In general, mites on ornamental plants cannot be treated using systemic insecticides. Bonide Systemic Insect Control contains the active ingredient acephate, so it is labeled for two-spotted spider mites only when applied as a topical spray. Per the product label: Spray when insects are present or when feeding injury is first noticed. For hard to kill insects, such as flower thrips, gladiolus thrips, mealybugs, scales, two-spotted spider mites, and whiteflies, spray 2 to 3 times, waiting 7 to 10 days between each application. Repeat if re-infestation occurs. You can browse other products for spider mites here. To avoid mite resistance, you should rotate between at least 2 products with different modes of action if you need to treat more than 2-3 times in a row.
