Highly mobile, adult soldier bugs will scurry or fly among plants to discover prey. They suck out their victims’ juices by penetrating it with its large, weapon-like proboscis. Adult female lay barrel-shaped egg clusters colored gray, cream or gold on stems and leaves, each cluster containing 20 to 30 eggs. Female will lay up to 1,000 eggs during their lifespan. Nymphs, which are predacious in four of their five stages, stay close to their egg clusters until they begin seeking prey of their own. Females can live five to eight weeks depending on conditions, males slightly longer. Because the spined soldier bug preys on nearly 100 different pests, it’s highly effective in both gardens and greenhouses.


  • Use 1-2 predators per square foot depending on pest infestation.
  • Dispense eggs evenly over plant leaves and as close to the pest problem as possible.
  • Do NOT release during the sunny part of the day, but rather wait until evening or early morning.
  • Eggs will hatch shortly after release and young nymphs will move quickly from plant to plant in search of food.

Note: P. maculiventris adults are highly mobile, and will spread rapidly throughout the release area by walking and flying.
