Sweet basil

Grow this excellent mosquito repellent as a centrepiece on your patio table, or plant a drift of basil in the garden bed.


Rodents will also be far away with the help of a plant. Mint varieties, such as peppermint, can deter rodents in your home.


A form of mint, pennyroyal (Mentha pulegium) can be grown as herbal ‘lawn’ in a sunny to lightly shaded spot. The leaves exude a pleasant minty scent and are repellent to fleas and mosquitoes.


Not only is rosemary a fantastic herb in your favourite lamb dishes. But its strong scent can override the aroma of other plants, which confuses and deters insects such as the carrot fly, whitefly, moths and even silverfish.
