Housing: space, air and climbing room
Crowding and stale air kill more feeder insects than hunger does. House each species in its own smooth-sided tub or ventilated bin, with a fine mesh or well-drilled lid — crickets especially produce moisture and ammonia that build up fast in a sealed box. Stack pieces of egg crate or cardboard vertically inside so the insects can spread out and get off the floor of the tub; a colony forced to live piled on itself overheats, stresses and starts dying. Smooth walls and a snug lid matter too: a loose top turns a cricket tub into a household escape incident.
Food and water inside the tub
A stored feeder is only worth what it eats, so keep the colony fed rather than merely alive. Offer fresh greens, squash and carrot continuously, replacing them before they wilt or mould, and add water gel crystals or a damp sponge for drinking — an open water dish drowns feeders within hours. Room-temperature produce doubles as the start of your gut-loading, so a well-kept colony is already halfway prepared for feeding day. Skip citrus and anything sprayed, and wash produce as you would for the reptile itself.
Temperature and species differences
Each feeder has its own climate. Dubia roaches stay sluggish and breed poorly when cool — they do best genuinely warm, while crickets are content at ordinary room temperature as long as the ventilation keeps their tub dry. Mealworms and superworms rest happily in a substrate of bran they can burrow into and eat. Whatever the species, keep tubs out of direct sun and away from radiators; a tub that overheats on a windowsill can wipe out in an afternoon.
Hygiene keeps colonies alive
Spend two minutes a day on the tubs. Pick out dead insects promptly — a handful of corpses rotting in the substrate fouls the air and food for everything else and is the usual start of a total die-off. Sweep out droppings and shed skins weekly, replace damp cardboard, and wash tubs between batches with hot soapy water, rinsed and dried thoroughly. Store the tubs somewhere quiet, dark and escape-proof, off the floor if the house has free-roaming cats. If a colony suddenly crashes with a sour smell despite clean conditions, discard it and start fresh rather than feeding survivors to your reptile.
Feeder care is one of those chores that quietly gets forgotten on busy weeks. KinsLe's Care Teams lets you schedule the daily checks, weekly cleans and feeding-day duties as timestamped tasks, so your reptile's food supply stays alive and nutritious whoever is on duty.
