Feeder insects are the most likely part of a reptile move to go wrong — not by dying, but by escaping. A tub of crickets loose in a car or a new house is a problem that outlives the journey, so pack feeders as livestock with their own needs, in containers secured for a tip-over you hope never happens.
Tub Them Properly, Species by Species
Keep each species in its own sturdy tub with a lid that clips or tapes shut, and add tape over the seal for travel even if the lid feels secure at home. Crickets, roaches, and locusts need pieces of egg crate or cardboard stacked inside: it multiplies their surface area, stops them crushing and overheating in a pile, and dramatically cuts deaths on a warm journey. Mealworms and other larvae travel best in their usual substrate or a layer of bran or oats, which is both bedding and food. Ventilation matters — tubs need their usual air holes or mesh — but check hole size against the smallest nymphs in the tub, because a ventilation hole a baby roach fits through turns the car into the colony.
Pack a small amount of dry gut-load food in each tub and a moisture source that cannot spill: a chunk of carrot, potato, or squash rather than open water, which drowns insects and sloshes. Feeders that arrive fed and hydrated are worth feeding to your reptiles; feeders that arrive starved and dehydrated are nutritionally poor and die off faster at the other end.
Temperature: Cabin, Shaded, and Away From Heat
Travel tubs go in the cabin at the same moderate temperature as you and the reptiles — roughly comfortable room temperature — upright, wedged so they cannot tip, and shaded from sun through the windows. Two heat mistakes kill feeders fast. The first is placing a tub against or on the heat pack you packed for a reptile: insects overheat in a small sealed volume far quicker than the reptile does, and a tub that feels warm to you can already be lethal inside. Keep clear physical distance between feeder tubs and any heat source. The second is the boot on a hot or freezing day, where temperatures swing well beyond what the cabin reaches. In cold weather, an insulated box holding the tubs together smooths out the dips without adding heat.
Keep feeders physically separate from the reptile containers themselves. A stressed reptile travelling beside a tub of visible, moving prey is being teased for the whole journey, and if a feeder tub does fail, you want the escape contained in one part of the car.
At the Destination, Feed in Order
Label every tub before you leave: species, approximate count, and the date packed. At the destination, set the tubs up somewhere cool, dark, and out of living areas before you unbox anything else, check each lid before opening, and feed from the tubs in the order you packed them so counts stay honest and older stock is used first. Recount after the journey — some loss is normal, and knowing your real numbers stops you discovering an empty colony the night a hungry lizard needs feeding.
Note the counts, which species went with which reptile, and the feeding days in KinsLe's Care Pass, so whoever feeds at the destination — you, a partner, or a sitter settling the animals in — works from the same unbroken schedule the reptiles had before the move.
