After a balmy fall, the television weather report promised near record cold and snow in three or four days. Mice don’t have televisions but somehow, they knew this because several of the tiny mammals successfully entered our house just before cold arrived. One scurried across the floor as we were reading the morning newspaper.

Years ago we read our then young children a delightful book about a mouse in the house. The story goes: “There is a mouse in the house. It is a very nice mouse.  It has a long, long tail and shiny eyes. My mother likes the mouse. But, she says, ‘A mouse does not belong in a house.’”

We agree and have developed a strategy to keep them out – at least most of them.

One tactic we do not do is poison. Karla Bloem of the International Owl Center in Houston, MN, reminds us that poison spreads.  When a predator eats a poisoned mouse, it absorbs the poison.  Over time, the poison builds up and kills the predator. People end up with more mice that can cause problems.

Here’s what we do at Winding Pathways:

  • Encourage predators. We love to hear the barred owls call on dark evenings, and occasionally we spot a red-tailed hawk in a tree out the window. Both are outstanding mouse catchers. Owls work the night shift and hawks the day.
  • Keep food secure. If mice smell dinner they’ll come right in uninvited and help themselves. It’s important to never leave food out unprotected. We store grain, flour, pasta, cookies and other foods in metal or stout plastic containers with tight-fitting lids. We don’t leave fruits and vegetables on countertops.
  • Tighten up the house. Before it gets cold, we check our house over carefully. Any narrow cracks get filled with caulk.  If we find a wider crack, we fill it with expanding foam. Often entry points for mice and insects are around pipes and wires leading into the home. Caulk and expanding foam help seal off the entry.   Drain pipes sometimes are entry points. “Chore Girl” type metal cleaning pads work great for filling pipes where liquids or air needs to come and go. Wad up the metal pads and jam them into the pipe. Spaces in the cleaning pads let air and moisture enter or leave but keep mice out.
  • Bring out the traps. Despite our best efforts, some mice make it into the house. Usually, we don’t see them but do see their calling cards – their tiny black droppings.

Effectively setting traps

Old fashioned mouse traps still catch mice efficiently, but a few tricks make success more likely. (With the exception of the poison information in this website, we have found this information to be appropriate.)

Bait. Probably the best bait is peanut butter. It just takes a tiny dab on the trigger to work.

Placement. Where you set traps is important. Mice naturally run along walls and dart under counters if they can. Traps set in the middle of a room are less likely to catch mice than those set along a wall with the trigger on the wall side.

Mouse traps

Place several mouse traps where mice tend to enter.

Double up. It’s usually most effective to set several traps in the same spot. So, set two or three touching each other. The first trap or two might not catch the mouse.  Usually one will

Keep setting the traps until you catch no more mice. Often people assume they have one mouse, but likely, there are more.  Keep trapping until they’re all gone. We dispose of dead mice by simply tossing them outside for our local opossum to eat. They can be flushed down the toilet.  Always be sure to wash your hands after handling mice or traps.
