Protecting Your Lawn, Trees & Landscape All Year Long

Central Pennsylvania’s climate creates changing conditions that can attract pests and diseases throughout the year. Heritage Lawn & Landscape Care provides expert identification and treatment to protect your lawn, trees, and shrubs—before small issues become costly damage.

Common Lawn Pests & Diseases

Grubs

A leading cause of turf damage in late summer and fall. Grubs feed on roots, creating soft, browning areas. Preventative treatments offer the best protection.

Chinch Bugs & Surface-Feeding Insects

Often mistaken for drought stress, these insects damage grass blades during hot, dry weather. Quick treatment helps prevent spreading.

Lawn Diseases

Humidity and seasonal weather patterns can trigger turf diseases such as brown patch, dollar spot, red thread, and snow mold. Timely applications reduce activity and restore healthy growth.

Tree Pests & Diseases

Spotted Lantern Fly (SLF)

A regional invasive pest affecting maples, walnuts, willows, and more. Heritage provides inspection and targeted treatments to reduce activity.

Shrub & Landscape Plant Issues

Bagworms

A common pest on evergreens and ornamental shrubs across Central PA. Early-season control helps prevent significant foliage loss.

Japanese Beetles

These mid-summer feeders skeletonize leaves on roses, lindens, and other ornamentals. Timely treatment reduces damage and protects plant health.
