The Wildlife Control business is a new industry and companies vary widely in expertise and professionalism.  To be sure you find a company that suits your needs you should follow these guidelines:

• Is the person licensed by the state and insured against any incidental damage that might occur
• Does the person appear knowledgeable and take the time to explain no only what the source of the problem is but also its causes and potential solutions.
• Does the person try to scare you with talk about wildlife diseases or dangerous animals, or do they simply make you aware that you need to be cautious when dealing with wildlife to avoid the risk of infection.
• Does the person offer a written contract?  This is a must!

Just because a company charges a lot of money for its services doesn't necessarily mean that it is better or more reputable than other companies.  Be wary of a company that requires all the money up front.  Any reputable company should be satisfied with 50 percent down and the remaining amount due upon completion of the job.
