Handling a pet tarantula should be done with caution and care to ensure both your safety and the tarantula's well-being. It's generally recommended to avoid handling tarantulas unless necessary, as they can easily get stressed or injured. If handling is necessary, make sure to move slowly, use a soft brush or a gentle touch to encourage the tarantula to walk onto your hand, and support its body fully to prevent any falls. Always wash your hands before and after handling to avoid any potential harm to the tarantula due to chemicals or oils on your skin. Remember to always research the specific care requirements for your tarantula species to ensure you are meeting its needs properly.
