PRODUCT DESCRIPTION

SHIPPED FRESH & QUALITY GUARANTEED

Mealybug destroyer. Attracted to and often lay eggs on the mealybugs' waxy secretions and egg cases.

Cryptolaemus montrouzieri is a member of the Coccinellid Beetle family, commonly known as ladybugs, and recognized by their distinctive round, dome shape. These Mealybug Destroyers have a dark brown body with orange head and tail, and are about 4mm in size. Both the adults and larvae target Mealybugs at all life stages. Eggs are laid near colonies of mealybugs and hatch within 5-7 days. The young larvae emerge as small, white, and fuzzy - resembling mealybugs. After 14-20 days and undergoing several molts, the larvae enter the pupal stage and emerge as adults with a lifespan of 4-6 weeks. Both adult beetles and larvae continue to feed on mealybugs until temperatures become unfavorable. Cryptolaemus montrouzieri cannot endure sub-freezing temperatures, and it’s necessary to reintroduce them after low or freezing temperatures.

INTRODUCTION RATES

Light infestation: 1-2 beetles per sq. ft., as needed.
Heavy infestation: 2-4 beetles per sq. ft.
Temperature Range: 60-95°F

It's important to note that these introduction rates serve as general guidelines and can differ depending on the specific pest species, the plant being treated, and level of infestation. Proper monitoring of the infestation and the released beneficial insect population is crucial for determining the success of the biological control strategy.
APPLICATION

    Introduce in the morning, evening, or when temperatures are cooler.

    Disperse beetles onto infested plants. Leave open container in place for 24 hours to allow any remaining beetles to be introduced.

      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.
      • 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.

      STORAGE

      For best results, introduce immediately upon receipt. If storage is necessary, store at 50-56°F for no longer than 18 hours. Store out of direct sunlight. Do not freeze.
