Flies are a relentless nuisance in homes and gardens, but carnivorous plants can be a surprisingly effective (and stylish) solution. These plants have evolved wild ways to lure, catch, and digest bugs, giving you a bit of natural pest control while also looking pretty cool on your windowsill or in the yard.
Carnivorous plants actively capture and consume flies using all sorts of weird and wonderful structures – think snap traps, sticky leaves, and pitcher-shaped cups. This list rounds up 20 different fly-eating plants, some famous, others you might never have heard of. There are sticky-leaved sundews, snap-traps, and even those odd pitcher types that look like something out of a sci-fi movie!
1) Venus Flytrap (Dionaea muscipula)
The Venus flytrap is probably the most iconic carnivorous plant out there. It’s native to the soggy wetlands of North and South Carolina and has those classic jaw-like leaves that snap shut when something tasty wanders in.
If a bug touches those trigger hairs inside the trap twice in quick succession, the whole thing clamps shut – pretty dramatic! After that, the plant digests flies, mosquitoes, ants, and even the odd spider, making up for the nutrients it can’t get from its soil.
You can grow Venus flytraps indoors with enough light and by sticking to distilled water. Just don’t give them tap water; they’re picky that way.
2) Pitcher Plant (Sarracenia species)
Sarracenia species are North American natives and absolute pros at catching flies. Their trumpet-shaped leaves work like passive traps, luring insects in with flashy colors and sweet smells.
Once a fly slips inside, there’s no getting out, as downward-pointing hairs keep them from climbing back up, and eventually the plant digests them with enzymes. Stick one of these in your bog garden and you’ll get fly control with a side of botanical drama.
3) Cobra Lily (Darlingtonia californica)
The Cobra Lily is a strange and striking carnivorous plant from Northern California and Oregon. It’s actually the only species in its genus, which is kind of neat.
It sports these curving, lime green pitchers that look uncannily like a cobra about to strike. The hood even has forked, fang-like appendages for extra effect.
Flies are drawn in by nectar near the opening, but once inside, they get confused by the translucent patches and wind up falling into digestive liquid at the bottom. Nature’s got a sense of humor, apparently.
4) Sundew (Drosera species)
Sundews, with over 200 species, catch flies using glistening, sticky droplets on their leaves. When a fly lands, it gets stuck in the gooey secretions coating the plant’s fine stalks.
The sundew then slowly digests its prize over several weeks. These guys love boggy spots, so if you’ve got a damp area, they’re great for fly control and look pretty magical up close.
5) Butterwort (Pinguicula species)
Butterworts are fly-trapping plants with sticky leaves covered in tiny hairs. Their mucilage acts like natural flypaper, catching gnats, fruit flies, and springtails that wander onto the leaves.
After trapping something, the plant releases digestive enzymes to break it down. With over 120 species, butterworts are easy to grow and work well as natural pest controllers indoors.
6) Bladderwort (Utricularia species)
Bladderworts are a wild bunch, with about 233 species found pretty much everywhere except Antarctica. They thrive in freshwater habitats and soggy soils, sometimes floating, sometimes rooted.
They use tiny hollow bladders on their leaves to suck in prey. When a small animal triggers the trap, it’s pulled in by a vacuum and digested. It’s a blink-and-you-miss-it kind of action.
7) California Pitcher Plant (Darlingtonia californica)
The California pitcher plant, or cobra lily, pops up in Northern California and Oregon, hanging out in chilly, nutrient-poor bogs. Its hooded, fang-tipped structure really does look like a cobra on the prowl.
This carnivorous plant uses a pitfall trap, luring flies into its tubular leaves where they become hopelessly stuck and eventually digested.
The yellow-green pitchers can get impressively big in their marshy homes.
8) Monkey Cup (Nepenthes species)
Monkey Cups are tropical pitcher plants from Southeast Asia and Australia, with about 170 species in the genus. Their cup-shaped traps hang from vines or pop up at ground level, making them very much the show-offs of the carnivorous plant world.
They lure flies and other bugs into their pitchers, where the prey drowns in digestive fluid. If you want something different for your houseplant collection, Nepenthes in a hanging pot is both functional and a conversation starter.
9) Corkscrew Plant (Genlisea species)
Corkscrew plants grow in soggy spots across Africa, Central, and South America, with about 30 species to choose from.
These plants trap prey using weird underground leaves that spiral like corkscrews. Downward-pointing hairs force microscopic critters deeper in, and there’s no escape.
Genlisea are less about flies and more about catching protozoans and tiny microfauna underground, but their trapping mechanism is fascinating all the same.
