Pill bugs, millipedes, sowbugs, roly polys, and centipedes. These are all
multi-legged non-insect type creatures that inhabit the same type of wet, highly
mulched areas around the home.
In the spring and summer, these creatures sometimes migrate by the thousands,
marching toward and into your house. No one knows for sure what causes these
migrations. The best guess is that it's a combination of temperature and
humidity. Millipedes and their kin like secluded damp areas where they can feed
on decaying plant material. But too much or too little moisture in their
environment can make them leave these areas in huge numbers.
Natural Millipede Control
- De-thatch lawns - Millipedes thrive in the dense upper thatch of grass.
- Mow lawn close - This allows the lawn to dry out.
- Remove debris - Millipedes live under boards, rocks, mulch, etc.
- Water the yard in the early morning - This lets the yard dry before night.
Chemical Millipede Control
Because millipedes are not insects the standard insecticides such as diazinon,
dursban, malathion, etc. have little effect on them. The best pesticide to use
Ficam W, but this is no longer available. A good substitute is Demon WP. It will give you excellent
control of millipedes and their kin. Spray areas where the millipedes are
thickest and also spray 3 feet completely around the house and 3 feet up on the
foundation of the house to prevent entry of the millipedes inside.
