11 and counting (unfortunately)

I’ve discovered that the number 11 has many interesting characteristics: it is the first number that cannot be counted with a human's ten fingers. In English, it is the smallest positive integer requiring three syllables and the largest prime number with a single-morpheme name. It is also the smallest positive numerical palindrome. Displayed on a calculator, 11 is a strobogrammatic prime (it reads the same if the calculator is turned upside down) and a dihedral prime (it reads the same if the number on the calculator is reflected in a mirror). If a number is divisible by 11, reversing its digits will result in another multiple of 11. As long as no two adjacent digits of a number added together exceed 9, then multiplying the number by 11, reversing the digits of the product, and dividing that new number by 11, will yield a number that is the reverse of the original number. (For example: 142,312 x 11 = 1,565,432. 2,345,651 / 11 = 213,241.) Fascinating.

In thinking about the number 11, I was also reminded of this scene from Spinal Tap:  


If 10 represents the pinnacle of achievement, 11 is even better, right?

When I started writing this post a couple of days ago, 11 was the number of mice that we had caught in our house since October. This number is already obsolete however, as we have caught that many again and more.  (We could be having an interesting discussion about the smallest odd prime number that is not a twin prime.) This is very disturbing. We’ve had mouse trouble before—one here, one there—but never have we had an epidemic like this. We’ve tried all kinds of traps to great (ugh) success—traditional traps, glue traps, sticky gel traps with bait, sticky gel traps without bait, snap traps. Our bait of choice for the traditional traps and snap traps is peanut butter. Often the mice have eaten the peanut butter without springing the trap, but we just patiently spread some more on there, confident that they’ll be back. Once, we even caught two mice in one trap. That was kind of exciting. What hasn’t been exciting is hearing the mice climbing (and falling) inside our walls and scurrying across our kitchen ceiling. What hasn’t been exciting is catching the occasional live mouse and dumping it, with the trap, in a bucket of water to drown it (or finding one in the kitchen trash and whacking it to death). What hasn’t been exciting is removing everything from under the kitchen sink and drawers, cleaning out the little mouse droppings, washing everything thoroughly before putting it all back—and having to do it again two days later. What hasn’t been exciting is observing (with mounting anxiety) the mouse smell getting stronger, to the point where my eyes began to burn from the off-gassing of the mouse feces and urine. Okay, this is getting serious.

We racked our brains to try to think of any changes that recently took place that could have contributed to the increased infestation. We knew they were probably coming into the kitchen from behind the dishwasher, so tonight we pulled that out—the burning eyes was a good indication that, yes, they were definitely coming in through here. Some online resources suggested plugging any holes that were at least ¼” in diameter, or even smaller (are you serious?), with steel wool and sealing it with caulk. This is what I did. However, this didn’t solve the issue of how they are getting into the house.

We had some work done on our house this past fall as part of an income-based weatherization program through a local organization named Hope Community Builders. One of the things they did was remove the door of our attached garage, frame in and insulate the space and add a set of french doors. Because the garage is below grade, the workers added a drain in front of the new doors to keep water from entering and tied it in to a drain coming from the garage. Our guess is that the mice are finding their way into the garage through this drain, which then gives them access to the basement and the rest of the house. We now have an 8x8x12 piece of lumber sitting on top of a can of paint that is resting on top of the garage drain cover, blocking the (¼”) holes in the top.
