How Rodent Control Works

Every job starts with a full interior and exterior inspection, because the plan for your house depends on what that inspection finds. We follow the runs, read the droppings, check for burrows along the foundation and mark every gap, vent and gnaw-point on the building.

Chesapeake shapes where we look. According to U.S. Census Bureau estimates, 81.0% of the city’s housing units are single-family and 68.3% were built in 1980 or later, so most inspections here are on detached suburban houses. On those homes we check:

• Garage door seals and the gaps between the garage and the living space
• Brick-veneer weep holes
• Soffits and roofline returns
• HVAC lines, dryer vents and utility penetrations
• The crawl space, which we inspect on every job

Older streets change the picture. In the ZIP code area that covers much of South Norfolk, 32.7% of housing units were built before 1960, and there we spend more time on foundation framing and older vents.

Small gaps count. University of California IPM guidance is that all holes larger than 1/4 inch should be sealed to keep out both rats and mice. The inspection tells us which rodent you have, where it is active and how it is getting in, and that decides the rest of the plan.

Removal targets the population that is in or around the house right now, and the method depends on the species. For mice, we use humane trap and bait placement inside the home. For rats, we treat burrows and nesting sites and place exterior bait stations. Every catch is removed and disposed of by us, not left for you to deal with.

Species matters for placement. UC IPM notes that roof rats usually nest above ground in attics, walls and false ceilings, while Norway rats burrow along foundations and live mostly at ground level. A roof rat plan and a Norway rat plan put traps and stations in different parts of the same house.

Rats are also cautious. UC IPM reports that they often avoid new traps and baits for the first several days, and sometimes weeks, which is one reason the process includes a follow-up visit rather than a single drop-off. You can see how removal fits with our other Chesapeake rodent control services before you book.

Sealing is what stops the next group of rodents from using the same gaps. Once the active population is being dealt with, we seal the exterior with hardened materials sized to each gap, not foam or steel wool alone.

Exclusion work on a Chesapeake house can include:

• A full exterior seal of gaps and vents
• Door sweeps, since UC IPM notes rats can squeeze beneath a door with only a 1/2-inch gap
• Vent and weep-hole screening that keeps airflow and drainage working
• Exclusion carpentry and foundation repair where the structure itself is the problem

House mice can get through openings as small as 1/4 inch, according to UC IPM, so small gaps around pipes and wires get the same attention as obvious holes. For the full scope, see our rodent proofing and exclusion service.

The follow-up visit confirms whether activity has stopped and adjusts the plan if it has not. We recheck the traps and bait stations, top up bait stations where they are in use and change the treatment if signs of activity remain.

This is where a cautious rat or a missed gap shows up. Fresh droppings, moved bait or new gnawing tell us something is still active, and we adjust before signing off on the job.

Cleanup is needed when rodents have left droppings, urine or nesting material in an attic, crawl space, garage or wall void. Removal and sealing stop the activity, but they do not remove what was left behind.

The CDC advises against sweeping or vacuuming rodent urine, droppings or nesting materials, because that stirs them up. If the inspection finds contamination, we tell you where it is and how much there is. Cleanup has no published price; it is priced after the inspection. Our rodent cleanup service explains what it covers.

At the end of the job, the technician walks you through what was found, what was removed and what was sealed. You should finish the visit knowing:

• Which rodent was in the house and where it was active
• How many catches were removed
• Every entry point we sealed
• Where traps or bait stations remain, if any
• Whether a follow-up visit is booked

A visit with Chesapeake Rodent Control costs between $99 and $250, depending on the service and the property. These are our published per-visit prices:

Cleanup, crawl space work and attic removal are priced after inspection. A technician confirms the exact cost for your property during the callback, before anything is booked. For a fuller breakdown, read our guide to rodent control cost in Chesapeake, VA.
