If you have a jumping spider in your home, you should keep an eye on its abdomen. It may not be shrinking much because it is carrying around a large number of infertile eggs. However, you can still feed it by giving it one fly every two days to help it build its nest. Remember, though, not to feed them too much because you don’t know what kinds of parasites and diseases they may carry.
It is important to note that most spiders are not dangerous and only a few species have the potential to bite humans. These include the brown recluse and black widow. Because they have two mouth parts, many people make the mistake of thinking a jumping spider is going to bite them. This is not the case though, because jumping spiders have big eyes and fuzzy faces. They will not bite you unless you disturb them.
Jumping spiders eat almost anything that moves in their habitat, but they do prefer smaller prey. They generally go after insects that live within their habitat, such as tarnished plant bugs and Anthonomus grandis. They can go up to 30 days without feeding.
Another source of food for jumping spiders are waxworms. These are available in pet stores. While they aren’t the most preferred mealworms for a jumper, they are very nutritious and a great source of protein.
