Bifen IT is labeled for Orchid Weevils and should do a great job for you. It is always recommended that you spray only one plant to test for any sensitivity/damage before you do a complete treatment on all of the orchids. We also recommend that you speak to an expert that deals with orchids to learn more about treating weevils on orchids as orchids can be very sensitive.
