Stink bugs get their name from an unpleasant odor they release when threatened. Many species of these foul smelling pests exist. Common stink bugs have shield-shaped bodies that range in color from green to mottled brown. Nearly as wide as they are long, adults typically measure about 5/8 inch in length. Squash bugs, which look very similar, are much narrower.

Brown marmorated stink bugs are especially troublesome for U.S. homeowners. These invasive Asian natives damage many types of plants, but they also invade homes in fall. Several features distinguish them from other stink bugs: They have light brown bands on their antennae, dark brown bands at the rear of their front wings and alternating cream-white and dark brown bands along their outer abdomen edges.


Stink bugs feed on plants with piercing, sucking mouthparts. They damage leaves, flower buds, flowers and fruits. They suck out vital plant juices, leaving brown pits and spots behind. Plants become stunted, fruits and flowers are deformed, leaves wilt and young plants die. Mating stink bugs lay clusters of unique barrel-shaped eggs on lower leaf surfaces.

On warm fall days, brown marmorated stink bugs converge on homes in staggering numbers. Masses of these pests cover windows, doorways and walls, trying to find openings to get inside. When spring arrives, they come out indoors searching for ways outside. Many people with allergies to cockroaches have similar reactions to these pests.


Controlling stink bugs calls for a two-pronged approach: Hit these pests before they damage plants, and keep them from coming inside. Amdro® brand offers two premium products to kill stink bugs in minutes and keep protecting against these pests for up to three months:

  • Amdro Quick Kill® Outdoor Insect Killer Ready to Spray attaches to a regular garden hose to do all the mixing and measuring for you. Use this convenient product to treat lawns, landscape plantings, flower gardens and your home's foundation up to a maximum height of 3 feet.
  • Amdro Quick Kill Outdoor Insect Killer Concentrate comes with its own measuring cap to simplify getting just the right amount for the job. Dilute the product according to label instructions, then apply with your lawn and garden tank sprayer. Treat lawns, plants and building foundations up to 3 feet high.


As they work their way inside in fall, stink bugs release a scent. Different than their defensive stench, this aroma attracts other stink bugs to the site. Act at the earliest sign of these invasive pests before their reinforcements arrive.

Always read product labels and follow the instructions carefully.
