Everything You Need to Know About Millipedes

Have you ever descended to your basement only to find a full-scale millipede invasion? Have you frowned at these small, worm-like critters and their spidery-legged cousin, the centipede, without understanding where they come from? Are you bewildered why their entire clan chose to visit you? Here's how to identify millipedes and prevent them from taking over your home.

What do Millipedes Look Like?

  • Millipedes are small arthropods with many legs and short antennae.
  • Contrary, to popular misconception, however, they do not have 1,000 legs. 
  • They’re different from their centipede cousins in that they walk slower, scavenge for food instead of hunting it, and don’t bite.
  • Typically 1 to 1.5 inches long
  • They curl into a tight coil when they feel threatened and remain motionless until the danger has passed.

When Are Millipedes Active?

Nighttime is their active time. When they’re not out scavenging for a delicious decaying organic dinner, they’re most likely to be found hiding under objects in a dark, damp environment.

Can Millipedes Bite?

Actually, these little guys are pretty harmless. They don’t bite, sting, chew clothes or furniture, or ruin food. Their preferred dish is dead leaves or other decaying organic matter.

Where do Millipedes Live?

If they’re in your home, it’s probably because their outside environment is too hot or wet. Although millipedes do live in damp areas, excessive rainfall or over-watering your garden beds will drive them to seek dryer conditions–namely, your basement. And to escape the summer’s heat, nothing says “chill and relax” like those dark spots behind your basement boxes. They’re accessing your home through doors, ground-level windows, and foundational cracks.

How Can I Prevent a Millipede Infestation?

If you have a minor to moderate millipede invasion, basic preventive care may be enough to solve your problem.

  • Sweep existing millipedes back outside.
  • Repair cracks to your foundation.
  • Check your doors and windows to make sure the sealer doesn't need replacing.

You can also keep piles of dead leaves and other organic matter away from your home. If you have shrubs touching your house, make sure they aren't planted too thickly. Too many plants clustered in one area will prevent the soil from drying properly, and that could be the stepping stone that draws the millipedes away from the outdoors into your home.
