Rodent Control

Trapping, exclusion, and sealing for mice and rats, built to end the problem rather than just knock it back for a few weeks.

Rodent control gets mice and rats out of a structure and closes the gaps that let them in. It is one of the most common pest calls Maryland operators get from fall into winter, when cold weather pushes rodents toward any heated building they can reach.

Real rodent work is more than setting a few traps. Mice breed year-round once they are inside a warm house, so trapping without sealing the entry points just clears the current animals and leaves the door open for the next ones. Baltimore's connected rowhouse blocks make this harder: rats and mice travel building to building along the row, so exclusion on an older brick rowhouse is labor-intensive and has to be thorough. A proper Maryland rodent program pairs trapping with exclusion, since a mouse needs only a pencil-width opening and a rat needs about the width of a quarter.

What rodent control covers

  • House mice, the most common indoor rodent in Maryland
  • Norway rats, an established problem in Baltimore's rowhouse blocks and waterfront communities
  • Inspection to find entry points and the conditions feeding the activity
  • Trapping programs, set and monitored rather than left in place
  • Exclusion: sealing gaps with steel and hardware cloth, not just caulk
  • Advice on the food, clutter, and harborage that draw rodents in

What to expect

  1. 1

    Inspection

    The technician finds the entry points, runways, droppings, and nesting spots, and pins down how rodents are getting in.

  2. 2

    Trapping

    Snap traps and stations go in at the active runways. The operator monitors and resets them rather than leaving them and walking away.

  3. 3

    Exclusion

    Entry points get sealed with steel wool, hardware cloth, and proper sealant. This is the step that actually ends the cycle.

  4. 4

    Follow-up

    A return visit confirms the activity has stopped and catches any gap that was missed the first time.

What it costs in Maryland

An initial rodent inspection and exclusion assessment in Maryland runs about $100 to $300. A one-time treatment that includes trapping and baiting generally runs $150 to $500.

Exclusion work, sealing the entry points, runs $200 to $600 or more depending on scope. On older Baltimore brick rowhouses the exclusion is more labor-intensive, since the masonry has many gaps and rats travel the connected block, which moves the cost up. Ongoing rodent monitoring is included in many quarterly plans or runs $50 to $150 per standalone visit.

Norway Rat

The large, burrowing rat found near foundations, dumpsters, and sewer lines. Norway rats cause serious structural damage and carry diseases that pose real health risks.

Rodent Control: common questions

Why not just use poison bait?
Bait alone has real downsides indoors: a poisoned rodent can die inside a wall and create an odor problem, and bait does nothing to close the gaps the next rodent uses. Good rodent control leans on trapping and exclusion. Bait, where it is used at all, is a supporting tool, not the whole plan.
How long does it take to get rid of mice?
A typical mouse job in a Maryland home is brought under control over a few weeks: an initial visit, monitoring, and a follow-up. Severe infestations or homes with many entry points take longer.
Will sealing the house actually keep them out?
Exclusion is the part that lasts. A mouse fits through a gap the width of a pencil, so the technician seals pipe penetrations, gaps under doors, vents, and foundation cracks. Without that step, trapping only clears the current rodents.
Why are rats a block-wide problem in Baltimore?
Baltimore's rowhouse blocks share walls and connect along the alleys, so a rat colony can work an entire row. Treating one house while the rest of the block is infested rarely holds. Exclusion has to be thorough, and coordinating with neighbors helps.
