What Do Ladybugs Eat and Drink? Surprising Facts You Should Know

Introduction:

Ever watched a tiny ladybug crawl across your windowsill and wondered—what’s on its dinner plate? Turns out, these cute beetles are ruthless pest hunters and surprisingly picky eaters! According to entomologists, a single ladybug can eat over 5,000 aphids in its lifetime. That’s some serious garden pest control.

In this guide, we’ll explore everything you’ve never thought to ask about ladybug diets—what they eat, drink, and how their larvae survive. Whether you’re a gardener, a bug lover, or just plain curious, these little facts will surprise you. Let’s dive in!

What Do Ladybugs Eat?

Let me tell you—when I first started gardening, I used to think ladybugs were just cute lil’ red dots crawling around for fun. I had no clue they were practically garden warriors. I remember one spring when aphids had completely invaded my roses. I was panicking, Googling every chemical solution under the sun. And then… a swarm of ladybugs showed up out of nowhere. Within days? Boom—aphids gone. It felt like a miracle. But nah, it was just nature doing her thing.

So, what do ladybugs eat? The short answer: they love bugs. Not just any bugs, though—specifically soft-bodied pests like aphids, which are like filet mignon to a ladybug.

Primary Food Sources in Nature

Ladybugs are actually carnivorous, especially during their younger, hungrier stages. Here’s a breakdown of their top menu items:

• Aphids – easily their favorite snack. I’ve seen a single ladybug take out 40 in one sitting. Absolute machines.
• Whiteflies – they’ll munch these up when aphids are in short supply.
• Mealybugs – those cottony little pests hiding on plant stems? Ladybugs adore them.
• Scale insects – tiny armored suckers on leaves. Ladybugs are like little pest assassins when they find a cluster of these.
• Spider mites & thrips – small but mighty enemies of your garden, and thankfully also on the ladybug menu.

What blew my mind was just how voracious they are. I once read that a single ladybug can eat over 5,000 aphids in its lifetime. That’s more than I’ve probably eaten potato chips, no joke.

Seasonal Dietary Shifts

Now here’s something I didn’t know until a few years in—ladybug diets change depending on the season.

In spring and summer, when bugs are everywhere, ladybugs are in full predator mode. But come fall and winter, food becomes scarce. That’s when they switch to supplemental sources like:

• Pollen
• Nectar
• Honeydew (a sugary liquid secreted by—you guessed it—aphids!)

In fact, I’ve seen ladybugs cluster around overripe fruit like peaches and pears when bugs were hard to find. They’re kind of opportunistic that way. One winter, I left an old banana out in the shed by accident, and sure enough, I caught a few ladybugs having a fruity feast.

Pro Tip:

If you’re trying to keep ladybugs around your garden, make sure there’s a mix of pest bugs and flowering plants. I plant fennel and dill every season just to keep a ladybug buffet going. No aphids? No problem—they’ll stay for the nectar.

And don’t forget: no pesticides. I made that mistake once in my early gardening days. Sprayed to kill mites, and accidentally killed off all the ladybugs too. Heartbreaking.

What Do Ladybugs Drink?

Okay, so we’ve talked food. But what about water? I used to think ladybugs didn’t need to drink at all. I mean, they’re so tiny! But surprise—they do. And not just a little. Hydration is a big deal, especially if they’re stuck indoors or it’s hot out.

I remember once finding a ladybug inside my kitchen, just chilling on a windowsill. It looked sluggish. I figured it was just tired, but nope—it was probably thirsty. I dipped a cotton swab in water and left it nearby. A few minutes later? It was slurping like it hadn’t had a drop in days.

Natural Water Sources

In the wild, ladybugs don’t go looking for tiny water bottles. Instead, they rely on nature’s offerings:

• Morning dew on leaves (you’ll often spot them sipping early in the day)
• Rainwater droplets that settle on plants
• Plant sap (especially from damaged leaves or stems)
• Fruit juice from overripe fruits

They’re basically hydration ninjas. Just sneak in a few sips here and there while they’re munching on bugs.

