I would like to know how people are dealing with the Jap Beetle invasion. They stripped the top 1/2 of my apple trees and are working on peaches. Sevin and permethrin will get rid of them for 4, maybe 5 days and they are back. The hormone attractants can attract other Jap beetles from half a mile away— you can collect thousands in soapy water buckets, but it does little to hinder their attacks.
Permethrin? Isn’t that used for texts? Just wondering because that’s what I use it for. Although I guess since it’s a pesticide it can be used for other things also.
I swear by ortho advance Tree and shrub pesticide. They also make a Garden version but all it is is weaker so you can use the tree and shrub version and just dilute it more. Unfortunately It will wipe out the bees. But if your tree is Past flowering then they would be OK. It also affects the fruits and vegetables so you have to look at their guidelines on when you can harvest after applying it.
I just noticed an invasion on my hazelnut trees. They are only three years old and about a third of the leaves were eaten. It takes quite a bit of that stuff to treat a tree, Especially if it is a good size. But I haven’t found anything that it hasn’t saved for me yet.
i meant ticks!
Sounds really bad. I have used those Beetle traps and hubby squashed them. I think he may have also washed them off with the hose and then drowned them.
The are really only bothering my rosa rugosa plant and we don’t use rose hips that often, so it was more of a pretty hedge type plant that we planted as an experiment. It has pretty roses.
We are going to have to go squirrel hunting - the jerks got all the apples before they were even beginning to ripen. Hubby didn’t think anything would bother them till they were closer to ripe and so he didn’t cover them.
Previous years the beetles decimated my raspberries, and ate the flowers off dad’s magnolia. This year I’ve seen maybe 2.
There are 2 likely possibilities for why they aren’t as bad this year. I’m hoping it’s because I had chickens out eating the grubs before they could grow up. JB grubs were my chickens’ first “live” food, and they still go crazy over them.
But it’s also possible that the weird spring weather interrupted their cycle. We had a late spring freeze that just hung around. It did a number on the songbird population, local news was asking people to put out mealworms because of how many robins were starving to death.
