Not really. I keep them out of dog poop, stinging nettle, ant hills and spider webs lol. Other than that anything that could hop on them and cause issues you can't safeguard agaisnt. I'm in the yard enough that the pests would just come in with me even if I didn't bring the snakes outside.
Plus our climate here doesn't support many bugs that would cause detriment to the snakes. It's still dropping down to 40° at night right now, and 80-85° in the daytime.
