Answer: The answer to your question really depends on exactly which insect you are having trouble with. Once you know that for sure you can determine what will control it and then decide what to use based on what is safe for the plants you are growing. You might want to take a sample to your County Extension (347-8650) for a specific identification of the pest and suggestions on ways to control it safely. Since insect populations can build up rapidly in the greenhouse you should probably consult with them promptly. I'm sorry I can't be more helpful.
