Decaying matter is one of the most common causes of a fly
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 that is available to them.
Different flies have different breeding sites, but examining your compost, garbage cans, uncovered fruit or produce, and drains for maggots is a good place to start.
Keep in mind that flies feed on and lay eggs in anything that is rotting or putrefying. The likely breeding sites for house fly larvae indoors include animal carcasses, large numbers of dead insects, rotting meat or produce.
Depending on the type of fly you are facing, they can spend a week, going up to 4 weeks in your home. Some flies can overwinter in your home as well, reducing their daily activities to almost zero, and last up to a year indoors.
Therefore, if you find that you suddenly have a lot of flies in your house, chances are there's decaying matter somewhere. No matter how clean you keep your house, you probably have something rotting somewhere. For example, garbage cans and garbage disposals. These spots are prime breeding sites for flies.
Through Cracks and Crevices
You may not think much about cracks or open spaces in the window sills or walls, but flies and other bugs will jump at the opportunity to make their way through these little spaces. They can also find their way in through the vents in your home!
Mint, lavender and marigold – plant these in your garden and have pots in your house to deter them from entering your property before they even make it to the front door! Cinnamon – use cinnamon as an air freshner, as flies hate the smell!
First, check your screens and windows for holes, and remind your family to close the door behind them. Then, make sure your house is clean. House flies are attracted to things that make you go "ew," like pet waste, drain gunk (especially if you have a garbage disposal), overripe produce, trash cans, and sticky spills.
The black or brown flies/moths you see in your drain are most likely “drain flies” that live on decomposing, organic matter in your drains, which explains why they hang out near sinks or showers. These flies are also referred to as: Moth flies.
A mixture of apple cider vinegar and dish soap can help you trap flies and kill them. Mix about an inch of apple cider vinegar and a few drops of dish soap in a tall glass. Cover the glass with plastic wrap, secure it with a rubber band and poke small holes in the top.
Choose from either chemical sprays, household cleaners, or hairspray. Chemical sprays kill flies instantly upon contact, though they contain harsh chemicals. You can also spray the flies with household cleaners, like Windex or Formula 409, or with an aerosol like hairspray. All of these sprays will help you kill a fly.
Stock up on essential oils that flies don't like (including lavender, eucalyptus, peppermint, lemongrass, and basil),1 and use them to make your own fly repellent spray. To mix, just fill a spray bottle with water, and add enough essential oil to fragrance.
Sometimes there is something attracting them close to your window or door on the outside, and they make their way in,' he says. This could be as simple as some garbage in the can near your window or some cracks in your drainpipe. 'Some flies like drain flies can enter through hairline cracks in a drain pipe.
House flies typically lay eggs on animal feces and garbage. White, legless maggots (the larval stage) hatch from the eggs and grow to about ½ inch.
For the most part, flies are attracted to windows for warmth. And, once they get to the window, they simply get confused as they fly around trying to find a food source. You may have a housefly problem outside because flies will sleep in plants, fence wires, garbage cans, and on the ground.
Flies lay their eggs near to the food sources
Some of the best spots for many flies to go is including your kitchen garbage bin and dirty drains. Your garbage bin is always filled with smelly and rotting daily food waste that often become the reasons for so many flies inside your house.
Small dark clusters of spots (the size of a pinhead) – Look in light fittings, upper areas of the room and wall surfaces. Check areas that are difficult to clean thoroughly such as drainage channels, drains and sub-floor cavities where the contents of broken drains may be accumulating.
Will Flies Go Away On Their Own? One housefly on its own will eventually die of natural causes, stress, or lack of resources. However, if you are researching the lifespan of flies, we doubt you have seen just one inside your home.
Employ a simple all-natural homemade fly trap to lure and imprison unwanted insects. All it takes is a plastic container, plastic wrap, and fly bait (like fruit, vinegar, or apple cider vinegar). Set up the fly trap in a corner to attract and confine flies, then dispose of them when you've won the battle.
If there's decaying matter around your home, it is very unlikely they will go independently. You have to take care of the situation. If you want flies to go away, you have to eliminate them first and put pest control measures in place to make sure they don't come back.
Eucalyptus oil is a good option, but you can also use lavender, citrus, pine, clove, peppermint, and thyme essential oils. Most flies hate these scents, so the oils will act as a fly repellent.
Vinegar attracts, not repels flies; however, a container with vinegar and dish soap will function as an attractant trap as the vinegar lures flies to enter the trap and the dish soap will cause the flies to sink and die.
