Strong Smells and Oils Roaches Hate

Roaches have a very strong sense of smell. They use it to find food and stay away from danger. Some smells are too strong for them. Using these scents can help send roaches packing.

Peppermint Oil

Roaches hate the smell of peppermint. It is a very strong and minty scent. You can mix peppermint oil with water in a spray bottle. Spray it in places where you see roaches, like your kitchen or bathroom. This is a great first step for cockroach prevention tips.

Eucalyptus Oil

Eucalyptus has a fresh, strong smell that roaches do not like. It can confuse them and make them leave. You can put eucalyptus oil in a diffuser to spread the scent. You can also mix it with water and spray it around your house.

Tea Tree Oil

This oil has a very strong smell, like peppermint. Roaches stay away from it. Mix a few drops of tea tree oil with water and a little vinegar. Spray this mixture where roaches might hide, such as under sinks or behind appliances.

Lavender Oil

People love the smell of lavender, but roaches hate it. This nice floral smell is too much for them. You can use lavender essential oils in a spray or put some on cotton balls. Place the cotton balls in cabinets and drawers to keep roaches out.

Citrus Smells

Roaches do not like the smell of citrus fruits like lemons and oranges. You can use the peels to keep them away. Just leave fresh lemon or orange peels in areas where you have seen roaches. The smell is a natural way to tell them to go away. Read our latest post on What Attracts Roaches? How To Get Rid Of Them
