Why does my new house in south Killeen have mice?

Grading nearby land displaces field rodents, and new homes have small construction gaps. Sealing those gaps and trapping for a few weeks usually settles it.

Will the problem go away once construction is done?

Pressure usually drops once the surrounding land is built out and landscaped, but sealing the house is still worth doing.

Does my builder have to fix gaps?

Check your builder warranty. Some cover gaps around doors and utility penetrations in the first year.

South Killeen is where most of the city's new housing is going. Local reporting in 2025 described about 300 homes planned along Featherline Road with more to follow, the 1,370-acre Turnbo Ranch development with about 3,000 homes planned, and the 390-acre Preserve at Thousand Oaks with roughly 1,200 homes once complete. The city approved an $11.7 million bond to widen Featherline.

New houses, old residents

Every acre of pasture that gets graded held field mice, cotton rats and other small rodents. When the bulldozers come through, those animals move to the nearest cover, which is often the finished homes in the previous phase. Homeowners in brand-new houses in south Killeen are often surprised by mice in the first year. The house is not dirty; it just sits next to their former home.

New construction leaves its own gaps. Garage doors that have not been adjusted to the slab, weep holes in brick, gaps at the AC line set and unfinished landscaping all give rodents a way in. Builder warranties may cover some of those gaps; ask your builder before paying for repairs.

Utility districts and common areas

Turnbo Ranch is part of Bell County Municipal Utility District No. 2, and many new subdivisions have homeowners associations that manage common areas, drainage and detention ponds. Those open spaces hold rodents. If you see burrows in a common area next to your fence, tell the HOA or district in writing. The city also approved a $1.8 million design contract for the Featherline reconstruction, so expect road work here too.

What to ask for

Ask for an outside walk-around first: garage door seal, weep holes, utility entries and the roofline. Ask whether a monitoring plan makes sense while the next phase of construction is underway. Native field mice like deer mice can carry hantavirus, so clean up droppings in garages and storage the CDC way: ventilate, wear gloves, wet them with disinfectant and wipe them up. Don't sweep or vacuum them.
