What Is The Best Carnivorous Plant To Get Rid of Fruit Flies?

Carnivorous plants are fascinating and unique species that can play a beneficial role in controlling small insect pests, including fruit flies. When it comes to effectively dealing with fruit flies, several carnivorous plant species can be quite useful. Among them, the Venus flytrap (Dionaea muscipula) stands out as one of the most popular and effective choices.

Why Venus Flytraps are a Great Choice:

  1. Highly Effective Predators: Venus flytraps are well-known for their snap traps, which are specialized leaves that can quickly close and trap insects when triggered. These traps are specifically designed to capture small insects, including fruit flies.
  2. Attracted to Fruit Flies: Venus flytraps are naturally attracted to the scent of fruit flies, which makes them an ideal choice for fruit fly control. When fruit flies approach the plant, they trigger the sensitive trigger hairs on the trap’s surface, causing it to snap shut.
  3. Easy to Care For: Venus flytraps are relatively easy to care for, making them accessible to both experienced and novice gardeners. They require bright, indirect sunlight, distilled water, and well-draining soil, typically a mix of sphagnum moss and perlite.
  4. Non-Toxic: Unlike chemical pesticides, Venus flytraps are non-toxic and environmentally friendly. They are a natural and safe way to control fruit fly infestations, making them a popular choice for organic gardeners.
  5. Educational and Entertaining: Venus flytraps are not only effective in controlling fruit flies but also make captivating conversation pieces. They are ideal for educational purposes and can be a source of entertainment and fascination.

Caring for Venus Flytraps:

While Venus flytraps are excellent at capturing fruit flies, they do require specific care to thrive and be effective in pest control:

  1. Light: Place your Venus flytrap in a location with bright, indirect sunlight. It needs around 12 hours of light daily.
  2. Water: Use distilled water or rainwater to keep the soil consistently moist but not waterlogged. Avoid using tap water as it may contain minerals that can harm the plant.
  3. Soil: Plant your Venus flytrap in a mixture of sphagnum moss and perlite. This soil combination provides the necessary acidity and drainage.
  4. Feeding: While Venus flytraps can capture insects, they may require supplemental feeding, especially in areas with fewer natural insect visitors. You can occasionally feed them small insects, but avoid overfeeding.
  5. Dormancy: Venus flytraps undergo a winter dormancy period when they require less light and water. During this time, they may appear less active, but this is a natural phase in their life cycle.

Other Carnivorous Plant Options:

While Venus flytraps are popular, other carnivorous plants like sundews (Drosera spp.) and pitcher plants (Sarracenia spp.) are also effective at trapping and digesting small insects. However, they may not be as attractive to fruit flies as Venus flytraps.

In conclusion, Venus flytraps are one of the best carnivorous plants for getting rid of fruit flies. They are not only effective pest controllers but also fascinating plants that can add a unique and captivating element to your home or garden. With proper care, they can be a natural and environmentally friendly solution to fruit fly problems.

The size of the prey

The carnivorous plants, which are placed in the apartment are usually not very large. With fruit flies, they can still easily cope. However, when it comes to eating normal house flies, then this can already be a problem.

The capacity of the plants is very limited and they can not necessarily choose which insects fall into their trap. If a fly that is too large is held, then it cannot be eaten. This will cause the trap to die and the insect to be released.

So if you have the idea that you can control larger insects with these plants, then this is not so easily possible.

One plant that has no problem with such large insects is the pitcher plant. However, keeping these at home requires a lot of care and preparation.

Do plants always need insects?

When the threat of insects declines, so does the food for the carnivorous plants. But how can they live with this omission?

In winter, when insect densities thin, food for plants in most cases remains absent. However, this need not be a major concern, as plants can go a long time without food.

The winter you can get the nutrients from their substrate and in most cases the plants build up a sufficiently large store. So you don’t have to worry about providing the plants with live food.

How are the insects attracted?

If there are only a few fruit flies or other insects in your home, then this is a good condition for now. But how do carnivorous plants work now to attract the few insects to them exactly?

It is widely believed that the plants emit a scent and this attracts the insects. This assumption was confirmed in a study – with one caveat.

This is because not all insects are attracted to the scent of the Venus flytrap. Researchers have shown that only hungry insects can be lured into the trap by the scent.

So if the insects can find plenty of food with you, then the plants’ attractants may be ineffective.

The scent that the Venus fly trap emits imitates the smell of flowers and fruits. In this way, the fruit flies are fooled into thinking that there is a food source nearby.

Does the Venus flytrap need fertilizer?

The advantage of the Venus flytrap is that it draws its nutrients from live food. So a fertilizer is not necessary. Feeding is also not necessary. The plant can survive a long time without food.

However, if there is absolutely no food available and you are afraid that the Venus flytrap will die, then you can use live food.

Placing dead insects on the Venus flytrap will not work. The fine hairs can sense if it is a live animal that is still moving or if it is a dead subject.


Carnivorous plants are good for containing fruit flies. They can help prevent fruit flies from spreading in the first place and make them feel comfortable in your home.

Carnivorous plants are basically very low maintenance. Other than plenty of sun and water, they don’t need any special attention. There is no need to use a fertilizer, as the plants get their nutrients from the insects.

However, if you think you can contain an acute infestation of insects with these plants, you will probably be disappointed. This is because carnivorous plants are very limited in their capacity to kill insects.

However, if the insect infestation is to be contained just a little, then carnivorous plants are very suitable in the fight against fruit flies.
