How often should a sprayer be cleaned after use?

1. Every 2 days

2. Every 7 days

3. Each time after use

4. Weekly

The correct answer is: Each time after use

Cleaning a sprayer each time after use is crucial in pest control to ensure the equipment remains effective and safe for future applications. Residual chemicals left in the sprayer can degrade the equipment, clog the nozzles, and lead to cross-contamination of products, which can harm the target pests or the environment. Regular cleaning helps maintain the integrity of the sprayer and prolongs its lifespan. It also ensures that any chemicals used don’t mix inappropriately with residual products, which can create harmful mixtures or reduce the efficacy of pest control measures. By developing the habit of cleaning the sprayer thoroughly after each use, applicators are promoting best practices in pest management and safety.
