Lavender plants are not sought out by bugs, rabbits, or other creatures because of their unique fragrance due to the essential oils on their leaves.
These simple-to-grow blooms also deter mosquitos. Marigolds are rich in insecticidal constituents, which are insect-repelling compounds. This is one reason gardeners and landscapers love them.
The Brooklyn Botanical Garden recommends lemon-scented plants such as citronella grass and lemongrass to repel mosquitos, and the live plant is the best way to keep those bugs at bay.
