Cockroaches are well known for their bad smell. Some even say the stink is worse than that of rotten eggs.

However, not all roaches smell the same. Some cockroaches actually smell bad to others, and dislike certain smells.

In other words, roaches don’t like the smell of citrus or vinegar.

What Smell Do Roaches Hate?

Roaches are known for being pests that can infest your home, making it messy and smelly.

Research done by the University of Florida found that roaches are repelled by the smell of peppermint and lavender.

The study was carried out on German roaches, but the results may apply to other kinds too.

The researchers found that roaches avoid peppermint because of the menthol it contains while lavender is avoided because of linalool.

The roaches were more sensitive to linalool and menthol than humans, so the researchers concluded that these chemicals could be used as natural repellents.

The researchers found peppermint and lavender to be more effective than commercial roach repellents, which were contaminated by mold and bacteria.

Essential oils are safe to use indoors, but store-bought traps may contain harmful ingredients that can damage your health.

While peppermint and lavender work against roaches, these essential oils should not be used as substitutes for pest-control products.

You can also use essential oils as air fresheners, or in diffusers to help get rid of indoor odors.

You can even use them to help get rid of sweat stains from clothes, or to repel insects away from your home and yard.

Why Do Cockroaches Hate Certain Smells?

Cockroaches can detect the scent of a chemical called isopentyl acetate in food containers such as ice cream buckets.

Cockroaches and palmetto bugs also detect carbon dioxide released when food is being processed.

Although essential oils have been proven to be effective against many insects, they may not be able to completely get rid of a cockroach infestation.

How Long Will These Smells Repel Cockroaches?

If there is an existing infestation in your home, it may take some time until these scents can completely eliminate the roaches.

However, using essential oils as air fresheners may keep them away until the infestation is completely exterminated.

In addition, the odors may linger in the home for some time after the infestation has been eliminated, so you should try to avoid using musky-scented chemicals in your home.

While essential oils may effectively repel cockroaches, other remedies for getting rid of them include removing food and water sources from the home, sealing cracks that let in moisture, and eliminating clutter to keep the pests from hiding in the nooks and crannies of your home.

Cockroaches may avoid the area where scents are used since the smell of these oils is unpleasant to them.
