Why should I hire a pest management professional when I can do it myself? Do-it-yourself pest control is certainly an option, at least for homeowners and some businesses, but most homeowners and business owners lack the scientific knowledge and training needed to treat pest problems effectively. An essential component in treating a pest problem effectively is correctly identifying the insect species and developing a course of treatment that takes the insect's biology and habits into account. It is also critical that the treatment materials used are handled properly to ensure effective treatment. A professional pest control operator has the training and expertise to do these things, leading to the most effective solution to your pest problem.
