Biology
Ambush bugs are closely related to assassin bugs but are smaller (1/2 inch) and specialize in preying on insects visiting flowers. Hiding within the flowers they kill unsuspecting wasps, flies, bees and butterflies.
Immature ambush bugs, however, live on other parts of the plant and contribute better to garden pest control by feeding on small soft bodied insects and mites.
Batches of eggs cemented together by hardened froth may be found on twigs or fences in the fall and winter.
Prey or Pest Targeted
- Mites, aphids, leafhoppers, thrips, caterpillars, mealybugs, beetles, scale insects, insect eggs
Attracting and Keeping Natural Enemies
and Pollinators in Your Yard and Garden
- Native plants provide essential resources.
- Native flora also provides natural overwintering sites.
- Natural dispersion from nearby habitats ensures visitation.
- Some kinds of beneficial insects predatory mites are commercially available.
- Avoid regular use of synthetic, broad-spectrum pesticides.
- Infrequent use of certain narrow-spectrum pesticides is more compatible with some beneficials.
- Extensive lawns are also not conducive to attracting beneficial insects.
Management Options
See "Using Integrated Pest Management (IPM) in the Landscape" for successful problem management techniques.
