I don't think that you need to be so fastidious
about counting eye spots, though that is a good
way to identify them. The violin shape on the
cephalothorax (under part, near head) is pretty
distinct and is very diagnostic of this
species. If you sees that pattern, then you
have a brown recluse. The large pedipalps
(bulbous things near the head) and jaws are clear
too. There are many good websites for photos.I
particularly like spiders
and brown recluse.
I hope this helps...and you should be sure
they're dead before you mess with them!!
