This is excellent wheat bran for feeding mealworms. A certain YouTuber conducted a mealworm feeding experiment, showing the growth rate of mealworms based on their feed: Bran ≒ Goldfish food ≧ Quail feed > None Bran > Cat food > Carrot > Rice bran Bran > Rabbit feed > Guinea pig feed > Breadcrumbs Bran ≧ Bran + Wood shavings > Rabbit feed + Wood shavings > Wood shavings Bran > Whole wheat flour > Oatmeal > Wheat flour It's an overwhelmingly effective feed. It can also be used as bedding for hamsters and reptiles. If you don't want to keep multiple types of supplies at home, or if managing inventory is a hassle, why not switch to bran? ・Shipped via Yu-Yu Packet Post, with simple packaging. Pet Type...
