There are several sprays that can be used to kill fruit flies. Here are some options:

• Insecticide fogs: CB80 or PT 565 Pyrethrum Aerosol can be sprayed into the air to kill adult winged fruit flies.

• Lemongrass oil spray: In a small spray bottle, add 2 ounces of hot water and 10 drops of lemongrass essential oil. This homemade spray can be used to kill fruit flies.

Its worth noting that there are also several non-spray methods for getting rid of fruit flies, such as using traps or natural scents to deter them. For example, herbal tea bags, cotton balls with essential oils, and sachets of dried herbs can be effective in deterring fruit flies. Additionally, a homemade trap can be made by pouring apple cider vinegar into a glass and covering the opening with plastic wrap and a rubber band, then poking small holes into the plastic cover for the fruit flies to enter.
