Why Hampton Roads Is Seeing a Summer Rodent Surge

​Ask most people when to worry about mice and rats, and they’ll probably say fall or winter—that first cold snap when rodents come scurrying indoors looking for warmth. It’s a fair assumption. It’s also incomplete.

Over the past two weeks, rodent-related calls to Getem Services have increased 90% compared with the previous two-week period. We’re hearing from homeowners across Hampton Roads: signs of rats at a Virginia Beach property, mouse droppings in a Norfolk rental, attic and crawl-space activity in Chesapeake, and infestation concerns from across the harbor in Hampton.

Multiple cities, one clear pattern—and it’s happening in the middle of summer. So what’s going on?

Summer Conditions Help Rodent Populations Grow

Here’s what most homeowners never see: summer conditions can build rodent pressure long before temperatures begin to drop.

Warm weather, dense vegetation, gardens, compost, pet bowls, and unsecured trash can give outdoor rodents abundant food and cover. When conditions are favorable, mice and rats reproduce quickly.

House mice already living inside a structure can reproduce at any time of year. Outdoors, however, plentiful summer resources can allow rodent activity to grow quietly in yards, sheds, woodpiles, and burrows around foundations.

That’s why the fall “invasion” homeowners brace for may not be the beginning of the problem. It can be the point when a population that has been active nearby becomes more visible indoors.

But that timeline isn’t fixed. A stretch of heavy rain and summer storms can disrupt outdoor nesting sites and move that indoor activity forward—and that may be contributing to what we’re seeing now.

What’s Driving Rodents Indoors Right Now

Hampton Roads has two things happening at once: months of warm-weather rodent activity, followed by repeated storms disrupting many of the places rodents use for shelter outdoors.

Lately, the weather has been adding pressure. Since late July, Hampton Roads has seen repeated heavy downpours, flash flooding and stretches of intense heat and humidity. When the ground becomes saturated, burrows along foundations and beneath sheds and decks can flood, pushing rodents toward nearby crawl spaces, garages, and wall voids.

Between storms, those same structures offer sheltered nesting areas, dependable water, and accessible food.

The Norfolk Health Department identifies house mice, Norway rats, and roof rats as rodents of public-health concern in the city. Their habits differ:

• House mice exploit small openings around foundations, exterior doors, and utility lines. Once inside, they commonly settle in walls, cabinets, storage areas, and other secluded spaces near food.
• Norway rats tend to stay low, burrowing along foundations and beneath sheds, decks, and debris. Crawl spaces and lower levels are common destinations when outdoor burrows are disturbed.
• Roof rats are agile climbers. They use trees, fences, and rooflines to reach attics, eaves, and other upper openings.

Most of the recent calls to Getem involve mice: droppings in cabinets, scratching inside walls or activity returning a few weeks after the problem appeared to be handled. Several calls involve established infestations rather than a single mouse that wandered inside.

Mice aren’t the whole story, though. Rats have appeared in this run of calls as well, including confirmed activity at a home in Virginia Beach.

The timing does not prove that the weather caused every rodent problem. But the sharp increase in calls suggests that repeated heavy rain may be adding pressure to an already active outdoor population.

Crawl spaces deserve particular attention after a stretch like this. They offer rodents secluded shelter, and heavy rain can also leave them damp. Rodent activity and excess moisture are separate problems, but they are worth checking for at the same time.

How to Keep Summer Rodent Activity From Becoming a Fall Infestation

The recent increase in calls does not mean every Hampton Roads home is infested. It does mean this is a smart time to remove the conditions that make a home easy to enter and rewarding to stay in.

• Remove easy meals. Store pet food in sealed containers, bring food and water bowls in overnight, secure trash and compost bins, and clean up spilled birdseed, fallen fruit, and food residue around grills.
• Reduce shelter near the house. Keep grass and vegetation trimmed, clear leaf piles and yard debris, and store firewood raised off the ground and away from the structure.
• Inspect the exterior after heavy rain. Check the foundation, utility penetrations, crawl-space vents, exterior doors, roofline, and gaps around windows. According to the Virginia Department of Health, mice can use openings approximately ¼ inch wide, while rats can enter through openings around ½ inch wide. Use metal mesh, flashing, or another gnaw-resistant material to close gaps rather than relying on foam alone.
• Look and listen for evidence. Watch for droppings, gnaw marks, nesting material, greasy rub marks, and scratching sounds. Pay particular attention to kitchens, garages, attics, and crawl spaces.
• Handle droppings safely. Do not sweep or vacuum dry rodent waste. Wearing gloves, wetting contaminated areas with disinfectant, and wiping up debris rather than stirring it into the air are the recommendations of health experts.

If you notice fresh droppings, gnaw marks, scratching sounds, or recurring activity, it’s time for a professional rodent inspection. Addressing the problem early can help keep a summer rodent issue from becoming more established before fall.

Professional Rodent Control in Hampton Roads

Getem Services has been protecting Hampton Roads homes and businesses from rodents since 1922. The calls we’re seeing right now are a good reminder that mice and rats don’t follow a fall-only schedule—especially after repeated summer storms.

Our rodent control process starts with a thorough inspection of the interior and exterior of the structure, including accessible attics and crawl spaces. We look for active rodents, nesting areas, conducive conditions, and the openings they may be using to get inside.

From there, we develop a rodent control solution tailored to the property. Depending on what we find, that may include interior trapping, exterior bait stations, exclusion work, and follow-up visits.

Rodent pressure around a property can change with the seasons, weather, landscaping, and activity on nearby properties. Homeowners who want continued monitoring and broader year-round coverage can sign up for Getem’s quarterly home pest control plan. The plan covers mice and rats, as well as ants, spiders, and other common household pests.
