They crawl in through a double door frame to my basement by the hundreds daily. The door is low lying so the area is nearly always moist.
Millipedes are usually going to be present when there is a lot of moisture in the area. If you have a lot of mulch near your house you may want to consider raking it back at least six inches away from the house. Also trimming bushes so that you can see the soil beneath them and so they do not touch the house will help reduce soil moisture and stop the insects from gaining access to the house via the bushes. We recommend using Cyper WP around the outside perimeter of the home (especially under and around eaves, decks, patios, and window shutters), and inside along baseboards, in cracks and crevices, and other potential millipede harborages. You should also use Delta Dust on and around the door frame as it will keep working even if it is wet. We have written an article with other tips that may help you with millipede control : Get Rid of Millipedes
