Fly repellent plants are natural alternatives to the slightly more invasive fly sprays and traps, which are usually used to get rid of the annoying and potentially dangerous flies. While fly sprays employ toxic chemicals and traps rely on smelly baits to lure flies, plants repel flies using their innate fragrance from leaves, bark, and (or) flowers – a pleasant way to keep the home exteriors free of flies.
The effectiveness of fly repellent plants is still debatable, as there is no scientific evidence to prove the concept. However, age-old practices have revealed that select plants, flowers, herbs and scented grasses serve as strong retardants to insects, even proving fatal when used as baits.
There are several types of flies, ranging from the common housefly and fruit fly to other varieties that plague the garden and destroy vegetable crops. Flowering plants that deter flies include but certainly are not limited to Shoofly, Marigold, Gold Leaf Tansy, Nasturtium, Rue, Wormwood variants, English Lavender, Mountain Tobacco, and the ornamental Kentucky coffee tree.
Many common herbs used in the kitchen or for aromatic therapy work equally well in repelling flies. Basil, Mint, Rosemary, Lemon Basil, Penny Royal, Eucalyptus, Sage and Thyme help keep select types of flies and other insects away from the gardens that border homes and offices.
Irrespective of the size of a garden, grass patches make a wonderful addition to the landscape and also act as fly repellants. Lining pathways or seating zones with lemon grass or citronella offer natural respite from buzzing flies. Leeks, onions and lettuce in the kitchen garden are known to ward off flies from affecting other nearby plants.
A neat blend of looks and utility, carnivorous plants such as Venus fly trap lure insects with their bright colours. Some of these plants are readily available and are easy to care for, making them ideal to capture that odd fly looking to get indoors. The choice of fly repellent plants depends on the type of the pest, extent of infestation and the local climate.
