Common Northern California Tree Pests and Diseases
Several pests and diseases are currently infecting and killing trees in Northern California. Catching these common tree maladies early will help preserve your trees and keep them healthy.
- Sudden Oak Death: Sudden Oak Death has devastated forests in Northern California and kills thousands of oak trees each year. It is important to take preventative measures to stop Sudden Oak Death before it infects and kills your tress.
- Tussock (Gypsy) Moths: The Tussock moths are one of the most invasive species. Their nests will cause the tree to lose leaves or needles. While they do not kill trees, these moths will stress trees, leaving them susceptible to other pests and diseases.
- Pine Pitch Canker: Pine Pitch Canker is a fungal disease that spreads rapidly from boring insects like bark beetles, carrying the disease from one tree to another. Infected trees will have sunken trunk cankers that ooze yellowish resin.
- Bark Beetles: These small beetles will bore into trees and produce a fungus that interrupts the tree’s circulatory system and can rapidly kill the tree. They can also spread diseases like pine pitch canker from one tree to another. A healthy tree can defend itself from these pests, but a weakened tree due to drought or other environmental factors is susceptible to bark beetles.
- Deer: Deer are one of the largest tree pests; they are known to eat new growth on your trees and plants, stunting their growth or killing them. To keep deer away, consider adding netting or a tall fence around your trees and plants — or get help from a professional.

Tree Pest and Disease Control FAQs
If left untreated, an infected tree can rapidly spread pests or diseases to surrounding trees or plants. Infected trees should be treated or removed to prevent spread. Surrounding trees should be inspected for overall health and signs of pests or disease to ensure they are not infected
- Displacement of Native Plants: Invasive species lack natural predators or competition, growing uncontrollably and outcompeting native plants, leading to the decline of important local species.
- Impact on Pollinators and Wildlife: Native plants support local ecosystems by providing vital nutrients, shelter, and resources for the local fauna. Invasive species disrupt this balance, affecting wildlife and local environment.
- Soil Degradation and Water Flow Alteration: Invasive plants change nutrient cycles and soil structure with their root systems. As a result, they can lead to disruption of water and nutrient movement, increased runoff, and erosion, which prevents local species from thriving.
Trees that are stressed, damaged, or lacking proper nutrients cannot fight off diseases or pests. Ensuring your trees are healthy and receiving the right amount of sun, water, and fertilizer and are healing correctly after damage is the most important step in pest and disease management.
Yes, left untreated pests such as bark beetles and diseases such as Sudden Oak Death are known to kill trees in Northern California. Taking proactive preventative measures to stop pests and disease and treating infections early will help keep your tree healthy and standing tall for many years to come.
