Spot a ladybug, and most people assume it’s harmless and maybe even a little helpful. They’re right, mostly—but here’s what surprises even nature lovers: that bright red beetle in your garden has a secret identity. Ladybugs are voracious predators in the insect world, and what they eat (and don’t eat) might reshape how you see these tiny garden guardians.

What Types of Food Do Ladybugs Eat?
Ladybugs belong to the family Coccinellidae, and their dietary preferences reveal why gardeners actually want these beetles around. The vast majority of ladybug species are carnivorous, hunting small soft-bodied insects that damage crops and ornamental plants. According to Insect Lore (insect education resource), ladybugs primarily feed on aphids and other small pests like scale insects, mealybugs, mites, and insect eggs.
Aphids and other insects
- Aphids (primary prey for most species)
- Spider mites (useful for houseplant pest control)
- Scale insects and mealybugs
- Small insect larvae and eggs
A single ladybug can eat up to 5,000 aphids during its lifetime, according to Little Passports (educational children’s resource). This makes them extraordinarily valuable for natural pest management. Ladybug larvae are equally hungry—possibly even more so—consuming scale insects, aphids, adelgids, and insect eggs while molting four times before pupating, as documented by PEEC Nature (environmental education organization).
Ladybug larvae look nothing like adults—they resemble spiny striped miniature alligators, according to Illinois Extension (university agricultural extension). Gardeners who spot these larvae should leave them alone: they’re doing the same pest-control work as adult ladybugs.
Nectar and pollen
Not all ladybug meals involve hunting. Some species supplement their diet with nectar and pollen, particularly when prey is scarce. Carolina Biological (science education supplier) notes that pink-spotted ladybugs actively seek nectar and pollen when aphid populations dip. This plant-based behavior also helps ladybugs survive during seasonal transitions when insect prey is less abundant.
Fruits and vegetables
While wild ladybugs prefer live prey, they’ll opportunistically consume fruit and vegetable matter. Reports from Nest Bantam Earth (DIY gardening resource) indicate ladybugs consume pollen, nectar, flower petals, fruit, and some vegetable plants as alternative food sources when prey populations fluctuate.
What Can I Feed to a Ladybug?
If you’ve found a ladybug indoors or want to keep one temporarily, mealtime options differ significantly from their wild diet. Live aphids remain the gold standard, but that’s not always practical for household care.
Household foods
- Apple slices and banana pieces
- Orange slices and carrot shreds
- Raisins (soaked briefly in water)
- Brewer’s yeast mixed with wheat germ
Nest Bantam Earth reports that a mixture of brewer’s yeast, wheat germ, and water serves as a nutritious meal for pet ladybugs. For quick alternatives, apple slices, bananas, orange slices, carrots, and other fruits work adequately. One documented case from Moregeous (home and garden blog) describes an indoor ladybug that ate lettuce, water, raisins, sugar, and chicken breast—though it rejected other meats, yogurt, cheese, peanut butter, honey, and various fruits. Individual ladybugs show surprisingly specific preferences.
Overfeeding pet ladybugs can cause sickness or death, according to Nest Bantam Earth. Remove uneaten food promptly to avoid attracting other pests and spoilage that harms the ladybug.
Safe alternatives to aphids
If you’re trying to sustain a ladybug without access to live prey, spider mites make an excellent alternative. YouTube educational content confirms that ladybugs eat spider mites—a common houseplant pest—so allowing a ladybug to patrol affected plants can solve two problems simultaneously. Ladybugs also eat springtails, small spiders, fruit flies, and whitefly according to Nest Bantam Earth.
What this means: indoor gardeners can deploy ladybugs as biological pest control agents without purchasing expensive aphid colonies.
Do Ladybugs Drink Water?
Water is essential for ladybugs, but their hydration strategy differs from mammals. They don’t drink from puddles or water bowls the way other animals do.
Water sources
- Dew droplets on leaves and surfaces
- Moisture from fresh fruit
- Water droplets misted onto habitat
Ladybugs obtain water primarily through droplets they find in their environment or absorb from moist food. A few drops of water misted into their container (or a damp cotton ball) provides sufficient hydration when feeding them dry foods like yeast mixes. According to Nest Bantam Earth, ladybugs are most active in spring and summer, requiring feeding every few days during active periods—water should always be available alongside food.
Hydration from food
Fresh fruits like orange slices and watermelon contain sufficient moisture that additional water sources become less critical. For ladybugs eating dried foods or during dry indoor conditions, a small damp cotton ball placed in their habitat prevents dehydration without creating drowning risks.
The pattern: proper hydration keeps ladybugs active and healthy, but too much water creates drowning hazards in small enclosures.
What Do Ladybugs Eat in the Winter?
Winter transforms the ladybug’s relationship with food entirely. As temperatures drop and prey becomes scarce, ladybugs enter a survival state that fundamentally changes their dietary needs.
Hibernation diet
Ladybugs enter diapause (hibernation) in autumn, gathering in large groups under tree bark, in rock crevices, or sometimes inside homes. According to Little Passports, they huddle together to regulate temperature and moisture, typically waking in March or April. During hibernation, their metabolism slows dramatically—PEEC Nature reports that ladybugs can survive up to 9 months without food using fat reserves accumulated during the active season.
Indoor winter feeding
When ladybugs enter homes seeking winter shelter (especially Asian lady beetles, Harmonia axyridis), indoor conditions can create problems. Moregeous notes that central heating causes ladybugs to wake prematurely from hibernation—and without access to natural aphid snacks, they can starve. If you find an active ladybug indoors during winter, offering a moist raisin or tiny water droplet can help, but the best approach is gently relocating it to a sheltered outdoor spot.
According to Illinois Extension (university agricultural resource), Asian lady beetles were introduced to the US specifically to control aphids on crops like alfalfa. These non-native beetles invade homes in fall, bite humans, and have become a seasonal nuisance in many regions.
The catch: relocating indoor ladybugs during winter prevents premature starvation, but only if done during suitable weather conditions.
How to Keep a Ladybug as a Pet?
Ladybugs make fascinating short-term observation subjects, but they’re not suited for permanent captivity. Understanding their needs helps you provide appropriate care while setting realistic expectations.

