Melampodium and Spider Mites

Raleigh, NC(Zone 7a)

Early this year, I planted a lot of verbena. It got a bad case of spider mites, and I had to pull it all out. In its place, I planted melampodium, which seems to have inherited the spider mites. I am spraying with Kelthane, but I don't know how often I should spray. Should it be eevery day for "a while," or once a week, or what? I'll appreciate any advice.

Kelthane is strong stuff. You might want to alternate it with another product because spidermites can become immune to pesticides. I'd spray once a week, and alternate with something else. Maybe Neem oil or something that's not as strong.

Thanks very much. They didn't warn me about that at the garden store. Kelthane is also very expensive, so I will be happy to alternate it with something else. I don't know about Neem oil, but I will see what I can find out.
