Do Venus Flytraps Eat Gnats & Fruit Flies?

Full sized venus flytraps do not typically eat gnats or fruit flies. Gnats & fruit flies are too small to trigger the hairs to make the trap close on a venus flytrap. A smaller venus flytrap from 1-2 years old may be small enough to eat gnats and fruit flies. Even though venus flytraps eat gnats and fruit flies at a young age they are not the best carnivorous plant for gnat or fruit fly control. 

Lets talk more about what carnivorous plant you can get to control those pesky gnats and fruit flies!

Do Venus Flytraps Eat Gnats & Fruit Flies?

If you grow venus flytraps from either seed or propagation, you may have some around that are small enough to eat fruit flies and gnats. Typically, you are not getting venus flytraps for gnat or fruit fly control. Even the young venus flytraps that are capable of eating the gnats or fruit flies don’t have enough traps on them to actually make a difference. 

You could even debate that if a gnat were to trigger a full sized venus flytrap to close its trap it probably expends more energy trying to digest the gnat or fruit fly than it will get from the insect due it it’s small size. The venus flytrap has evolved to know it needs a larger insect to trigger the trap for it to be worth expending the energy to close. 

The other issue is that venus flytraps actually need to be triggered twice. They have evolved to know that it’s possible for a leaf or rain drop to trigger the trap to close. The venus flytrap actually waits for a secondary trigger once the trap closes. If the thing inside is not moving, the flytrap will likely not go thorough with full digestion to save energy. Digestion will only trigger if the thing its trapped is moving around on the inside and triggers the hair a second time. The flytrap then releases it’s digestive enzyme to eat it’s prey. A gnat would not be big enough to trigger the secondary response. 

Carnivorous Plants That Eats Gnats & Fruit Flies

Venus flytraps are amazing and one of the coolest carnivorous plants.They are small enough to eat gnats and fruit flies but will not make much of a dent with an outbreak. However, there are some amazing carnivorous plants that you can get pretty easily that will help you control your gnat and fruit fly problem. 

Were going to talk about some amazing carnivorous plants that will definitely eat some fruit flies and gnats in enough of a quantity that can actually help you out! 

Mexican Butterworts or Pinguicula

A ping is a much better option than a venus flytrap for eating gnats and fruit flies.

PINGS! One of my favorite carnivorous plants! These amazing carnivorous plants are not only better for eating gnats and fruit flies but they are even easier to care for! Venus flytraps can be really tricky to care for. They need full sun or at the very least a very strong grow light for 12-15 hours a day. Venus flytraps will not typically grow well on a window sill either, making them tricky to really care for. Venus flytraps also need a winter dormancy period. All of these factors make venus flytraps tricky to grow. 

Pings (short for pinguicula) are much easier to care for.

Each leaf on a ping can capture and eat many gnats or fruit flies.

They do still need light, but not nearly as much as a venus flytrap. They actually do really well on window sills and don’t typically need any kind of winter dormancy. But, most importantly, they can consume massive quantities of gnats and fruit flies. I had a breakout last year and my ping CLEANED up the gnats and fruit flies. Check out the video below so you can see just how many gnats and fruit flies my ping took care of. 

If you are interested in purchasing a ping, California Carnivores has a huge selection. I recommend a “Sethos” or “Weser” as they are pretty easy to care for but there are so many other great pinguicula out there you can get eat gnats and fruit flies.

Another thing I really love about pings is they produce beautiful little flowers. These flowers are often pinkish or purple that are always a great contrast to the green ping. You can get all different colors of pings that produce all different colors of flowers. If a ping is healthy, it can produce several flowers are a time. When the flowers are blooming, these little carnivorous plants are beautiful but also lethal!

Cape Sundew Or Drosera Capensis

Another great carnivorous plant that likes to eat gnats and fruit flies is the Cape Sundew. These are quite a bit different than pings but just as impressive. They grow long tentacle type leaves that develop little drops of dew. This dew is very stick and traps insects. The plant then releases an enzyme that breaks the insect down and uses it for food. 

These are just a bit more high maintenance than pinguicula. They need a little more light and just an uptick in humidity to continue to produce the dewy substance that traps the insects. They can do well in window sills if the window gets a lot of sun. They really like hanging out in a bathroom or kitchen sink. Being above a sink helps them get a little boost in humidity. 

Like pinguicula, they are much easier to take care of than venus flytraps. They also do not need any type of dormancy period. This helps them be useful for gnats or fruit flies year round! 

If you are interested it getting yourself a Cape Sundew California Carnivores is a great option! They are one of the most trusted and knowledgeable carnivorous plant nurseries around. Plus, you can get a 10% discount using the code CPHUB at checkout!

Do Venus Flytraps Eat Gnats: Conclusion

I often get the question on my YouTube channel, do venus flytraps eat gnats and fruit flies? It really comes down to the size of the venus flytrap. If it’s smaller it will eat gnats and fruit flies.

When it really comes down to it though, it doesn’t matter if a venus flytrap eats gnats or fruit flies because they can’t eat enough to help control the number of gnats or fruit flies you likely have. This question is asked because people want a natural way to help control these tiny insects. Venus flytraps are not the answer for that. 

The good news is that there are some other truly amazing carnivorous plants that are easier to care for and do a MUCH better job of eating gnats and fruit flies in large quantities. Most people have no idea that there is a wide world of incredible carnivorous plants out there!

Will Tap Water Kill A Venus Flytrap?