Habitat setup
- Ventilated plastic container or small tank
- Natural twigs or leaves for climbing surfaces
- Moist paper towel or cotton for humidity
- Avoid direct sunlight and heating vents
A ventilated container prevents moisture buildup that leads to mold, while natural materials give ladybugs surfaces similar to their outdoor habitat. Nest Bantam Earth recommends a well-ventilated habitat with daily feeding for active-season ladybugs. Avoid positioning the habitat in direct sunlight or near heating vents that could accelerate dehydration.
Feeding routine
- Fresh fruit pieces (apple, banana, orange)
- Yeast and wheat germ mixture
- Small water droplet or damp cotton
- Remove uneaten food within 24 hours
Feed ladybugs every 1–2 days during active periods, providing small quantities they can consume within a day. According to Carolina Biological (science education supplier), a variety approach works best—different ladybugs show different preferences. Always remove uneaten food promptly to prevent spoilage and pest attraction.
Release advice
Ladybugs live approximately one year on average (up to three years for some species, according to PEEC Nature), but captive lifespans are typically shorter without proper conditions. The best outcome for a rescued ladybug is release to a garden with active aphid populations. Release during warm, calm weather in spring or summer when the ladybug can immediately find food and shelter.
What this means: rescue efforts succeed when keepers prioritize garden release over long-term captivity.

For gardeners discovering ladybugs in their plots, the takeaway is clear: these small beetles punch far above their weight in pest control value. Encouraging ladybug populations through pesticide-free gardening and pollen-rich plants like angelica, cosmos, marigold, dill, and caraway creates a self-sustaining defense against aphids. Rather than reaching for chemical controls, attracting ladybugs delivers long-term pest management that costs nothing and requires minimal effort.

Frequently asked questions
Can ladybugs be kept as pets?
Ladybugs can be kept temporarily for observation, but they’re not suitable long-term pets. They survive approximately one year in the wild, and captive conditions rarely match their natural habitat needs. If you find an injured ladybug, temporary housing with proper food and water is humane—then release it back to your garden when it recovers.
What is ladybug’s favorite food?
Aphids are the preferred food for most ladybug species, making them invaluable garden allies. When aphids aren’t available, many ladybugs will accept fruit like raisins, banana, or apple slices. Some species also eat nectar and pollen when prey is scarce.
What household foods can ladybugs eat?
Soaked raisins, small fruit pieces (apple, banana, orange), carrot shreds, and a mixture of brewer’s yeast with wheat germ provide adequate nutrition for indoor ladybugs. Remove uneaten food within 24 hours to prevent spoilage.
Do ladybugs eat leaves?
Ladybugs occasionally consume leaf matter, but this isn’t a primary food source. They’re carnivorous predators, though some species will nibble pollen or nectar from flowers if prey is unavailable.
What fruits do ladybugs eat?
Ladybugs reportedly accept raisins, banana, apple, orange, and other soft fruits. Soak dried fruits briefly in water to add moisture. Individual preferences vary—some ladybugs ignore fruit entirely while others readily consume it.
What do ladybugs eat for kids?
Children interested in ladybugs can offer small pieces of fresh fruit like banana or apple, along with a damp cotton ball for water. This teaches responsible observation while keeping the ladybug fed until release.
Why shouldn’t you squish ladybugs?
Ladybugs provide free pest control for gardens by eating aphids, spider mites, and other plant-damaging insects. Killing a single ladybug removes a predator that would otherwise consume thousands of aphids during its lifetime. Additionally, many species secrete a foul-smelling liquid from their joints when threatened.
What is the lifespan of a ladybug?
The convergent ladybug, the most common North American species, lives approximately one year on average, according to PEEC Nature. Some species can survive up to three years under ideal conditions. Most ladybugs die during winter hibernation or from predation.
