Types of Centipedes in California

Tiger Centipede

• The Scolopendra polymorpha, or tiger centipede, reaches 15 cm in length or more. It can exhibit a number of colors including blue, green, brown, black, yellow and orange on its exoskeleton. They are not particularly aggressive and can be kept in captivity, but they will occasionally bite. Though not deadly to humans, the bite can be very painful. They feed primarily on insects and prefer an arid environment.

House Centipede

• The house centipede ranges throughout California and is very common. Unlike other centipedes, it may live its entire life in a building, as opposed to other centipedes which will prefer to live outside. House centipedes favor damp, dark environments like cellars, crawlspaces and closets. They eat other pests but lay their eggs in homes sometimes. They have very long legs and will bite but are not particularly aggressive.

Soil Centipede

• Soil centipedes are long, thin centipedes with flattened segments and 27 or more leg pairs. Like other centipedes, they are carnivorous, but do not have the ability to bite humans or inject venom. Instead, they feed mostly on insect larvae. They burrow in the soil, breaking it up and aerating it. They tend to lay their eggs in rotted wood or in the soil and lay between 15 and 60 at a time. There are over 1,200 varieties.

Stone Centipede

• The stone centipede, or lithobimorpha, is among the oldest species on the planet. They range across the world in various forms. They have 15 pair of legs and live under rocks and logs.
