Roaches can do a lot of significant things but mostly negative ones. Roaches in the vicinity of the home could mean poor sanitation which could also imply probability for diseases.

While there are many ways to ward off roaches using commercial roach repellents, these have chemical components that are bad for the health in the long run. But there is a natural way to do so and that is planting some plants that will ward off roaches.

Can roaches destroy soil beds?

While roaches are widely known as indoor pests, they can still destroy soil beds in one way or another.

Since they feed on organic matter, soil beds may be attractive to roaches because of the decaying matter found in organic compost. And when they do feed on them, they take away the nutrients that would supposedly go directly to the plants.

What smell do roaches hate?

Roaches particularly hate strong, concentrated smells and citrus odors like peppermint and eucalyptus.

These smells are so strong for these pests and food hunting would be hard because these scents would disrupt the trail of the scent of the food they would feed on.

Plants that can repel roaches

And now, we are onto the rundown of the eight plants that you can grow to naturally ward off roaches in the home and in the garden (if you are into heavy mulching or compost fertilizing).

1. Bay Leaves
