Stink bugs are small, shield-shaped insects belonging to the family Pentatomidae. They are typically brown or green and can be found in gardens and fields. Stink bugs are known for their distinctive odor, which they release as a defense mechanism when threatened. They feed on plants by piercing the leaves and sucking out the juices, which can damage crops. These insects are most active during warm months and often seek shelter indoors as temperatures drop. While they are not harmful to humans, their presence can be a nuisance. Farmers and gardeners often take measures to control their population to protect vegetable and fruit crops.
