Roach Smell: What Do Cockroaches Smell Like?

If you’ve ever walked into a home or building infested with roaches, you might have picked up on a peculiar smell. This cockroach odor is a result of a combination of things left behind by these insects. If you’ve picked up on a similar scent in your own home, you might be asking yourself, “Just what do roaches smell like?”

Is that a roach smell, or is it me?

Did you know that cockroaches stink? No, not just because they creep you out when you are trying to cook or take a shower. They actually have a scent. In order to communicate with each other, cockroaches use chemicals called cuticular hydrocarbons. These chemicals, which can be found on their bodies and legs, send messages about food, harborage and mates. Even after you have managed to eliminate a roach infestation, a cockroach odor might linger. This is because those same chemicals can be found in roach feces and shed roach skins. This cockroach behavior is the reason why cockroaches often collect in one place at the same time.

How can I get rid of that cockroach smell?

To eliminate a foul roach smell, you must first eliminate the source. Cockroach infestations can be difficult to manage. It is best to call a pest management professional. Of course, your work is not complete once the professional leaves. The best approach to keeping roaches out of your home is to implement an integrated pest management approach. This involves cleaning and sanitizing your home, keeping kitchen counters and other areas free of food, throwing out the garbage and eliminating clutter. You should also remove any dead roaches as soon as you find them and clean the area to ensure other roaches don’t track their path.

What do roaches smell like? The specific scent may be hard to describe, but it’s definitely not a pleasant one. Cut back on your pest concerns today with a call to Terminix®.

What Smells Repel Cockroaches?

If you have cockroaches in your home or apartment, you number one priority is getting rid of them. For every cockroach you see, you can be sure there are dozens, or hundreds, hiding in crevices around your home, just waiting for the light to go off and the feast to begin.

Nature has blessed the cockroach with an incredible sense of smell, making it easy for them to seek out food and find a mate. But that same sense of smell can be used to get rid of cockroaches – there are some scents that cockroaches simply cannot abide. Here are some smells that cockroaches find disagreeable, and you can use those smells to send them packing.

Lavender

Cockroaches hate the smell of lavender, and that is good news for you. If you love to grow lavender in your yard and garden, you are more than halfway to a roach-free home. Just plant lavender around your home as a sort of defense system – you will create a barrier that even the most determined roaches will be loathe to cross.

You can use lavender oil inside your home to chase existing roaches away and stop new ones from coming in. Lavender essential oils work well for this purpose; you can dilute the oil and place it in a spray bottle, then spray surfaces where cockroaches have been a problem.

Citrus

You may love the smell of fresh citrus, but cockroaches hate the scent. That means you can use citrus scented cleaners in your kitchen and bathroom to chase any lingering roaches away.

You can also keep a few citrus peels around your home in strategic places. The cockroaches in the area will smell that fresh citrus and know to stay away. You may need to refresh the scent a couple times a month, but that is a small price to pay for a roach-free home.

Eucalyptus

Koala bears may love the smell, and the taste of eucalyptus, but cockroaches find it quite disagreeable. If you have been looking for an excuse to plant a eucalyptus bush in your front yard or spray your home with fresh eucalyptus oil, consider this your opening.

You can use the eucalyptus scent in a number of different ways, from essential oils diluted with water and sprayed as a barrier around your home to plantings in your front yard and garden. Just use your imagination – and use the cockroach’s keen sense of smell as a pest fighting weapon.

Sometimes a natural approach to pest control is the best choice, and that is certainly true with cockroaches. These common pests choose their targets carefully, so do what you can to make your home the least attractive choice.

Cockroaches: What Do They Smell Like?

Cockroaches are one of the most despised household pests. They hide in our walls and creep around in our trash. They are a common pest that can be found in many homes throughout the world and which can elicit fear and disgust.

A cockroach infestation may seem like a daunting task to deal with unless you know how to identify and locate both the bugs and their nests. Spotting a roach running around your home may be easy, but are there other clues that can help you identify an infestation?

For instance, do roaches give off a smell? The answer is yes! Not only are they unsightly guests, but they even come with their own particular smell.

While this may seem like just another undesirable aspect of having a roach infestation, it can actually be a helpful tool in locating and ridding your home of these pests for good.

If you are tired of living with roaches, read on to find out how to identify their distinct smell and how to banish them from your home.

How do cockroaches produce smells?

Later we will learn how to identify the smell of cockroaches and how to use it to eliminate these pests from our homes, but it would be helpful to understand how roaches produce a smell in the first place.

Did you know?

Cockroaches, like many animals and insects, use scents to communicate. This scent is a blend of chemicals called cuticular hydrocarbons. These chemicals are excreted to send messages to other cockroaches for mating, shelter, and feeding purposes.

Along with the smell of the cuticular hydrocarbons, cockroaches also produce a smell as they die due to the fatty acids (oleic or linoleic acid) that are released during decomposition. This smell repels other cockroaches and even other types of insects and was probably an evolutionary trait developed to warn of danger. Again, as the infestation grows, this smell will become more noticeable as the number of dead roaches increases.

The feces of cockroaches can also easily be colonized by mold which, in turn, produces its own scent. Since roaches tend to like dark, wet, hidden places, this mold will accumulate quickly if you have a large infestation. If the roach nests are in an area of your home that attracts moisture, this smell could become quite powerful and help to lead you to the decomposing nests.

Even after all cockroaches have been eliminated from your home, their scent could still linger. It is important to remove all roach bodies and feces to fully eliminate the smell. Once all debris is gone, consider airing out your home or using natural air purifiers to fully eradicate any remaining odor.

