The best places to look will be in lush plant growth (especially if there are aphids). Agricultural fields can make excellent collecting sites. Crops that are known to harbor ladybugs include forage fields like alfalfa, clover, and grains like wheat and corn (before it gets too tall).
During early spring (March and April) they should be used somewhat sooner, as these are older ladybugs from the previous year. During May, ladybugs should be released immediately.
Where can I find a lot of ladybugs?
They seem drawn to homes with natural wood siding, homes in wooded areas, light-colored homes warmed by sunlight, and older homes with lots of cracks and crevices. Ladybugs leave behind trails of pheromones, which attract them to the same sites year after year.
How many ladybugs are needed for pest control?
Classical or inoculative biological control means that ladybugs not already present are released in hopes they will establish a population and can serve as pest control. How many ladybugs do you need? Approximately 2,000 are enough for a small garden with 18,000 probably more than enough for a large garden.
