Unfortunately, Delta Dust insecticide is considered a restricted use product in NY. You can purchase it legally in NJ. It is not an inherently dangerous product, and is actually very effective, waterproof, and lasts several months if left in a dry area. As far as having to have a license? If you do it for yourself, in your own home, then no, in NJ. In NY, it would be illegal to purchase.
