Q: In all this dampness, we have had a lot of millipedes. They crawl up the side of the house and across the drive. Can they harm anything?
A: They don’t bother anything except your nerves. It’s creepy to step on one or a dozen and hear the crunching sound. After rains like we’ve had it’s not uncommon to sweep up hundreds, if not thousands, from sidewalks and garage openings. You can control them using landscape insecticide spray or granules in a sixteen-inch wide band around your house foundation or in places where you see them collecting.
