Fashionably Bugged: Unveiling the Stink Bug Invasion in Oregon

Are there stink bugs in Oregon?

Stink bugs are a type of insect found in various parts of the United States, including Oregon. These insects belong to the Pentatomidae family and are known for the foul odor they emit when threatened or disturbed. In recent years, stink bugs have become a concern for homeowners and farmers due to their potential damage to crops and annoyance in residential areas. In this article, we will explore the presence of stink bugs in Oregon, their characteristics, potential impacts, and ways to effectively manage their populations.

Stink Bug Identification and Characteristics

Stink bugs, scientifically known as Halyomorpha halys, are medium-sized insects with a distinctive shield-shaped body. They can vary in color, but are usually brown or gray with various markings. Stink bugs have a piercing sucking mouthparts that they use to extract plant juices. They are primarily herbivores and can feed on a wide variety of plants, including fruits, vegetables, and ornamentals.
One of the key characteristics of stink bugs is the pungent odor they emit as a defense mechanism. When threatened or crushed, they release a foul-smelling chemical from special glands on their thorax. This odor acts as a deterrent to predators and can be quite unpleasant to humans.

Stink bugs in Oregon: Distribution and Impacts

Stink bugs have been reported in various regions of Oregon, including both urban and agricultural areas. While their presence has been documented in the state, the severity of infestations can vary from year to year and location to location. Stink bugs are known to overwinter in sheltered areas and may emerge in the spring to feed and reproduce.

In agriculture, stink bugs can pose a significant threat to crops such as hazelnuts, apples, pears, and cherries. Their feeding can cause cosmetic damage to fruits and vegetables, rendering them unmarketable. In addition, stink bugs have the potential to transmit plant diseases, further compromising crop health. In residential areas, stink bugs can become a nuisance as they seek shelter indoors during colder months and often congregate in large numbers.

Stink bug prevention and management

Preventing stink bug infestations and managing existing populations requires a combination of proactive measures and targeted treatments. Here are some strategies that can help homeowners and farmers minimize the impact of stink bugs:

  1. Exclusion: Seal cracks, gaps, and openings in windows, doors, and foundations to prevent stink bugs from entering buildings. Install screens on windows and vents for additional protection.

  2. Sanitation: Remove weeds, fallen fruit, and other debris from around crops or gardens, as these can attract stink bugs and provide shelter.

  3. Physical barriers: Use fine-mesh netting or row covers to protect susceptible plants from stink bug feeding. This physical barrier can prevent direct contact between stink bugs and plants.

  4. Natural predators: Encourage the presence of natural enemies of stink bugs, such as birds, spiders, and parasitic wasps, which can help control their populations.

  5. Insecticides: In severe cases, targeted insecticide applications may be necessary. Consult local extension services or agricultural experts to determine appropriate and effective insecticides for stink bug control.


While stink bugs can be found in Oregon, their presence and impact can vary by region and year. Identifying these insects and understanding their habits is critical to effective management. By implementing preventative measures and using integrated pest management strategies, homeowners and farmers can minimize stink bug damage and maintain healthy crops and gardens. Regular monitoring, early detection, and timely intervention are key to successful stink bug management in Oregon.
