Fruit flies are small, flying insects that are attracted to ripe fruits and vegetables. They can be a nuisance in homes and gardens, and they can also spread bacteria. There are a number of ways to kill fruit flies in plants, including using traps, sprays, and other methods.
One of the most effective ways to kill fruit flies in plants is to use a trap. There are a number of different types of fruit fly traps available, but one of the simplest and most effective is a vinegar trap. To make a vinegar trap, simply fill a small bowl with apple cider vinegar and cover it with plastic wrap. Poke a few small holes in the plastic wrap, and place the trap near the plants that are being affected by fruit flies.
