Most Common Evergreen Plant Pests:
Identification and Treatment Guide

Evergreen plants are a beloved addition to many gardens and landscapes. However, they are not immune to pests. In fact, there are several insects and diseases that can damage or even kill evergreens if left untreated. In this article, we will go over the most common evergreen plant pests, how to identify them, and the best treatments to keep your plants healthy and thriving.

Spider Mites

Spider mites are tiny pests that are often found on the undersides of evergreen leaves. They cause damage by piercing the cells of the plant and sucking out the sap. This can result in yellowing or browning of the leaves, as well as stunted growth.

Identification

Spider mites are difficult to see with the naked eye, but you may notice fine webbing on the undersides of leaves. You may also see small, yellow or brown spots on the leaves.

Treatment

The best way to treat spider mites is to spray your plants with a strong stream of water to knock them off the leaves. You can also use insecticidal soap or neem oil to kill them.

Scale Insects

Scale insects are another common pest that can affect evergreens. They are often found on the stems or branches of plants and feed on sap. Over time, this can weaken the plant and cause it to die.

Identification

Scale insects look like small bumps on the stems or branches of plants. They can range in color from white to brown or black.

Treatment

The best way to treat scale insects is to scrape them off with a soft-bristled brush or cloth. You can also use insecticidal soap or neem oil to kill them.

Bagworms

Bagworms are caterpillars that spin a cocoon out of silk and pieces of plant material. They then attach the cocoon to the branches of evergreens and feed on the leaves. If left untreated, bagworms can defoliate a plant and cause it to die.

Identification

Bagworms are often mistaken for pine cones or other plant material. They are attached to the branches of evergreens and can be difficult to spot.

Treatment

The best way to treat bagworms is to handpick them off the plant and destroy them. You can also use insecticidal soap or neem oil to kill them.
