I would contact a pest control business in your area, see if you can observe or help in the shop.this will give you an idea if its something you want to persue. dont try it without any training !! you can hurt yourself and it wouldnt be fair to your customers. being a PCO is a great job but like any business you only get out of it what you put in it.Ive been a PCO for 15 years i have my own business and i really enjoy it. But it didnt happen over night GOOD LUCK!!
