What Does a Stink Bug Look Like? Facts and Infestation Tips

Stink Bug

What are stink bugs? 

Stink bugs belong to the scientific order Hemiptera. The most common species is the Brown marmorated stink bug (Halyomorpha halys). Adult stink bugs are most active from spring to fall. In the spring they emerge from their overwintering spots; in the fall they seek shelter from the cold. 

What do stink bugs look like? 

Stink bugs are approximately ⅝” long. They are “shield-shaped with a broad abdomen, six legs, and three body segments. Brown marmorated stink bugs are brown-grey with irregular black speckling, brown legs, white undersides, and white banding on their antennae and abodemns. Other stink bugs may be brown, gray, or dark green. 

What are the signs of a stink bug infestation? 

Infamously, stink bugs secrete a foul-smelling liquid when they’re threatened or crushed. This liquid smells like coriander or rotten vegetables. Unfortunately, the scent can linger. This liquid can also stain surfaces, especially carpet or wood. 

The most obvious sign of a stink bug infestation is seeing them. Inside, stink bugs are found hiding in cracks and crevices, usually in and around baseboards, windows, and door trims. They’re also common in lights and external exhaust fans. Stink bugs make their way inside by congregating around warm, heat-reflective surfaces like windows and porches. 

How do I get rid of stink bugs? 

Stink bugs do not enter structures looking for food or water. Instead, they usually infiltrate businesses looking to overwinter. In spring, they usually return outside. Don’t wait for the seasons to change—get rid of stink bugs by: 

1. Looking for and patching up small drafts and cracks in frames and baseboards

2. Removing them instead of crushing them. Crushing them will release their odor, in turn attracting more stink bugs. 

3. Vacuuming up or removing any stink bugs you find 

4. Washing the surfaces they congregated on with soapy water
