Pest identification and management strategies
Accurate pest identification is the first step in effective pest control and management. CSU Extension offers research-backed guides, resources, and tools to help you identify pests, understand their behaviors and impact, and implement safe and responsible pest management strategies.
CSU Extension’s resources can help you learn how to support pollinators, distinguish beneficial insects from damaging species, and manage pests in the home and garden, or in orchards, fields, and crops.
