They are known to move around food – which, when combined with the fact that they can potentially contaminate food with bacteria and other disease-causing organisms.
Not only do they land on food, they are also attracted to garbage, feces, and dead animals.
They have a cosmopolitan distribution, meaning they can be found almost anywhere in the world – unfortunately, this includes the UK.
What are fruit flies?
Fruit flies are not the same as house flies or bluebottles – they can be identified by their yellowish-brown color.
They lay their eggs on food (usually rotting fruit). If you accidentally eat their larvae, they can cause constipation, indigestion and diarrhea.
How can I prevent fruit flies from entering my home?
First, it is important to know what fruit flies are attracted to. Fruit flies love the smell and taste of rotting fruit – so it’s likely they’ll congregate around bins and compost.
If you’ve got unprotected fruit that’s starting to close, they’ll target that too. To keep them out of your home, make sure you only have fresh fruit and put food waste outside in the trash.
Fruit flies thrive in dirty conditions – if you keep your surfaces clean and tidy, you’re not giving them an ideal habitat and they’ll likely show up elsewhere.
Keeping your sink clean is paramount. A dirty sink, covered in food particles, presents an ideal breeding ground for fruit flies. Thus, they are also attracted to drains.
A study by University of Kentucky Agrees that the best way to deal with fruit flies is to “eliminate sources of attraction”.
The best ways to catch and get rid of fruit flies
If fruit flies have already successfully infested your home, the first thing you’ll need to do is identify and remove any potential breeding grounds. If you don’t, flies will continue to breed and live in your home, no matter how many of them you kill.
A preferred method of catching and killing fruit flies requires the use of apple cider vinegar, a bowl and some plastic wrap. If you don’t have any apple cider vinegar, beer or wine will suffice.
You’ll need to fill the bowl with your liquid of choice, then seal it with plastic wrap. Make sure the plastic wrap is tight and secure, or it won’t work – if needed, you can put a rubber band around the bowl to hold the plastic in place.
You will then need to make several small holes in the plastic wrap before leaving it near the source of the infection. Fruit flies will be attracted to the smell – upon testing it, they will fly through the holes and not be able to get back out.
This method can also be done using a jar and a piece of paper.