What’s cool is that they also get moisture from their prey. Aphids are like little juice boxes—so when ladybugs eat them, they also get fluids.

Drinking Habits Indoors

Now let’s talk ladybugs inside your house.

If they’re flying around your bedroom or hiding in window cracks, chances are they’re dry as heck. Indoors, ladybugs might look for:

• Condensation on windowpanes
• Leaky pipes or sinks (ew, but true)
• Damp towels or cloths
• Soft fruits left on counters

But they’re not great at surviving indoors long-term. Without consistent food and water, they’ll weaken fast. I’ve learned to gently capture them with a paper cup and place them near potted plants or outside in shaded spots with a little mist. It’s like a ladybug spa day.

Pro Tip:

Want to help a dehydrated ladybug? Soak a cotton ball or a bit of paper towel with water or sugar water and leave it in a shallow container. I sometimes add a teeny bit of honey—it gives them energy and hydration in one.

But just be careful not to drown them. These little guys aren’t swimmers.

So yep, ladybugs do drink, and they’re clever about it. Whether sipping dew from a leaf or licking water off your kitchen sink, they know how to stay hydrated. Just another reason to admire them!

What Do Ladybugs Like to Eat Most?

Let’s be real—if ladybugs had a “Top Chef” menu, aphids would be the headliner every single time.

I’ve actually watched them hunt aphids on my tomato plants like tiny predators. They don’t just wander around randomly. They sniff them out, chomp down, and keep going. It’s kinda mesmerizing.

Favorite Insects and Bugs

Ladybugs are all about:

• Aphids (the #1 pick, no debate)
• Mealybugs (especially on citrus plants)
• Scale insects
• Whiteflies
• Thrips

Basically, if it’s soft-bodied and destroying your plants, a ladybug is into it.

I once had a pepper plant totally infested with mealybugs—nasty white fuzz everywhere. Released a handful of ladybugs and, I kid you not, they cleared it in 3 days.

Sweet Treats: Honeydew and Fruit

Here’s something cool: when pests are scarce, ladybugs go for sweets.

They’ll drink honeydew—a sticky substance secreted by aphids and scale bugs. It’s sugary, and ladybugs love it.

They also nibble on:

• Overripe fruit like bananas, apples, peaches
• Pollen and nectar from flowers

Sometimes, they even chill on flowers for the nectar alone. I once caught a few partying on a blooming dill plant. It was like a bug buffet.

Bonus Tip:

If you’re trying to attract ladybugs to your garden, try planting:

• Fennel
• Cilantro
• Yarrow
• Cosmos
• Dandelions

Those blooms offer both nectar and pollen—ladybug magnets!

What Do Asian Ladybugs Eat?

Here’s where things get a little…weird. Asian ladybugs (Harmonia axyridis) look like our friendly red bugs, but they act kinda differently.

I had a winter where they invaded my attic like a red-and-orange army. They weren’t aggressive to me, but they were to other ladybugs.

Dietary Differences in Asian Varieties

Asian ladybugs are:

• Opportunistic eaters
• Sometimes cannibalistic (!)
• Will eat native ladybugs if food is scarce
• Will consume ripe fruit, jam, or even leftovers

Their diet includes:

• Aphids (still a favorite)
• Scale insects
• Small beetles
• Other ladybug eggs/larvae

Household Pest Behavior

Unlike native ladybugs, Asian ones actively seek warm shelter in winter, especially inside homes.

Indoors, they’ll eat:

• Soft fruit or juices
• Leftover syrup or honey
• Dead insects

They’re also known to bite (not hard, but still) and can stain surfaces with a foul-smelling yellow secretion. I had to repaint a corner wall one year because of that!

So yeah, ladybugs aren’t always the same. Some are helpful garden guardians. Others? Wild little rebels with a taste for chaos…and jam.

Dietary Differences in Asian Varieties

• Cannibalistic tendencies
• Eating native ladybugs and fruit

• What they eat inside houses

What Do Ladybug Larvae Eat?

