There are quite a few products available that can be used in certified organic production. However, they each have their own quirks and limitations, and no one product is a silver bullet. Soft-bodied flies and worms can be effectively managed with a variety of organic products while hard-bodied insects have the fewest options available and are more difficult to control organically.
DISCLAIMER: always check with your certifier before applying ANY substance to your certified organic land or crops.
