Flies are one of the most common pests that we encounter in our daily lives. They can be found both indoors and outdoors, and can be a nuisance to deal with. A fly infestation can be a serious problem that needs to be addressed immediately. In this article, we will discuss the common signs of a fly infestation and how to deal with it.

Common Signs of a Fly Infestation

  1. Presence of flies: One of the most obvious signs of a fly infestation is the presence of flies in your home or workplace. Flies are attracted to food sources and can be found in areas such as kitchens, garbage areas, and pet waste areas.

  2. Eggs or larvae: Another sign of a fly infestation is the presence of eggs or larvae. These can be found in areas where flies lay their eggs, such as garbage cans or pet waste areas.

  3. Foul odor: A foul odor is another indication of a fly infestation. This odor is caused by the decomposition of organic matter which attracts flies.

  4. Unusual behavior of pets: Pets can sense the presence of flies and may become agitated or display unusual behavior when there is an infestation.

  5. Sticky or dark spots on walls or ceilings: These spots are caused by fly droppings and are a sign that there is a fly infestation in the area.

  6. Presence of maggots: Maggots are the larvae of flies and are often found in areas where there is decomposing organic matter.

  7. Increased activity at night: Flies are more active at night, so an increase in activity during this time can indicate an infestation.

How to Deal with a Fly Infestation

Dealing with a fly infestation requires a multi-pronged approach that addresses both the source and symptoms of the infestation. Here are some ways to deal with a fly infestation:

  1. Clean up: Cleaning up any potential food sources or areas where flies lay their eggs is essential in preventing a fly infestation. This includes cleaning up pet waste areas, garbage cans, and kitchen areas.

  2. Use fly traps: Fly traps can be used to catch and kill flies. There are many different types of fly traps available, including sticky traps, electric traps, and baited traps.

  3. Use insecticides: Insecticides can be used to kill adult flies and their larvae. These should be used with caution and according to the manufacturer’s instructions.

  4. Seal entry points: Sealing entry points such as windows and doors can prevent flies from entering your home or workplace.

  5. Get professional help: If you are unable to deal with the infestation on your own, it may be necessary to seek professional help. A pest control company can identify the source of the infestation and provide effective treatment options.


A fly infestation can be a serious problem that requires immediate attention. By recognizing the common signs of a fly infestation and taking steps to address it, you can prevent the infestation from becoming worse and protect yourself from the health risks associated with flies. Remember to clean up any potential food sources, use fly traps and insecticides, seal entry points, and seek professional help if necessary. With these steps, you can effectively deal with a fly infestation and prevent it from happening again in the future.
