Please dont put mothballs on your plants. If you do tell me ahead of time so I dont smoke it. Mothballs have chemical pesticides in them (and not the ones meant for food) You will likely make someone sick AND probably poison a ton of birds making your grow very obvious when birds start dropping dead in all the yards in your neighborhood. Also mothballs smell bad.

If you want to keep the birds off of your plants go with the netting (small holes so you dont ensnare any local birds.
