Scorpions, tarantulas, and other arachnids are increasingly popular in the exotic pet trade, with welfare standards that are poorly developed compared to vertebrate companion animals.
Arachnid welfare in the pet trade suffers from the same fundamental problem as reptiles: these animals hide illness and distress effectively, and their needs are poorly understood. Wild-caught specimens experience capture stress, dehydration during transport, and exposure to temperatures outside their tolerance range. Captive husbandry failures — incorrect humidity, temperature, substrate, and feeding — cause slow-developing welfare problems that owners often misinterpret as normal behavior. Choosing captive-bred arachnids eliminates the welfare costs of collection while supporting breeders who often have better species knowledge than general pet stores.
