The Rat Most Greensboro Homes Actually Have
When a Guilford County homeowner reports rats, the animal is usually a Norway rat. It is the heavy-bodied brown rat that burrows rather than climbs, and it behaves very differently from the roof rats that dominate warmer coastal and desert cities. Understanding that difference is what separates a treatment that works from one that simply relocates the problem.
Burrowing rats are the single most common call Rodent Control Greensboro takes across Guilford County, and the response is the same every time: find the burrows, work the runways, close the foundation.
Norway rats travel at or below grade. They follow foundation walls, slip through utility penetrations, and exploit the vented crawl spaces that sit under a large share of Greensboro's brick ranch and mid-century housing stock. An attic-first inspection misses them entirely.
Where They Get In
On older properties near downtown, the weak points are usually mortar joints that have eroded, crawl space vents with rusted or missing screens, and the gap where a sewer lateral or water line passes through the foundation. On newer slab construction the entry is more often a garage door corner seal, a dryer vent flap that no longer closes, or an expansion joint that has opened up.
A rat needs an opening roughly the size of a golf ball. Once inside a crawl space it has insulation to nest in, ductwork to travel along, and direct access to wall voids and the subfloor.
Signs Worth Acting On
- Burrow openings two to four inches wide along a foundation, often part-hidden by shrubs or a deck skirt
- Dark rub marks where oily fur has polished a joist edge or pier
- Droppings with blunt ends, noticeably larger than mouse droppings
- Gnawed wiring or torn vapor barrier discovered during unrelated crawl space work
- Night-time scratching that sounds like it is coming from under the floor rather than overhead
How We Work a Rat Job
We begin under the house. The crawl space and the foundation perimeter tell us the population size, the travel routes and the entry points, and that assessment determines everything that follows. Trapping is placed along established runways, because a rat will not detour to investigate a trap set in open ground.
Once removal is underway we close the structure. Steel mesh and hardware cloth go into every gap that admitted an animal, and we replace failed vent screens rather than patching them. Norway rats gnaw through expanding foam and steel wool without much effort, so those materials do not appear in our repairs.
Why Greensboro Sees Rats Year-Round
The Piedmont's mild winters never really shut rodent activity down. Pressure spikes as overnight temperatures drop through October and November and animals that spent the summer in creek banks, storm drains and overgrown lots move toward heated structures. Properties backing onto greenways, wooded lots or older sewer infrastructure feel that shift first.
Because the population outdoors is continuous, a property that has been sealed properly stays clear while an unsealed neighbouring property keeps drawing new animals. Exclusion is the part of the work that lasts.
