Ladybugs - Introduction Rates

Use the chart below as your starting guide. Adjust based on your specific pest species, plant type, growing environment, and infestation level. Multiple releases spaced throughout the growing season consistently outperform a single large release. 

INFESTATION LEVEL	RATE FREQUENCY
Preventative/Light	1 ladybug per sq. ft., monthly
Moderate	1 ladybug per sq. ft., bi-weekly, 2-3 times
Heavy	1 ladybug per sq. ft, weekly, 2-4 times

 

Operating Temperature: Ladybugs are most active and feed most aggressively between 62°F–88°F. They slow below 55°F and will not fly in cold conditions. 

These rates are general guidelines. Closely monitor your plants for 7–14 days after each release and adjust frequency or quantity based on level of pest infestation and observed ladybug activity. If pest populations are not declining, consider combining with Green Lacewings for broader coverage.
