The insect world is so vast that they outnumbered the human race by far, the human population is”7.9 billion” whereas there are estimated to be “10 quintillion insects” on planet earth. I know, the word quintillion can twist your tongue or cause you to get tongue-tied, That’s a lot of insects, many of these insects can be found in our homes and gardens.

Some of these insects are beneficial for our garden plants some of which include pollinators such as butterflies and bees while others police or protect our garden plants from (bad bugs) garden insect pests. Among beneficial insects are ladybugs, praying mantis, lacewings, dragonflies, solider beetles, ground beetles, syrphid fly, braconid-wasp, etc…

Then there are the bad bugs such as aphids, mealybugs, scales, spider mites, boxelder bugs, black vine weevil, cabbage lopper, blister beetle, etc.

What is so amazing is just as garden insect pests make a meal out of garden plants there are also plants that make a meal out of insects which we will be discussing. If your desire is to know more about these plant types then continue reading as we enter the amazing world of plant-eating insects.

Can Plants Eat Insects?

Below we will be discussing 5 plants that eat insects.

1. The Venus Flytrap

Venus Flytrap

The Venus flytrap is probably the most common carnivorous insect-eating plant, the Venus flytrap has a very interesting and unique appearance this insect-eating plant lures its prey by opening up its mouth like leaves remaining motionless. When the unexpected prey brushes past or decides to take a rest the tiny hair that is sensitive to this plant causes the leaves to shut close trapping insects inside. The victim then becomes the venus flytrap meal.

Care of Venus flytrap

Venus flytrap thrives in poor acidic soils that are well-drain but still have some dampness, the environment of the venus flytrap should be humid. Although this plant thrives best in damp soil don’t allow your venus flytrap to stand or grow in soils that are constantly wet. These plants require 4-6 hours of sunlight.

2. Purple Pitcher Plant

There are said to be a number of pitcher plants native to North America, however, most of them are native to the Southeast. The pitcher plant lures insects through its color, scent, and nectar. Once the insect is trapped inside the purple pitcher plant, the hairs and the digestive acids take care of the rest.

The pitcher plant slowly breaks down the insects and absorbs nutrients that are essential for this plant to survive. Use a good potting mixture and never allow the mixture to dry out. The use of distilled water or rainwater is a must because minerals and chemicals that are found in tap water will harm this plant.

The humidity level should be moderate to high, it’s best to set this plant on a humidity tray to raise the moisture around it. The purple pitcher plant thrives best in bright locations with some direct sunlight. Exposure to the sun will deepen the red/purple color of the leaves. Throughout the growing season, the soil should be evenly moist.

3. Sundew

Sundew species are native to every continent except Antarctica, sundews are extremely sensitive to touch. These garden plants have hair-like tentacles that reach out for insects once contact is made. With some species, the leaves of the sundew will curl up to trap or engulf the insects. depending on the species sundews sizes range from a penny to the size of small bushes.

Sundew Care

Sundew thrives as potted plants in a mixture of sphagnum moss and perlite or vermiculite, the soil must be constantly moist, this plant thrives best in full sun. Growing sundew indoors requires that you place them in a sunny location like a west or south-facing window, this plant can also survive in areas that have partial sun or indirect sunlight provided they get about 5 hours of sunlight each day.

4. Tropical Pitcher Plant

Tropical Pitcher Plant

Tropical pitcher plants are native to lands that border the Indian ocean, some tropical pitchers are woody plants and hung in a downward position.  These carnivorous plants trap insects by secreting sweet nectar, the insects are lured by this scent that is irresistible, but what the insect does not know is this sweet nectar is secreted in specific places on the trap.

Once the insect steps on the slippery peristome (upper rim) to consume the nectar they fall into the trap and drown at which time the insect is digested by the plant’s fluid.

Tropical Pitcher Plant Care

Tropical pitcher plants thrive best in a mixture of organic material, peat moss, and sand, this mixture should be kept moist not waterlogged or saturated which can lead to root rot. These plants need about 1o hours of sunlight each day when growing outdoors, if growing pitcher plants indoors placed them in a sunny location. Another method is to provide artificial lighting or a combination of both natural and artificial light is good also.

5. Yellow Pitcher Plant

The yellow Pitcher plant gets its name from its leaf structure that is shaped like a vessel to hold liquids, this plant thrives in Southeast Us in areas that are boggy and sandy. Insects are lured by the nectar scent that comes from the waxy potion pitcher tube that’s slippery, the insect once trapped slides down a coating of hairs that’s tiny. Once the insect reaches the zone where the digestive enzymes are located the insect’s nutrients are absorbed by digestive fluids.

Yellow Pitcher Plant Care

The yellow pitcher plant thrives best in the full sun, the soil should be well-drained acid soil. The soil should be consistently moist to wet but not waterlogged or water-saturated. Never allow the soil to dry out, during the winter months, mulch your yellow pitcher plant with pine needles to protect the plant from the cold temperature.

  2. Wow, this is my first time coming across this interesting topic. Who would have thought unpopular plants could be as powerful as setting a trap, and catching and eating insects. I remember some of these plants from childhood because I have also been their victim. I am glad they didn’t eat me then! lol

    I remember touching one that has the same description as a Venus flytrap and the thorns stuck into my fingers. It was a painful experience. These plants are well prepared by nature for self dense.

    Thanks for sharing this interesting and educative article.

  3. Wow, these are some fascinating plants! I really enjoy plants that actively move throughout the day, but the carnivorous nature of these plants really adds a sense of danger and excitement. Thanks for sharing tips on how to grow these both indoors and outdoors. I have pets that might find the plants inside – do you know if any of the pitcher plants are poisonous to pets?

    • These plants are amazing in what they can do, as far as I have read ” None of the commonly propagated carnivorous plants is considered seriously toxic to cats and dogs” although there have been some reports of “mild digestive upset when ingested by cats which is none life-threatening” Hope this help. It is still good to do further research and to get with your garden nurseryman to confirm if these plants are non-toxic to animals and humans (children) as well.

  4. Thank you for your post, Norman! I had no idea there were so many different species of plants that eat insects. I love to garden, but like most people, don’t care for bugs. Especially in my house! It’s good to know that several of the plants you mentioned in your post can survive as house plants!

    I have a beautiful perennial that blossoms every year that I refer to as my stinky fish flower. The first two days that it is in full bloom, it smells like rotting fish, no joke. You would think something like that would also devour bugs, possible something even bigger, but it doesn’t. It just looks pretty for a few days, then the flower shrivels away. It is arum drancunculus, I believe is the scientific name, in case you’re interested. The flower gets nice and big and is a deep purple color, but I wouldn’t suggest having near a window that you leave open!

    I just may try one or two varieties of the plants in your article to help control the bugs that show up in my house from time to time. I appreciate the information!
