I just got home from work and found an earwig in my Russian tortoise enclosure. I sucked it up with the vacuum right away! My tortoise has the Zilla Alfalfa Meal Litter and timothy hay in his tank. The hay is in a sealed plastic tub. I keep everything locked up, including windows, and I don't bring anything in from outside so I don't know how this happened. My tortoise looks just fine so I don't think I need to call a vet but should I be looking for more bugs? Should I spray the room where I keep his tank? Any thoughts? Thanks, everyone!
