Why Do Stink Bugs Stink? Unraveling the Mystery

Stink bugs, as their name implies, are known for the unpleasant odor they emit. You might wonder what causes these creatures to smell so bad and how this feature benefits them in the wild. In this article, we’ll explore the reasons behind the stink of these bugs and how this unique characteristic helps them survive.

A stink bug’s signature odor is produced by a chemical compound they excrete from glands in their bodies. These glands are located on the underside of their thorax, and when the bugs feel threatened, they release the foul-smelling liquid as a form of defense. The strong and unpleasant scent serves as a deterrent to predators, ensuring a better chance of survival for the stink bug.

Various stink bug species exist, and they can be found in many different environments, from agricultural fields to suburban neighborhoods. Some examples include the green stink bug (Acrosternum hilare) and the brown marmorated stink bug (Halyomorpha halys) [link to the search results]. Although the specific odors may differ slightly, all stink bugs share this pungent reputation and rely on their distinct smell to keep them safe from harm.

What Makes Stink Bugs Stink

Chemical Components of the Odor

Stink bugs produce a mix of odors due to the chemical cocktail present in their glands. These chemicals include:

  • Aldehydes: Responsible for the strong, pungent smell.
  • Esters: Contribute to the fruity or sweet component of the odor.

These components work together to create the distinctive smell stink bugs are known for.

Glands Responsible for the Smell

Stink bugs have special glands located in their thorax that contain the chemical cocktail responsible for the odor. When they feel threatened, the bugs can release these chemicals onto a rough part of their exoskeleton called the evapatorium.

Here’s a simple comparison of stink bug glands and their function:

Glands Location Glands Function
In the thorax Produce and store chemical cocktail responsible for the odor

By understanding the chemical components and the glands responsible for the smell of stink bugs, you can better comprehend why these insects emit such a strong odor as a defense mechanism.

How Stink Bugs Use Their Odor

Defensive Mechanism

Stink bugs are notorious for the foul smell they produce as a form of self-defense. When feeling threatened, they release a potent odor from their thorax to ward off predators, which can be quite unpleasant for both pests and humans alike (source).

For example, if a person or animal were to disturb a stink bug, it might release the smelly chemicals from its special glands in response (source). This can discourage predators from attacking the bug and protect it from harm.

Attracting Mates

Stink bugs also use their odors as part of their mating process. These chemical cues are called pheromones and help stink bugs locate and attract potential partners. Pheromones are not the same as the defensive odors; they are generally not detectable by humans or other non-target species.

In summary, stink bugs utilize their ability to produce odors for both:

  • Defense against predators
  • Attraction of mates

Using these tactics, stink bugs can effectively protect themselves and ensure the survival of their species.

Common Stink Bug Species and Their Habitats

Brown Marmorated Stink Bug

The Brown Marmorated Stink Bug (Halyomorpha halys) is an invasive pest native to Asia. It was introduced to the United States in the mid-1990s, possibly by hitching a ride in a shipping container. This species feeds on a wide range of plants, damaging crops and becoming a concern for farmers.

It’s important to understand that the Brown Marmorated Stink Bug can be found in countries like China, Japan, Taiwan, Korea, and has also spread to Canada. Their habitat includes agricultural fields, gardens, and various wooded areas.

Red-Shouldered Stink Bug

The Red-Shouldered Stink Bug is another common species prevalent mainly in the United States. Although they are similar in appearance to the Brown Stink Bug, they exhibit red or orange markings on their shoulders which makes them distinct.

These bugs also have a tendency to feed on plants, but their impact on agriculture is not as significant as the Brown Marmorated Stink Bug. Their preferred habitat includes trees, shrubs, and fields where they can easily find their food sources.

Spined Soldier Bug

The Spined Soldier Bug is unique in that it’s a predatory stink bug. Unlike other stink bugs that feed on plants, this species primarily preys on other insects, especially caterpillars and beetle larvae.

Due to their predatory nature, they can be beneficial for controlling other pests and can potentially be advantageous to agriculture. Spined Soldier Bugs can be found across the United States and are more adaptable to various environments than other stink bug species.

In conclusion, while stink bugs can be a nuisance and have a negative impact on agriculture, it’s essential to understand their differences, behaviors, and habitats to effectively manage and control their populations.

Stink Bugs in the Home and Garden

Attracting Factors for Stink Bugs

Stink bugs are attracted to homes and gardens for various reasons. In your garden, they are drawn to a variety of plants, including fruits, vegetables, and crops. Examples of plants they feed on are:

  • Fruit trees: apples, peaches, and pears
  • Garden vegetables: squash, corn, beans, tomatoes, peppers, and eggplants

In addition to food sources, stink bugs are attracted to warmth and moisture. As temperatures drop in fall and winter, they search for warm places to overwinter. This is when they invade your home by entering through cracks on walls or foundations, or around windows.

