Millipede Infestations in Florida Homes: What You Need to Know
After heavy South Florida rain, those long, dark crawlers on your driveway are millipedes. They don’t bite like wasps or damage wood like termites, but millipede infestations in Florida homes can feel overwhelming when many crawl indoors.
For homeowners in humid climates such as West Palm Beach, Fort Lauderdale, and Miami, millipedes are more than just an outdoor nuisance. After heavy rain, they slip in through cracks around doors and windows, gaps under thresholds, and openings to basements or crawl spaces. Know why they invade and how to stop them to keep your home pest-free.
This guide covers what attracts millipedes, how to tell them from centipedes, and the best steps for millipede control in Florida, including the yellow-banded millipede.
Key Takeaways:
- Heavy rain drives millipedes inside. Saturated soil sends them indoors seeking dry spots, sometimes in large numbers.
- Mulch, leaf litter, and soggy beds boost millipedes. Dense landscaping and poor drainage make repeat problems more likely.
- Millipedes aren’t dangerous, but their defensive fluid can stain and may irritate sensitive skin.
- Prevention works best: reduce moisture, seal entry points, and, if needed, use professional pest control to stop infestations before they start.
Understanding Millipedes in Florida Homes
Millipedes are arthropods with long, round bodies made of many segments, and most segments have two pairs of legs. Despite the name, they don’t have a thousand legs. They move slowly. Centipedes move fast and can bite.
Millipedes eat mulch, decaying plant matter, and leaf litter. Outdoors, they help recycle nutrients.
In Florida, homeowners are most often encountered by the yellow-banded millipede. They are dark brown to black with a clear yellow stripe down the body. If threatened, they curl into a tight spiral and may release a mild fluid. This secretion deters predators outdoors but can leave stains or mild irritation when handled indoors.
Indoor millipedes are rarely harmful, but seeing many at once is frustrating. Their presence usually signals damp conditions outside. Addressing these conditions is the first step in controlling millipedes in Florida homes.
Why Millipede Infestations Happen in Florida
Millipede infestations are common where humidity and rain remain high. In South Florida, humid weather and lush landscaping create ideal conditions. Millipedes thrive under mulch, leaf litter, and even in clogged gutters where it stays damp.
After heavy rain, the soaked soil pushes millipedes up to the surface. They then crawl to drier shelter and slip inside through gaps in doors, windows, siding, basements, and crawl spaces. Indoors, most die quickly in dry air, but seeing many at once is still alarming.
Thick landscaping and frequent mulching raise activity. Decaying plants, grass clippings, and other food sources keep millipede numbers high. While millipedes play an essential role in the ecosystem by breaking down organic matter, they turn into a nuisance when their search for better conditions leads them indoors.
Understanding these environmental factors is crucial for both preventing infestations and maintaining a pest-free home in Florida.
Millipede Problems Inside Florida Homes
When millipedes show up indoors, it’s usually after heavy rain. They don’t intend to stay, but even a handful of them crawling across floors or walls can feel unsettling. Piles of curled-up millipedes near doors, baseboards, or garages are a common complaint from Florida homeowners.
Although they don’t pose health risks, their defensive secretion may stain surfaces and irritate sensitive skin if touched. The main “problem” is the mess and discomfort of seeing so many at once, especially when dozens gather around entry points after storms.
Millipede Control and Prevention in Florida
Millipedes can’t live or breed indoors. Sweep or vacuum them up and discard them outside instead of waiting for them to die. Avoid handling them directly.
To keep them from coming back, focus on preventative measures outside the home:
- Dry out problem areas: Fix leaks, improve airflow, and run dehumidifiers where needed.
- Improve drainage: Clear gutters, extend downspouts, and grade soil away from the foundation.
- Tidy the yard: Remove leaf litter, bag clippings, and keep mulch 12–18 inches from exterior walls.
- Seal the house: Add door sweeps, caulk window frames, and patch cracks in slabs or siding.
If millipedes keep appearing in large numbers, a pest professional can apply perimeter treatments and offer moisture-control solutions for long-term results.

FAQs
Are millipedes dangerous to people or pets?
No, millipedes are not harmful. They do not bite or sting, but their secretion may cause mild skin irritation or an allergic reaction in sensitive individuals.
Why do millipedes suddenly appear in large numbers?
Large numbers of millipedes usually emerge after heavy rain or when the soil is too wet. They come indoors seeking dry shelter, often entering through small cracks or crawl spaces.
How can I keep millipedes from entering my home?
The best approach is prevention. Keep mulch and leaf litter away from your foundation, seal cracks and crevices, and use a dehumidifier in moist areas like basements or crawl spaces. If the millipede problem continues, call a professional pest control company for targeted treatments.
