Black Worm-Like Creature Infesting Basement Floors #353616

Asked August 16, 2016, 12:19 PM EDT

These creatures are in relative abundance on basement concrete floor. Creatures appear fairly uniform in physical appearance: black, ~1 inch length, 50 years; but, only in last couple of years have they been so noticeable. This year: very noticeable. Thank you, Jim Kennedy

Please reply with clear photos of the insect.
Attached file, "Bug.jpg," shows small collection of dead bugs. The coiled bug seem to be about "0.25" inches in diameter; maybe a bit smaller. We see these dead creatures scattered around the basement concrete floor. Don't seem to see any live ones at this time. Hope this helps. Jim Kennedy

This is a type of millipede. They are found in damp areas around foundations, basements, etc. Here is an Extension publication that has some management instructions: http://www.extension.umn.edu/garden/insects/find/sowbugs-millipedes-centipedes/

If you continue to have issues with millipedes in your home, you may want to contact a pest control company.
