There are lots of tiny gnats in Master Oogway's indoor enclosure. I've tried mixing up the coconut coir, hoping they're just fly away but they didn't. Any suggestions on how to get rid of these little pests? What attracts them?
They are probably fungus flies. They lay eggs in your damp substrate, and will also live in the potting soil of plants. I just tolerate them here because they don't hurt anything, but if you want to get rid of them you could try letting your substrate get really dry, or add some pill bugs to your enclosure and let them clean up the problem.