Alright, let me tell you—if you’ve never seen a ladybug larva before, you might actually freak out. I did. My first thought was, “What the heck is this spiky, black-and-orange alien crawling on my petunias?” Honestly, it looked like a mini alligator in bug form.

But here’s the kicker: those “aliens”? They’re baby ladybugs. And they are absolutely ravenous.

Early Diet for Growing Larvae

Ladybug larvae don’t mess around. From the moment they hatch, they’re on the hunt. While adult ladybugs are efficient, the larvae are relentless.

They mainly eat:

• Aphids (duh)
• Insect eggs
• Spider mites
• Thrips
• Tiny caterpillars (yep, the small ones are toast)

And they don’t nibble. They devour.

During one late-spring infestation on my cucumber plants, I noticed all these weird black larvae crawling around. I was about to spray them off (seriously) when I Googled a photo and realized I was about to murder my garden’s best defense force. Oops.

Turns out, a single ladybug larva can eat more than 400 aphids during its larval stage. That’s wild, right?

Hunting Skills in Larval Stage

Now here’s the fun part: larvae don’t fly, but they hunt like little tanks.

They’ll crawl up stems, under leaves, and through entire colonies of pests without hesitation. I’ve watched them wipe out full patches of aphids in just a couple of hours. It’s kind of brutal, in a satisfying way.

Ladybug larvae go through about 4 instar stages (basically growth molts) before they pupate. During each stage, their appetite increases. If they don’t get enough to eat, they won’t pupate properly or might not survive to adulthood at all.

That’s why it’s crucial, especially in biological pest control, to introduce them where prey is abundant.

Feeding Tip for Indoor Releases

If you’ve ever bought ladybug larvae to use indoors or in greenhouses (yep, you can do that), feed them immediately. I learned this the hard way.

The first time I ordered some online, they arrived in a little box with a piece of paper soaked in sugar water. I thought that was enough. It wasn’t.

You need to give them:

• Live aphids (if available)
• Freeze-dried insect eggs (from garden centers)
• Even small drops of honey water as a backup

But truthfully, nothing beats the real deal. Fresh aphids are where it’s at.

So, next time you spot something gnarly-looking on your rose bush, don’t squash it! That little monster might be saving your entire garden.

• Feeding frenzy before pupation

What Do Ladybugs Eat in the House?

Okay, so you’re chilling at home, and suddenly there’s a ladybug crawling across your living room wall. Or five of them. Been there! It always feels a little magical… until you realize they might be stuck, starving, and low-key panicking in their cute little way.

So, what do ladybugs eat indoors? Short answer: not much, and that’s kinda the problem.

Indoor Food Sources

Unlike your garden, your house doesn’t have juicy aphids just hanging out. So when a ladybug ends up indoors—especially during fall or winter—it’s usually by accident, and food is super limited.

Here’s what they might eat if they’re lucky:

• Fruit peels or juice residue on kitchen counters (like banana or apple)
• Honey, syrup, or anything sweet left out
• Dead insects (yes, they’ll nibble on those if desperate)
• Sugar water or soaked cotton balls if provided (yep, I’ve done this)

That’s… about it. No aphids, no mites, no mealybugs = very slim pickings.

I’ve tried leaving out a slice of overly ripe melon before—once, a ladybug took a few laps across the juice. Another time? They completely ignored it. Guess it depends on how desperate they are.

How Long Can They Survive Indoors?

Here’s the hard truth: not very long, unless you help them out.

Most ladybugs only survive a few days to a couple of weeks inside if they can’t find proper food or water. That’s because:

• Indoor air is dry (they lose moisture faster)
• There’s no live prey
• They often burn energy looking for light sources or trying to escape

I remember one winter when I found like ten of them near my window. I tried feeding them with sugar water and misted the window plant daily. A couple survived, but most didn’t make it. That’s when I learned it’s often better to release them outside on mild winter days, even if it’s cool out.

