Some baby spiders will even eat their siblings if they are hungry enough.

As most parents know, baby spiders eat mostly insects. But what kind of insects do they like to eat? And how do they catch them?

Well, different species of baby spiders prefer different kinds of insects. For example, some common prey for baby spiders include flies, ants, beetles, and caterpillars. They also like to eat moths and other small flying insects.

How Do You Feed Baby Spiders?

In the wild, baby spiders will eat just about anything they can catch. This includes other insects, small animals and even other spiders. However, when it comes to feeding baby spiders in captivity, you’ll need to be a bit more creative.

One way to feed baby spiders is to offer them live prey. This can be done by placing a small cage with the spider inside next to an enclosure with live insects. The baby spider will then be able to catch the prey as it wanders into its cage.

Another option is to offer the baby spider pre-killed prey. This can be done by placing the dead insect on a piece of paper or cloth and offering it to the spider on a tweezer or similar tool. The baby spider will then wrap up the prey in its webbing and enjoy its meal.

Finally, you can also offer baby spiders commercially available insectivore diet pellets. These are designed specifically for young arachnids and provide all the nutrients they need to grow and thrive. Simply place a few pellets in their enclosure and let them feast away!
