A mouse exterminator in Baltimore costs $200 to $600 for a typical infestation in a single home, and large or long-established populations can run past $1,000. Ongoing coverage is cheaper for most households, since Czar Guard plans bundle mice into a flat $39 to $75 per month. The inspection that produces your written price is free.
Those are Pest Czar’s published figures for the Baltimore metro, and the rest of this guide explains what sits behind them. You will see how one-time and recurring pricing compare, what pushes a quote up or down, what a complete mouse treatment has to include, and why trapping without sealing is money spent twice. This post covers mice only. If your evidence points to rats, which need different equipment and a different program, start with our guide to rat exterminator costs in Baltimore.
How Much Does a Mouse Exterminator Cost in Baltimore?
The price depends on whether you want the current population removed once or the problem handled year-round. The table below uses the figures Pest Czar publishes on its mouse control page, so you can compare them directly against the quote you receive.
| Mouse service | What it runs | What is included |
|---|---|---|
| Typical infestation, single home (one-time) | $200 to $600 | Inspection, trapping, sealing up to one linear foot, 30-day follow-up |
| Large or long-established infestation (one-time) | $1,000 and up | Same program with more trap placements, more sealing, and attic or crawl space attention |
| Czar Guard Basic (exterior) | From $39 per month | Quarterly exterior service, mice covered, one linear foot of exclusion annually, Guarantee |
| Czar Guard (interior and exterior) | From $49 per month | Adds interior service and interior rodent monitoring, 15 or more pests |
| Czar Guard Plus | From $75 per month | Adds specialty pests such as bed bugs, fleas, and carpenter ants |
| Initial inspection | Free | Written scope and price before any work |
For context, the Maryland pest control price guide lists general rodent treatments statewide at $150 to $500, based on Angi data. Baltimore mouse jobs land in the upper half of that range because rowhomes and older foundations have more entry points to find and seal. Every number above goes into writing at the free inspection, and Maryland’s 6 percent sales tax applies to the final price.
What Drives the Price Up or Down?
Two homes with the same scratching in the walls can get different quotes, and the difference almost always comes down to four things. Knowing them helps you read any estimate and tells you what you can change before the technician arrives.
- Entry points. This is the biggest driver. A 1920s stone foundation in Hampden or a Towson rowhome with shared utility chases has far more mouse doorways than a 2005 slab in a county subdivision. The CDC’s rodent exclusion guidance notes a mouse fits through a gap the width of a pencil, so the count of openings, not the size of the house, sets the sealing workload.
- How long the population has had to spread. Mice that arrived last month are in one wall void. Mice that arrived last winter are in the attic insulation, the kitchen kick plates, and the basement sill. More locations mean more trap placements and more follow-up.
- Exclusion footage. One linear foot of rodent-proofing is included with service. A home that needs several feet of copper mesh, hardware cloth, and cement across multiple openings is scoped separately. Our rodent exclusion cost guide covers that pricing in depth.
- Contamination and follow-ups. Attic or crawl space cleanup adds labor, and a heavily colonized house may need the full 30-day follow-up window rather than a single verification visit.
Home size matters less than people expect. A small rowhome with eight unsealed penetrations is more work than a large colonial with two.
Is Exclusion Worth Paying For?
Yes, and it is the part of the job that separates a quiet decade from a quiet month. Trapping removes the mice that are inside today. Sealing stops the field-born mice that will try the same gap next October. The CDC describes effective rodent control as sealing, trapping, and cleanup working together rather than relying on any single tactic, and the University of Missouri Extension calls mouse-proof construction the most successful and permanent form of house mouse control.
Pest Czar includes up to one linear foot of exclusion with every service and every Czar Guard tier. If a home needs more than that, the inspection quotes the add-on work. The rodent exclusion cost guide explains what sealing a Baltimore home involves and how it is priced, so this post stays focused on treatment.
What Should a Mouse Treatment Include?
A complete mouse treatment has four parts, and a quote that skips any of them is a quote for a repeat visit. Here is what Pest Czar’s program delivers, visit by visit.
- A full inspection. The technician traces the house the way a mouse does, along the foundation at grade, up gas, AC, cable, and water penetrations, across the garage door seal, and into the basement sill plate. Interior checks cover the kitchen perimeter, appliance voids, pantry, closets, attic, and crawl space. Every opening is documented.
- Population control on the same visit. Snap traps go into wall-adjacent runs and enclosed placements, glue boards monitor low-traffic zones, and secured bait placements are used only where trapping alone cannot keep up. Placements are chosen with children and pets in mind.
- The sealing pass. Documented openings are closed with copper mesh, hardware cloth, caulk, foam, and cement. Steel and mesh matter because mice chew through foam alone.
- A 30-day follow-up. One-time work includes a return visit inside 30 days to check trap results and look for fresh sign. Plan members get free returns between quarterly visits whenever activity resurfaces.
