Why is IPM better than relying solely on chemical control?

The core reason IPM is superior to purely chemical control is that it addresses the root cause of the problem, not just the symptoms.

Chemical control only kills visible pests, but without sealing entry points, cutting off food and water, and eliminating hiding places, new pests will continuously pour in — creating a vicious cycle of "spray — re-infestation — spray again.

" IPM breaks this cycle from four directions: Prevention (permanent exclusion and sanitation) provides effects far longer than a chemical spray (which degrades after a few weeks).

Monitoring data provides an objective basis for decision-making, rather than spraying based on a gut feeling.

Choosing the least-risk method reduces impacts on the environment and human health.

The evaluation step ensures continuous improvement of the methods.

Research consistently shows that households adopting IPM can reduce insecticide use by an average of 50–90% without sacrificing pest control effectiveness.
