yes some mites arent an issue such as soil mites but there are a wide variety that are a nuisance to your setup as well as pets. i do agree that for older torts outside its not a common issue but hatchlings and indoor bioactive setups ive had some hitchhikers invest my setup.
from what i hear you can use diatomaceous earth and its good for killing insects. its 100% natural and you can feed it to your pests as well as eat it yourself lol (no joke you really can) but yea you sprinkle a light dusting around the pen on the soil and thats it. it should kill everything in...
I have a large enclosure I built for my 3 redfoot torts and I'd like to know how many worms would be enough for that size? I already have springtails in there as well. Are there anything else I can add that wont be a nuisance but be beneficial? Sorry glass is foggy from humidity lol
