Rat & Mouse Problems in Great Bridge Homes
Rat and mouse problems in Great Bridge homes usually come down to small entry points on a detached house, so a Great Bridge inspection starts at the garage, the roofline and the places where utility lines pass through the walls. The neighborhood’s housing explains that order.
City Hall at 306 Cedar Road, the Great Bridge Community Center on Holt Drive and Great Bridge Lock Park on Locks Road all carry 23322 addresses. ZIP lines don’t follow neighborhood lines, though, and some Great Bridge streets fall in a neighboring ZIP area. Census Bureau American Community Survey estimates for 23322, the ZIP code area that covers much of Great Bridge, describe a place built almost entirely as family houses:
| 23322 ZIP code area (ACS 2020 to 2024) | Share of housing units |
|---|---|
| Single-family, detached or attached | 95.7% |
| Single-family detached | 87.3% |
| Built 1980 or later | 77.4% |
| Built 2000 or later | 26.2% |
| Built before 1960 | 5.4% |
That 95.7% single-family share is the highest of any ZIP area on our location pages, and 87.3% detached is about 20 points above the citywide 67.4%. The Census figures cover the whole ZIP area and carry margins of error; they are not a rat count, and no house gets rats because of its build year. What they predict is the building we will usually walk around: a detached home from the last four decades, with its own garage, roofline and service entries and no shared walls.
The neighborhood takes its name from a wooden causeway across 360 yards of marsh and open water on the Southern Branch of the Elizabeth River. The first pitched battle of the Revolutionary War in Virginia was fought there on December 9, 1775, according to the Virginia Department of Historic Resources, and the battle site has been on the National Register of Historic Places since 1973. Today Battlefield Boulevard crosses the Atlantic Intracoastal Waterway on a City-operated twin bascule bridge, built in 2004, that carries about 35,000 vehicles a day and opened 3,136 times in 2024. The 19-acre Great Bridge Lock Park sits beside the lock just off the boulevard.
Our rat control service covers Norway rats, which burrow and stay low, and roof rats, which climb. House mice are handled through mouse control, because the gaps they use are much smaller.
Crawl Space Rodent Control in Great Bridge
Where a Great Bridge house has a crawl space, we inspect it on every job. Census data doesn’t record foundation type, so we find out at your house rather than assume.
On a house from the 1980s onward, the crawl space checks are usually about service entries and access rather than failing masonry:
- foundation vents and whether their screens are intact
- the crawl space access door and its frame
- gaps where plumbing, HVAC and electrical lines enter
- cracks or breaks in the foundation wall
- burrows along the outside of the foundation, where Norway rats dig
The City of Chesapeake’s Property Maintenance Code says foundation walls “shall be maintained plumb and free from open cracks and breaks” and kept so as “to prevent the entry of rodents and other pests.” A foundation gap is a maintenance item as well as a pest item. Our crawl space rodent control page explains the work under the floor, which has no fixed price until the inspection.
Attic Rat & Mouse Removal
Rats and mice in a Great Bridge attic come out by trapping and stay out once the roofline gaps they used are sealed. University of California IPM notes that roof rats favor attic spaces, walls and false ceilings.
On a detached two-story house, the weak points tend to be where roof planes meet: soffit returns, gable and ridge vents, and the joint where a garage roof ties into the main house. Trees count too. UC IPM advises removing overhanging limbs within 6 feet of a roof so rats can’t reach the roof top and get into attics and soffit vents. Attic rodent removal is priced after inspection.
Rodent Exclusion & Entry-Point Sealing
Sealing the entry points is what stops a Great Bridge rodent problem from coming back. UC IPM says every hole larger than 1/4 inch should be sealed to keep out both rats and mice, and that a rat can get beneath a door with only a 1/2-inch gap.
With nearly nine in ten homes in the 23322 area detached, the garage gets the closest look. A worn bottom seal on the garage door, or daylight under the garage-to-house door, is all a rat needs. Houses also open up over the years: a cable installer drills a new hole, or a dryer vent flap stops closing.
Each opening is filled with a hardened material matched to its size; foam or steel wool alone gets chewed through. Doors get sweeps, and brick weep holes and vents get screens that still let water drain and air move. Our rodent proofing service explains what a full exterior seal includes.
Signs You Need Rodent Control
You need rodent control if you find any of these around a Great Bridge home:
- Droppings in the garage or attic: mouse droppings are 1/8 to 1/4 inch long; roof rat droppings about 1/2 inch; Norway rat droppings 3/4 to 1 inch (Cornell).
- Noise over the ceiling or the garage at night: scratching or running in the roofline.
- Chewed car wiring: UC IPM notes rats commonly gnaw the insulation on engine wires, worth checking if you park in the garage.
- A hole beside the foundation or driveway slab: a possible Norway rat burrow.
What a Visit Costs
Most Great Bridge calls fall in our $99 to $250 per-visit range. A mouse problem in a newer house is usually a mouse inspection and treatment visit at $99 to $149. Rats run $150 to $220 per treatment visit. Sealing the garage, roofline and service gaps is exclusion and proofing at $180 to $250, and a follow-up visit is $99 to $120.
Attic and crawl space jobs, and any cleanup, depend on what the inspection turns up, so they are priced then. Whatever the visit, the technician gives you the exact figure on your callback before you book.
