Centipedes

Asked June 17, 2019, 1:35 PM EDT

I've lived in Charles County since the early sixties and this is the first year that I've seen these little dark centipedes inside and outside my house. I've spoken with family and friends and they're having the same issue. They're everywhere! They especially come out at night. What are they and is this something I should be concerned about?

Because you say they are small and dark, we suspect that you're seeing millipedes. Take a look at this page (the photo is much enlarged): https://extension.umd.edu/hgic/topics/millipedes
It's not unusual to have a little population boom of a particular insect, depending upon favorable weather to them, or unfavorable weather for their enemies.

Millipedes like it damp and feed on decaying vegetation, which there is a lot of when we have lots of lush growth and moisture, which we have had for the past two years (twice the normal rainfall). Their populations will go down when the weather changes. This is temporary.

Your homes may also be shadier as the years go by, thus creating a more moist habitat, too. Read our webpage above for tips.
