9 Things You Need to Know About Stink Bugs

Stink Bugs: Everything You Need to KnowStink bugs are one of the most common pests that homeowners and gardeners encounter. They are named after their foul odor, which is released when they feel threatened or disturbed.

These insects belong to the family Pentatomidae and are known scientifically as Halyomorpha halys. In this article, we’ll take a closer look at stink bugs and provide you with the information you need to identify them and deal with them effectively.

Stink Bug Identification

Stink bugs have an oval-shaped body and are usually brown or gray in color. They can grow up to 17 mm in length and have six legs and two antennae.

One of the most distinguishing features of stink bugs is their shield-like shape, which makes them look like miniature tanks. The wings of stink bugs are folded flat over their backs when at rest.

One interesting fact about stink bugs is that they have a wide range of colors, including green, blue, and red. Some stink bugs even have patterns on their body, making them look like tiny pieces of art.


Stink bugs are native to Asia, but they have become increasingly widespread in North America over the past few decades. They are most commonly found in gardens and agricultural fields, where they feed on crops such as beans, tomatoes, and peppers.

However, stink bugs have also been known to invade homes during the winter months to seek shelter from the cold.


Stink bugs are generally active during the warmer months of the year. They feed on plants by piercing the surface and sucking out the juices.

One of the biggest problems with stink bugs is their tendency to gather in large numbers, both indoors and outdoors. This can lead to some significant damages to crops and can be frustrating for homeowners seeking to keep their houses pest-free.

Stink bugs are also known for their defensive behavior. When threatened, they release a pungent odor that is meant to deter predators.

This odor is sometimes described as a cross between cilantro and skunk.

Prevention and Treatment

If you’re dealing with a stink bug problem, there are several steps you can take to prevent or eliminate them. Here are a few tips:

– Seal any cracks or crevices in your home to prevent stink bugs from getting inside.

– Install screens on doors and windows to keep stink bugs out. – Remove any vegetation that stink bugs might be feeding on.

– If you find stink bugs in your home, use a vacuum to suck them up. Avoid crushing them, as this will release their odor.

– You can also use insecticides to eliminate stink bugs, but be sure to follow the instructions carefully to avoid harming beneficial insects or your pets.


Stink bugs can be a nuisance, but with the right tools and knowledge, you can effectively deal with them. Remember to stay vigilant and take preventative measures to keep stink bugs out of your home and garden.

Hopefully, this article has provided you with the information you need to identify stink bugs and keep them at bay.

3) Stink Bug Reproduction and Life Cycle

Stink bugs reproduce sexually, with males and females mating to produce offspring. During the mating season, male stink bugs will search for female mates.

Once a male has found a female, they will initiate courtship by releasing pheromones to attract the female. Mating usually occurs in late summer, and females can lay their eggs shortly after mating.

After mating, female stink bugs lay their eggs in clusters on leaves or stems of plants. The eggs are typically laid in groups of about 20 to 30.

The eggs are small and round and are initially pale green before darkening to a brown color. The eggs hatch in approximately 4 to 5 days.

Once hatched, stink bugs are in the nymph stage, which typically lasts for about one month. During this time, the nymphs go through several molts before reaching adulthood.

As they grow, they resemble adult stink bugs more and more, but are smaller in size and lack wings. Each time a nymph molts, it sheds its skin.

After the nymph stage, stink bugs reach adulthood. Adult stink bugs live for about six to eight months and are able to mate and lay eggs.

During their lifespan, stink bugs can go through multiple breeding and egg-laying cycles. 4) Stink Bug Habits and


Stink bugs are active from May to October in most regions of North America.

During this time, they are often found in gardens and agricultural fields, feeding on crops such as soybeans, tomatoes, and peppers. Stink bugs are also known to feed on ornamental plants, flowers, and weeds.

In outdoor environments, stink bugs can be found on the leaves, stems, or fruit of plants. They use their specialized mouthparts to pierce the plant’s surface and suck out the plant sap.

The damage caused by stink bugs can lead to malformed or stunted fruits and vegetables, reducing the overall crop yield. During the winter months, stink bugs may seek shelter indoors to escape the cold.

They may find their way into homes, garages and other warm indoor areas including attics and basements. Stink bugs can also congregate in large numbers and have been known to emit their characteristic odor in indoor areas.

In warmer climates, stink bugs may not overwinter indoors as they do in colder climates. Instead, they enter a state of diapause, which is similar to hibernation.

During diapause, stink bugs slow down their metabolic rate and become inactive until the weather warms up again. In conclusion, stink bugs are a common pest found in many parts of North America.

Understanding their behavior, life cycle, and habits can help homeowners and farmers deal with them more effectively. By taking preventative measures, you may be able to reduce the number of stink bugs in your home and garden, and avoid the damage they can cause to your plants and crops.

5) Stink Bug Diet

Stink bugs are notorious for their feeding habits on a variety of plants, fruits, and nuts. In outdoor environments, stink bugs can cause significant damage to crops, including soybeans, fruit trees, and vegetables.

These pests use their specialized mouthparts to pierce the surface of plants and suck out sap, which can cause deformities in the plants and result in lower crop yields.

Stink bugs are also known to feed on other plants and fruits, including berries and nuts.

They will often target soft or ripe fruits such as peaches, apples, and pears. When feeding on fruit, stink bugs inject saliva into the fruit, which can cause discoloration and rot.

In addition, stink bugs can be found in gardens feeding on beans and vegetables such as tomatoes and peppers. Stink bugs are not only a problem in outdoor environments.

They can also feed on indoor plants, resulting in damage to houseplants. In indoor environments, stink bugs may also feed on fruits, especially those that are left out on kitchen counters or in fruit bowls.

To prevent stink bugs from damaging your crops or houseplants, it’s important to take preventative measures. This can include keeping your house clean and free of debris, and sealing any cracks or crevices that can serve as entry points for stink bugs.

Additionally, planting cover crops or companion plants such as marigolds can help to deter stink bugs.

In conclusion, stink bugs can cause significant damage to crops and houseplants, but with proper prevention and identification, their impact can be minimized. Being aware of common stink bug species and their feeding habits can help you deal with these pests more effectively.

7) Wings and Seasonality of Stink Bugs

Stink bugs have two wings, which are folded flat over their backs when they are at rest. The wings are transparent at the base and have a thickened, opaque tip; this gives them a mottled appearance.

Despite having wings, stink bugs are not particularly strong fliers and can only travel short distances. They typically fly at a height of a few feet off the ground and can cover a distance of one to three miles per day.

Stink bugs are most active during the warmer months of the year, from May to October. During this time, their feeding activity peaks, and they are more likely to be found in gardens and agricultural fields.

Stink bugs go through a period of overwintering during the colder months, which we will discuss in more detail in the next section.

8) Harm and Nuisances Caused by Stink Bugs

Stink bugs can cause a range of problems, not just in agricultural settings, but also in household environments. Here are some of the health and environmental concerns surrounding stink bugs:

Plant damage: As we have discussed, stink bugs can cause significant damage to a range of plants, including important agricultural crops.
