Сurt,

We used that a few years back. It works on direct contact.

But it also kills many beneficial insects, so we stopped using it.

Now our garden is filled with many beneficials - lacewing, parasitic wasps, aphidoletes, hoveflies. They take care of aphids and mites and other bad insects.

I will never spray anything, even organic, again. I want my beneficial insects to reproduce in the garden and take care of the pests. It seems to work very well this year, but be warned that if you want to go this way, it may take an year or two to restore the natural balance, and pests can be abundant in the first year.

Good luck!

Tatiana
