Mouse Control

Mouse pressure in Hyattsville tracks the housing stock. The 1920s–1940s brick homes around Historic Hyattsville and the blocks near the Municipal Building on Gallatin Street often have stone or rubble foundations, mortar that has crumbled at the sill line, and old coal-chute or utility openings that were patched with wood rather than metal. Mid-century houses in University Hills and Castle Manor tend to leak mice at the garage door corners and the gaps behind kitchen cabinets where plumbing was run. Attached and semi-detached homes in West Hyattsville, Kirkwood, and along the Arts District corridor share walls, so a mouse population feeding in one unit travels a whole block through joist bays. Homes backing onto the Northwest Branch near Driskell Park and the Anacostia Tributary Trails get steady outdoor rodent pressure from the wooded floodplain edge, and that pressure turns indoors during the first cold snaps of October and November.

Mouse control is the right service when the evidence is small: rice-grain droppings, quarter-inch gnaw marks, scratching inside a wall or above a drop ceiling at night, and shredded insulation or dog food in a cabinet corner. If the droppings are the size of an olive pit, there are burrow holes in the yard, or something heavy is moving in a crawlspace, that is rat activity and calls for exterior burrow work and heavier exclusion instead. The trade-off worth knowing: trapping alone removes the mice you have, while sealing decides whether they come back. A trap-only visit is cheaper up front and sometimes appropriate for a single mouse that wandered in through an open basement door, but recurring activity in an older Hyattsville basement almost always means an open pathway that needs metal, mortar, or foam-and-mesh repair.

We favor traps and physical exclusion over scattering bait indoors. Bait placed loose in a kitchen or basement creates a real risk of a mouse dying inside a wall cavity, and in Prince George's County rentals that turns one complaint into two. Where rodenticide is used, it belongs in tamper-resistant stations in controlled exterior locations, and Maryland requires pesticide applicators to be licensed through the Maryland Department of Agriculture — ask any company, including this one, to state its credentials before work starts.

For landlords and property managers in Lewisdale, Queens Chapel Manor, Hyattsville Hills, and the Riverdale Heights side of the line, documentation matters as much as the trapping. We note the unit, the date, the entry points found, and the sealing performed, so you have a record if a tenant raises a habitability issue or a county inspector asks what was done. In multi-unit buildings, treating a single unit rarely holds; adjacent units, the shared basement, and the trash enclosure need to be included or the mice simply shift one door over. Pests out. Entry points sealed.
