Maybe, what shall I do? I’ve heard that spraying soap and vinegar may help.
I would try the cheapest, easiest, and fastest method first, and progress to more expensive, etc., when something proves not effective. You could jump right to Most expensive and hardest to apply, but I wouldn't.
Cheap, easy, and you can do right now is turn the hose on it and hit under the leaves for a long time. That will knock everything off. If they come back tomorrow, proceed to something harder.
