aphid control

An overview of pests of houseplants, nonchemical control, and pesticides is
at:

With a few more photos and a timely revision, the site would be top-notch.

Imidacloprid is not included in the above because it is too new. An assessment
of it is found here:

Reported as having lower human toxicity than Dysyston (Disulfoton), it is
highly effective with Homoptera (e.g., aphids, soft scales, mealybugs,
whiteflies) but useless with spider mites. One formulation is in a potting
soil.

a good collection of spiders doesn't hurt, either
