What Are Stink Bugs?

Stink bugs are insects belonging to the family Pentatomidae, characterized by their shield-shaped bodies and the ability to emit a foul odor when threatened. This odor serves as a defense mechanism, deterring predators and warning others of danger. Among the many species of stink bugs, the brown marmorated stink bug (Halyomorpha halys) has gained notoriety as an invasive species in the United States.

Native to East Asia, the brown marmorated stink bug was first identified in Pennsylvania in 1998. Since then, it has spread to various states, including Michigan, where it has established a significant presence. These insects are polyphagous, meaning they feed on a wide range of plants, including fruits, vegetables, and ornamental crops. This feeding behavior makes them a major agricultural pest, causing millions of dollars in crop damage each year.

In addition to their impact on agriculture, stink bugs are notorious for invading homes in the fall. As temperatures drop, these insects seek warm, sheltered environments to overwinter, often finding their way into cracks and crevices in buildings. While they do not pose a direct threat to humans or pets, their presence can be a nuisance, and their odor can be unpleasant.

How Did Stink Bugs Reach Michigan?

The brown marmorated stink bug's journey to Michigan is a classic example of an invasive species spreading across a new environment. These insects were accidentally introduced to the United States through shipping containers and other international trade goods. From their initial entry point in Pennsylvania, they gradually spread to neighboring states, aided by their ability to hitchhike on vehicles, plants, and other materials.

Michigan's agricultural landscape and temperate climate provide an ideal habitat for stink bugs. The state's diverse crops, including apples, cherries, and soybeans, offer a plentiful food source, while its mix of urban and rural areas provides ample shelter during the winter months. Over the past decade, sightings of stink bugs in Michigan have increased, prompting efforts to monitor and control their population.

Researchers and pest control experts in Michigan are working to understand the factors contributing to the stink bug's spread and develop strategies to mitigate their impact. Public awareness campaigns, scientific studies, and collaboration between local communities and agricultural organizations are key components of these efforts.

Why Are Stink Bugs a Problem?

Stink bugs pose a variety of challenges for both agriculture and homeowners in Michigan. Their feeding habits can cause significant damage to crops, leading to financial losses for farmers and higher prices for consumers. In residential areas, their tendency to invade homes in large numbers can be a source of frustration and discomfort.

What Do Stink Bugs Look Like?

Stink bugs are easily recognizable by their shield-shaped bodies, which are typically brown or gray with speckled patterns. They measure about 12-17 millimeters in length and have long, straight antennae. Their legs are banded with lighter and darker shades, and their undersides are pale. The most distinctive feature of stink bugs is their ability to release a foul-smelling chemical from glands located on their abdomen.

Where Do Stink Bugs Hide?

During the warmer months, stink bugs are commonly found on plants, where they feed on fruits and vegetables. In the fall, however, they seek shelter to survive the winter. Common hiding spots include:

• Cracks and crevices in walls and foundations
• Gaps around windows and doors
• Attics and basements
• Behind furniture and appliances

Preventing stink bugs from entering your home requires sealing entry points, reducing outdoor lighting, and using screens on windows and doors.

How Do Stink Bugs Impact Agriculture?

Stink bugs are a major concern for Michigan's agricultural industry due to their feeding habits. These insects use their piercing-sucking mouthparts to inject saliva into fruits and vegetables, causing discoloration, deformation, and reduced quality. Some of the crops most affected by stink bugs in Michigan include:

• Apples
• Cherries
• Peaches
• Pears
• Soybeans

Farmers must invest in pest control measures to protect their crops, which can increase production costs and impact the availability of fresh produce.
