This video is of a jumping spider that found its way onto my monitor.
I was once bit by a brown recluse spider. I had a big welt on my arm for six months. In those days I killed all spiders and had to kill lots of flies and other bugs too. Now, I leave all jumping spiders and daddy long legs. They are safe to me, and they eat all the flies and bugs which makes me have nearly zero brown recluse food. So, a greatly reduced probability of brown recluse spiders.
