I recently sold my A. Geniculata. I had her in a 10 gallon tank with about 6 inches or so of substrate to keep her close to the top. Anyway she was only in that tank about two months. My question is, I use the same substrate for my boa constrictor and I wanted to reuse the substrate from the tarantula cage for the snake cage but I have some concerns whether leftover urticating hairs might cause a problem with the snake. The stuff is kind of expensive on my budget and I figured at the very least I could just scoop out the top inch or so and thought that would be adequate enough to eliminate most if not all of the hairs that might be residing there. I don't want to take any unnecessary risks to the snake's health if there are any. Any thioughts?
