A. Using the finest spray possible
B. Spraying in high winds
, C. Using coarse droplets and low pressure when appropriate
D. Spraying from maximum height
Coarser droplets and lower pressures reduce fine mist formation and drift potential.
12. Pesticides should be stored:
A. In a busy hallway for quick access
B. In a locked, well-ventilated area, away from food and feed
C. Next to cleaning products in the kitchen
D. In a vehicle parked outside
Secure, locked, ventilated storage away from food/feed reduces risk of accidental exposure

A. Indoor Pesticide Method
B. Integrated Pest Management
