No, flies do not like bleach; its strong chemical smell and properties act as a deterrent and it can kill them, but pouring it down drains is often ineffective for breeding pests like drain flies because it doesn't fully clear the organic film where they lay eggs, and it's risky for pipes and septic systems. Bleach works by sanitizing surfaces, indirectly discouraging pests, but specialized cleaners or physical removal are better for eliminating breeding grounds.
While this chemical might get rid of some larvae, bleach passes quickly down the drain and does not penetrate the thick build-up where eggs are deposited by the female drain fly and larvae live. As a result, in most cases, bleach does not get rid of drain flies.
Flies hate strong, pungent smells, especially essential oils like lavender, eucalyptus, peppermint, and lemongrass, due to compounds like linalool that overwhelm their senses; other scents they dislike include strong herbs like basil and rosemary, and even things like cinnamon and citronella. These natural scents can be used in diffusers, sprays, or by planting them to create a fly-free zone, as flies prefer filth and are repelled by these clean, sharp aromas.
The fastest ways to kill flies involve insecticide sprays (killing in seconds), electric fly swatters (instant electrocution), or a DIY mix of apple cider vinegar and dish soap in a trap (flies get trapped and drown quickly). For a quick, low-mess kill on a landed fly, a spray bottle with water and a few drops of dish soap also works by breaking surface tension, making wings useless.
Bleach's strong odor and chemical makeup can act as a deterrent, but it does not inherently kill or repel insects. Its primary role in bug control is its ability to sanitize surfaces and eliminate attractants, thus indirectly discouraging insect infestation.
Bed bugs are not attracted to bleach and will avoid it at all costs, which makes direct contact difficult.
While it can kill adult flies on contact, it is unlikely to eradicate an infestation. Bleach might kill the surface level of the problem, but if you do not penetrate the deeper part where the eggs are, the problem will continue.
Several factors can contribute to a sudden increase in flies in your home: Decaying organic matter: Flies are attracted to rotting food, garbage, and other decomposing materials. These substances serve as ideal breeding grounds, quickly leading to infestations.
September's daytime temperatures usually sit in the 70s and 80s, with cooler nights in the 50s and 60s. These mild conditions are perfect for flies to reproduce quickly without the stress of extreme heat. Add in the humidity from late-summer thunderstorms, and you have moist environments ideal for fly eggs and larvae.
To quickly get rid of flies, set up apple cider vinegar traps (vinegar, sugar, dish soap in a jar with holes) for attraction and drowning, use sticky flypaper, or spray them with a dish soap & water solution, but the fastest method is cleaning up their attractants: seal garbage, clean spills, and store food airtight, as eliminating breeding grounds stops the problem at its source.
Sense of smell
Leaving food uncovered, or allowing it to emit strong scents, functions like an open invitation to flies in your area. Chemical signals. Various foods release chemical compounds that mimic the scent of ripe fruits, or decaying organic matter– both of which naturally attract flies.
Take vinegar, liquid dishwashing soap, sugar in a bowl. Cover it with plastic film, poke a few holes and leave it near the fruits, on your dining table or the kitchen slab. Watch the fruit flies fall in the trap that they will never be able to escape!
“While it's more widely known for repelling mosquitoes, catnip can also help deter flies when used in oil form or planted around your home,” she says. Other scents that could help banish flies and other insects include rosemary, lemongrass, cloves, and citronella.
Bleach may not even be all that effective for drain flies because it flows too quickly. There is not enough time for it to break through thick buildups of drain fly eggs and larvae.

Mix 10-20 drops of tea tree, eucalyptus, or lavender oil with 2 cups of water. Pour down drains or spray nearby areas. These oils repel flies naturally.
A fly infestation can last from a week to several months, depending on the species, environmental conditions, and if you eliminate breeding sources. While a single adult fly's life cycle (egg to adult) might finish in 1-3 weeks, a persistent infestation comes from continuous breeding in hidden organic matter, so eliminating food/breeding sites is key to ending it quickly, often within 7-10 days of cleaning up, but it can linger if sources aren't found.
An annoying fall invader of homes, cluster fly adults are now on the move, looking for a warm spot to overwinter. As the days grow shorter and the night temperatures drop, a number of insects begin looking for their winter's lodging. These are insects that overwinter as adults.
Black flies seem to be most abundant on hot, humid spring days but are typically common throughout this mid-May to late June flight period.
Flies lay eggs in moist, organic material such as rotting food, animal waste, or damp compost. These eggs are tiny, white, and hard to see. Within a day or two, the eggs hatch into larvae, or maggots. You might find clusters of eggs in garbage bins, underneath appliances, or inside drains.
Fill a disposable container with water, sugar, dish soap, and a few tablespoons of apple cider vinegar. Stir the sugar water solution together, then place it near a fly-infested area. The flies will be attracted to the solution and drown as soon as they touch the water. Repeat this process until all the flies are gone.
Drain flies thrive in stagnant and standing water. Common sources include slow or clogged drains, rarely used and unused toilets, refrigerator drain pans, and standing water created by leaking pipes. They typically enter buildings through basements, windows, and drains.
The DRAIN FLY (Psychodidae) also known as: Sewer fly, sink fly, filter flies, sewer gnats. -They are considered 'true flies'. Often confused with fungus gnats and fruit flies. They breed and lay eggs in Aqueous environments like drains, standing water and pipes.
To combat this, Pestline pest control recommends first preventing flies from gathering by keeping your home and patio free of debris. Then, supplement efforts by using a natural fly repellant: Fill a spray bottle with ⅓ hydrogen peroxide and ⅔ water.
