I was a florist for many years and the darndest things travelled in. Had green tree frogs, some kind of crazy gecko-lizard thing and a recluse spider that chose to bite my ankle. Of course i was smart and when I felt that I had sprained my ankle went to the doctor. Antihisimine and Anti-biotics put me straight in a week.
As far as snakes, bats, spiders go, I can say didn't care much for bats for the longest time or spiders after being bitten, but we humans need to have respect for our neighbors. Afterall in most parts of the world, they were there first. I do not mind snakes, and have encountered my ribbon snakes here and once a copperhead- I'm getting better, I don't scream now!
