Life Cycle Targeting
Timing treatments to target vulnerable life stages for maximum control efficiency and population suppression.
Detailed Overview
Every pest has vulnerable points in its life cycle where treatment is most effective. Mosquito larvicides target aquatic larvae before they become biting adults. Flea IGRs prevent eggs and larvae from developing into biting adults. Termite baits target foraging workers during active season. Grub preventatives applied in late summer kill newly-hatched larvae before they damage turf. Understanding development times helps predict when populations will peak: bed bug eggs hatch in 6-10 days requiring follow-up treatments; roach nymphs develop over 6-12 months providing long treatment window; fly eggs to adults in 7-10 days requiring rapid intervention. Some life stages are pesticide-resistant: roach and bed bug eggs have impermeable shells requiring residual products to kill emerging nymphs; flea pupae in cocoons are protected requiring extended monitoring. Hitting pests at vulnerable stages prevents reproduction, reduces populations faster, and requires less product than treating only adults.
When to Use
Plan treatment timing based on pest development cycle. For seasonal pests, treat during vulnerable stages before populations peak. Schedule follow-up treatments timed to pest development rates.

Limitations
- Requires knowledge of pest biology and development rates
- Weather and temperature affect development timing
- May require multiple treatments timed to life cycle

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.
