Do Venus Fly Traps Eat Gnats [Insects Control Hacks in 2024]
Do you have a Venus fly trap? Chances are, you do – they’re one of the most popular home garden plants around. But did you know that your Venus fly trap might also enjoy eating gnats?
Yes, it’s true! Gnats make up a large part of the Venus fly trap’s diet, and if you’re looking to keep your plant happy and healthy, you’ll want to make sure you’re providing plenty of them.
Here we’ll take a closer look at the relationship between Venus fly traps and gnats, and give you some tips on how to best feed your plant. So read on to learn more!
Do Venus Fly Traps Eat Gnats?
Carnivorous Venus fly traps are found in the United States temperate zones and feature a remarkable feeding strategy.
With the help of their leaves, they catch insects, which are then broken down by digestive secretions. While gnats do make up a portion of a Venus fly trap’s diet, it is not the primary source of nutrition.
As a rule, these plants will consume bugs like ants and beetles. But if you want to, you can feed your plant gnats once or twice weekly.
Venus flies trap prey mostly on gnats, although they will also devour flies and other insects of a similar size. A majority of owners report using their Venus fly traps for general insect control.
There are many species of venus fly traps, but they all have leaves that look like they’re covered in teeth and are used to catch insects.
Thousands of tiny hair-like trigger hairs, each one sensitive to motion, cover the outer leaf surface.
These trigger hairs, when brushed, curve inward toward the leaf’s center, where a small pool of digestive juice called mucilage is stored.
Rhizoid-like structures, which resemble miniature roots, absorb nutrients from the mucilage because it contains enzymes that break down proteins into simple sugars and amino acids.
To kill its prey, the leaf can either suffocate it or dissolve it with digestive juices.
Do Venus Fly Traps Eat Fungus Gnats?
Yes, Venus flytraps (Dionaea muscipula) are known to eat fungus gnats (Bradysia spp.).
Fungus gnats are small insects that often inhabit the moist soil around the roots of plants, which is also where Venus flytraps grow naturally.
When a Venus flytrap detects the movement of a potential prey item, such as a fungus gnat, it triggers the trap to close shut.
The trap then begins to digest the prey using enzymes secreted by the plant, which break down the insect’s tissues into nutrients that the Venus flytrap can absorb and use for its own growth and survival.
While Venus flytraps are often associated with capturing and eating flies, they are capable of catching a variety of small insects, including ants, spiders, and beetles, as well as fungus gnats.
Why does Venus Fly Trap Eat Gnats?
First of all, why exactly do Venus fly traps eat gnats? The answer is quite simple – they need protein.
Venus fly traps obtain the majority of their nutrients from sunlight and water, just like any other plant. However, they also rely on catching and digesting insects to get the protein their bodies need for growth and survival.
Gnats make up a large part of this insect’s prey, especially in their natural habitat of wetland areas in North and South Carolina.
Studies have shown that about 60% of a Venus fly trap’s diet consists of small insects such as gnats or fruit flies. The rest is made up of larger insects such as beetles or spiders.
So if you want to keep your Venus fly trap happy and healthy, providing them with a steady supply of gnats is essential. Some other factors are beneficial in the case of gnats eating.
Size of a Gnat:
Gnats are tiny insects. They can grow to be anywhere from 1/8 and 1/4 of an inch in diameter.
They can get out of Venus flytrap leaves because of their small size. However, ants, which are smaller than most species of gnats, are common prey for Venus flytraps.
Limited trapping number:
Venus flytraps have a limited capacity for trapping insects, therefore they can only eat so many insects at once.
Since Venus flytraps typically have between three and ten traps, this is also the maximum number of insects that can be captured by one at once. It is extremely rare for all traps to be filled.
Slow digestion:
Venus flytraps have very long digestive processes, taking several days to weeks to completely digest their prey. In other words, a Venus flytrap probably won’t be catching anything every day.
Prey selection:
Venus flytraps use a strategy called prey selection to find the most suitable diet. When deciding whether or not to capture and digest a small prey item, they may decide to let it go free.
How to Feed Your Venus Fly Trap Gnats?
So how exactly do you go about feeding your Venus fly trap gnats?
First of all, it’s important to note that you don’t need to actively capture or hunt down gnats for your plant – they will attract them on their own with their sweet-smelling nectar.
However, if you want to give your plant an extra boost, there are a few things you can do.
One option is to place a small container filled with ripe fruit near the plant. The fruit will attract gnats, and as they come in for a snack they may just become one themselves.
Another option is to use a small paintbrush or Q-tip to transfer gnats from another area of your home (such as near a window) to the Venus fly trap’s waiting jaws.
Just be sure not to damage the plant’s delicate traps in the process.
It’s also important to remember that feeding your Venus fly trap too much can actually be harmful, so don’t go overboard by offering them insect prey.
Once or twice a week should be enough, and always make sure they have ample sunlight and water before introducing any extra food sources.

Are Venus Flytraps Effective Gnat Controllers?
In addition to providing them with protein, feeding your Venus fly trap gnats can also serve a practical purpose – reducing the overall gnat population in your home.
Since these plants actively attract and consume insects, they can make for effective natural pest control in your house or garden.
However, it’s important to note that one plant alone will not make a significant dent in a major infestation.
For best results, consider placing multiple Venus fly traps throughout your home and garden to create a more comprehensive insect control system.
Are Fungus Gnats Harmful to Venus Flytraps?
While Venus fly traps can and do consume fungus gnats, it’s important to note that these insects can also pose a threat to the health of your plant.
Fungus gnats lay their eggs in damp soil, where their larvae then feed on organic matter and root secretions. If left unchecked, they can cause damage to a Venus fly trap’s roots and potentially even kill the plant.
To prevent this, make sure to keep your Venus fly trap’s soil consistently moist but not overly wet. And if you notice a fungus gnat infestation, take steps to eliminate them before they harm your plant.
Fungus gnat larvae can destroy a juvenile Venus flytrap by munching on its leaves and roots. A fungal infection is possible after the plant’s susceptibility increases.
Conclusion
Venus fly traps can and do consume gnats as part of their diet. However, it’s important to remember that these plants have a limited capacity for trapping and digesting insects, and shouldn’t be overfed.
Additionally, while they can serve as natural pest control in your home or garden, one plant alone will not make a significant impact on a gnat infestation.
That being said, they can still help reduce the population and should be monitored for potential harm from fungus gnats.
FAQs
