Keep in mind that there is good scientific evidence that systemic insecticides like Imidacloprid can harm your pollinators, bees.

You might try Spinosad. It seems to work for citrus leafminers in my yard, and if you apply it in the evening (and especially if you work to avoid the flowers), probably has little if any effect on bees.
