First of all, I believe we have so many more Japanese beetles and other worms and insects This year is because we had such a mild winter. At least that is what I read in a gardening article. They not only love my roses, but can't get enough of my Crepe Myrtle trees. I have found that using the jet spray on my hose to knock them off each day helps. Trouble is it must be done every day because they keep coming back. I not only had more of them this year, but they seemed to stay around longer than usual. Thankfully, the roses and myrtle trees are the only thing they seem to like in my garden.
