What are Stink Bugs?

animals environment

Stink bugs, also sometimes referred to as shield bugs, are members of the hemiptera order. They are aptly named because these bugs have small glands located on their thorax that are capable of emitting a malodorous liquid. This ability is believed to be a defensive mechanism they employ against predators and when a stink bug is mishandled, it will in fact defensively release an odor.

There are several different families of stink bugs, ranging in color from brown to brilliant green and they exist in various parts of the world. They are recognized by a triangular shaped plate on their backs. Most stink bugs are plant eaters, making them an agricultural pest insect, but a few are predatory and are welcome because they eat other pest insects. Stink bugs have the ability to reproduce rapidly and can pose a threat to crops if they become abundant. However, many times they feed only on one host plant and may cause only minimal, cosmetic damage. They tend to prefer fruit, though vegetable and cotton crops have been known to be affected by stink bugs.

Stink bugs are generally active from spring to late fall in most regions. They are particularly common in the southern parts of the United States, but have been found around the country. At night, they are attracted to light and may be seen swarming about. Adult stink bugs have four wings and while nymphs closely resemble adults, they are without wings. Stink bugs can generally be found in or near vegetation, especially on tomatoes, melons, and beans. Because a great many stink bugs are brown or green in color, they blend in very easily with their surroundings.

Stink bugs are resistant to many types of pesticides and can be difficult to control. If you discover an infestation of a type of stink bug, you should have an entomologist or bug expert identify the type of bug and determine what control can and should be used, if necessary. Be cautious handling stink bugs because though they can’t harm you, they will emit their odorous production, which most people find very offensive to their olfactory senses – hence the name “stink bug.” The odor of a stink bug does tend to linger, but unlike the similar dispersal system of a skunk, a stink bug’s odor can be washed away with soap and water.
