How Much Does Tree Pest Control Cost in California?

Tree pests are becoming a growing concern for homeowners across California, especially with hotter seasons and changing weather patterns. If you’ve noticed damaged leaves, holes in bark, or declining tree health, you may already be thinking about professional treatment— and one of the first questions that comes to mind is: How much does tree pest control cost in California?

In most cases, tree pest control typically ranges from $150 to $1,200, depending on factors like the type of pest, infestation severity, treatment method, and the size or number of trees affected. Minor issues may only require a simple spray treatment, while severe infestations from pests like borers or spider mites may need repeat visits or specialized solutions. Understanding what influences the cost can help you budget wisely and ensure your trees get the right care before the damage becomes irreversible.

1. Common Tree Pests in California

a) Bark Beetles

Bark beetles are among the most destructive pests in California, infesting pine, spruce, and cedar trees. These tiny insects burrow into the bark, disrupting the flow of water and nutrients.
Signs of infestation:

• Small holes in the bark.
• Sawdust-like frass at the base of the tree.
• Fading or browning needles.
  If left untreated, bark beetles can kill a mature tree within months. Professional tree pest control is essential for early detection and removal.

b) Wood Borers

Wood borers, such as longhorn beetles and flathead borers, attack weakened or freshly pruned trees. Their larvae tunnel through trunks and branches, compromising the tree’s structure.
Common symptoms:

• Tunnels or exit holes on trunks.
• Sawdust near the base or in branch crotches.
• Dead limbs and peeling bark.

At Tree Doctor, we use targeted insecticide injections and pruning to eliminate borers and protect your trees from further damage.

c) Aphids and Scales

Aphids and scale insects feed on sap, weakening the tree and causing leaf yellowing, sticky residue (honeydew), and fungal growth.
Affected trees: Maples, oaks, and ornamental trees.
Treatment: Horticultural oils, systemic insecticides, and biological control methods can manage these pests effectively. Our tree services ensure your trees stay pest-free and healthy year-round.

d) Whiteflies and Spider Mites

Both whiteflies and spider mites thrive in California’s dry, warm climate. They feed on the underside of leaves, causing discoloration and premature leaf drop.
Warning signs:

• Tiny white or red dots on leaves.
• Webbing or sticky residue.
• Thinning canopy.
  Regular inspections and pest control treatments can prevent widespread infestations.

e) Shot Hole Borers

Shot hole borers are invasive pests that affect avocado, sycamore, and oak trees. They introduce harmful fungi into the tree’s vascular system, leading to branch dieback.
Indicators:

• Small, round holes in the bark.
• Dark staining or sap flow around entry points.
• Sudden branch death.

Immediate professional attention is crucial to stop the spread to nearby trees.

2. Causes and Conditions That Attract Tree Pests

Several environmental and human factors make trees more susceptible to pest infestations:

• Drought stress weakens natural defenses.
• Improper pruning creates entry points for insects.
• Overcrowded planting limits air circulation.
• Neglected maintenance encourages pest breeding.

Routine tree pruning services help identify these risks early and maintain a healthy growing environment.