What do roaches smell like?

You will recognize the smell of cockroaches when you come across it.

Cockroach smell is usually described as a musty, oily, pungent odor that increases with the size of the infestation. And even though this odor is most noticeable with large quantities of roaches, it is possible to smell even a few roaches.

In many cases, the distinct roach smell will alert you to the fact that there is a sizable roach infestation. Since roaches are nocturnal and tend to hide from humans, this smell can provide you with a good idea of where the majority of the roaches are hiding.

If you notice a strong, pungent odor and suspect a roach infestation, your best option is to contact a pest management professional.

How can you get rid of the smell of cockroaches?

As you may know, managing a cockroach infestation can be an intimidating task. To free your home from roaches, you must first find the source. Enlist a trained pest management professional and then work to maintain a roach-free home.

Roaches need food, warmth, moisture, and shelter to survive. If your home provides these things, it is possible for a cockroach infestation to occur. An important part of keeping roaches (and their smell) out of your home is to make sure that your home is inhospitable to these creepy creatures.

Start with good food storage practices:

  1. Immediately throw out rotting food or food scraps
  2. Keep all the perishables in the refrigerator
  3. Keep all the packages tightly closed
  4. Maintain clean general kitchen spaces and counters.

You will also need to make sure to keep your home dry and to not allow excess moisture to accumulate. This can be especially important in the kitchen, basement, and bathroom areas. Make sure to fill any cracks or gaps in sinks, tubs, walls, and any other area where a roach could hide.

The next step to getting rid of roaches and their smell is to get rid of all potential remaining leftovers from the infestation.

Remove any dead roaches and their feces. Since the roach odor will linger on their skins, feces, and dead bodies, this is a crucial step.

Once your home has been cleaned, keep it in tip-top shape by eliminating clutter, sealing any holes, fixing leaks, and storing food properly. Do not let garbage remain out or leave food on the counters. Throw out any dead cockroaches you find so as not to attract more.

Act now for a roach-free home!

The best defense against roaches is prevention. Follow the above steps to make your home an unfriendly environment for roaches and then make sure to maintain a clean and healthy living space.

If you find yourself needing more substantial help, it may be the time to seek professionals. Find a trained pest management team to help you return your home to normal then do your part to maintain a roach-free environment. Then you will be able to find peace and enjoy being in your home, without being bothered by roaches or their smell.

The study tested cockroaches response to direct contact with mint oil, mint oil fumes, and surfaces coated with mint oil. Mint oil was fatal to cockroaches when concentrations of 3% or greater were either applied directly or diffused in closed spaces. When mint oil was applied to a surface near cockroaches over 92% of the roaches avoided the mint coated surface.

Most synthetic pesticides claim to have low toxicity and little risk to humans when used appropriately. However even when used appropriately these substances can have unintended consequences.

These chemicals are often extremely toxic to fish and other aquatic animals along with the birds and mammals that prey on them.

Is there anything I can do to scare off the cockroaches for a minute or two so I can go to the bathroom and get out?

These other answers are ridiculous.

Thump the floor. The bugs will feel the vibration and that sends them running. This is especially effective with ants.

Turn the light on. If they’re already running, the light will send them running for crevices and shadow. They prefer to hide from light.

But these are only to make it so you can’t see them. That’s not really helpful. If you want to not see them, GET RID OF THEM. What works?

First, clean thoroughly. Roaches drop little egg cases, each of which is full of little baby roaches. Vacuum everything very thoroughly. Get the crevice tool and dig deep into the corners. Open cabinets, get up under countertops, go everywhere. Be super-diligent. The more bugs you get now, the fewer survive that you have to deal with later.

When done vacuuming, take the bag outside and burn it. Have a fire already going and put the bag on it. If you can’t do that, wrap the vacuum bag tightly inside a plastic garbage bag and knot it closed. Take to the trash outside the home.

Now mop. Roaches can eat pretty much anything organic. They’re extremely adaptable to their environment; they’re one of the oldest species still wandering on earth since before the dinosaurs, and they didn’t get here by being picky eaters. So clean up every scrap of everything. I like Pine-Sol, it tends to render whatever might be left over unpalatable to them. Your mileage may vary. Again, dig deep into crevices. They’re small, they fit everywhere.

Now seal gaps and cracks. If you don’t like having bugs in your place, then you have to keep them OUT. Caulking works wonders. Great Stuff expanding foam for larger gaps, but be advised: it sticks to everything and it gets bigger after it comes out of the can. Proceed carefully.

Now control the survivors. Baits, poisons, traps. I like to spread Roach Prufe on every flat surface that doesn’t get walked or worked on. It just lies there and waits for an unsuspecting bug to come along. The powder sticks to them, they clean it off, the powder gets inside them and its nature is revealed! It’s boric acid. Good-bye, bug. Diatomaceous earth works wonders, too. I like to mix Roach Prufe with diatomaceous earth, 50-50, and spread it liberally. It is completely inert and won’t hurt you at all. It’s absolute hell on bugs, though.

Commercially available baits help. Find as many different toxins as possible. The more you mix it up, the better. They won’t adapt as well to a many-pronged attack.

Finally, traps. Sticky traps (like «Roach Motel»), like you’d put out for flies. The bug walks onto the trap. and stops. That’s the end of him. Anything further he does, he does standing in one place.

Funny story: I had sticky traps full of bugs and resolved to pick them up the next morning. the next morning comes along and all the sticky traps were empty! Well, nearly. they were full of little legs. It turned out that mice had come along and mowed off all the trapped bugs right at the knees. Very horrorshow, very funny.
