The spider does not need handling
Tarantulas do not need handling for socialisation or enrichment. A secure enclosure, suitable retreat, water, feeding and normal environmental conditions meet their husbandry needs.
Fall risk
Heavy terrestrial tarantulas are vulnerable to falls because the abdomen is soft and can rupture. A drop from hand or arm height can be far more dangerous than any normal movement inside a well-proportioned enclosure.
Urticating hairs
Many New World species can release urticating hairs. Handling puts skin, eyes and airways closer to those hairs and increases exposure for no husbandry benefit.
Old World species
Fast Old World species add greater speed and bite risk. Keep them hands-off and design feeding, watering and rehousing so the spider can be managed with tools and a catch cup.
Moving a tarantula
When a spider must be moved, guide it into a catch cup or directly between secure containers. Work in a closed room, remove pets and distractions, and know where the spider can retreat before opening the enclosure.
Routine maintenance
Keep long tools and a catch cup beside the collection. Position water dishes and service openings so feeding and cleaning can be done without reaching across the spider or forcing it out of a retreat.
When to seek help
For serious injury, uncontrolled haemolymph loss, severe failed moults or a spider that cannot stand or move normally, contact an exotics or invertebrate-experienced veterinary professional where available. Significant eye exposure to urticating hairs or systemic symptoms after a bite need appropriate human medical care.
