5 Reasons Your House is Infested with So Many House Flies

Have you been wondering, "Why are there so many flies in my house?" One moment, your house is fly-free, and the very next moment, flies seem to come out of nowhere to fly and buzz around. This can be frustrating and even a health hazard since house flies often come from unsanitary places and will transfer what they have landed on to your things.

Flies, like the average house fly, are one of the most common bugs that infest homes. When they find something they like in a home, few obstacles can stop them from finding a way indoors. A fly or two flying their way inside may be normal and an easy issue to handle, but when they appear in your home in large numbers, that's when you should be concerned.

In this article, we will cover how flies get in the house and what you can do to get rid of the infestation by using expert techniques and professional fly control products.

You Get Deceived by Their Short Lifespan

An adult house fly has a lifespan of about 15 to 30 days. Sometimes, it feels like there’s hardly any point in taking measures to remove house flies from your home when they only have about a month to live, and they will die in that time automatically.

However, that is never the case. When an adult fly survives, it continues to breed every day, leaving behind eggs that can replace it in a very short period. While you keep hoping they will die, flies will keep on growing, and before you know it, your whole place is covered with these awful creatures.

An Adult House Fly Can Breed Quickly

The worst feature of a house fly is that it breeds as long as it lives. It can lay about 150 eggs at a time and can lay eggs 5 to 6 times during its entire life. This means that one fly can multiply over 100 times in your home. What you see as just an innocent little creature can multiply at the speed of a bullet.

Warm Places Help Them Survive

The eggs that an adult fly lays have specific conditions in which they survive and grow into a larva. Generally, warm conditions, such as a temperature of 75 degrees or more, are quite favorable for these flies to grow.

When you notice a growing number of flies in your home, you need to control the temperature to prevent them from multiplying while they are still in the hatching stage. Once they have grown into adult flies, you cannot stop them other than kill them.  

Any Amount of Rotten Matter Can be a Conducive Environment

The house fly adult lays eggs in filth, and the larva grows into a pupa, an older stage of the flies, around rotting things. Therefore, if you have a garbage can near the door, if your garbage disposal unit is leaking, or if you have some other issues that are polluting your home, you need to look into that seriously.

A foul rotting piece of organic matter (from food to feces and everything in between) is probably the reason why the house flies are growing at an alarming rate in your home. It is the perfect breeding ground for houseflies, and they will show up near and far to take advantage of the filth available.

You are Not Doing Enough to Keep them Out

You must take more steps to keep the flies out once they enter your house. To get rid of them completely, you must employ tools to kill adult flies and ensure they don’t have much time to breed and lay eggs in the house. Take appropriate preventive steps to keep the already laid eggs from growing into adult flies.

How To Get Rid of A Fly Infestation

If you are fed up with house flies in your home, you need to spring into action to eliminate the problem. Finding the rotting food source is half the battle in getting rid of house flies because once the filth is located, discarded, and the area is cleaned up, most house flies will leave the premises. You will need to use professional quality fly control products for the ones that linger around.

Fly control usually takes multiple treatment methods and techniques to eliminate the house flies. We recommend a combination of pesticides (like Pyrid Aerosol) and traps (like Musca-Stik) to capture and kill the straggler house flies.

Step 1 - Properly Sanitize Your Home

Detailed sanitation is the key to house fly control for commercial structures, homeowners, and property management companies. Remove the rotting food source, the breeding areas, and the odors that attract them, and you will be well on your way to having fewer fly infestations in your house.

• Keep trash sealed with tight lids and ensure that exclusion measures are in place to prevent the flies from entering the structures. (Screens on doors and windows, sealing the cracks, and repairing any openings are very important when it comes to fly control.)
• Take out the trash regularly, and do not let garbage pile up.
• Pick up pet feces outside and remove any carcasses from dead rodents or food lying around to prevent flies from hovering around these filth sources to eat and lay eggs.
• Wipe down counters, mop floors, and toss out any rotting or spoiled food on your counter or in the fridge.

Step 2 - Use Musca-Stik To Trap Lingering House Flies

While most flies will leave after the home has been properly sanitized, some will stick around and look for food or other breeding sources. This is when a trap like Musca-Stik comes in handy. Musca-Stik Traps are affordable, pesticide-free traps that utilize pheromones and a visual attractant to lure House Flies directly to the trap, which is full of glue. House flies captured by the Musca-Stik Trap will be unable to escape and will eventually die.

To use, pour the accompanying pheromone packet into the catch basin at the end of the trap and then hang the trap in an area where House Flies have been active. Flies that are still in your home will be lured by the bright orange color of the Musca-Stik trap and the pheromones and will be captured quickly.

Step 3 - Spray Pyrid Aerosol

In addition to trapping flies that are getting into your home, we recommend using Pyrid Aerosol. This is a pyrethrum-based aerosol spray that can kill flies on contact.

Shake the can well and then point and spray any House Fly you locate inside or around your house to incapacitate them quickly. Pyrid Aerosol should be applied at the rate of 1 to 3 seconds per 1,000 cubic feet.

If spraying in the kitchen, make sure that no food items are out and uncovered. Do not let people or pets enter areas treated until 15 minutes have gone by and the rooms have been ventilated. If spraying in the kitchen, wipe the countertops and food serving surfaces clean after treatment.

Key Takeaways

Why are there so many flies in my House?

• House flies get into your house for reasons like rotten matter, excessive warmth, and breeding grounds that your home may offer.
• House flies can multiply into hundreds within a couple of days in your home. You must kill the existing flies to stop them from breeding and keep the growing ones from developing into an adult fly.

How to Get Rid of Invading Houseflies

• Proper sanitation and removal of filth/breeding sources are half the battle to get rid of invading houseflies that are entering your house.
• Treat remaining house flies with a combination of traps like Musca-Stik and an effective insecticide like Pyrid Aerosol.
