Praying Mantis solves this NP. They hatch in late July but mature and feed at the end of August when buds are blooming. We've had them established in our yard for 15 years plus. Very cool looking but also killers when it comes to plant parasites. You can buy them but it wouldn't help until next year. I have seen at least 5 sitting on my plants at any one time ready to eat anything that dares to touch my babies. You also don't have to flush after spraying lol.
