Professional exterminating provides faster and more effective results than do-it-yourself methods, in most cases. They can also save you money in the future by identifying pest problems early and eliminating them fast, preventing a costly infestation and/or damage in the future. For a small infestation, do it yourself is a good option that can be inexpensive. For larger infestations or a continuing problem, save yourself the time, hassle, and money and call a professional exterminator. As always, the key to pest control is prevention.
