Stop Mice
Summary: Tips on how to stop mice from entering your home, plus steps to take once you have mice in the house.
Jen, Vancouver, Canada asks:
I have a hundred year old three-story house with a concrete foundation and partially finished basement, and for many years we have had a problem with mice. We trap them, but every fall when it gets cold, more come in from outside. Because they mostly live in the walls and ceilings, closing up the holes inside the house is not a viable option. I was wondering whether there is any way of sealing the house at ground level from the outside, so that they wouldn't be able to get in. Is this viable, and who should I call to have such a thing done? A mason? An exterminator? Thanks!
Dear Jen:
I, too, live in a 100+ year old home. Fortunately, I do not share your problem, but I can relate.
You can stop mice from getting in the house, but not without some effort on your part. Understand that mice look for places they feel protected. Inside the walls of your house is perfect. So, let's talk about how to discourage the mice from entering in the first place.

Mice love places to hide. Take a look along the foundation and be sure to cut down high grasses. Move stacks of wood away from foundation walls, as well. Birds are messy eaters, dropping lots of seed on the ground, so move bird feeders well away from the house. Bowls of pet food will also attract hungry rodents. Leaf litter and any other clutter needs to be removed.
A good mouse program sometimes requires a first-line of defense. The placement of rodent stations along the outside perimeter wall may be called for. I would suggest one rodent station every twenty five feet. You

As for the mice already residing inside the house, I would suggest snap traps and glue boards. Mice are easy to catch if you know how. Please read my articles on mouse proofing, mouse infestations and how to catch a rat.
I think a good brick layer can do tuck pointing and a garage door company can put a rubber seal on the bottom of the door. The installation of a high quality sweep on the bottom of pedestrian doors will also do the trick.
Hope this information helps.