One of the most common mistakes people make is giving their venus flytrap tap water as soon as they get it home. In some rare instances, tap water might be okay but more often than not, tap water contains too many dissolved solids. These dissolved solids will burn the venus flytraps roots and slowly kill it. Tap water in most cases is toxic to a venus flytrap.

Know If Tap Water Is Safe With This Tool

It’s really important not to guess with your tap water. If you really want to know if you can give your venus flytrap tap water this tool will be necessary. Most tap water contains dissolved solids. These dissolved solids are potentially toxic to your venus flytrap. A TDS meter is a tool that allows you to measure those dissolved solids in your tap water. 

Not only will you be able to measure the “TDS” or total dissolved solids to see if it’s okay to give your venus flytrap, this will also allow you to see if your water is safe for drinking out of the tap. TDS meters are extremely affordable, you can grab one off Amazon for around 10-15 dollars. The one I’ve linked below is the one I use personally and it has never steered me wrong. 

They are extremely easy to use. You just stick the meter end into your water and it will display a reading. Make sure you only use the TDS meter when the water is room temperature. If the water is too hot or too cold it can skew the measurement. 

You want water that is below 50 PPM to safely use for venus flytraps. If you use water that contains around 50 PPM you will want to repot your flytrap once a year. Even at that low, the dissolved solids will build up in the soil over time. You can flush the plant with distilled water to help flush the dissolved solids out. You can measure the water coming through the plant to see if there is a build up. I personally prefer not to use anything over 10 PPM, this extends the substrate and I have less build up .

Superior Options To Tap Water

You may want to consider some different options to tap water for watering a venus flytrap.  You need water that has very little to no dissolved solids. Keep in mind that boiling water does not eliminate dissolved solids, only bacteria. It’s also important to note that most bottled waters do not eliminate dissolved solids. Some of them even add minerals for taste, which harm venus flytraps. I wanted to list some options below so you can find good water for your venus flytrap. 

Distilled Water From Store

If you want to avoid giving your venus flytrap tap water this is one of the easiest options. The only problem is it’s availability. In the section of your grocery or big box store that sells water there is usually a section that sells distilled water by the gallon. It usually ranges from 70 cents to 2 dollars a gallon. The bigger issue than price is that stores are OFTEN out of distilled water. There is nothing more frustrating than going to the store to get water for your plants and its all sold out. You can buy 5 gallons at a time when it’s in stock, but it can be quite the hassle. 

Zero Water Pitcher (My Favorite Option)

zero water pitcher not tap water

Since you should not be giving your venus flytrap tap water, one of the best options out there is a Zero Water Pitcher. This is a special water pitcher that eliminates all dissolved solids out of tap water so it’s safe for your venus flytrap. Keep in mind that not all water pitchers do this. Brita for example, will not get rid of dissolved solids. It takes a special filtration process to eliminate the dissolved solids. 

If you want to learn more about how much water each filter produces and how the Zero Water pitcher works, check out my full video review below. I go in depth with the Zero Water Pitcher so you can see if it’s right for you. If you don’t want to watch the video you can also click the link below to check it out along with the reviews on Amazon! 

One of the best benefits to getting a ZeroWater pitcher is that it comes with a free TDS meter for measuring water. Once you get your pitcher you can then also measure your tap water to see what the TDS levels are.

Collect Rain Water For Venus Flytrap Instead Of Tap Water

In most cases, rainwater is a better option than tap water for your venus fltyraps. It should be noted however that even rain water can be contaminated in more polluted areas. It still might be a good idea to grab a TDS meter to measure your rain water before committing to using it. I’t’s also good to point out that most people collect rainwater off of a roof of some sort. Sometimes gutters and roofs can collect chemicals that could be harmful to a venus flytrap. 

Rainwater is probably a good option but I’d recommend going with distilled water or the Zero Water pitcher above, just to be more safe. You’re venus flytrap is too precious to risk giving chemicals from roof collected rain water. 

Reverse Osmosis System

The absolute best option but least cost effective option is installing a reverse osmosis system. This is the option you would want if you have 50 or more carnivorous plants in your collection. This is not necessary for most people but is definitely an option. The nice thing about having the reverse osmosis system installed on your tap water is the benefits of both it being clean drinking water and good for your venus flytrap. 

They can be a little more expensive and still require filter replacements after so much use. You could reserve whichever sink you install if under to be just for carnivorous plants. This will ensure that you are never wasting the RO clean water. The Zero Water Pitcher is a much more affordable option. But if you want to really improve your drinking water and have a large source of zero PPM water, a reverse osmosis system might before you. 

Check out the system I recommend below! 

Conclusion

Can a venus flytrap have tap water? In most cases no… Unfortunately venus flytraps are a little too sensitive to dissolved solids to use tap water. Watering is one of the trickiest parts of growing healthy venus flytraps. I go in depth on everything water in my ultimate venus flytrap watering guide. It’s really in depth and gives you all the ins and outs of watering. I strongly recommend checking it out so you can learn how and when to water a venus fltyrap.

There are other things you need to know about growing healthy venus flytraps but learning the ins and outs of watering is really important. Understanding how tap water impacts your venus flytrap is really important. Knowing the dissolved solids in your tap water is necessary when deciding if you are going to use it. Getting a TDS meter will be necessary if you plan on using tap water. 

You can technically give venus flytraps tap water but you are taking a huge risk and gamble if you do it without a TDS meter.
