get you some from the hardware store. spray the whole plant, and make sure you get underneath too, this stuff is biodegradable and safe, it might take a few sprayings to get rid of them, but once they are gone, us a fine spray of ph balanced water to rinse them. that should get rid of them, but keep a close eye on them for reinfestation. you also can use a little dish soap and water to do this, but i would not recomend to a novice and also it`s hard to say which soap because of all the chems in all the different brands
insecticidal soap is the safest way i know other than picking and scraping the plant by hand.
good luck