Rescue Tip:

If you want to help an indoor ladybug, here’s a quick DIY care station:

• A shallow lid (like from a water bottle)
• Fill it with a drop of honey mixed with water or plain sugar water
• Place a small leaf or paper towel inside so it doesn’t drown
• Mist a nearby plant or corner for moisture

Keep them near a window or potted plant to give them some “normalcy.” And if it’s warm enough? Gently escort them back outside.

So yeah—ladybugs can survive in the house, but it’s not ideal. If you find them, don’t ignore them. Give them a helping hand or guide them back to nature where they belong.

What Insects and Bugs Do Ladybugs Eat?

This is one of my favorite things about ladybugs—they’re tiny, but they eat like absolute beasts! I used to think they just munched on a few garden pests, but man, was I wrong.

Once I started actually watching them work, I realized they’ve got a whole hit list of bugs they go after. These little predators are born to hunt.

Comprehensive Pest List

Let’s dig into the full buffet:

• Aphids – Their #1 favorite, hands down. I’ve seen ladybugs mow through clusters of these guys like popcorn.
• Mealybugs – The cottony ones hiding under leaves? Total snack material.
• Whiteflies – Especially when they’re in their nymph stages.
• Spider mites – Those tiny specks weaving webbing on your tomato plants? Gone.
• Scale insects – Hard-shelled but still on the menu.
• Thrips – Very small, but ladybugs gobble ’em up when they can.
• Insect eggs – Especially from moths or soft-bodied pests.
• Tiny caterpillars – If they’re small enough, larvae and even some adults go for ’em.

I had a problem with scale insects on my lemon tree a while back. Sprays weren’t helping, and I didn’t want to go chemical. I released some ladybugs and crossed my fingers. A week later? Boom. Tree was clean. I couldn’t believe it.

Do They Eat Ants or Mosquitoes?

So, here’s a common misconception: people think ladybugs eat ants and mosquitoes. Not really.

• Ants? Nope. In fact, ants are enemies. They protect aphids because they love eating the honeydew aphids produce. They’ll fight ladybugs to keep their sweet buffet going.
• Mosquitoes? Also nope. Mosquitoes are too fast and not the kind of prey ladybugs go after.

That said, if they find mosquito larvae in very rare cases, maybe. But that’s not normal behavior.

Fun Fact:

Some species of ladybugs are specialists. For example:

• Stethorus punctillum prefers spider mites
• Cryptolaemus montrouzieri (aka mealybug destroyer) specializes in—you guessed it—mealybugs!

So, if you have a specific pest problem, you can actually choose the right kind of ladybug. Yeah, it’s like Pokémon for pest control.

So now you know—ladybugs eat more than just aphids. They’re versatile little warriors who can handle a wide range of garden invaders.

Do Ladybugs Eat Plants?

Okay, confession time—I once blamed a ladybug for chewing holes in my basil. Turns out? Wrong bug. I was so sure it was the ladybug because it was sitting right there, looking guilty. But nope, ladybugs don’t usually eat plants. So let’s bust that myth.

Myth or Fact?

Here’s the deal: most ladybugs do not eat plants. They’re predators, not grazers.

But—and there’s always a “but”—some situations might make them nibble on plant material. It’s rare, but I’ve seen it once or twice, usually when:

• Food is scarce (like in winter or indoors)
• They’re super thirsty and trying to get moisture from soft stems
• You’re dealing with Mexican bean beetles or other imposter species

Yep, some beetles look like ladybugs but are actually plant-eaters. The Mexican bean beetle (which is technically a ladybug species) is one of the only ones that does eat plants, especially:

• Beans
• Soybeans
• Alfalfa

And they don’t nibble politely either—they skeletonize leaves.

So if you’re seeing damage and ladybugs around, it’s worth checking exactly which type you’ve got.

Impact on Gardens

Now, back to real-deal ladybugs. In general, if your garden is full of:

• Aphids
• Whiteflies
• Mealybugs
• Other juicy pests

…then your ladybugs will stick to their meat-based diet. They actually help plants thrive by removing pests that suck out plant sap and spread disease.

