Release Instructions for Ladybugs:

Once you have made it home with your Ladybugs, put them in a household refrigerator but DO NOT FREEZE THEM. Ideally the live Ladybugs should be released in the evening or very early morning when it is cool or overcast so they move more slowly. Do not release during the heat of the day, as heat causes Ladybugs to become overly active and they are more likely to fly away and find shelter away from the original release site. Prior to releasing, water your plants and leaves. This will hydrate and relax your ladybugs after their journey. Ladybugs should be released a few at a time on all plants, twice a week during the season when your plants are lush and attractive to pests. 

When you buy live Ladybugs from GardeningZone.com they are shipped as adults in containers, pouches, mesh bags and cloth bags. Storing the beetles can be done at a temperature of 40°F to 60°F for 1 - 3 weeks. Ladybugs can begin reproducing immediately with a good source of food and water. Several generations of Ladybugs may occur during one season.

Ladybugs are collected from nature instead of insectaries (it is not cost effective to raise Ladybugs in insectaries due to the amount and cost of food it would take to produce an adult Ladybug). The Ladybugs are refrigerated until sold, for in cold weather Ladybugs will go into a sleep state or dormant state. Some researchers and many users have observed immediate and substantial predation and egg-laying upon release.
