Just over a week ago, home in the evening from a dayʼs work, I looked out our north window in the dining room and noticed that our linden tree looked peculiar in the topmost area. Later, I think that same day, I went around the house watering plants (a mandatory daily activity during our three-week drought, now strangely distant in the past even as rain falls while Iʼm dictating — northern Jackson and Dubuque, not to mention Galena, enduring a horrible thunderstorm-cum-tornado last night) and noticed the peculiarity was a laciness to the leaves, meaning some bug was eating them. The next night the damage had spread, and some gleaming green, chunky bugs flew in my face as I examined the tree — Japanese beetles.
I told Janet about my discovery when she got home from her workout, and she/we decided we had better do something immediately. So she trooped right down to Gasser True Value (yes, although we may hate their excessive accumulation of creosote-soaked, and creosote-fume-emitting, piles of logs, we do appreciate having a hardware store in town, although The Lovely One could just as easily have driven a little further to Theisenʼs), where she grabbed the last remaining Japanese beetle trap. Not calling on my USDA experience whatsoever, I assembled the trap following the directions on the outside of the plastic bag, hanging the bag from one of our tiki torch poles, and let the pheromone do its work.
The trap was to be placed at least thirty feet from foliage (impossible in our yard) and it summoned by scent hordes of horny male beetles seeking sex from further away than just our yard (thus the need to keep the trap in isolation, away from plants, to prevent those erratic bugs from accidentally happening upon other juicy leaves to devour near the trap). We put it at the end of our driveway, since our neighbors had pulled down their one tree several years ago. Boy, shoving the tiki post into the iron ground was a chore and a half (not so much now, when all the dirtʼs turned from skillet hardness to mud).
And the pheromone did work. By the next evening the bag was already almost half-full. And I had to dump the still half-alive mass of churning black insects a day later — an unpleasant chore that I think was made somewhat easier by my experiences searching purple traps for emerald ash borers. Iʼm just not as squeamish about buggy life as I once was.
With the rain beginning last weekend and continuing just about daily this whole week, the beetles have diminished in quantity, and we have only had to empty the trap one more time. So far.
Of course, we are also worried about what those fiendish bugs may have accomplished in their life cycles before we started alluring all the concupiscent males to the pheromone trap. Our concern means weʼre also going to try to spray the tree with insecticide and soapy water and try to treat the ground as well — to eliminate (as many as possible) eggs that have been buried.
This was one time accessing the Internet was a genuine benefit. Neither one of us really knew anything about what to do about Japanese beetles, but a quick search googled out what we needed to know.
If only this were the end of our petty woes…
