Next get some horseshit, cowshit, rabbit shit, etc, as long it is herbivores, and fill the whole thing up. You can also add rotten vegetables and vegetable off cuts.
NO animal products except egg shells.
Then get some earthworms, check the fishing shops out since they sell live bait.
Give these guys a new home:
