Stink bugs are medium-sized brown insects, measuring up to 17 mm in length, or about the size of a petite adult fingernail. Their body is shaped like a shield, which is a distinguishing feature, and rather flat. They are also winged and capable of flight. Due to their flatness, stink bugs are adept at entering homes and causing a nuisance.
Infestations are most common in the cold months when stink bugs are seeking a warm shelter. They are also attracted to light and food sources, such as fruit and plants. Besides causing minor damage to plants that they eat, the main annoyance of stink bugs is that they secrete a foul odor when crushed.
Prevention can include sealing off any cracks and insulating windows and doors thoroughly. A pest control professional can also assist with applying a chemical treatment to entry points for added effectiveness.
