How to get rid of Houseflies?

We’re all familiar with your standard housefly, the one that comes in through an open door or window and then can’t figure out how to exit the same way. They might not have entered your home by accident but instead be entering to look for a place to lay their eggs. 

The standard lifecycle of a housefly is, they begin as an egg and then after one day develop into larva, then pupa and finally full-grown adults. This full cycle can take between 7 to 10 days to complete. The overall lifespan of a housefly is 3 months and the most worrying number of all is that adult females can lay up to 900 eggs in her lifetime. So with that in mind it’s best to stop the flies coming in, otherwise you could have a full infestation in a matter of weeks.

If left to go untreated, fruit flies in your home could cause potential health risks. Like many other flies, they have the potential to pick up and carry bacteria. Don’t let their name fool you, these little pests are particularly drawn to manure and other faecal matter that contain bacteria such as E.coli. So when they visit your home and land on your fresh produce, they leave behind traces of this.

That’s not all, after mating, female fruit flies inject batches of eggs into fresh fruit which then contaminates it.

How to prevent fruit flies from entering my home?

As in most cases with pests, the best way to prevent the fruit fly is to make sure that your home's common areas are kept clean. 

  • Wipe down any surfaces that come into contact with food
  • Check your indoor garbage bins and regularly empty and wipe down with a heavy duty cleaner 
  • If you notice them around your sink, check that the drain is not clogged. Regularly check and clean as fruit flies like to live and breed in warm, damp places.

Why not try out some of these useful household methods for preventing an infestation, firstly we have some easy to construct homemade traps - 

Rotten food trap: Rather than tossing out rotten or left over food, place in a disposable container and cover with plastic wrap. Poke a few holes in the wrap and place in a high density area. The flies should swarm inside and become trapped, once dead dispose of the container and repeat until all flies are gone.

Red wine trap: If you don’t plan on finishing your glass or bottle, do not pour it away, instead place it in a disposable container and mix with dish detergent, again cover with plastic wrap and poke holes big enough for the flies to crawl inside. The wine will attract the flies and the detergent will make it difficult for them to escape which will drown the flies. Again dispose of and repeat until all flies are gone from your home. 

Vinegar solution trap: Using a disposable container, fill with water and add a few tablespoons of vinegar, sugar and a few drops of dish soap then stir. Place near a swarm and wait for the flies to be attracted to the solution where they will drown once they touch the water. Again continue until all flies are gone. 

Store bought sticky traps work here as well.