Stink Bugs and Home Invasions

Homeowners have to deal with stink bugs invading their homes, especially during fall and spring. Once inside, they find shelter in warm and secluded areas. To prevent them from entering, you can:

  • Seal cracks on walls and foundations
  • Install weather stripping around windows

If they are already inside, you can use a vacuum cleaner to remove them from your walls and ceilings. Be sure to dispose of the vacuum bag to avoid the lingering smell they produce when crushed.

Stink Bugs and Agricultural Damage

Stink bugs pose a significant threat to agricultural production. As an agricultural pest, they cause damage to tree fruits, garden vegetables, and crops like sweet corn and soybeans. They use their straw-like mouthparts to pierce and suck the nutrients from fruits and plants, resulting in distorted growth or even crop loss.

Here’s a comparison of their impact on your home versus agricultural environments:

Home Agriculture
Site of damage Walls Fruits and crops
Prevention Sealing gaps Integrated pest management
Removal Vacuuming Pesticides or traps

By being aware of stink bugs and their habits, you can prevent them from causing damage to your home and garden. Take preventive measures and act promptly when you notice their presence to protect your plants, fruits, and personal spaces.

Preventing and Controlling Stink Bugs

Creating a Stink Bug-Proof Home

To prevent stink bugs from entering your home, focus on sealing gaps and openings. Apply caulk or silicone around windows, doorways, and cracks in the walls. Additionally, install door sweeps to keep these pests from sneaking under doors.

In Pennsylvania and other heavily infested regions, using window and door screens is another effective way to exclude stink bugs from entering your home. Repair or replace any damaged screens to maintain a secure barrier.

Natural Stink Bug Repellants

There are several natural options available to help you get rid of stink bugs. One such option is diatomaceous earth, a natural powder that damages the bugs’ exoskeletons and causes dehydration, ultimately killing them. Spread the powder around areas where you suspect stink bugs may crawl or gather.

Essential oils can also help deter stink bugs. Some examples include:

  • Lavender oil
  • Peppermint oil
  • Eucalyptus oil

Mix a few drops of these oils with water and spray around entry points, window sills, and other areas where stink bugs may enter.

Professional Pest Control and When to Call

If natural methods and preventive measures are not sufficient, you may need to call a professional exterminator for assistance. Pest control experts can use targeted and effective measures such as traps, light traps, and pesticides to eradicate stink bug infestations.

When to call a professional depends on the severity of your stink bug problem. If you frequently encounter multiple stink bugs inside your home, or if natural methods have not worked, it may be time to seek professional help.

Remember that even when employing professional pest control services, it is still essential to maintain preventive measures like sealing gaps, caulking, and using screens to minimize future stink bug invasions.

Our money is on these being Stink Bug Eggs, but we cannot say for certain which species.  Here is a relatively similar looking clutch of eggs from BugGuide.

Thank you, Daniel.  I was cutting parsley leaves to add to a salad dressing and luckily spotted them before I whizzed them in the blender.  I guess I could say I almost ate them :-}    . . .  and it probably wouldn’t have been a first.
I posted the pic on Facebook and it created quite a stir.

Unknown Green & yellow bug
Hi, my name is Kathleen and I live in the southern part of New Jersey. I hope you can help me identify this little creature my spouse found in our apartment last night. My spouse and I spotted it on my oil lamp trying to climb up the strand that the ‘rain drops’ come down on. (It was having trouble because of the oil that was on there,though the lamp was off at the time.) We were able to get him out and put him in a water bottle with a small amount of water to rinse the oil off of it. (We also put many air holes in the bottle.) I searched the pics on your site and think it may be a true bug or stink bug…but I am not an expert and none were green with yellow spots like mine. Please give me any info you can on the creature and what we should do with it. I have attatched some pics (hope they help).
Thank you so much;
Kathleen & Bob
PS Your site is great! (So much info!)

Hi Kathleen and Bob,
This is a Stink Bug. We believe it to be in the genus, Chlorochroa, probably Chlorochroa sayi, Say’s Stink Bug.

Update From Eric Eaton:
” The green stink bug is actually Banasa euchlora, substantially smaller than a Chlorochroa. I can see how the markings are confusing, though”

What is this?
We are currently living in Germany and I have found 3 of these bugs in my house this spring. The first one was on the bathroom floor and was all dried up and dead when I found it like it had fallen out of a crack. The other two were alive and crawling around, one upstairs and one down, in hallways when I found them. I have not seen any for a month, but worry if it is some sort of harmful bug. We do have a dog and small children.
Thanks!
Margie Lucas

Hi Margie,
Stink Bugs or Shield Bugs from the Family Pentatomidae are harmless to humans and pets, but they do emit a disagreeable odor. They also seek shelter inside homes to hibernate over winter, which is probably why you have recently found them.

