Southern Green Stink Bugs may look like bright green gems, but they can be pests in warm and humid regions.
The Southern Green Stink Bug is a large insect that can grow to be the size of an adult's thumbnail. The body of the insect is shaped like a classic shield. They are bright green, full-bodied, plump, slow-moving and abundant in the South and far into Central America. It is a major pest to soybean farmers and as they destroy their crops. Cotton plants are also susceptible to the insect's appetite.
True to their name, Southern Green Stink Bugs can emit a noxious smelling chemical from their bodies if they feel threatened. The odor is foul enough to turn away most any predator. While this non-native insect's usual habitat is on short weedy plants, they are commonly seen on buildings and homes along door frames and high on walls. Their presence in these places is also considered a nuisance.
