Aphids!

[camille1585]

Aphids don't really need something as strong as imidacloprid. The downside of this chemical is that it will damage blooms.
Watch out with the alcohol. I have used it with some success against mealies, but if you spray mounted plants you really need to avoid the roots. I sprayed the roots of a plant and that ended up killing the roots, and then the plant died...

Whatever you spray with, you should repeat it few times every few days because aphids multiply like crazy! Adults put out 4-5 nymphs a day, and the babies are adults within 10 days.
