Victory is mine

For the past year or so, Kira and I have been increasingly conscientious about composting our food scraps. This has been, on the whole, a positive experience, and it has been pleasing to see the subsequent reduction in our weekly flow of garbage that gets hauled away from the curb.

I say "on the whole," however, because composting is not, at the end of the day, a bed of roses. The song of the lonely composter is, at best, bittersweet -- a mixed melody of virtue and sorrow.

I sing, dear reader, of fruit flies.

It started with the advent of warmer weather a few weeks back. We have been keeping a small, charcoal-filtered scrap bin inside near the kitchen trash cans. When preparing food or slicing up fruit to put on our cereal for breakfast, the location of the pail made it easy to get rid of the bio-waste as it was being generated. Throughout the cold months pf winter, this arrangement worked just fine. Come the summer, though, things started to change.

Without being too graphic, it got to the point where every virtuous lift of the lid on the small bio container brought its own "reward" of a small cloud of very active -- and hungry -- pests. It didn't take long for the strawberry tops and banana peels, doing their fetid business in the small green pail, to become a breeding ground for these harmless, but quite annoying, swarms.

What to do? What to do? Both Kira and I have been trying to avoid harsh chemicals lately. Allergies, general health, and a host of other concerns leave us leery of fumigating rooms or zapping the little bozos directly. We both, my wife and I, have been on a "home remedies" kick of late, and I was curious if there was a more "old world" solution to the problem then resorting to the wares of DuPont and Dow Chemical.

Turns out there is. After a little thinking, and some digging on the internet, I came up with this: take a shallow dish, fill it with a dash of port wine, stretch some cling wrap over the top, and poke a small hole in the middle with the blades of a scissors.

Some of you who know me, reading this, may recall that I have a particular fascination with the theme of monkey traps. Being a theologian, I think a lot about the workings of systems, and I am particularly interested by systems that are powered to deliver results on the basis of "lowest-common-denominator" operations. That is to say, I like systems that are so elegantly simple that they continue to work even when they are in what is known in the biz as a "failure condition."

For a system to work, even while its failing, requires the sober understanding on the part of the designer of some factor, outside the system, which can be depended upon to deliver a satisfactory result, regardless of the condition of the system. In the case of the monkey trap, that consistent factor is the short-term thinking of the monkey. Because the monkey cannot let go of the immediate desire to have the fruit or the nuts in the bottom of the trap, it gets caught -- and held -- by its own fist, refusing to let go of the treasure in the trap.

This fruit fly catcher functions using the same principle: the files are smart enough (and driven enough by the scent of the sweet, sweet wine) to get in through the hole, but they have no capacity whatsoever to get back out again.

The first morning, after laying the trap, there were ten flies floating in my little scarlet sea. Two days later, there are thirty, and I no longer spot pests on the wing here in the house.

Given all the catastrophic failure we have seen recently, I am encouraged by this. With a little thought and planning, systems can be designed to incorporate failure into their flow, so that even when they aren't directly "working," they can still work. Part of this, I think, involves a willingness to let go of active control, and to allow passive factors to operate.

Passive factors are not nearly as glamourous, of course. It would probably be a lot more macho and satisfying to grab that can of D-Con and zap each individual winged beastie in turn. But there's a lot of ways that that macho crap can fail, and pretty quickly. Can't be everywhere at once, in the first place. Second, the little pests might outbreed me, and develop a resistance to the chemicals. And finally there is the worry that I and my loved ones might not be as resistant to the chemicals as the bugs are (an ultimate sort of system failure, this).

What I love about the port-wine trap, in contrast, is that none of these factors drives the success of the system. All that matters is that fruit flies keep having a mad lust for fruit juice -- and I think its fair to say that nature is on my side with that one.

Take my advice, O reader: build to fail.
