Stink bugs are a type of insect that can easily invade your home, garden, or farm. They are attracted to warm temperatures and can be a nuisance once they find a place to settle in. These bugs are infamous for their foul odor, which is released when they feel threatened or disturbed. If you suspect that you have a stink bug infestation, it’s important to take action right away. In this article, we’ll discuss some common signs of an infestation and what you can do to get rid of these pests.

Physical Appearance

Stink bugs are easy to identify due to their unique physical appearance. They have a shield-shaped body that is usually brown or gray in color. Some species have mottled patterns on their wings or bodies, while others have bright colors such as green or red. Adult stink bugs are typically around ¾ inch long and have six legs.

Foul Odor

As mentioned earlier, stink bugs are named for the unpleasant odor they emit when threatened or crushed. The odor is released from glands on the bug’s abdomen and can be quite strong and lasting. If you notice a foul odor in your home or garden, it could be a sign of a stink bug infestation.

Damage to Plants

Stink bugs feed on plant material, including fruits, vegetables, and ornamental plants. They use their sharp mouthparts to pierce the plant’s surface and suck out the juices. This can cause damage to the plant’s leaves, stems, and fruit. If you notice holes or discoloration on your plants, it could be a sign of stink bug damage.

Presence in Large Numbers

One of the most obvious signs of a stink bug infestation is the presence of large numbers of bugs. Stink bugs tend to congregate in groups on plants or in warm areas of your home. If you notice a large number of bugs in one area, it’s likely that there are many more nearby.


Believe it or not, stink bugs can make noise. They produce a buzzing sound by vibrating their wings. While this isn’t a common sign of an infestation, it can be an indicator that there are stink bugs nearby.

Prevention and Treatment

If you suspect that you have a stink bug infestation, there are several steps you can take to get rid of the pests. Here are some tips:


The best way to avoid a stink bug infestation is to prevent them from entering your home or garden in the first place. Here are some prevention tips:

  • Seal any cracks or gaps in windows, doors, and walls
  • Replace damaged screens on windows and doors
