“When it comes to using eucalyptus to repel rats, the plant’s oils are the real star of the show,” Zack wrote.
“While the entire tree contains eucalyptol, it isn’t really feasible or practical to use the leaves or bark as a rat repellent.
“Plus, the oils have the highest concentration of eucalyptol making them the most effective against rodents.”
Eucalyptus oil that’s 100% pure can be found in Holland and Barrett for as little as £5.
