Plants do not repel bees because of the dependent relationship between plants and bees. Plants are designed to attract bees. Bees are necessary to pollinate plants to ensure that new plants continue to grow.
Wasps are also not repelled by most plants. Wasps need the small insects and worms that live and feed on plants to survive. The artemisia, or wormwood plant, may have a repellent effect on wasps. Wormwood is a shrub that has a natural form of absinthe-containing thujone, a potentially poisonous chemical that is toxic to humans and can also harm other nearby bushes and flowers.
Citronella, eucalyptus and mint are plants that may be wasp repellent when applied to the skin as an essential oil or as oil added to a patio candle. It is possible that, if enough of these plants are grown in one area, they may have a repellent effect on wasps. Citronella is often associated with being a mosquito repellent. It grows in ample sunlight but must be planted as an annual or moved indoors in cold climates. Eucalyptus, native to Australia, can be grown where temperatures stay above 50 degrees Fahrenheit or can be potted for indoors. Mint is hardy in cold zones and grows quickly.
