The Baltimore rodent problem.
Baltimore has a rodent problem that isn't anyone's fault, it's the city's geography. Older brick rowhomes with century-old foundations, dense alleys, shared trash, and a working harbor with cargo connections give mice and rats more ways into your home than almost any other East Coast city. The Department of Public Works runs a year-round rat-abatement program for a reason.
Rodents aren't a cosmetic problem. They gnaw constantly to keep their incisors filed down, and that gnawing destroys electrical wiring (a documented cause of structure fires), drywall, insulation, plumbing lines, and stored food. They reach breeding age in six weeks. A pair of mice in October is a population of fifty by Christmas if left alone.
Rodents carry Salmonella, Hantavirus, and Leptospirosis on their fur and in their droppings, and they're a primary host for fleas, ticks, and mites that then infest pets and bedding. The longer an infestation runs, the more contamination you're cleaning up after we remove it, which is why we treat every rodent call as time-sensitive.
Our rodent control process.
Rodent work is half pest control, half building science. We don't just put down bait, we map how the rodents are getting in and shut those doors. Here's the five-step process for every Baltimore rodent job:
-
Interior inspection & species ID
We walk every accessible space, basement, attic, kitchen, utility room, behind appliances, and identify droppings, runways, gnawing damage, urine staining, and grease marks. Droppings tell us species (mouse vs. rat) and how recent the activity is.
-
Exterior entry-point audit
Mice need a dime-sized opening; rats need a quarter. We circle the building and document every accessible entry point: utility line penetrations, vent gaps, weep holes, sill plate gaps, deteriorated mortar joints, garage door corners, gable vents.
-
Trapping & bait station placement
Interior activity is handled with snap traps placed in active runways, fast, targeted, no contamination. Exterior pressure is handled with tamper-resistant locked bait stations placed where rodents travel, never where pets or children can reach. We use the bait class with the lowest secondary-poisoning risk.
-
Exclusion & sealing
We seal accessible entry points with copper mesh, steel wool, and silicone, rodent-resistant materials, not foam. For larger structural gaps (deteriorated mortar, damaged siding) we provide a written list so you can have a contractor handle the structural fix.
-
Free follow-up & written guarantee
Every rodent job includes a free 14-day follow-up to refresh stations and verify activity has stopped. The standard guarantee covers re-treatment for 60 days. Quarterly Plan members get ongoing rodent coverage with unlimited free re-treatments.
What's included & pricing.
Rodent Control includes:
- Interior inspection and droppings/runway audit
- Exterior entry-point inspection with written report
- Trapping in active runways (interior)
- Tamper-resistant bait stations (exterior)
- Basic exclusion work on accessible entry points
- Free 14-day follow-up visit
- 60-day re-treatment guarantee in writing
Final price depends on infestation severity, building size, and the number of entry points requiring exclusion. Multi-unit and commercial properties are quoted separately. Large structural exclusion work (damaged siding, deteriorated mortar) is referred to a contractor, we'll tell you exactly what needs fixing before we close out the job.
If you want ongoing protection rather than a one-time treatment, the Quarterly Protection Plan ($49/month) covers rodents plus general pests with unlimited free re-treatments between scheduled visits, the most efficient option for rowhomes and properties on rat-pressure blocks.
Baltimore neighborhoods we treat weekly.
Rodent pressure varies by block in Baltimore. We run weekly routes through the metro and know which neighborhoods see the heaviest pressure (Fells Point, Federal Hill, Hampden, and Mt. Vernon, in case you're wondering). Same-day or next-day service in:
We also serve the wider DMV, Columbia, Silver Spring, Bethesda, Rockville, Annapolis, Frederick, and Northern Virginia.
