Look Closely and Keep Records

Pay attention to areas or plants where you think there may be a pest problem. Is the pest growing in numbers or doing any real damage? Sometimes, just because an insect is eating a plant, doesn't mean it's really a pest problem. Can you see damage to the plant from ten feet away? Is most of the plant still healthy and nice to look at? Or are all the leaves chewed up with holes that make it look like Swiss cheese? Keep records of what you see and what actions you've decided to take.
