Battling Phorid Flies: Will Bleach Kill Phorid Flies?

will bleach kill phorid flies

Are you grappling with the relentless buzz of phorid flies in your home and wondering, will bleach kill phorid flies? These tiny, persistent pests, often found scuttling around kitchen sinks and bathrooms, can be a source of significant annoyance. Many homeowners reach for bleach, a common household disinfectant, in hopes of finding an easy solution. 

This article delves into the effectiveness of bleach against these pesky invaders. We’ll explore not only the immediate impact of bleach on phorid flies but also consider the broader picture of managing and preventing infestations. So, let’s uncover whether bleach is the answer to your phorid fly woes.

Why are phorid flies disliked by people?

Phorid flies are widely disliked by people for several reasons, primarily due to their nuisance nature and the potential health concerns they pose. Here are some key factors contributing to the general aversion towards phorid flies:

  1. Health concerns: Phorid flies can spread bacteria and pathogens as they move from decaying matter to human food and surfaces, posing health risks.
  2. Persistent infestations: Their rapid breeding cycle and ability to thrive in moist, organic environments lead to quick and persistent infestations, making them difficult to eradicate.
  3. Nuisance: Their presence in large numbers, especially around kitchens and bathrooms, creates an annoying and unhygienic environment.
  4. Difficult to control: Due to their small size and habit of breeding in hard-to-reach areas, phorid flies are challenging to control and eliminate.
  5. Damage to plants: In some cases, phorid flies can harm houseplants by laying eggs in the soil, affecting plant health.

Phorid flies are feared for their filth, quick reproduction, health concerns, nuisance, infestation control issues, and psychological anguish, which are frequently signs of inadequate cleanliness.

The role of bleach in your battle against phorid flies

Now, let’s delve into the heart of the matter: the effectiveness of bleach in dealing with phorid flies. Bleach, scientifically known as sodium hypochlorite, is a powerful disinfectant known for its ability to kill bacteria and viruses. It’s a common household item, often used for cleaning and disinfecting various surfaces.

When it comes to phorid flies, bleach can be a double-edged sword. Its effectiveness largely depends on how and where it’s used. Bleach is capable of killing phorid flies on contact. However, it’s not a straightforward solution for a phorid fly infestation.

Will bleach kill phorid flies

Yes, bleach can kill phorid flies on contact. However, using bleach alone is not a comprehensive solution for eliminating a phorid fly infestation. 

While bleach is effective in killing adult flies it directly comes into contact with, it does not address the underlying issue of breeding sites where phorid flies lay their eggs. 

For a more effective approach, it’s important to combine the use of bleach for cleaning and disinfection with other methods, such as removing breeding sites, maintaining cleanliness, and possibly using fly traps or seeking professional pest control assistance.

Why bleach is not a magic bullet

The primary challenge in using bleach to combat phorid flies lies in its nature and application. Bleach is highly effective in killing bacteria and germs on surfaces but has limitations when targeting insects like phorid flies. 

These flies are often found in hard-to-reach areas, such as drain pipes and garbage disposals, where applying bleach can be challenging.

Moreover, bleach can only kill the adult flies it comes into contact with. It does not effectively address the root of the infestation – the breeding sites. 

Phorid flies lay their eggs in damp, organic material. Unless the breeding sites are eliminated, new flies will continue to emerge, rendering your efforts with bleach somewhat futile.

5 Effective ways to deal with phorid flies

To effectively control a phorid fly infestation, a multi-pronged approach is necessary. Here are some steps you can take:

  1. Identify and eliminate breeding sites: The first and most crucial step is to locate and eradicate the breeding grounds of the phorid flies. These are typically moist areas with decaying organic matter. Common sites include drain pipes, garbage disposals, trash cans, and overwatered houseplants.
  2. Use bleach judiciously: While bleach isn’t a standalone solution, it can be a useful part of your strategy. Use it to clean and disinfect areas where phorid flies are seen. For drains, a mixture of baking soda and vinegar followed by hot water can be more effective than bleach.
  3. Employ fly traps: Fly traps can be used to capture adult phorid flies. These can be commercial sticky traps or homemade traps using a jar, vinegar, and a paper funnel.
  4. Maintain cleanliness: Regularly clean your home, especially the kitchen and bathroom areas. Keeping these areas dry and free of organic waste can prevent phorid flies from finding suitable breeding spots.
  5. Seek professional help: If the infestation is severe, it may be wise to consult a pest control professional. They can offer more targeted and potent solutions to eradicate phorid flies.


  1. What is the best drain cleaner for phorid flies?

Enzymatic drain cleaners are most effective against phorid flies. They naturally break down organic matter in drains, eliminating breeding sites and preventing future infestations.

  1. What is a home remedy to get rid of phorid flies?

A mixture of apple cider vinegar and dish soap makes an effective home remedy. The vinegar attracts the flies, and the soap traps them. Boiling water down the drains can also disrupt their breeding cycle.

  1. What spray kills phorid flies?

Insecticide sprays containing pyrethrin or pyrethroids effectively kill phorid flies. Target areas where flies are prevalent and follow safety instructions. Use in conjunction with other methods for comprehensive control.


In conclusion, while addressing the question Will bleach kill phorid flies? we find that bleach does have the capacity to kill these pests on contact. However, it’s important to remember that this is not a comprehensive solution. The key to effectively managing a phorid fly infestation lies in a holistic approach. This includes eliminating breeding sites, maintaining cleanliness, and possibly using additional methods like fly traps or professional pest control services. Bleach can be part of your arsenal in fighting phorid flies, but it should be used in conjunction with other strategies to achieve lasting results and a fly-free environment.
