Answer: Modern recommendations with regard to spraying for insects indicate that there is no need to spray unless there is damage that threatens the health of the plant. Since there is no damage at all, there is nothing you need to be spraying at this time.
If you do ever seen an insect problem developing, first you would need to identify the specific insect and then once you know that, determine the potential damage level it will probably cause. If the damage becomes or threatens to become severe, then you would resort to control measures.
Which spray to use would be based on which specific pest you are trying to control. Your local county extension should be able to identify any pest for you and suggest how to control it. If a spray is needed, they will have the most up to date recommendations for what to use in New York state and how/when is best to apply it.
You would also of course carefully follow the label directions on any product you use. Further clarification of hte label instructions may be obtained from the manufacturer, if you need it.
I hope this answers your question.
