How Long Does It Take for Spider Eggs to Hatch?

By Staff WriterLast Updated April 08, 2020

Spider eggs take one to four weeks to hatch depending on the species of spider. An exception are certain species that live in temperate climates; they lay eggs in late fall or early winter but the eggs remain inside the sac until hatching the following Spring.

Spiders lay their eggs inside silk sacs that contain hundreds or even thousands of eggs. Common garden spiders secure the egg sacs in their web, while the larger wolf spider carries its eggs and babies on its back. Spiders have a short life span and many common species die after laying eggs, leaving the sac vulnerable until the eggs hatch and disperse.
