Millipedes vs. Centipedes: How to Tell the Difference
As fellow many-legged creepy-crawlies, centipedes and millipedes are frequently confused with each other. There are a few things you can use to tell them apart, though:
- Number of legs. Centipedes have fewer legs than millipedes, and they tend to be longer. Millipedes have two pairs of legs per body segment; centipedes only have one.
- Body shape. Millipedes have rounded bodies and their legs are shorter, fitting underneath their bodies. Centipedes have flattened bodies with legs that stick out to the side.
- Movement speed. Millipedes move much more slowly than centipedes. They’re in no hurry.
- Diet. Millipedes are detritivores, which means they eat decaying plants and animals. Centipedes are omnivorous.
Signs of a Millipede Infestation
Millipedes commonly shelter under boxes or other storage material. You may find them after moving packaging material, especially in dark or quiet parts of your home or business. Millipedes require moisture to survive and will dry out and become “desiccated” if they don’t get enough. Desiccated millipede bodies may flake or fall apart, leaving behind crusty remains
Millipedes may secrete a foul-smelling liquid when threatened or crushed. This liquid may stain nearby fabrics such as carpeting. These stains will be small, vaguely circular, and yellow or brown.
Millipede Control and Prevention
Check for millipedes beneath storage materials in basements, crawl spaces, warehouses, and attics. Vacuum up any millipedes you encounter and dispose of the bag when finished. After removing millipedes, clear clutter to deprive millipedes of shelter. Manage waste diligently to control millipede’s food sources.
If millipedes live in your building for several weeks or more, then your building is probably too humid. Look for and fix causes of excess humidity. Patch up gaps, repair plumbing leaks, and make sure your ventilation and drainage work properly. Consider investing in dehumidifiers if the problem persists.
