Why does time of application matter?

• A. Pesticides must be lethal when insects are active.
• B. It should be applied during rainy conditions.
• C. It should be applied only at night.
• D. It should be applied before sunrise.

Answer: (A)

Pesticides work best when pests are exposed to them at lethal levels, which happens when insects are active and feeding. If you spray when pests are hiding or inactive, they’re less likely to contact or ingest enough of the product, so control is poor and you may need to reapply. In ornamental and turf settings, aligning application with when pests are actively feeding maximizes exposure and effectiveness. Weather and environmental factors also play a role—rain can wash off a spray and high or low temperatures can affect how well a product works—so timing helps ensure the product does its job under favorable conditions. The specific clock time (night, before sunrise, etc.) isn’t the main driver of effectiveness; it's the pests being active and the conditions being suitable that matter.
