Flies can be a nuisance both indoors and outdoors. Chemical fly repellents have an unpleasant odour and can contaminate areas where flies are a common problem, such as the kitchen or picnic area. An organic repellent is made from ingredients grown without chemical fertilisers or pesticides. Organic fly repellents lack the smell of chemical repellents and will not leave chemical residues around the house.
Fill a mortar and pestle with organic mint leaves. Crush the leaves with the mortar and pestle so they release their odour. Fill a sachet with the crushed mint and hang it or place it in the fly-infested area.
Sprinkle three to four drops of organic eucalyptus oil on the outside of a sachet and fill the inside with organic eucalyptus leaves. Place the sachet in the area with the fly problem.
Place a pot of organic basil near any pet food containers outside.
