Can Drain Flies Lay Eggs In Humans?

Drain flies cannot lay eggs in humans because humans are considered sterile environments, which the drain fly cannot survive in. The environment around you is more concerning than your body unless you are unhygienic. In that case, you should be extremely conscious, given drain flies can carry many pathogens that are dangerous for your health. 

Drain flies are more interested in uncleanly environments like standing water to lay their eggs than on human skin. That is why you will find them in your sink, where they can lay larvae and consume leftover food remnants. To prevent drain flies from laying eggs in your home, keep your house clean and stay hygienic by showering regularly.

Can Drain Flies Lay Eggs on Humans?

Drain flies cannot lay eggs on humans since the human body is an inhospitable environment to the drain fly. The drain fly requires somewhere dirty with plenty of nutrients, and the human body is considered too sterile for larvae. In contrast, drain flies can fester as larvae inside your home if there is a damp and dirty place to lay their larvae, like a dirty sink.

Where Do Drain Flies Lay Eggs?

Drain flies prefer to lay their eggs in moist environments like standing water because it gives them the chance to prosper. Standing water is perfect because it is warm, unclean, and has plenty of nearby food for the larvae to consume.

Are Drain Flies Dangerous To Humans?

While they cannot lay eggs on humans, that does not mean they are not dangerous to humans. Drain flies carry harmful diseases that can cause illness in humans. They can transmit their pathogens and bacteria by landing on household items, making them hazardous insects.

To protect yourself from the dangerous pathogens drain flies carry, eliminate all standing water and keep your home clean. Maintaining good personal hygiene also ensures drain flies are not attracted to your home. 

How To Protect Yourself From Drain Flies

Drain flies can be dangerous to your health, so it is essential to keep your home clean. Avoid letting standing water form on your property. Stagnant water can sustain drain fly larvae, especially in your sink, where the larvae can gather nutrients from leftover food scraps stuck inside your drain pipe.

Living in a place with excellent drainage would be best for avoiding drain flies, so rainwater does not form on your property after storms. While they mainly form indoors in drains, they can also develop because of the stagnant water in drain pipes. If you do not live somewhere with good drainage, consider trying to install a new drainage system.

Keep your home clean

The best way to protect yourself from drain flies is to keep a clean environment. A clean environment will not attract drain flies because they require nutrients from dirty water to thrive. If you regularly clean your home, it will keep drain flies from laying their larvae.

Regularly clean your drains

It will protect you best against drain flies if you regularly clean your drains at least twice per month with a mixture of salt, baking soda, and vinegar. Follow this mixture with a pot of boiling water, pouring it slowly to prevent splashing.

Eliminate standing water

Drain flies lay their larvae in standing water. So, you should remove all standing water from your home to prevent drain flies from laying their eggs in your home. Instead of standing water, use running water in your home to clean yourself.

Pour out standing water

If you find standing water in or around your house, dump the dirty water far away from your home in a place with excellent drainage. Pouring the water near your home can create outdoor puddles perfect for cultivating larvae. Be sure you are far enough away from your home if you consider pouring it outdoors, or you will create the same problem outside your home, allowing them to come back inside once you open your doors or windows. 


After removing stagnant water from your home, you should sanitize the area thoroughly. Sanitization will ward off drain flies and prevent them from relaying larvae in the infestation area. If there are many drain flies in your home, try to clean the area as thoroughly as possible. Hire an exterminator if you struggle to remove the drain flies from your home. They are professionals skilled in eliminating larvae and grown flies.

Maintain good personal hygiene

Maintaining good personal hygiene will protect you from drain flies. The worse your hygiene is, the more likely drain flies will infest your home. Drain flies do not typically form on humans. However, they can be attracted to your home if you do not shower regularly.

Keep windows closed

Drain flies can get into your home through open doors and windows, so you should keep them closed to avoid an infestation. If you have stagnant water on your property, you should find a way to empty the water in an area that drains.


Can Drain Fly Larvae Get In Your Skin?

Drain fly larvae cannot get in your skin because they do not seek human hosts. Human skin is too clean and dry for drain flies, with insufficient food nearby to sustain the drain fly larvae.


Drain flies lay eggs in dirty, moist environments. They do not lay eggs on human skin because the human body is an inhospitable environment for the drain fly. Human skin is too sterile for the drain fly, which typically requires dirty, standing water to raise its larvae.

To keep drain flies from forming in your home, keep your home clean, maintain good personal hygiene, and avoid letting standing water form near your home. Otherwise, you risk drain flies laying larvae in your home. If you find standing water in your home, remove it promptly and thoroughly clean the area where you found the stagnant water. Doing this will prevent the drain flies from relaying their larvae.
