Why is identification important?

Whether your pest is a weed, insect, animal, microbe, or other organism, correct identification of your pest makes controlling it easier and often more effective. A mistake in identification can lead to improper control tactics that cost time and money. It may also lead to unnecessary risks to people or the environment.
