However, it is important to note that increasing the concentration to 30 parts per 100 reduced the repellent effect slightly to 96.5%. Nevertheless, oregano oil still proved to be a formidable roach repellent across different concentrations.

Rosemary Oil Causes Roach Mortality Upon Contact

Rosemary essential oil is an even more effective and aggressive repellent against roaches compared to oregano essential oil. In fact, a study has shown that rosemary oil is toxic to roaches and can lead to their death upon contact. This means that not only do roaches avoid rosemary oil, but it can also eliminate them.

The study conducted on rosemary oil examined various concentrations, ranging from 2.5 to 30 parts per 100. Surprisingly, all concentrations resulted in roach mortality.

Effective Alternatives To Spraying Neat Essential Oil
