Many many years ago we lived in Southern Arizona, had a small garden. DH decided we needed to get some of those Tarantulas to eat the bugs in the garden. So out we went to gather up some of those big hairy spiders, got about a dozen after all they were all over the roads. Turned them loose in the garden thinking it should be spider heaven. Next day not one remained except the one squashed in the driveway. Ingrates didn't appreciate what we gave them.When I was much younger, my sister told me spiders bring good luck and I actually believed her and was never really frightened by them, but Tarantulas used to sort of creep me out..... until I took a really close-up look at a dead one and saw how beautiful it was...
A few months later I was watching a TV show on the various animals in Az. Found out that everyone of the tarantulas we had picked up was a male looking for love. Turns out the females live in an underground nest and rarely ever go more than a foot from the den . The fellows have to wander a lot to find that special someone.
