Centipedes and Millipedes

In the warmer months of June and July, you might unexpectedly cross paths with a centipede or millipede, as both creatures prefer moist environments leading them to your bathroom, basement, and any other damp spot in your home. Although you’ll find these arthropods in the same areas of your home or business with similar appearances, there are differences between the two. 

How to Identify Centipedes and Millipedes

Centipedes and millipedes can vary in color but are typically brown or black with a bit of red and occasional markings. Similarly, they have antennae and an abundant amount of legs—embodying the classic image of a horror-inducing creepy-crawler. Both vary in size and appear long and wormlike, though centipedes are flat while millipedes are cylindrical.

Differences Between Centipedes vs. Millipedes 

The key visual difference between a centipede and a millipede is its legs. While they both have segmented bodies, centipedes have one pair of legs for each body segment, but millipedes have two pairs of legs for each segment. 

The two arthropods have behavioral differences as well. Centipedes are carnivores that prey on other pests, but millipedes are herbivores and detritivores that eat dead or decaying organic matter. When they feel threatened, centipedes typically run away quickly but can also bite if handled by humans. On the other hand, millipedes coil up while secreting a stinky scent.
