The Japanese beetles didn't wait for the Fourth of July to get their party started this year. The first wave of the invasion began in late June. Last week I noticed that the hollyhocks were looking especially tattered, leaves skeletonized, and petals chewed down to nibs. At high noon, under glaring sun, visible hordes of these scarabs from hell fly in like clumsy zeppelins toward their targets, with a dull buzz.
I abandoned my preferred beetle extermination technique of last year—the forefinger-to-thumb squish—after getting squirted with black beetle gut juice. (Which has also put me off squid ink pasta for quite a while.) Besides, this year there seem to be thousands of the filthy beasts. My heart sinks when I see a half-dozen of them massed on a single rose bud in a configuration approximating a dysfunctional corporate org chart.
In desperation, I tuned into the internet recently and read about someone who uses self-rising flour against the beetles. When ingested, the leaveners supposedly cause explosive, terminal gastric distress. (Ah, such a lovely thought.) I've given it a try, and haven't yet found evidence of its efficacy, but I can tell you that it really annoys a Japanese beetle to have a load of flour dropped on it, which alone is well worth it.
I'd also read that crows eat Japanese beetles (both the grubs and adults), but I haven't been able to persuade Heckyl and Jeckyl to take a break from their tire-seared squirrel carpaccio or their Wednesday-morning curbside garbage bag potluck.
But a momma house finch has come to the rescue. She swoops in from the neighbor's tall evergreens, scans the landscape, then bustles into the thicket of hollyhocks to go after beetle after beetle, a snack for which her seed-crushing bill is ideally suited. (Next time, bring your friends!)
