Termites, for example, can cause major structural damage. However, large numbers of ants in the lawn rarely do any damage and have little relationship to the number of ants that enter the home. Before applying any pesticide, consider alternative management strategies. Many pest problems can be prevented. Use good horticulture practices, such as proper mowing and fertilizing to keep a lawn thick and healthy to prevent new weeds.
Lawns can tolerate a few grubs.
When lawns reach 8 to 10 grubs per square foot, then damage may be seen. Choose pest resistant plant varieties for the landscape to help prevent insects and diseases. Properly seal and caulk around windows and doorframes to prevent insects from entering the home. Often the use of pesticides is not necessary. If the situation does require the use of a pesticide, be sure to read and follow the label recommendations.
