How to Manage Pests

Estimate your sprinkler output using the "can test"

Roll your mouse over each step to see it illustrated.

	1. Evenly space six or more straight-sided food containers, such as tuna cans or cat food cans.
	2. Run your sprinklers for 20 minutes.
	3. Measure the water in each can with a ruler.

Calculations

• Average the depths of water by adding up the measurements and dividing by the total number of cans you used.
• Multiply the average by 3 to estimate how many inches of water your sprinkler system puts out in an hour. Round to the nearest half-inch.
• Use this number to help schedule your irrigation.
