Homes and pest entry points

The median year built for housing in Vermillion is 1978, and about 53% of its 4,702 housing units were built before 1980. Homes from this era often have settled foundations, aging weatherstripping and wood trim that can let pests in, and many have crawl spaces or basements worth checking for moisture. About 50% of housing units are in buildings with two or more units, where cockroaches and bed bugs can move between neighboring homes through shared walls and plumbing.
