Science-Driven Stewardship for the Central Coast

Protecting homes, trees, and landscapes through environmentally responsible, research-backed pest and plant health care.

Central Coast of California landscape

Rooted in Science. Driven by Stewardship.

At Williams Pest Management, we believe the best pest control starts with understanding ecosystems, not just eliminating pests. Our founder's journey from punk rock DIY culture to environmental stewardship shaped our commitment to science-based, ecologically responsible solutions. We're not here to wage war on nature—we're here to restore balance.

Protecting California Oaks with CanopyShield™

Oak Canopy Protection

Our proprietary CanopyShield™ program combines biological larval control with foliar phosphite defense to protect your oaks from destructive caterpillars like California oak moth and fall cankerworm. This integrated approach strengthens the tree's vascular system while targeting pests without harming beneficial insects.

  • Safe for pollinators and beneficial insects
  • Stops larval feeding within hours
