House centipedes have long, flattened and segmented bodies with one pair of legs per segment attached to the sides of their body. They grow up to 1 plus inches in length, have 15 pairs of long, thin legs with dark and white bands, are brown to grayish-yellow, have three longitudinal dark stripes on top, well-developed eyes, and poison jaws connected to poison glands used to kill insects.
House centipedes lay an average of 60 eggs in the spring or early summer. The larva hatch with four pairs of legs and will complete 5 instars increasing the number of leg pairs they have each time 5,7,9,11, and 13 pair. They will complete four instars after the larva stage before becoming adults.
The last pair of legs serve to wrap around their prey.
Inflammation and pain can last for a few hours.
Often found around the foundation of houses and other buildings, usually through thresholds or gaps in the foundation.
