Kill Pests to Help Create a Lush Lawn
April 10, 2026
A once-healthy lawn may lose its dense, lush appearance over time, or perhaps it never had that fullness to begin with. Maintaining a hardy lawn is key to surviving attacks from weeds, insects, and diseases.
Understanding Pesticides
The term pesticides refers to insecticides, herbicides, and fungicides designed to control unwanted weeds, insects, fungi, and other lawn diseases. Pesticides can be either synthetic or organic and are applied only when a pest—be it a weed, insect, or disease—reaches a level that threatens the health of your lawn.
Early Detection is Key
“It’s usually a good idea to examine your lawn closely to catch potential pest problems before they become difficult to manage,” says Parwinder Grewal, Ph.D., Associate Professor of Entomology, Nematology, and Environmental Science at Ohio State University. “For example, it’s too late for grub control when skunks are already digging up your turf searching for fully developed larvae.”
Steps for Effective Pest Management
Identify the Pest: Determine the pest species and the conditions that led to the infestation.
Assess Damage Threshold: Only treat when the pest population reaches a level that could cause significant damage.
Use Pesticides Responsibly:
Always read and follow label directions.
Avoid applying pesticides on windy days to prevent drift.
Spot-treat infestations whenever possible.
Keep pesticides away from water sources and impermeable surfaces.
Stay out of treated areas until the product has dried or as directed.
Remember, not all insects are harmful—less than 5% of insects are true pests. Natural predators like birds, bats, toads, and beneficial insects help keep pest populations in check.
Maintaining a Healthy Lawn
A strong, healthy lawn is more resistant to pest attacks than one under stress. Practices such as correcting soil pH, proper fertilization, and regular lawn maintenance help ensure lasting health and beauty.
Homeowners can choose to apply pest control products themselves or hire professionals to ensure safe and effective treatments. In either case, environmental stewardship should be a priority.
“A lawn is the focal point of recreational activity and aesthetic beauty of a property. Regularly analyzing a lawn for pests, weeds, and diseases will help identify problems before serious damage occurs,” says John Gibson, Director of Operations for Swingle Tree, Lawn & Christmas Decor, Denver, CO, and President of the Professional Landcare Network. “Correcting these problems ensures a healthy lawn, saves money on repairs, and enhances the property’s overall appearance.”