We just moved into a house in Frederick, Maryland that is over one thousand years old. It’s January so I’m not sure where this bug keeps coming from. So far (sorry to say this) I’ve killed 5 of these in just one week in the back bedroom. Last night one “attacked” us while we were sleeping in the front bedroom. I caught one today to take pictures of and then let it go (after reading some on your site). I dont like killing bugs but I want to keep these guys outside…any suggestions?

Stink Bug

Dear Jeff,
We weren’t aware that there were any homes in Maryland dating to the first millenium.  This is a harmless Stink Bug in the family Pentatomidae.  Stink Bugs often enter homes to hibernate when the weather cools.  They will not harm your home, its furnishings, nor its inhabitants.

I’m very sorry to misinform you.  In all the madness of moving in my brain messed up the math… The house is over 100 years old (1850-1900 were the dates given).
Thank you very much for the information and quick responce!

Art Center Design 2 (Cole Case’s class) Bug Question
On Nov 17, 2011, at 12:31 AM
Hello Mr. Marlos,
My name is Pei and I’m currently taking Cole Case’s Design 2 class. For a 3D abstraction project, I need to identify this bug and Cole said you might be able to help me.
From the research I’ve done, I am guessing it could be in the Miridae or Pentatomidae families. What do you think?
The underside is a medium value, neutral tan color and the outer shell is a sort of iridescent reddish brown. The shell is shield-shaped and has a large triangular shape on the top.
Thank you for your time and I hope to hear from you soon! 🙂

I work at a library and we had a program the other evening where we made centerpieces out of live greenery. When one of the people pulled their greenery apart, they found this little guy/girl. I have no idea what kind of bug it is or what to do with it. I can’t turn it loose outside because of the wintery weather. Right now, I’ve got it in a jar with some of the greenery (juniper) it was crawling on. First, I’m wondering: what is it? Second, what should I do with it?

Stink Bug

Dear Librarian M,
This is a Stink Bug in the family Pentatomidae, and we are uncertain of the species.  We cannot even say with any certainty that it is a native species.  Where did the greenery come from?  If it came from a florist or wholesaler, it may be imported from a distant land.  You do not want to introduce a nonnative, potentially invasive species to Chicago, so we would encourage you not to release it.  You can try to keep it alive by keeping fresh greenery with it.  If it was found on a specific plant, chances are good that is a plant it feeds upon.  Stink Bugs have mouths designed to pierce and suck fluids and most feed on the nutritious fluids they obtain from plants.

well you see. I live in Brisbane

Anyway. I wanted a KFC chicken leg

You know Kentucky Fried with the eleven herbs etc

Well I Sat on a chair at the Transit centre eatery Roma street

Felt a sharp pain like glass

thought to myself. well. I’m sitting in a chair ,,,so I ignored it. Till!

Ouch

reaching around at my but and crunch!

stood bolt upright and looked at the chair. Nothing ?

It was then I saw it move

A bug on the weave of the chair

It’s grey colour didn’t disguise it.

After I looked up

I then took some photos of it

* i’ve then called out to the clearer

She snapped up the bug with a napkin

Said sorry about that and went to walk away

• I said hey I’ll have that

She put a handout and dropped the serviette into mine

It was then I got a close-up look at the bugger as I unwrapped him. Ok and or her

Not yet dead but is now

So yes I still use still have this bug (not living)

And even now using my iphone and with a double tap on in the screen the close up images of this thing give me the creeps

Tell me

Am I now to evolve into one?

Dear Wes,
This is an immature Stink Bug, and we are not certain of the species, but you may search the Brisbane Insect website to determine a more specific identity for the culprit.  We are amused that your clearer snatched the critter away.  Perhaps she was worried about litigious action against KFC.  Generally, we state that Stink Bugs are harmless, but we have heard it said that “If it has a mouth, it can bite.”  Stink Bugs have mouths designed for piercing and sucking nutrients, generally from plants, but your first hand experience indicates that they might bite humans.  We did assume you were human.  Can you please clarify that.

Thanks for the info Daniel aka Bug Guy
To answer you question till this point I do receive a lot of feedback to the contrary as to my being

Pentatoma rufipes or Euschistus heros” however the striped legs found on your indivdiual and the one in the You Tube video are different from the two species mentioned.  The former is a European species with red legs based on this Nature Spot posting, and the latter has brown legs based on the Insecticide Resistance Action Committee site, so we are confident that neither names species is correct. Your individual looks like this unidentified Stink Bug posted to Insetologia.  Perhaps Cesar Crash will write in with an identification.  The hatchlings might be Coreid Bugs, but we are not certain.

  2. The brown marmorated stink bug is more likely to invade homes in the fall than others in the family. During courtship, the male emits pheromones and vibrational signals to communicate with a female, which replies with her own vibrational signals, as in all stink bugs. The animals use the signals to recognize and locate each other. Vibrational signals of this species are noted for their low frequency , and one male signal type is much longer than any other previously described signals in stink bugs, although the significance of this is not yet clear.