When I started planting marigolds and dill, I noticed an uptick in ladybugs and healthier plants. Coincidence? I don’t think so.

But if you’re raising vegetables, especially beans, and seeing leaf damage, check for orange-ish beetles with more black dots than usual. It might be one of those “bad” cousins in disguise.

What to Do if You’re Unsure

1. Inspect the bug – Count the spots, note the color.
2. Observe behavior – Is it eating bugs or leaves?
3. Use a magnifying glass – Ladybug larvae look way different from plant pests.
4. Snap a pic and do a quick ID online (I love BugGuide.net for this).

Ladybugs = good. Their imposters? Not so much.

So no, real ladybugs aren’t out here munching your garden veggies. They’re probably saving them from a real pest, and maybe just grabbing a drink from a damp leaf. Give them a break—and a thank you.

How to Attract Ladybugs to Your Garden Naturally

This one’s close to my heart—because once I figured it out, everything in my garden changed. No exaggeration. I used to rely on sprays and traps, but they never worked long term. Then someone told me, “Just make your garden ladybug-friendly.” I thought, “How?” Turns out, it’s easier than you think—and way more effective than chasing bugs with chemicals.

Why You Want Ladybugs in Your Garden

First, let’s be clear: ladybugs are biological pest control at its finest.

One adult ladybug can eat 50 aphids a day, and their larvae? Even more aggressive. If you’ve got veggies, herbs, or flowers that pests love, ladybugs will save your sanity.

But you can’t just hope they show up. You gotta create an environment they love.

Plants That Attract Ladybugs

The easiest way to roll out the red carpet for ladybugs? Plant the stuff they’re into.

Here are some top ladybug magnets:

• Dill
• Fennel
• Yarrow
• Cilantro
• Cosmos
• Calendula
• Marigold
• Tansy
• Alyssum
• Dandelion

These plants provide nectar and pollen, which ladybugs use when bug prey is scarce. Plus, the flowers attract aphid-prone bugs, which ladybugs love to snack on.

I personally always plant dill and marigold around my tomato beds. And I swear, once the blooms pop? Boom—ladybug city.

Avoid Pesticides at All Costs

Let me repeat this louder for the people in the back: No pesticides. Even the “safe” ones can harm ladybugs or destroy their food supply.

I made the mistake once of using neem oil at night—and by morning, I had dozens of ladybugs upside down. Still breaks my heart.

Instead:

• Use manual removal for bad infestations (spray pests off with water)
• Encourage natural balance by planting companion herbs
• Be patient—ladybugs will show up when you’ve got a balanced ecosystem

Provide Shelter & Moisture

Ladybugs need more than food—they need places to hide and a drink now and then.

You can add:

• Small rocks or wood chips for shade
• Low shrubs or ground cover for egg-laying
• A shallow water dish with stones (so they don’t drown)
• Decaying logs or mulch piles (great for overwintering)

One year, I made a tiny “ladybug hotel” out of bamboo sticks, and they actually used it. It was wild.

Should You Buy Ladybugs?

Eh, yes and no.

You can buy them online, but:

• They’re often wild-caught (not sustainable)
• They may fly away if conditions aren’t perfect
• You still need to prep your garden first so they’ll stay

Instead, focus on creating an environment they choose to live in.

So, if you want a garden that thrives without constant pest drama, invite the ladybugs. Set the table with plants they love, give them water and shelter, and skip the sprays. Nature will do the rest.

Wrapping Up: Conclusion

So now you know—ladybugs aren’t just cute red dots on your window. They’re tiny, winged exterminators, keeping your garden healthy and pest-free. From aphids to whiteflies, from outdoor plants to indoor surprises, these little beetles are some of the most valuable allies you can have.

Whether you’re curious about what ladybugs eat, how they drink, or even what their babies chomp on, the answer usually boils down to this: They’re built to protect plants, not harm them.

Want to help them out? Plant the right flowers, ditch the pesticides, and create a welcoming home. Your garden—and your sanity—will thank you.
