I keep both my ball pythons in 40 gallon terrariums. they're both very clean and healthy snakes. I'm not concerned about their health at all, but I am curious about something. sometimes when I go in their cage to spray some water or clean up, I'll see little tiny flys flying by the heat and sometimes they'll get in their water bowls. should I be concerned about this? is it normal? are they just like getting in through the screen because they like the humidity and heat? I highly doubt either of them has mites, because they don't show any signs, like soaking or having fleas on them when I take them out. this is probably a really dumb question, but I just want to make sure. I'm pretty sure it's just fleas or something
