It not only attacks insect eggs, but larvae such as caterpillars.

The citrus leaf miner, a few varieties of mites and other insect pests can be difficult to purge because the tiny eggs are laid inside the leaf structure. Topical pesticides really don't have much effect. Systemics like Isotox work well, but can't be used on edibles. But to the Spinosaid bacteria, the leaf structure is more like a trellis which is penetrated with ease. I use it once per month for 6 months starting in March or April. However, it is not enough. I also spray once per month staggered 2 week later with a pyrethrin.
