What do mites look like? I have found today that i have some white things (really really tiny) moving around in my C. Meridionalis enclosure. I have also before found them in a scorpion enclosure and also my leopard geckos once. Thing is, when i see pictures of mites, they look kinda fat and round, and these things dont. Not sure if theyre coming from my substrate, but its a mix of bed a beast and potting compost (the organic, ingredient free stuff). I have been told that these come when there is not enough ventilation and it is too humid, which my spider isnt, and my geckos definately werent. Thing is, i cant find any other substrate for terrestrial species, so what can i do? Will they harm my spider??? Like i say theyre tiny, les than a mm in length...
