Only way I know to keep aphids out of the greenhouse is to use only clean pots and sterilized potting soil. I tried overwintering pots that had been outside for a while...big mistake! Oddly enough, I almost never see aphids outdoors, but let me bring an outdoor plant inside and the little beggars come crawling out of the woodwork! Every time.

If you take a hose inside your greenhouse, and gently spray down the plants, maybe once a week, that can wash off a lot of aphids. It will also humidify the air for you, which is probably a good thing where you are?

A mild soapy water solution, about 1/2tsp. of dish soap to a quart of water in a spray bottle is also a good preventive measure. If you spray that on the whole plant (be sure to get the undersides of the leaves as well as the tops) on a regular basis, it will kill most sucking insects like aphids, whiteflies and spider mites.
