Leaf miner

Leaf miners are the larvae of various insects that live and feed inside the leaf tissue of plants. The adult form is a small fly, typically black or gray, only a few millimeters long. The larvae are pale yellow or green maggots that create distinctive tunnels within the leaves.

The most obvious sign is the presence of winding, whitish or tan tunnels visible on the surface of leaves. These tunnels increase in size as the larvae grow. In severe infestations, leaves may turn yellow, brown, and drop prematurely, weakening the plant.

MBPC offers targeted treatments for leaf miner infestations in the Myrtle Beach area, focusing on controlling the larval stage. Our SC Department of Pesticide Regulation licensed technicians can apply systemic insecticides or introduce beneficial nematodes. We also recommend cultural practices like removing infested leaves to prevent further spread.

Inspect plants regularly for signs of leaf miner activity, especially during the growing season in Myrtle Beach. Remove and destroy infested leaves promptly. Encourage beneficial insects like parasitic wasps in your garden to help control leaf miner populations in coastal SC gardens.

Leaf miners are prevalent in the humid subtropical climate of Myrtle Beach, infesting a wide range of plants. They thrive in gardens, greenhouses, and landscapes, particularly on vegetables like tomatoes, peppers, and squash. They can also be found on ornamental plants along the Grand Strand.
