Common Tree Pests in Contra Costa County

The East Bay’s mild climate allows many pests to thrive year-round. Evergreen’s arborists are trained to diagnose and treat local infestations, including:
• Bark Beetles – Bore into conifers, causing dieback and canopy thinning.
• Aphids & Scale Insects – Produce sticky residue and attract mold.
• Oak Worms & Tent Caterpillars – Defoliate oaks and deciduous trees in spring.
• Eucalyptus Longhorned Borers – Attack stressed eucalyptus trees.
• Invasive Shot Hole Borer (ISHB) – Spreads fungal disease and kills host trees.
• Sudden Oak Death (SOD) – A pathogen spread by bay laurels, fatal to oaks.

Early detection and treatment are key to protecting tree health and property value.

Our Pest Management Process

We combine science-based diagnosis with targeted, low-impact treatments:

Inspection & Identification – Certified Arborists inspect for insect activity, canopy dieback, and entry holes.
Treatment Planning – We match the pest species to the safest, most effective treatment method.
Professional Application – Treatments may include trunk injections, bark sprays, or soil drenches.
Ongoing Monitoring – We schedule follow-up visits to confirm pest control success and prevent reinfestation.

Treatment Options We Use

Our pest management programs use trusted industry products and techniques that minimize environmental impact while ensuring effectiveness:
• Pointer and Boxer Trunk Injections – Deliver precise control directly into the tree’s vascular system.
• Astro Bark Sprays – Protect bark surfaces against borers and beetles.
• Merit Soil Applications – Long-lasting systemic control for aphids and scale.
• Preventive Programs – Seasonal treatments to stop re-infestation and support long-term health.

When to Schedule Pest Management Services

Many pests become active in spring and summer, but prevention is most effective when started early. Schedule inspections before peak activity—especially for oaks, pines, and sycamores, which are more vulnerable to beetles and borers.
