Spiders are highly adaptable creatures with impressive survival abilities, including enduring long periods without food. The duration a spider can survive without eating depends on its species, size, age, and environment. On average, most spiders can go without food for several weeks to a few months. However, some larger species, like tarantulas, can survive for over a year without eating if necessary. https://safepestsol.com/how-long-can-spiders-go-without-eating/
