I inherited a small patch of roses, which had the Japanese beetles in the first year. After reading about biological controls and methods, I did the following to keep my yard clear of these harmful insects.
1. I sowed a patch of onion and garlic chives along the borders of the roses. The beetles don’t like these plants.
2. I sowed cilantro and let it flower near the rose bushes.
3. I sowed a thick patch of clovers and overwintering plants.
4. I grew a patch of Shasta daisies near the roses.
I do not have any Japanese beetles anymore. Let me explain how.
1. The Tachinid fly is the natural parasitical predator of the Japanese beetle. It is attracted by the dill and aster family flowers. It likes small aromatic flowers of carrots, cilantro, and Shasta daisies.
2. Overwintered plants create nematode populations that decimate the bug larvae.
3. The bushes of fruiting hollies at the hedge brought in a steady population of birds that also ate up the larvae.
4. What was set up as a rose patch, I converted to a mixed patch. There are now cilantro, chives, turmeric and evening primrose growing in that patch with roses.
Try some natural longer lasting remedies.
