How often do you change a tarantulas cage?

A tarantula's cage should be cleaned and changed every 4 to 6 weeks, depending on the species and the level of waste accumulation. It's important to remove uneaten food, waste, and any mold to maintain a healthy environment. Additionally, a full substrate change may be necessary every few months to ensure proper humidity and cleanliness. Always handle the tarantula carefully during cleaning to minimize stress.
