The fastest results come from this specific sequence:

• Day 1: Identify and seal entry points + deploy 8–12 snap traps along walls
• Days 2–3: Check and reset traps daily — first catches typically within 24–48 hours for an accessible mouse
• Week 1: Most accessible mice caught
• Week 2: Any remaining mice become harder to trap — if still active after 10 days, call a professional

Speed for one mouse: snap trap with peanut butter against the wall where you saw it — 24–48 hours. Speed for an infestation: sealing + multiple traps + potentially professional exclusion — there is no single-day solution for a colony.

Trap Placement Is 80% of Success

Place traps perpendicular to walls with the trigger end touching the wall — mice run along walls and step on the trigger naturally. Place a trap every 6 feet in active areas. Traps placed in open areas rarely catch anything.

Find and Seal Entry Points

Mice squeeze through holes as small as a dime (6mm). Check around doors, windows, vents, pipes, and the foundation. Seal with steel wool stuffed into gaps then covered with caulk — mice cannot chew through steel wool. Add door sweeps to exterior doors.

Eliminate Food Sources and Nesting Areas

• All food in airtight containers; no pet food left out overnight
• Clean crumbs and spills immediately; sweep under appliances
• Remove clutter from garages, basements, and storage spaces
• Fix leaky pipes

Use Traps Correctly

• Snap traps along walls, behind furniture, near droppings or gnaw marks
• Use many traps at once — more is better
• Bait with peanut butter; wear gloves when setting
• Check daily; dispose of dead mice promptly in sealed bags
• For humane options, live traps work but require release at least 1 mile away

When to Call a Professional

If mice are still active after 10 days of consistent trapping, the infestation is likely larger or has entry points you haven't found. Anchor Pest Services offers same-day inspections across Manchester, Nashua, and Concord — call (603) 785-0118.
