Depends on the pesticides, you’d have to read how that particular pesticide works. But in general, pesticides that claim they only need one application every few months have a long residual.

The chemical remains on the surface, and either acts as a repellent, or makes the chemical will stick to the bug as it walks over it and it will die.

Many chemical compounds are long-term stable, even outdoors. Unless the area is thoroughly washed they will persist and keep killing insects for a long time.
