Cryptolaemus montrouzieri - Pro Tips

Attracted to and often lay eggs on the mealybugs' waxy secretions and egg cases.
For best results, introduce in early spring. Cryptolaemus montrouzieri cannot survive in cold temperatures (below 50°F), and therefor need to be reintroduced where the winter temperatures are too low.

Packaging contains paper strips for shipment as well as honey for food source.
Cryptolaemus are not as effective on mealybugs that do not lay egg masses, such as long-tailed mealybugs.
Treat area against ants. Ants tend to mealybugs and some scale insects for honeydew, and in the process protect the pests from the beneficial insect.
Pesticides, even-wetting agents, and spreader-stickers may adversely affect beneficial insect survival. Broad spectrum and systemic insecticides are toxic.
Depending on the size and type of plants, the number and type of pests, other predator and parasite populations, and temperature, the frequency of releases may be affected.
