having been bitten after putting on clothes that had not been worn recently, or had been left for many days undisturbed on the floor. However, the fangs of the brown recluse are so tiny they are unable to penetrate most fabric"
