nbsp What substrates work for tarantula housings?
  I personally use peat moss for all my habitats. It has proven to be easiest to maintain from a cleanup standpoint, easy to form around a burrow, the tarantulas seem to universally approve of it, and it’s also inexpensive. You can also do a 50/50 mix of potting soil and peat moss or a 50/50 of potting soil and Vermiculite. Vermiculite by itself has never worked well, the tarantulas tend to climb up the sides of their enclosure to stay off it. I’ve also seen it stick to their feet which of course they don’t like. It’s rather funny watching a tarantula try to shake vermiculite off of 4 feet at once while balancing on the other 4. Whatever product you buy as a substrate make sure to read the label, you don’t want any pesticide or herbicide added.
