Preventing Asian Citrus Psysllid (lemmy.world)

I have a small lemon tree that was bought from a local grower and came with the extra bonus of an Asian Citrus Psysllid infestation. The tree is dead now and I'd love to get a new tree, but want to make sure I've done everything I could to prevent a new tree from getting infested by any Psysllid still in the area.

Is there anything I can do to treat my soil or surrounding plants to make sure those little buggers aren't going to keep coming back? I'm in California where the sale of IMIDACLOPRID products is banned, which was previously the primary treatment for this.

Diatomaceous earth maybe?

Since generalist predators control them planting a pollinator/predator flower blend is recommended. These are nectar producing species in a collection that blooms all year long.

This will attract and give habitat for the generalist predators. It works pretty well. Since I turned my front flowerbed into one I almost never seen aphids on my roses anymore.