10) Tropical Pitcher Plant (Nepenthes truncata)
Nepenthes truncata is famous for its massive pitchers – big enough to trap not just flies but larger insects, too! Hailing from the Philippines, it grows on Dinagat, Leyte, and Mindanao islands, sometimes at pretty high elevations.
Its heart-shaped leaves and dangling pitchers filled with digestive fluid make it stand out. Bugs wander in, get stuck, and that’s dinner sorted for the plant.
11) Japanese Pitcher Plant (Sarracenia purpurea)
Sarracenia purpurea, or the purple pitcher plant, is a North American native with squat, semi-upright pitchers and striking burgundy-red veins.
It catches flies, beetles, ants, and other insects in its modified leaves. Unlike some pitcher plants, its lid stays open, so prey just falls right in. It’s tough enough to handle cold climates, making it a solid choice for natural fly control outdoors.
12) Albany Pitcher Plant (Cephalotus follicularis)
The Albany pitcher plant is a compact species from southwestern Australia. It grows small, moccasin-shaped pitchers, usually just a couple inches long at most.
Attracted by the scent, insects tumble into the digestive fluid at the bottom. The gravity-powered trap is simple but effective, making it a must for any carnivorous plant fan.
13) Trumpet Pitcher (Sarracenia leucophylla)
The Trumpet Pitcher, native to North America, traps flies and other insects in its tall, slender pitchers. The tops are white with red or green veins, drawing in wasps and flies alike.
Nectar and colorful patterns lure the prey into the narrow cone, where the slick interior makes escape impossible. The plant then digests whatever it catches.
14) Dewy Pine (Drosera filiformis)
The thread-leaved sundew has upright, thread-like leaves that attract low-flying insects. Spiraling sticky leaves are covered with gluey hairs that trap bugs with ease.
This plant can reach up to 10 inches and blooms with lavender-rose flowers on bare stalks. While it photosynthesizes, it relies heavily on digesting stuck insects for nutrients.
15) Lance-leaved Sundew (Drosera intermedia)
The lance-leaved sundew, or spoonleaf sundew, is found in wetlands all over North America, Europe, and parts of South America. Its long, narrow leaves form a ground-hugging rosette.
Sticky tentacles on the leaves secrete mucilage, trapping flies and other small bugs. The plant then digests its catch using enzymes, perfect for surviving in nutrient-poor soil.
16) Cape Sundew (Drosera capensis)
The Cape Sundew grows wild in South Africa’s Cape region. Its rosette leaves are lined with sticky, glandular tentacles that snag insects on contact.
When a fly lands, it’s caught in the goo and slowly digested over weeks. You can grow Cape Sundews indoors for natural pest control; they love wet, low-nutrient conditions and don’t need much fussing over.
17) Round-leaved Sundew (Drosera rotundifolia)
The round-leaved sundew pops up in bogs and marshes across North America, Europe, and Asia. Its circular leaves, arranged in a rosette, are dotted with red, sticky hairs.
Glistening droplets lure in flies and other insects, which get stuck and digested for nutrients. This plant does especially well in nutrient-poor wetland environments, making bugs its main mineral source.
18) Large-flowered Butterwort (Pinguicula grandiflora)
Large-flowered butterwort is a European carnivorous plant, especially common in the Pyrenees and Alps. Its sticky leaves trap flies and other small insects on contact.
When a fly lands, it gets glued down by mucilage, and the plant digests it with enzymes. This butterwort can handle cold winters and goes dormant in winter. Its big violet flowers are hard to miss; much larger than most other butterworts.
19) Hawaiian Bladderwort (Utricularia sandersonii)
Funny enough, despite the name, Utricularia sandersonii isn’t from Hawaii at all, it actually hails from South Africa. This quirky little terrestrial carnivorous plant hides its tiny bladder traps underground, waiting for unsuspecting prey to stumble by.
Its flowers are something else: delicate lavender and white, and if you squint, they really do look like little bunnies – hence the nickname “bunny bladderwort.” These blooms pop up a lot of the year, sometimes when you least expect it. The plant’s bladders use a sort of rapid-fire suction to snag tiny flies and microorganisms that get too close, which is honestly kind of wild when you think about it.
20) Small Bladderwort (Utricularia minor)
Small bladderwort is a curious little carnivorous plant, living mostly in shallow waters, marshes, and wetlands throughout North America, Europe, and parts of Asia. It doesn’t bother with roots, just floats or anchors itself wherever it likes.
The real magic is in its bladders, which work as tiny suction traps. When some unsuspecting aquatic insect or water flea brushes up against the trigger hairs, the bladder snaps open and pulls them in, almost like a vacuum, and then digests them. It’s pretty wild to watch if you ever get the chance.
You’ll spot this plant either clinging to something down below or just floating freely in the water, minding its own business until dinner comes along.
