Gardens & Landscapes, Pest Management In and Around Structures April 18, 2012 Print Friendly and PDF

A pesticide's half-life (also known as degradation) is the time it takes for half of the initial amount of a pesticide to breakdown. If a pesticide's half-life is 30 days, then half will be degraded in 30 days, one quarter in 60 days, one-eighth after 90 days, etc.
