Spiders can live without food for roughly four to eight weeks and for three weeks without water; in fact, spiders can store food and water within them that they may utilize during times of fasting or when they do not have anything for them. If their food stockpile is depleted, they still have a chance of going several weeks without being able to find anything to eat.
When you finally get around to feeding your spider after a few weeks have passed, you should provide them with an insect that is alive and of a smaller size than is typical for them. Your spider has a strong preference for eating live insects because they are drawn to the activity that the insects give off. In addition, the spiders favor preying on insects whose bodies are significantly smaller than their abdomens. If you offer them enormous insects, they will gorge themselves to the point of being unwell.
