Laws on the removal of nuisance wildlife vary from state to state. Some states require a test for animal damage control operators, and many states require a permit for handling many species of wildlife. The first place to begin is with the department in your state that is concerned with wildlife management. They can guide you through this process. You may also want to speak to others in this line of work.
Before you start this particular type of business, be sure you ask yourself some crucial questions:
* Are you willing to climb on roofs and other high places?
* Can you tolerate working in cramped spaces such as attics and crawlspaces?
* Do you understand the risks of rabies and other zoonotic diseases?
