Here is what I found on the net... Control of Spider Mites on House Plants Control on house plants can be particularly frustrating. There generally are no biological controls and few effective chemical controls (primarily soaps and horticultural oils). When attempting control, treat all susceptible house plants at the same time. Trim, bag and remove heavily infested leaves and discard severely infested plants. Periodically hose small plants in the sink or shower. Wipe leaves of larger plants with a soft, damp cloth. Reapply these treatments at one- to two-week intervals as long as populations persist. Table 1: Pesticides useful to control spider mites in yards and gardens. Active Ingredient Trade Name(s) Comments acephate Orthene, certain Isotox formulations Insecticide with some effectiveness against spider mites.

Selective miticide that affects developing stages and eggs only. One application per season label restriction. horticultural oils Sunspray, others Used at the "summer oil" rate (2 percent), oils are perhaps the most effective miticide available for home use. insecticidal soap several Marginally effective against twospotted spider mite and where webbing prevents penetration.

I live only about 45 minutes north of you if you are near Baltimore. I live just north of the MD border in Eastern Pa right now.

I once grew parsley and other herbs successfully in a very cold enclosed porch under 48" fluorescent lights supplemented by 4 incandescents. That was years ago. Typically a sunny window doesn't provide enough sun in winter. I have thyme and rosemary in my SW living room window now. The rosemary is ok but the thyme looks light starved and unhappy. I have 2 250 w fluorescents supplementing them, but it is not enough. On top of that it is too warm for them even though I keep the heat around 65.

luv, the plants you have in pots ..have you re-potted them recently or are they potbound in old soil mixture? Plants that have optimum soil conditions will happily grow and tolerate minor attacks from bugs. If your potted plants are being attacked by multiple types of chewing and sucking bugs those plants were stressed to begin with and pesticides may kill the bugs you see but also any beneficials in the potting soil holding the plant. Can you find a spot with filtered light where you can replant these injured plants in the ground where any further treatments are less likely to disturb the soil beneficials. Use captured rain water for watering these plants you've put into the ground. Stake them for support. Once they are healthy again you can lift and repot them in the fall with the soil they are growing in. Expect more roots and need for a larger pot.
