using imidacloprid indoors on calathea
i have a large calathea that is having a persistent problem with aphids. i have been using insecticidal soap periodically, but it does not go away. in such situations in the past, i have used the systemic granular form of imidacloprid to treat aphids on my houseplants.
does anyone know whether calatheas are particularly sensitive to systemic insecticides like imidacloprid?
thanks in advance. kathy
