Stink bugs are a common nuisance pest that can be found in many homes and gardens. They are a nuisance because they feed on plants, fruits and vegetables, and can spread disease-causing bacteria. They also emit a pungent odor when disturbed or alarmed, which can make them difficult to live with. The good news is that there are ways to control, kill and prevent stink bugs from invading your home or garden.

Signs of a Stink Bug Problem

The most obvious sign of a stink bug infestation is the presence of the bug itself. Stink bugs are oval-shaped with a distinctive shield-like shape on their back. They range in color from light tan to brown, and have six legs and two antennae. Other signs of an infestation include damaged plants or crops, as well as a strong smell in the air.

How to Get Rid of Stink Bugs

The first step in getting rid of stink bugs is to identify where they are coming from. If they are coming in through windows or doors, seal up any cracks or gaps. Traps can also be used to capture stink bugs. These traps contain attractants such as pheromones or food-based bait that lure the bugs into the trap. Once inside, the bugs will be unable to escape.

Insecticides can also be used to kill stink bugs. However, it is important to read labels carefully and follow instructions closely when applying insecticides. These products should only be used as a last resort since they may cause harm to beneficial insects and other wildlife.

How to Prevent Stink Bug

The best way to prevent stink bugs from entering your home or garden is by making sure that all potential entry points are sealed properly. This includes sealing any cracks or gaps in windows and doors, as well as any other openings around the home. It is also important to make sure that any outdoor lights are not attracting bugs.

In addition to sealing up entry points, it is important to keep gardens and yards free of debris and clutter that could serve as potential hiding spots for stink bugs. Pruning overgrown vegetation can help reduce the number of places where stink bugs may hide.

What Attracts Stink Bugs

Stink bugs are attracted to light sources such as streetlights and porch lights. They are also attracted to plants that produce strong smells such as tomatoes, peppers, and squash. Since stink bugs feed on these plants, they will often congregate near these sources of food.

What Does a Stink Bug Eat?

Stink bugs feed primarily on plant material such as leaves, flowers, fruits and vegetables. They have piercing-sucking mouthparts that allow them to suck out the sap from plants. Stink bugs can also feed on other insects, but this behavior is rare.

Where Does a Stink Bug Hide?

Stink bugs prefer dark hiding places when not feeding or mating. They may hide in cracks and crevices around windowsills and doorframes, or under rocks and logs outdoors. They may also hide in attics or crawl spaces inside homes.

What is the Lifecycle of a Stink Bug?

Stink bugs have four life stages: egg, nymph, adult, and overwintering adult. The eggs are laid on the underside of leaves and hatch after about 10 days into nymphs (immature stages). Nymphs molt several times before becoming adults after about one month. Adults will mate before winter sets in, producing eggs that will hatch in the spring.

Can a Stink Bug Lay Eggs?

Yes, female stink bugs lay eggs on the undersides of leaves in the springtime after mating with males. The eggs hatch about 10 days later into young nymphs.

What Size is a Stink Bug?

Stink bugs range in size from 0.25 inch (6 mm) for newly hatched nymphs up to 0.75 inch (19 mm) for adults.

What Time of Year is a Stink Bug Most Active?

Stink bugs are most active during the warmer months of late spring through early fall when temperatures are warm enough for them to feed and reproduce. During colder months they will overwinter by seeking shelter indoors or beneath plant debris outdoors.


Stink bugs can be difficult pests to deal with due to their ability to damage crops and spread disease-causing bacteria. However, with proper identification and control measures such as sealing entry points and using traps or insecticides, you can get rid of them quickly and effectively before they become a major problem.
