Hi All,

I'm not sosure about how "safe"... see the study below.

We have known that using systemic insecticides
won't help with spider mites.
But did you know it can increase them?

Be careful with BATS (Bayer advanced tree and shrub for any not knowingalready.)

Treatingwith this product can also have a stunting effect on some plants, but

I haven'tfound a study for it. -- Yet.

You can’t go safer than imidacloprid, marketed under names such asPronto. Google it. Your garden centre should have. It issystemic, absorbed through leaf surfaces. They have yet to determine the lethaldose for a rat, I understand, and plants tolerate it very well. It controlssucking insects for a month, so that when eggs hatch, the larvae will feed anddie also.
