Yen has shared his feeder insect dusting powder formula with us so we can make it available to you! The mixture is 66% finely ground BEE POLLEN and 34% finely ground DRY HONEY POWDER. All you do is pour some in a bag, shake the feeder insects in the bag, and feed them to your mantids. These ingredients, if not ground to a fine powder will not stick to your feeders, and not benefit the Mantids. We have done the mixing and the grinding, you just dust the feeders, and give to your mantids for proven nutrition.
