Centipedes and millipedes are most often seen in yards and gardens, sometimes finding their way into houses. They are not insects, but they belong to the same group in the animal kingdom as insects and crustaceans.
While centipedes have 1 pair of legs per body segment, millipedes have 2 or 4 pairs of legs per body segment. Centipedes move more quickly than millipedes and are more prone to biting.
