Biology

Stink bugs are shield-shaped and range from ¼ to 1 inch in size and usually discharge a disagreeable odor when handled. Although plant-feeding stink bugs are more common, a number of species of predatory stink bugs may be found in gardens including the cryptically colored rough stink bug.

Like many predatory bugs, the rough stink bug may feed occasionally on plants but does not cause noticeable damage or injury. Until recently, the Pacific Northwest was fortunate in not having any stink bug species capable of causing serious damage to plants or crops.

The invasion of our area by the marmorated Asian stink bug (Halyamorpha halys), which is very similar in appearance to the rough stink bug, has changed this. Identification should be sought for any stink bug found in the garden before encouraging its persistence.

• 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.
