They really like my rosa rugosa. We set out the hanging Japanese beetle traps, and they worked real well. I’ll have to try some tide.
I am allergic to tide though, so I’ll have to be careful mixing it.
I don't have a plan for the beetles this year other than cut off rose buds (what are left) soas not to attract so many. Or I just let them eat and not go out and look at it. They make me feel creepy.
So far I'm not allergic to it, have a relative who had a terrible rash when she had her baby. She won't buy it, of course. It was very hard to get rid of and was so bad she needed help with the baby. They always blamed it on Tide but she also would ream up bunches of lemons and oranges for the Vitamin C so it could have been that, too.
Good luck if you try it.
When it got bad, they would poke their heads through the vent holes which was disgusting. Then I was so afraid they would chew their way out I covered them with pieces of duct tape.
They are cruel because they slowly die in those things. I used to make rounds with soapy water. If I have to kill, I try to do it quickly. I have gotten so I will pinch them with my fingers or knock them off and stomp on them. Then I have to wash my hands well.
I am hoping in time they will develop something safe that doesn't have unintended consequences to eradicate them. I don't think they've hit the CA grapes and fruit and almond trees. You can bet if they get too pesky on the west coast, they will be very aggressive about finding an effective way to get rid of them.
There have been some experiments, won't go into it. Whatever you do, don't use anything with the neocontinoids in them like I did one summer, fortunately I saw right away what happened. They are now high on the list to blame for the loss of honeybees.
