Top Causes of a Fly Infestation: Why Do I Suddenly Have Flies in My House?

Have you ever wondered why there are so many flies in your house? One minute your house is fly-free, and the very next moment flies are buzzing about. As house flies often come from unsanitary places, they will transfer whatever they have landed on previously to your things, which can be very frustrating and even dangerous.

The average housefly is one of the most common pests infesting homes. Few obstacles can stop them from coming inside when they find something they like in a home. It is normal for a couple of flies to wander into your home every now and then, but when they come in large numbers, you should be concerned.

With the help of expert techniques and professional fly control products, we will show you how flies get inside of your house and how you can get rid of them.

Why Do I Suddenly Have Flies in My House?

An adult house fly lives for about 15 to 30 days. Sometimes, it seems like removing house flies from your home is hardly worthwhile since they have about a month to live, and they are going to die anyway.

Unfortunately, this is not the case. During the period that an adult fly lives, it continues to produce eggs every day, so that they can be replaced in a very short time. While you keep hoping the flies will die, they will keep growing and, soon enough, your entire home will be infested.

The most problematic thing about houseflies is that they breed as long as they live. It can lay between 150 and 200 eggs at a time and about 5 to 6 times throughout its life. That means a single fly in your house can multiply more than 100 times. What you see as just a little innocent creature can multiply at the speed of light.

Where Do Flies Come From?

Most likely, flies come from two types of sources:  

Protein-based

  • Animal faeces (Maybe you or a neighbour don’t pick them up as regularly as you should?)
  • Dead animals (Maybe a mouse or rat somewhere in the house?)
  • Food scraps (perhaps trash cans aren’t taken out of the house or are stored too close to the house outside?)

Moisture based

  • Plumbing issues (Have you noticed any leaky pipes under or outside your property?)
  • Overwatering (Houseplants or lawns being overwatered can lead to fly infestations)
