Bird droppings

I got a question as to the best product to use to clean up bird droppings from pigeons that were roosting for years in an attic type crawl area of a home. My answer was quick. No product is good for you to use. Notice I used the word, "you". This is a case where you call a professional and have them clean this area up. If you were to go up there with a shop vac or broom and start sweeping up those droppings and the dry droppings became airborne you would have the potential to catch some very nasty and potentially fatal diseases. Bird droppings and bat droppings are nothing to fool around with by people who don't know what they are doing. While I'm on the topic, neither are mouse droppings. If you ever come across a mass amount of droppings in an attic or crawl space or anywhere, you need to call a pro. They have the proper equipment and chemicals and knowledge to do the job safely and efficiently. That's why bird work is such a specialty business.
