Insects and animals

Most insects who cross our paths are not pests. They serve useful roles including managing populations of pest insects. Through routine observations you will become familiar with insects living around your lawn. Do not consider an insect a pest until the number of individuals reaches a number that threatens the quality of your lawn.  More on beneficial insects.

If you then choose to treat, follow all directions on label and apply the treatment when the pest is most vulnerable. You waste time and money when a pest is not correctly identified or the product is applied at the wrong time of year.
