What’s great about stickers and using copper is you can see the copper once on the tree. So it’s easy to evaluate product. I have only tested Nu Film and Turbo, and Nu Film lasts a lot longer up to 3 months. Turbo the copper lasts a bit, a couple weeks maybe, at best. Depends, each year is different weather. So just my opinion that the snow won’t matter with Nu Film, but probably will with Turbo. It does not have the staying power of Nu Film.
Scott Smith observed the staying power too and spoke about on this site. As did I with photos to show the copper at the time. What really impressed me is when is rained steady for 11 hours and I could still see the copper on my cherry tree. I was sold. Studies have shown that pinene has anti-fungal properties too. Many essential oils have these properties and I’m going to experiment with some. Like Eucalyptus appears to kill white flies, man they are annoying! I want to try it on the SWD flies also. Most oils are used to repel but Eucalyptus actually kills. I’m going to try it first on fungus gnats, white fly, then SWD if all goes well. I see the pests in that order. I have some fungus gnats now! Looking for something I can use inside with just a spray bottle that doesn’t smell like a chemical factory. See how it works, most reports I have seen say it works very well. Worth trying for me. I can’t suggest it, never tried it.
