Pest Identification
Accurate identification of pest species, life stages, and biology - the foundation of all effective pest management decisions.
Detailed Overview
Proper pest ID is critical because treatment methods vary dramatically by species. German cockroaches require gel baits in kitchens; American roaches need perimeter treatments and moisture control. Norway rats burrow and need ground-level bait stations; roof rats climb and need elevated stations. Subterranean termites require soil treatments; drywood termites need fumigation or localized wood treatments. Misidentification leads to wrong product selection, wasted time, and treatment failure. PCOs must recognize species by sight, identify life stages (egg, nymph, adult), understand behavior patterns (nocturnal vs diurnal, feeding preferences, harborage), and know biology (reproduction rates, development time, overwintering). Use field guides, trap catches, and customer descriptions. When uncertain, collect specimens for lab identification. Species-level ID determines everything: product choice, application method, timing, frequency, and expected results.
When to Use
Always identify pest species before recommending or implementing treatment. Re-verify ID if treatments are not working as expected. Collect specimens when visual ID uncertain.

Integrated Pest Management (IPM)
A prevention-based pest management method that provides long-lasting pest control, improves building conditions, and is less harmful to residents and pets than traditional pest control.
Pest Triangle
The four essential requirements pests need to survive: food, water, shelter, and ways to get around. Eliminating any of these makes an environment inhospitable to pests.
Threshold Levels
The point at which pest populations or damage reaches a level that requires action. IPM uses threshold levels to determine when treatment is necessary rather than treating on a schedule.
