Every spring, when I arrive at my northwestern Michigan cottage, I have to roust dozens of deer mice from winter complacency. Although I am quite fond of the peppy little creatures with their blazing white tummies, I draw the line at droppings on my kitchen counters and in my refrigerator, at gnawed-over soap, toilet paper shredded for nests, and neat gifts of shiny black seeds under my pillow, not to mention the pathos of little corpses all curled up in coffee cups.
Too, they can be carriers of the deadly Hantavirus, so I owe it to my family and guests to evict them.
Until this year, opening the cottage has always begun with an hours-long task of cleaning up their kitchen depredation, especially in the refrigerator: If I leave it open, there are mouse droppings; if I close it, there is mold. Then a very nice lady in the supermarket line gave me the secret password for cottage over-wintering: Bounce!
“Leave your fridge open, just fill it with sheets of Bounce – you can use them in your cupboards, too!”
The next spring, my refrigerator and cupboards were blessedly clean of both mice and mold.
Then there was the glorious May day when, delighted to be back Up North, I popped a piece of raison bread into my toaster, only to be assailed by the odor of toasted mouse. That’s what I thought I smelled when I used the oven for the first time, but when I searched inside I didn’t come up with a single baked mouse. Nonetheless, every time I turned on the oven, the sour, musty odor filled the kitchen, so I called in the appliance man.
“Mouse all right: not mouse mouse, I mean—mouse pee.”
“Thing is, it’s the insulation along both sides: they like to pee in it. Get in there, pee over and over, all winter long. What you need is a spray bottle, see? You could try bleach, or maybe white vinegar, or Cs-4? White vinegar, I think—one part in four. That should do it.”
That did it very nicely. When I turned up the oven for my meatloaf the odor had vanished, and after cleaning every surface with Lysol and plugging in zappers, I settled down for a mouse-free summer. Deterred by the odor of Bounce, they never crawled into the oven insulation again.
Musical Mice ♬ ♬ ♪
A mouse zapper is an electronic device (therefore of no use in the winter when the electricity is turned off) that emits exquisitely high-pitched sound waves inaudible to the human ear, but excruciating to a mice. Since they refuse to enter a room with one in it, these are humane devices to make sure mice stay outside of my cabin, all summer long.
Then I discovered that the acoustical sensitivities of these very same deer mice extend to musical appreciation. Very late on a moonlit spring night, a Canadian biologist recording bat communications picked up a lovely little trilling melody.* Almost supersonic, it was the mating song of a deer mouse singing his little heart out at the edge of the forest. After an interval (of assessing the musical quality of the love song and comparing it others she has heard?) a female took up her strain in an exquisite duet.
I began to worry about what my zappers might be doing to the sensitive and fine-tuned ears of these lovely little creatures, not to mention their emotional lives?
Alas, my skittish houseguests convinced me to leave the zappers plugged in.
I used to cut down the winter mayhem with a better mouse trap made from a large plastic bucket with three right angled entry tubes set in the lid. I filled it three quarters full of sunflower seeds and put it on my kitchen floor; the poor little things crawled in and ate themselves silly, perishing by dehydration.
“On the night that you were born,” my mother used to tell me on my birthday eve in a tone of lilting wonder, “there was a mouse in the wastepaper basket. Just as I went into labor, I saw his little pink ears sticking out.”
I’ve often wondered about that little creature, his ears translucent with the first dawn of my life on earth. Was he my herald angel?
In some cultures, there’s a belief that when you die your soul escapes in the form of a mouse. One terrible spring when my husband lay dying, I took a brief weekend away from the hospital to open the cottage. There was no hope at all, and before the week was up I would have to remove his life support.
On that bleak Easter morning, emptying my mouse bucket by the woodpile, I was offering words of regret and apology over the pathetic corpses when one tiny soul aroused itself to scurry away into the forest, as the sun dawned translucently through the golden veins of its ears.
