Pyrethrum and permethrin are always a mistake. The idea that they "come from crysanthemums" as many of the labels state doesn't make them any less toxic - they are now synthetic and stronger and are a neurotoxin. In early days it was thought they were organic - but those days are long gone. If you need to use something like that just get rid of the plants and start over. Seriously.

Orange oil (delimonene) in water at 2 ounces per gallon will kill the bugs in the garden or on these plants. Spray from a pump sprayer. Add a little compost tea or molasses and you can make it a foliar feeding at the same time.
