California Trapdoor Spider Facts; Size & Bites

They grow up to about 2 inches long and have a round and thick body that is a shiny black color with a dark brown abdomen. They sometimes will have a brownish or reddish color body as well. These spiders are often kept as exotic pets. However, these species of spiders should only be kept by experienced spider handlers. They are an extremely aggressive spider with a painful bite.

If you ever encounter one of these spiders in or outside your home, be careful not to provoke them or they will attack without warning; and they move very fast. These spiders have a few enemies such as scorpions and wasps.

Burrows of the California Trapdoor Spiders

The California trapdoor spider is a species of spider that lives in burrows in the ground and creates a trap door out of vegetation, soil, and webbing. They prefer to live in warmer climates and near rivers where they will catch and eat small fish and other insects. The trapdoor spider will also eat baby birds, snakes, frogs, and small rodents. They will occasionally dig their burrows on lawns and gardens due to the soft soil and plentiful amounts of garden pests to feed on. Males will search for female trapdoor spiders and mate inside the female burrow. Most will escape the burrow after mating but some are unlucky enough to be eaten by the female. Even so, they will continue to mate with other females until the one lucky female convinces him to stay around for dinner. The female trapdoor spider will lay her eggs inside her burrow protecting them until they hatch. They will remain with their mother for several months before emerging to find their own way. A trapdoor spider can live anywhere from 5 to 20 years.
