Everything was fine Sunday morning, by Wednesday afternoon almost two-thirds of the leaves had been shredded:
I quickly made up a small batch of Captain Jack’s Dead Bug and liberally applied it to the leaves and especially the beetles, soaking them thoroughly. However, apparently Japanese Beetles drink Spinosad for breakfast as they continue to do what they do a day later.
I took full advantage of my opposable thumb and applied a time-tested manual beetle eradication technique. I am not convinced that makes us smarter than them. Our advantage in using tools is far outweighed by their ability to procreate as evidenced above.
