Mice multiply fast — one pair can produce 60 offspring per year. You need to act quickly and use the right combination of traps and exclusion to stop an infestation.
Mice can squeeze through a dime-sized hole. Check around pipes, the foundation, door gaps, and utility lines. Mark every hole you find.
Use 6–12 Victor snap traps in your home — not 2. Place them along walls (mice run along walls), behind appliances, and under sinks. Peanut butter is the best bait.
Remove dead mice promptly (use gloves). Mice can die in traps and decompose, attracting flies. Reset immediately.
If traps alone aren't working, place Contrac Blox in bait stations in attics, crawl spaces, and garage corners. Never in living areas where pets can access.
Once activity slows, seal every hole with steel wool and expanding foam, or metal flashing. Mice can chew through foam alone.
Mouse droppings can carry hantavirus. Wet down droppings with bleach solution (don't vacuum), wear a mask, and wipe up. Deep clean affected cabinets.
Keep vegetation away from your foundation. Store food and pet food in metal or glass containers. Check your perimeter seasonally.
Mice droppings are small (like rice grains, 3–6mm). Rat droppings are larger (12–20mm). Mice gnaw small clean holes; rats chew larger ragged openings. Rats are less common indoors.
Yes. Mouse droppings can carry hantavirus (rare but serious), Salmonella, and Leptospirosis. Always wear gloves and a mask when cleaning them up.
One mouse sighting often means more. Mice are social and breed rapidly. Treat aggressively from the start — don't wait to see if it goes away on its own.
Classic Victor metal snap traps catch the most mice. Electronic traps (like Victor M250S) are cleaner but pricier. Glue boards are inhumane and less effective — avoid them.
No. Unless their food source disappears (which is unlikely in most homes), mice will stay and breed. Active elimination and exclusion are required.
