Friendly Neighborhood Insect & Mouse Killer
Wiki says:
"Tarantulas mainly eat insects and other arthropods, using ambush as their primary method of prey capture. The biggest tarantulas can kill animals as large as lizards, mice, and birds. Tarantulas are found in tropical and desert regions around the world. Most tarantulas are harmless to humans..."
That last sentence is very nice to know. Especially when I walked into the guest bedroom one morning and found this guy just sitting there in the middle of the floor. Not sure if he was sick or just REALLY slow, but he didn't even react to me at all when I gently escorted him outside. Figured I should do that just in case some future guest did not appreciate his help with insects & mice.
