Food-grade calcium carbonate powder dusted on feed or mixed into substrate. Essential for gut-loading feeder insects, especially crickets destined for reptile feeding. Also helps buffer acidic substrates in BSFL bins.
$1-$3 per pound
Growing Supplement
Food-grade diatomaceous earth used as a natural pest control around (not inside) insect rearing bins. Kills mites and grain beetles that invade colonies. Sprinkle it around bin legs and shelving, but keep it out of the bins since it can harm your stock too.
$1-$4 per pound
Growing Supplement
Probiotic blends formulated for insect gut health. Added to feed or water to improve digestion, reduce mortality, and speed growth. Still an emerging area, but some farms report 10-15% better feed conversion ratios after adding probiotics.
$15-$40 per unit
Growing Supplement
Powdered vitamin and mineral premix designed for livestock feed, repurposed for insect farming. Contains vitamins A, D, E, and trace minerals. Mix at 0.5-1% into your base feed for more complete nutrition, especially when gut-loading feeders.
