It is rather difficult to target pests like moths and caterpillars specifically, because most pesticides will also harm beneficial insects (like bees). However, since crops like cabbages don’t need to be pollinated, you have more options. We would recommend using a natural pesticide, like Bacillus thuringiensis (Bt) or Neem Oil, but if those are not available, a synthetic pesticide containing permethrin could be used.
