Why does Rosemary repel Bed-Bugs?

Rosemary repels bed bugs primarily due to its strong scent, which contains compounds like camphor and 1,8-cineole that are unappealing to these pests. These natural oils disrupt the bugs' ability to detect carbon dioxide and other cues that attract them to hosts. Additionally, the antimicrobial properties of rosemary can create an inhospitable environment for bed bugs, further discouraging their presence. Using rosemary as a repellent can be part of a broader strategy for pest control.
