Learn about Northern California’s most common tree pests below.

1. Aphids and Scale Insects
Aphids and scale insects are small but destructive. Both often go unnoticed until they do enough damage to cause the tree’s leaves to start curling or turn yellow. These pests feed on the sap in the leaves or inner bark, eventually weakening the tree or leaving it vulnerable to other tree diseases.
You can often find aphid and scale insect infestations by turning over the leaves. They leave behind a sticky residue (honeydew) that attracts sooty mold (a black film).
2. Bark Beetles
Bark beetles are common tree pests in conifers or oaks. These tiny beetles bore into tree bark, spreading disease and fungal spores between trees. Eventually, this infection can damage or kill your tree.
Look for boring dust and sap-like blobs on the outer bark. You might also see reddish-brown foliage running downward from the top of the tree.
3. Spider Mites
Eight-legged spider mites typically emerge in force in the summer heat, bringing widespread destruction. Since these tree pests feed on chlorophyll, seeing white spots, yellow speckles, and discoloration signals infestation. You might also notice fine webbing on the undersides of leaves.
A strong blast of water might help control a minor problem. Heavier mite damage calls for more targeted tree pest control methods.
4. Defoliators
Destructive caterpillars form silky webs in tree crotches, especially in fruit and shade trees. For example, Western tent, gypsy moth, and spongy moth larvae are common tree pests in Garberville.
The caterpillars live together in the nests and feed on the tree, expanding outward throughout the season. Eventually, they eat every leaf on the tree. Hand removal or pruning the affected branches as soon as the nest forms will usually stop the insect infestation.
5. Wood Borers
Wood borers, like the emerald ash borer and Asian longhorn beetle, drill into tree trunks and limbs, slowly hollowing them out. You might not notice these pests until it’s too late. However, you can look for exit holes, sawdust at the base, or dieback in certain branches as early signs of boring insects.
Because borers attack from the inside, these pests require professional treatment.
