What Attracts Fruit Flies?
Typically, you can find fruit flies near ripe, overripe, or decaying fruit, hence their name. Anything in the process of fermentation may be appealing to fruit flies.
The two biggest attractors of fruit flies are fruit bowls or fruit trees in or near your home.
Bowls of fruit: If you have a bowl of fruit that’s overripe or decaying, it’s likely attracting fruit flies. Unless you cover the bowl with a towel or plastic film, fruit flies will always be able to sniff out your afternoon snacks. Fruit in the fridge is safe since it’s sealed and too cold for them to survive in.
Fruit trees: With fruit trees, your best bet is to maintain regular groundskeeping, including the disposal of fallen or rotten fruit lying near the tree. Fallen fruit can also attract rodents and other small pests.
How Often do Fruit Flies Reproduce?
In ideal conditions, adult fruit flies can live for up to 30 days, giving them plenty of time to reproduce and take over a habitat (such as your kitchen or backyard). A single female fruit fly has the potential to lay over 500 eggs in its lifetime. If you let a handful of flies go untouched, you could quickly be dealing with thousands in just over a week.
Fruit flies feed near where they lay their eggs and once the eggs hatch, the fruit fly larvae continue to eat near where they hatch until they mature to adulthood. You could have an infestation growing in your home without noticing until it extends beyond control.
Though near the source of food is an ideal breeding ground, fruit flies will also lay eggs near:
- Stagnant water such as drain pipes or gutters.
- Under kitchen bathroom cabinets with water sitting in them, leaky sink drains, or near garbage disposals.
- Trash cans with lots of rotten food or spilled fruit juice.
- An open wine bottle or liquor with high sugar content.
- Compost piles or containers, especially ones that are sitting for a while.
- Fruit that’s decayed internally but appears fine externally and brought into a home.
