What Causes Flies To Stay In Your Garage?

Here lie the majority of the answers you are looking for. If you can track down the roots of flies in your garage, it will be much easier to eliminate them.

They Come for Food

The first thing flies look for around food to food. Any open source of food, the smell of rotten things will attract them. They like to eat feces, rotten food waste, meat, ripe fruits and vegetables, and bad-smelling drinks, such as alcohol, soda, and so on.

We sometimes store our garbage inside the garage, which is one of the leading causes of fly infestation. Another reason could be leaving the leftover food inside the garage. Leaking sewerage or draining pipes can be responsible in this case.

Your Garage Might Be A Safe Place For Them

After food, come two important factors that can attract flies in your garage: breeding and living. Normally most garages are not given the proper attention they require when it comes to cleaning. All the stored items and furniture make our garage an ideal place for them to live safely.

Besides, there is a lack of airflow and public interaction inside a garage. The environment is mostly humid and warm, making it ideal for the breeding of house flies.

How Can You Detect Fly Infestation?

Unless you spot flies buzzing around you, it will be hard for you to detect their existence. And all of a sudden, you’ll notice a burst of flies inside your garage. That’s why it’s important to be able to detect a fly infestation.

There are three main signs of fly infestation: They are:

  • Small Clusters: If you notice small black clusters in the corners, mainly over the lighter areas, it can be an early sign of fly infestation. Keep a close eye on them to see whether they are growing.
  • Regular Sighting: This one is pretty obvious. If you have noticed flies flying around for more than two or three days, then you can be sure that there will be many more.
  • Maggots: After the eggs of the flies are hatched, the larvae are called maggots. Maggots call for immediate action. You should also take preventive action at this stage. 

How To Kill Flies In Your Garage?

There are many options available to kill flies. Here are some of our recommended methods.

1) Use Sticky Traps To Kill Flies

2) Fly Baits Work Well

In an enclosed garage, fly baits can help you eliminate the flies. But the problem with them is that they are poisonous and risky for children and pets.

Take an aluminum or plastic pan and put a quarter of bait in it. Keep it at a height that children or pets can’t reach. The bait will attract the flies and kill them eventually. Once done, don’t forget to seal it up properly and dispose of it.

3) Kill Flies With A Fly Swatter

Swatters are the easiest way to kill visible flies. The traditional swatter can be used on flies that are sitting idle on a surface or on Rechargeable swatter rackets to kill flying flies immediately.

Keep The Surrounding Clean

It is not necessary that the breeding place be inside your garage. Always keep the grass short around the garage and remove anything that can attract flies. Destroy the potential breeding grounds.

How To Prevent Flies From Entering Your Garage?
