Why Millipedes Are Common in La Jolla
Millipedes are moisture-dependent decomposers that live in mulch, leaf litter, compost, and other decaying organic material. After heavy rain or irrigation, millipede populations sometimes migrate in large numbers toward structures, entering through foundation cracks, door sweeps, and garage thresholds.
While millipedes don't bite, sting, or cause structural damage, mass migrations can be alarming and messy. They curl up and die indoors due to lack of moisture, leaving behind staining and an unpleasant odor.
Our treatment targets millipede breeding zones in the landscape and creates a barrier at the structure to stop migrations before they reach the interior.
How We Handle Millipedes
- Perimeter barrier at foundation and entry points
- Granular treatments in mulch beds and ground cover
- Treat under pavers, retaining walls, and landscape borders
- Recommend mulch depth and moisture management adjustments
- Ongoing treatments to prevent seasonal mass migrations
The Simple Pest Difference
TriShield™ Three-Zone Protection
We don't just spray your foundation and call it done. Our three-zone system creates overlapping barriers that stop pests before they reach your door.
Property edge barrier to stop pests at the perimeter
Turf, planter, and hardscape treatments to reduce pressure
Entry-point lockdown around the structure itself
Signs of Millipedes
- Clusters of millipedes on exterior walls or near doors after rain
- Dead curled millipedes inside the home, especially on hard floors
- Millipedes under mulch, rocks, or compost in large numbers
- Dark staining on surfaces where millipedes have been crushed

Mass millipede migrations happen after heavy rain saturates their habitat. They move toward drier ground — often your home's foundation. Perimeter barriers and landscape treatments prevent this.
No. Millipedes don't bite or sting. Some species secrete a mild irritant if handled, but they're primarily a nuisance. The real issue is the volume during migrations.
Heavy rain saturates the soil where millipedes live, forcing them to the surface and toward drier ground — often your foundation. Perimeter protection stops these mass migrations before they reach the interior.
No. Millipedes don't bite or sting. Some species secrete a mild irritant if handled, but they're completely harmless. The issue is the volume during migrations.
Reduce mulch depth near the foundation, fix drainage issues, and maintain a clear gap between soil and your structure. Our perimeter barrier provides ongoing protection against migrations.
No. Millipedes don't cause structural damage. They die quickly indoors due to lack of moisture, but can leave staining and an unpleasant odor when crushed.
