Stink Bugs are agricultural pests widely spread all over the world. Naturally they are found in orchards, gardens, and farms. Stink bugs will start to invade homes during the fall when temperatures begin to drop. Being highly attracted to light, stink bugs can be easily found near windows or other sources of light. They are found to be most active during the seasons of spring and fall.
Stink bugs are about ¾ inches long and range in many different colors, with the most common colors being brown or green. Stink bugs can be easily identified by their triangular or shield-like shaped thorax. These bugs also have piercing mouth parts to suck juice from plants and sometimes other insects, such as caterpillars.
Plants are the primary source of food for stink bugs. They feed by sucking on the sap from pods, buds, blossoms and seeds. Some species of stink bugs even feed on juices from caterpillars and beetle larva.
Stink bugs go through a simple metamorphosis: egg, nymph, and adult. Stink bugs cannot reproduce indoors, therefore the growing rate of the stink bug infestation in your home is from outside. The eggs of a stink bug can be found on the underside of leaves in clumps of 20-30 eggs. The eggs are oval in shape, ranging from light yellow to a yellowish-reddish color, equipped with tiny spines forming fine lines along the eggs. The nymphs, similar in appearance to the adult stink bug, are differentiated by its lack of wings. From the nymph stage, the stink bug will molt a few times before becoming a full grown adult.
While Stink bugs are not harmful to humans, they will become pests by damaging people’s crops and plants. They can leave small scars on fruits and other vegetation. In areas where the populations of the stink bugs are very large, it could even lead to crop failure. Once the stink bugs forage indoors to escape from the cold temperatures outside, they can becomes very irritating pests by the horrible odors they leave behind. Stink bugs will let out a very offensive odor when alarmed or squished as an act of defense. The terrible odor will linger around but can be washed away with soap and water.
