    The beetles are really bad this year. I used neem oil once a week and that did it for me.

    Are Japanese beetles in ALL states? Or where are they the biggest problem?

      thanks, garlic powder. I am moving to a house that has tons of rose bushes and the beetles are terrible. the roses don't have any smell anyway. Not like the old ones. I sure do miss those.

    Beneficial nematodes work long term and do not harm plants, beneficial insects or animals. They kill the larvae, but it is too late to apply them now until fall. They don't kill the beetles. It is more preventative.
    We cannot use pesticides here, but I started using them before the ban, since the other products were toxic and didn't work.

    You need to kill them to make a dent in their population, or else they will come back even worse every year, as people said they lay ground eggs. Get a can or plastic tub and put water in it and a squeeze of liquid dish soap. Go out there at least once a day when they are all over the roses and carefully either shake the bush or brush them (wearing gloves) into the liquid. They will die. That is the only way my we made a dent on all our gardens in Michigan. Every year now there are fewer beetles in our yard.

    I have used Raid insect or ant killer...spray. Those pretty little beetles (?) drop off the plant and are never seen again....course you need to spray it often. They love roses, especially the buds. A non-chemical way would be better so maybe the water and dish detergent would be best. Will try that next summer.
