Let’s be honest—when people think of Costa Rica, they think of beaches, volcanoes, sloths—and then someone says, “But don’t they have huge bugs?!” They do. You will see a few. But bugs in Costa Rica are part of the charm. Some are tiny, some glow, and some look like they came from outer space. No joke—if you’re on board with it, bugs in Costa Rica can be one of the best parts of your trip. And no—most of them don’t bite—unless you’re a mango.
So before you start fretting about bugs in the jungles of Costa Rica, read this guide to insects in Costa Rica, how to deal with them, and why taking a bug-themed night adventure may end up being the best thing you do on your trip.
Costa Rica Bugs: What to Expect (and What Not to Panic About)
Tropical country = tropical insects. That’s just part of the package. But unlike the horror stories you might have read online, most of the insects you’ll see in Costa Rica are harmless – or at least uninterested in humans. Yes, you may find a beetle on the bathroom wall or see a line of ants doing their thing. But remember, you are now in their world. Insects here are not a nuisance – they are part of the spectacle.
Meet the Locals: Common Costa Rica Insects You’ll See on Your Trip
Here’s a quick tour of the usual suspects you might bump into (sometimes literally):
- Mosquitoes – Yes, they’re here. Especially near water, especially at dusk. Bring repellent.
- Butterflies – Costa Rica is home to over 1,200 species, including the giant blue morpho.
- Fireflies – Magical flashes in the dark. Nothing like a real-life light show in the jungle.
- Leafcutter ants – You’ll spot these guys carrying leaves bigger than themselves in perfect little highways.
- Beetles – From shiny green scarabs to massive rhinoceros beetles, these guys are the tanks of the insect world.
- Dragonflies – Especially near rivers and waterfalls – fast, graceful, and totally harmless.
Beautiful or Bizarre? The Strangest Insects in Costa Rica
Costa Rica has insects that look like sticks, leaves, flowers – you name it. I once spotted a katydid that looked exactly like a green leaf with bite marks. No joke. You might also come across:
- Stick insects – Masters of camouflage.
- Orchid mantises – White and pink, they look like actual flowers.
- Lanternflies – With their wild patterns and weird heads, they’re like flying abstract art.
Nighttime Safari: Take a Bug-Focused Jungle Tour
Want to really get to know Costa Rica bugs? Go on a nighttime jungle tour. No, not the scary kind – I’m talking about guided night walks in the forest with an expert who can spot a frog on a leaf from 10 meters away and explain why that glowing spider isn’t actually radioactive.
These tours are safe, fun, and surprisingly chill. You’ll see insects, frogs, sleeping birds, and maybe a tarantula or two (don’t worry – they’re more afraid of you). Bring a headlamp, wear closed shoes, and get ready to hear the forest come alive. It’s one of those experiences you’ll talk about way more than any zipline ride.
Are Costa Rica Bugs Dangerous? (Spoiler: Not Really)
The short answer? Nah. The long answer: you might get a mosquito bite or two, and you should avoid putting your hand in dark crevices (because, well, spiders). But serious issues with Costa Rica insects are rare. There are a few venomous species out there, but they’re not aggressive and won’t bother you unless you go poking around where you shouldn’t.
Use common sense, wear repellent when needed, and you’ll be fine. I’ve spent countless nights in the jungle and still have all my limbs.
What to Pack: Bug Spray and Other Insect Survival Tips
Here’s my go-to bug strategy when traveling around Costa Rica:
- Bring a good DEET-based repellent – especially for the coast and rainforest.
- Wear long sleeves and light-colored clothing at dusk – mosquitoes love ankles.
- Pack a citronella candle if you’re staying somewhere remote – or just to feel fancy.
- Don’t freak out if something lands on you – it probably won’t bite, and screaming only helps the mosquitos find you faster.
- Keep your lights low at night – unless you like collecting flying friends.
Why Costa Rica Insects Are Actually Kind of Amazing
Okay, confession time: I used to hate bugs. But living in Costa Rica changed that. Now I look at a giant beetle or glowing caterpillar and think, How on earth is that real? Insects here are weird and wonderful, and if you slow down and pay attention, you start to appreciate just how alive the jungle really is.
So yeah, the bugs are here. But they’re not the villains – they’re part of the pura vida story. You just have to meet them on their level.
