What are you guys/gals doing for SLF management?
I have peaches mainly. What are your personal opinions on when to spray and what to spray? I’m thinking permethrin as usual. Any tips appreciated. They’re here in NE Ohio now and want to be proactive, but not over active.

Grow sacrificial grapes as a trap crop.

I have been doing nothing; they have not made a big impact on anything so far for me. Well, early in spring I sprayed soap on them. If you have a lot of the nymphs in a local spot, insecticidal soap works very well.
Yes we have plenty of them. Here is a tree of heaven in the neighbors yard:

Good shit. Thanks for the info. It’s a shame…they sure are pretty.
Yeah they love tree of hell. I remember reading a story that a lot of predatory insects, birds, and chickens are making meals out of them now. But toxins from TOH can make them unappealing like monarchs with milkweed and zebra swallowtail with pawpaws.
I don’t see the point in recommending to people to go out of their way to squash them all. They’re here to stay now. Rip out as much TOH as possible and let the smaller insect eaters gobble them up.
As for in the orchard, like Scott said, your mileage may vary. If they’re not out of control or noticeably growing in numbers I wouldn’t go too far beyond what your normally do.

I had them all over my grapes last year. The nymphs seemed to like watermelon as well. I just squished them. They killed two of my neighbors Japanese maple trees. Haven’t seen many this year besides on TOH and possibly black walnut and honey (or black I can’t tell them apart) locust in an abandoned lot.

I live a few miles from where they were initially introduced (Berks County, PA). The trend is usually they are pretty numerous for a year, maybe 2, then fade to be a nuisance as wildlife figures out they are edible.

Same scenario here. First year they appeared there was a few. Second year there were hundreds. Years after that I only saw a couple here and there. I also killed the trees of heaven on my property the year i had the biggest population. Poison was the way to go. If you just cut them down they will pop up all over the place! I had some babies pop up over 75 feet away from a mother tree. If you face that scenario pull them out of the ground as soon as they pop up. Kinda like whack a mole on a much more grand scale!
