The house fly is a common pest of the Muscidae family and is found in homes all around the world. House Fly Larvae are an important stage in the fly’s life cycle. House flies are attracted to food and often end up contaminating it.

In addition, they can spread diseases. The lifecycle of the house fly is interesting and complex, involving four different stages: egg, larva, pupa, and adult.

This article will look at the lifecycle of the house fly larvae and what you can do to get rid of them.

The house fly has a short lifespan, but it can reproduce quickly. A single female house fly can lay up to 500 eggs during her lifetime. The eggs are deposited on decaying organic matter, and the larvae will feed off the decomposing material.

The Life Cycle of House Flies

The life cycle of a housefly can be roughly broken down into four stages: the egg stage, the larval stage, the pupal stage, and the adult stage.

Each stage of the housefly lifecycle includes different categories and requirements. The egg stage lasts for around five days, during which time the eggs are laid and hatch.

The larval stage is the longest, lasting from two weeks to a month. In this stage, the larvae eat and grow until they reach their next developmental milestone, and then the larvae will feed on decaying matter until they pupate.

The pupal stage is very short- only about five days-and the larvae transform into adult flies. The adult stage is the shortest, lasting only about two weeks.

Interestingly, fly pupae are similar in function to butterfly cocoons. They protect the developing flies from environmental hazards and predators.

Within two to three days of emerging from their pupal stage, female houseflies are able to reproduce. They lay eggs in decomposing organic matter, and the larvae that hatch feed on the rotting matter. These larvae will undergo three molts before pupating and becoming adult houseflies.

House Fly Larvae

Housefly larvae are the immature form of house flies. They go through a four-stage lifecycle, during which they grow and develop into adult house flies. 

House fly larvae are a critical part of the lifecycle of the house fly. The head of the larvae contains one pair of dark hooks that help them grasp food and do not have large eyes.

The spiracles are slightly raised, and the spiracular openings are sinuous slits surrounded by an oval black border.

Larvae are usually 7 to 12 mm long and have a greasy, cream-colored appearance. They prefer high-moisture manure, which helps them survive.

The larvae develop best at a temperature of 35 to 38°C but can survive at temperatures as low as 17 to 32°C. They complete their development in four to 13 days at optimal temperatures but require 14 to 30 days at lower temperatures.

Housefly larvae develop in various substrates but are especially common in animal manure. This provides the larvae with a rich source of nutrients and allows them to grow quickly. Once the larvae are full-grown, they will crawl to a dry, cool place near breeding material and transform into pupae.

How to biologically control housefly larvae?

The house fly is a common pest found all over the world. While there are many ways to control these pesky organisms chemically, there is also a biological method that you can use.

Biological control, such as using nematodes or parasitic wasp, can effectively control housefly populations.

There are many different ways to suppress houseflies biologically. Some common methods include using parasitic wasps, nematodes, and Bacillus thuringiensis israelensis (Bti). 

How to control house fly larvae by using chemical methods?

The most common approach is to use adulticides or larvicides. Adulticides are chemicals that kill adult flies, while larvicides are chemicals that kill fly larvae. Adulticides and larvicides each have their strengths and weaknesses. 

Insecticide resistance has been a problem for many years in controlling house fly larvae conditions. Chemical methods, such as spraying insecticides, are often used to eliminate these pests. However, the flies have developed a resistance to the chemicals, and they are not as effective as they used to be.

Chemical methods are available to help control house fly larvae. However, using insecticides on manure is discouraged because it interferes with the biological control of flies.

It should be noted that you can use fly baits to poison adult flies, but exposing them to insecticides and pesticides has led to the development of insecticide resistance. You can also spray insecticides on breeding grounds, but this is not always effective because organic matter often protects larvae.

How Do House Flies Get into the House?

House flies get into the house area by two primary methods: air currents and odors. They are attracted to both movement and smells, so they often fly into the site of the house through an open door or window.

Additionally, if there is garbage or rotting food in the vicinity of the house, the smell will get through any opening they can find.

House flies can sense different types of heat from buildings. They will fly towards the warmth, and if there is an opening such as a door or window, they will enter the building.

Signs of a House Fly Infestation

Signs of the species infestation may include fly eggs or larvae, feces. In addition to seeing the house fly around the home, people may also hear them buzzing. This is a sign that there is an infestation, and you should take care of it as soon as possible.

How do you get rid of a sudden housefly infestation?

Houseflies can be a problem in any environment, but they are especially troublesome indoors. They contaminate the surfaces with their droppings. If you have a sudden house fly infestation, there are several things you can do to get rid of them.

To get rid of houseflies, you need to identify where they are coming from. Once the source is identified, it needs to be eliminated for the flies to go away. Indoor fly traps and sprays are two effective methods for getting rid of a sudden house fly infestation.

Threats Posed By House Flies

House flies can pose a number of threats to humans. Not only are they unsightly, but they also spread a number of diseases, including salmonellosis, typhoid, and tuberculosis. They can also contaminate food and cause other health problems.

Houseflies are a common nuisance in the summertime and can be a health hazard in this case. 

Housefly larvae pose a threat to humans because they defecate constantly. This creates a breeding ground for bacteria, and the flies can spread disease as they move from place to place.

What is the life span of a Housefly?

Housefly larvae live for around 14 days. During this time, they will go through a number of changes as they grow and develop into adult houseflies.

In addition, flies have an incredibly fast life cycle. Housefly larvae can go from egg to adult in as little as two weeks. This is due to the fact that flies have the ability to perceive time differently than humans.

Final Thoughts

Housefly larvae are the immature form of house flies. They are attracted to pet waste because of its strong odor. The larvae feed on the waste, which helps to break down the material.

In conclusion, house flies are very resourceful and can travel long distances in order to find food. They often migrate up to 20 miles, so it is important to take steps to prevent them from breeding near your home.

In conclusion, house fly larvae are a target part of the natural ecosystem. While they may sometimes be seen as pests, they play an important role in the environment.
