Aphids are small, soft-bodied insects that feed on the sap of trees. They cause tree leaves to curl, turn yellow or brown, and drop prematurely. Sticky honeydew secreted by aphids may attract other pests or fungi, resulting in black sooty mold growth on leaves or branches. Infested trees may also show stunted growth or weakened branches. Some aphids on plants can transmit plant viruses, further damaging trees. Timely treatment with insecticides can prevent severe damage.
Spotted Lanternfly is an invasive insect species that attacks trees and crops. The infestation can be identified by several symptoms. The trees affected show weeping wounds, oozing sap, and a black sooty mold. The infested tree’s trunk, branches, and leaves are covered with a sticky residue that attracts ants, wasps, and bees. Severe infestations weaken the tree, and the leaves turn brown, curl up, and drop prematurely. Prevention and early detection are critical in controlling the spread of the Spotted Lanternfly damage. Our Arborist can help reduce the spread of this invasive species and protect the health of our trees.
