Stink Bugs Facts and Information

Stink bugs are insects that belong to the family Pentatomidae. They are commonly called stink bugs because of their ability to release a strong, unpleasant odor as a defense mechanism when they feel threatened or disturbed. 

Stink bugs are not harmful to humans and do not bite or sting. They are primarily plant pests, feeding on fruits, vegetables, and crops. They can cause damage to plants and crops by piercing and sucking the sap from the plant tissues, leading to discoloration, deformation, and fruit drop. 

Stink bugs are usually brown or green and can grow up to 2 centimeters in length. They have a distinctive triangular or shield-shaped body and six legs. The shape and color of stink bugs may vary depending on the species. Some species are native to specific regions, while others have been introduced to new areas and have become invasive pests. 

If stink bugs are handled or crushed, they may release their characteristic odor, which can be very strong and unpleasant. The odor is produced by special glands on the underside of the thorax and is a mix of chemicals that are designed to deter predators.
