AsNoriuanswered grow question 4 years ago Few not enough. You can buy natural predators relatively cheap . Search for Orius Laevigatus for sure deal. I met thirps first time this year. More than 50 ladybugs was not enough, bought ladybugs larvae, no obvious improvement, but after Orius, everything sorted out really quick.
I wish i would not wait and knew right answer then. And i wish i never use neem oil.
Good luck !
