Millipede Identification in South Florida
Millipedes are common outdoor nuisance pests found throughout South Florida landscapes, gardens, mulch beds, lawns, and moisture-prone areas. These slow-moving arthropods play an important role in breaking down organic matter, but large populations may become a nuisance when they migrate onto patios, into garages, or inside homes after periods of heavy rain. Millipedes are often confused with centipedes, although they move much slower and do not actively hunt other pests.
What Are Millipedes?
Millipedes are decomposers that feed primarily on decaying organic material such as leaves, mulch, and plant debris.
Unlike centipedes, millipedes have two pairs of legs per body segment and move slowly when disturbed.
How to Identify Millipedes
Common identifying characteristics include:
- Long cylindrical body
- Numerous legs
- Two pairs of legs per body segment
- Slow movement
- Brown, black, or reddish coloration
- Rounded body shape
- Curl into a spiral when disturbed
Millipedes are often seen after periods of rain or excessive moisture.
