DTE dropped insect frass from their offerings...organic replacement recommendations?

I was looking to purchase some black fly frass from DTE, but they dropped the skew.

Any organic replacement recommendations?

Thank you

don't know where they come from and if you can get them cheap enough. but Frass Fertiliser is an organic fertiliser made from mealworm frass—the nutrient-packed poop and exoskeleton remnants of mealworms. It's a sustainable, eco-friendly product that improves soil health, promotes robust plant growth, and naturally deters pests
