Cockroaches are especially afraid of strong scents.

Citrus, peppermint, and other strong smells are thought to be repellants for cockroaches.

You can use these scents to keep cockroaches away from your home by using essential oils, scented candles, and sprays.

Cockroaches are also scared of bright lights.

Turning on the lights or using a flashlight is a great way to scare cockroaches away.

Additionally, cockroaches are also scared of loud noises and vibrations, so tapping or making loud noises can help make them flee.

Finally, cockroaches are scared of tight spaces and small places.

This means that leaving out traps, closing off cracks and crevices, and sealing off any other small areas can help keep cockroaches away from your home.

In conclusion, cockroaches are afraid of strong smells, bright lights, loud noises and vibrations, and tight spaces.

Knowing what cockroaches are afraid of can help you better protect your home from these pesky pests.

Strong Smells

Cockroaches have an incredibly powerful sense of smell, which means they can be easily scared off by certain strong odors.

Citrus, peppermint, and chemical sprays are all known to be effective deterrents against cockroaches.

Citrus scents like lemon, lime, or orange can be used in the form of essential oils, as well as in natural cleaning products.

Peppermint also helps to repel cockroaches, as its strong scent is unpleasant to them.

As for chemical sprays, these can typically be found at your local hardware store and should be used as directed.

Although these strong smells are effective against cockroaches, it is important to use them in moderation, as too much of a scent can be overwhelming for both humans and cockroaches.

Bright Lights

Cockroaches are most certainly afraid of bright lights.

In fact, they will usually scatter and flee when exposed to a bright light source.

This could be a flashlight, a lamp, or even the sun.

This reaction to light is especially true of the species of cockroaches that are most common in homes.

These species usually hide away during the day, and come out at night when it is dark.

When exposed to bright light, they are shocked and quickly scurry away to find a dark place to hide.

This is why it is often recommended to use a flashlight to search for cockroaches in the home they will usually scatter and become easier to spot.

Additionally, it is important to make sure the home is well-lit to prevent cockroaches from taking up residence.

Keeping lights on, especially in dark places like closets, can help keep cockroaches away.

Of course, it is important to remember that cockroaches are not afraid of all light.

Low light levels, such as those seen in the evening or at night, are often comfortable for them.

It is only when they are exposed to bright light that they will flee and scatter.

So, if youre trying to keep them away, make sure youre using a bright light source.


Cockroaches are not a fan of vibrations and loud noises.

They are easily startled by unexpected sound and vibration, making them scurry away to hide.

To use this to your advantage, you can use loud noises or tapping to try and scare them off.

This can be done by clapping your hands or banging on the floor, walls, or furniture.

This will create vibrations that will cause the cockroaches to flee.

You can also use devices such as ultrasonic pest repellers, which emit high-frequency sound waves that are unpleasant to cockroaches.

This sound can’t be heard by humans, so it won’t bother you, but it will make the cockroaches uncomfortable enough to flee.

Finally, if you live in an apartment complex, you can talk to your landlord about installing vibration dampeners in the walls.

This will help prevent vibrations from traveling through the walls, which can also help keep cockroaches away.

Tight Spaces

When it comes to what cockroaches are afraid of, tight spaces definitely make the list.

This is because cockroaches are highly adapted to their environment and prefer to be able to move freely.

When faced with tight spaces, they are unable to maneuver and become stressed, causing them to search for a way out.

To keep cockroaches away, homeowners can use traps or block off cracks and crevices with caulk or other materials.

Traps provide a tight space that cockroaches cant escape from, and they can be used to catch and dispose of the pests.

Additionally, cracks and crevices are common areas for cockroaches to enter the home, so taking steps to seal them off can help prevent them from entering in the first place.

In addition to traps and sealing off entry points, home owners can also use sticky boards to catch and contain cockroaches.

Sticky boards are sheets of paper with a sticky substance on one side, and when placed in areas where cockroaches are likely to travel, they can trap and contain the pests.

Finally, homeowners can also use cockroach baits to keep cockroaches away.

Cockroach baits contain a slow-acting poison that cockroaches will feed on, and when the poison takes effect, they will die.

Baits should be placed in areas where cockroaches are likely to travel, such as behind appliances or under furniture.

Overall, tight spaces are one of the things that cockroaches are afraid of.

Taking steps to seal entry points and using traps, sticky boards, and baits can help keep cockroaches away and prevent them from entering the home.

Traps and Crevices

Cockroaches are afraid of tight spaces, and leaving out traps or closing off cracks and crevices can help keep them away.

Traps are a great way to catch and kill cockroaches that are already in the home.

Traps come in various sizes and shapes, and are usually baited with food.

The cockroach will be attracted to the food, and when it enters the trap, it will get stuck and eventually die.

Traps are most effective when placed in areas where cockroaches are known to be active.

In addition to traps, closing off cracks and crevices can help prevent cockroaches from entering the home in the first place.

Cockroaches can squeeze through even the smallest of spaces, so its important to seal any cracks and crevices around windows, doors, and pipes.

Any openings or holes should be caulked or sealed with silicone caulk.

Additionally, its important to inspect the home regularly for any signs of cockroach activity, such as droppings or egg cases, and to take immediate action.

Finally, its important to remember that traps and crevice sealing alone will not completely eliminate a cockroach infestation.

Its important to take a comprehensive approach to cockroach control, such as using insecticides and reducing food sources.

Additionally, regular cleaning and vacuuming can help reduce the number of cockroaches in the home.

Additional Tips for Keeping Cockroaches Away

When it comes to keeping cockroaches away, there are a few additional tips that can help.

First, it is important to keep your home clean.

Cockroaches are attracted to food, so make sure to wipe up any spills and crumbs, and store food in airtight containers.

Additionally, make sure to vacuum and sweep regularly to eliminate any potential hiding spots.

In addition to keeping your home clean, it is important to seal up any cracks and crevices in your walls and floors.

Cockroaches can squeeze through the smallest of openings, so it is important to make sure that any potential entry points are completely sealed off.

Furthermore, sealing off your windows and doors with caulk or weatherstripping can also help keep these pests away.

Finally, it is important to use chemical sprays and other pest control products to keep cockroaches away.

Insecticides and other products designed for pest control can be used to create barriers that cockroaches cannot cross.

Additionally, these products can be used to kill any cockroaches that may already be living in your home.

It is important to follow the directions on the label when using any pest control products, and to use them only as directed.