Droppings cleanup has its own rules. The CDC’s cleanup protocol warns against dry-sweeping or vacuuming droppings, which puts particles in the air, and recommends soaking them with disinfectant first. Leave the evidence in place until the inspection, though, because droppings and gnaw marks are the map the technician reads. If you want to know where to look, our guide to where mice hide inside your Baltimore home walks room by room.
DIY Traps vs. Professional Service: The True Cost Comparison
Store-bought traps are cheap, and they do catch mice, so the question is not whether DIY works at all. The question is what it costs when it only half works. A pack of snap traps and a tube of caulk runs well under $50, which looks unbeatable next to a $200 to $600 service call.
The math turns when the colony persists. Missouri Extension notes that a mouse control program usually takes at least two weeks to complete and that traps only work when placed where mice are actually living, which is the part most homeowners guess at. Retail traps remove individual animals while the entry stays open and the void stays occupied, so the scratching returns, more product gets bought, and the eventual professional visit still happens. Chewed wire sheathing during those months is the expensive outcome nobody budgets for.
Poison baits are the worst DIY choice indoors. Mice die inside walls, the odor lingers for weeks, and the bait is a hazard to kids and pets while doing nothing to close the gap.

How Fast Can a Technician Come Out?
Often the same day. Pest Czar dispatches from its Towson headquarters at 1016 Cromwell Bridge Road, which keeps response tight across Baltimore City, Baltimore County, and the surrounding counties, and same-day slots are available when the schedule allows. Call (443) 377-3365 to check today’s availability.
The inspection is free and the technician who arrives is a state-certified applicator, not a salesperson. You get every entry point documented in writing and a price before anything is set. Mice reproduce fast enough that a pair in November is a colony by February, so the cost of waiting is real.
What Does Czar Guard Cover for Mice?
Every Czar Guard tier covers mice, including the $39-per-month Basic plan. Basic delivers quarterly exterior service, spider web removal, one linear foot of rodent-proofing annually, and the Pest Czar Guarantee, which puts a technician back on site between visits at no charge if activity returns. Czar Guard at $49 adds interior service and interior rodent monitoring, which is the right tier for rowhomes and older county houses that will always have another gap to find. Czar Guard Plus at $75 adds specialty pests. Full details are on the residential pest control page.
Pest Czar is a woman-owned, QualityPro and GreenPro-certified exterminator based in Towson since 2013 with an A+ rating from the Better Business Bureau. See the mouse control service, visit the rodent control hub if you are not sure whether you have mice or rats.
FAQs
How much does it cost to get rid of mice in Baltimore?
Pest Czar charges $200 to $600 for a typical single-home infestation and $1,000 or more for large or long-established populations. Czar Guard plans cover mice from $39 per month. The inspection is free and produces a written price.
Is a one-time mouse treatment or a monthly plan cheaper?
For an isolated problem in a tight house, one-time service at $200 to $600 is the right buy. For rowhomes and older homes that will keep producing gaps, Czar Guard at $49 per month costs about the same as one emergency visit per year and adds quarterly service, interior monitoring, exclusion, and free returns.
What is included in a professional mouse treatment?
A documented inspection of the exterior and interior, trapping and monitoring placed where mice actually travel, sealing of entry points with copper mesh and hardware cloth, and a follow-up visit inside 30 days to confirm the population is gone.
Does the price include sealing entry points?
Up to one linear foot of rodent-proofing is included with every service and every Czar Guard tier. Homes that need more sealing are quoted for the additional footage at the inspection.
How much does a mouse inspection cost?
Nothing. Pest Czar’s inspection is free and includes a written scope and price before any work begins.
Do I have mice or rats?
Mouse droppings are about a quarter inch long with pointed ends, and mice squeeze through pencil-width gaps. Rat droppings are around three quarters of an inch with blunt ends. The rodent control hub helps you tell them apart, and rats are priced in a separate guide.
How long does it take to get rid of mice?
Most homes go quiet within one to two weeks of the first visit as trapping clears the residents and sealing cuts off reinforcements. Heavily colonized or very porous structures may need the full 30-day follow-up window.
Can I just use store-bought traps?
You can catch individual mice, but retail traps do nothing about the open entry point or the occupied wall void, so the problem usually returns. Poison baits indoors are not recommended because mice die in walls and the bait is a hazard to children and pets.
Is it safe to vacuum mouse droppings?
No. The CDC advises against dry-sweeping or vacuuming droppings. Wear gloves, soak droppings with disinfectant, wipe them up with paper towels, and disinfect the surface. Leave droppings in place until after the inspection, since they show the technician where mice travel.
Does Pest Czar offer same-day mouse service?
Yes, when the schedule allows. Technicians dispatch from Towson across the Baltimore metro, and you can call (443) 377-3365 to check same-day availability.
