How to Get Rid of Housefly Infestations—DIY Fly Control

Nobody Likes Flies.

     Is chasing a fly with a fly swatter part of your regular routine? What’s your weapon of choice—a sandal, a rolled-up newspaper or a fly swatter? Or you may have a cat that likes to hunt the ones she sees and every once in a while she’ll manage to catch one. Flies can be one of the most annoying pests although not usually harmful or terrifying. Wouldn’t it be great if you could just get rid of them? No more waving your hand in front of your face, no more forgetting where you left the fly swatter, and most importantly no more house flies!

Signs of a Housefly Infestation

     The first thing you should know about house flies is that they are a source pest. This means they are attracted to something and once the thing they are attracted to goes away, so will they. The thing everyone knows is that flies are attracted to garbage, if you’ve emptied out the trash and still notice them flying around the trashcans, we recommend cleaning out the trashcan with strong cleaners and water. If your trashcans stink, you may need to use some bleach. You may also want to consider a trashcan with a tight lid as opposed to one without a lid. This will limit the flies’ access to sources of food in the trash and discourage them from breeding inside the container.

     Apart from trash cans, flies can lay eggs in any organic matter. Be sure to toss out dead plants or old fruits and vegetables. Be sure your pets are leaving creating a house fly friendly environment. We’ve heard a story about a pet owner with a fly infestation whose cat had decided to create a second litter box under the sink! Once they got rid of the cat’s “presents,” they noticed the flies disappeared as well.

How to Find Where Flies Are Coming From

     Sometimes if you’re seeing flies inside your home and you can’t find a source inside it’s because the source is actually outside. The first thing we look for when inspecting the exterior of a property with flies is the trash cans. Then we check for fallen fruit and pet droppings. If the fruit and waste is not cleaned up in a timely fashion, flies are attracted to the yard to lay their eggs. When the weather gets warm, the eggs will hatch quicker. It doesn’t take long for flies to hatch and start laying their own eggs. Then all of a sudden you seem to be inundated with flies!

     But how do they come from outside to inside? While it’s possible a fly could slip in while you’re walking through the door, another way they get in is through doors and windows that are left open. If you keep a screen on your doors and windows, that will help keep the flies out. We also recommend checking your screens for any holes.  Flies are tiny and can squeeze into small openings, so if there’s a small hole in the screen, then it’s completely possible for them to get in. They like to live in cooler environments, which is why they will come inside as opposed to staying out in the warm San Diego summer weather.

     House flies can live for up to two months, but they need food to survive for more than three days.  While it is easier for them to eat liquid and sugary particles, they still have the ability to break down solid food crumbs. The diet of the house fly is important if you are trying to create a DIY solution for getting rid of a large number of flies. It’s easy to make your own fly traps.

Mason Jar Fly Trap For Infestations

Follow these steps to get rid of a house flies infestation:

  1. Roll the paper to make a cone funnel that is sized to rest in the opening of your jar while reaching about halfway into the jar without falling in. Once sized for the jar, tape the paper cone together allowing for about a 1 centimeter gap at the apex of the cone. You can cut the paper with scissors to get the opening just right.
  2. Fill the jar less than halfway with 1 part water and 2 parts sugar. Adding a few pieces of fruit, raw meat, or wine can increase the allure of the trap, but will also increase its odor.
  3. Place the cone snugly into the jar without allowing it to touch the liquid and tape it into place.
  4. Find secure, sunny place to set the trap.

Relax and let the flies find your trap.

When it comes to house flies, the most important thing to remember in getting rid of the flies, is to get rid of what they are attracted to. Once you do that, it’s, “Bye-bye fly!”
