It turns out that these tiny spotted bugs are aphids, tiny sap-sucking insects that can wreck havoc on your indoor and outdoor plants, like hungry, hungry hippos. If you have an aphid infestation, lady bugs can be a helpful ally because they can consume up to 5,000 of them in their lives.
According to Cory Tanner, team director of the horticulture program at Clemson University, lady beetles are a vital component of a healthy outdoor environment that, under some circumstances, aids in the management of aphid populations.
Thrips, mealybugs, and various scale insects are just a few of the soft-bodied invertebrates that lady beetles and their larvae will eat.
More than 5,000 different species of ladybugs exist worldwide, and different varieties can assist control a variety of pests: “Lady beetles come in a variety of species,” adds Tanner.
Some insects, such as the multicolored Asian lady beetle, are generalist feeders, which means they will eat a variety of insect species, but other insects have a focus on a specific subset of insects.
There is no doubting that having these bugs around your yard is beneficial, but inside your house? That is a unique situation.
Which indoor plants consume ladybugs?
Small oval-shaped flying insects known as lady bugs have six tiny legs and antennae. However, given that there are thousands of distinct kinds of lady bugs scattered over the world, colour can vary greatly. to the recognizable red beetle with black dots, from little to no color at all.
If the lady bugs you released are content in their new surroundings, they can start reproducing. Ladybug eggs are recognizable by their orange color and spheroid (football) form.
What Pests do Lady Bugs Eat?
Because they consume other insect species, lady bugs are regarded as predatory insects. They are excellent plant defenders because they are well known for consuming common plant pests like aphids. It is understandable why lady bugs are commended for their ability to manage pests given that they may eat about 5000 aphids in their lifetime as adults.

I demonstrated how to manufacture natural plant insecticides last week. These sprays deprive your plant of beneficial insects like ladybugs while yet posing less of a risk than the harmful ones. Ladybugs live up to their cute little name, unlike the majority of obtrusive insects that you wish to get rid of from your garden. Because they eat some of your plants’ nemeses, such aphids, mealybugs, leaf hoppers, scales, and mites, they do no harm and are even helpful.
There are several plants you may produce to assist attract ladybugs because they also seek out pollen as a food source in addition to insects. The ladybug can be attracted by flowers and herbs like coriander, dill, fennel, caraway, yarrow, tansy, angelica, scented geraniums, coreopsis, and cosmos.
Consider purchasing ladybugs to release in your garden if you’re still having difficulties luring the little critters there. Yes, you can easily get them online or at the majority of specialty garden retailers. Numerous stores can be found with only a quick search. It’s a good idea to buy more than you need because they won’t all stay in your garden. Hippodamia Convergens are the ideal species of ladybug for gardens. The two white spots on the backs of these ladybugs, located above the wings, give them away. The native ladybug Harmonia Axyridis is chosen over the Asian kind because it can quickly consume large numbers of aphids. The Asian ladybug, a non-native species that likes warmer climates and is the main culprit in ladybug infestations inside the home, is particularly successful at controlling aphids.
Follow the directions provided with the ladybugs when it’s time to release them in your garden to increase the likelihood that they’ll choose to make it their permanent home. Additionally, you may create the simple ladybug feeder pictured above to further attract these useful insects to your yard.
Instructions
1. Collect your supplies and equipment.
2. Take bamboo measurements. My rating was 10.
3. After you’ve made your mark, draw a line with your pencil that taper-offs at an angle. This will act as a makeshift umbrella to protect your ladybug feeder from the rain.
4. Cut the line at an angle with your saw, taking care not to spill any bamboo.
5. Repeat step 5 on the other end, and you’ll have the finished bamboo. You can use a piece of sandpaper to gently sand your ends if they are particularly pointy or jagged.
6. Drill holes that are just a little bit larger than the twine you’re using.
7. Thread the ends of the twine through the openings, then tie a double knot on each end.
8. Hang your ladybug feeder, then fill the bamboo feeder with a few raisins. If there aren’t enough aphids or other insects, the raisins will entice ladybugs to the feeder and feed them.
9. Because my rose bushes are infamous for attracting aphids, I decided to hang my near a food supply by mounting my feeder on a hook between them.
Additional Information: Your twine should last the entire season, but you should consider replacing it every year.
Do ladybugs hurt indoor plants?
Hello Mike, A few years back, I heard that praying mantises and ladybugs were beneficial for gardens. Is this a fact? If so, do let me know where I may acquire them. Thanks.
— Dave in Chestnut Hill, Pennsylvania
A. Dave, we hear this question a lot. The beautiful insects known as “beneficials” are those that only eat landscape pests and don’t affect beneficial insects or plants. Ladybugs undoubtedly come into this category, but not in the sense that most people believe.
The spotted red “ladybug” that we are all familiar with is actually more properly known as a “lady beetle” or “ladybird beetle,” as these insects are true beetles rather than bugs. While it does occasionally eat aphids and other soft-bodied pests, in its adult form it doesn’t actually consume that much food. The larvae of ladybugs are ferocious predators of soft-bodied pest insects, particularly aphids. The appearance of this helpful ladybug baby should be familiar to gardeners who are troubled by those sap-sucking perfidious pests (i.e. rose growers), else they could try to destroy the spiky, frightening-looking, alligator/dragon-like animals.
And ladybugs are available through mail order. However, it’s crucial to release them properly, or else they’ll all take off. Even though there are countless varieties of ladybugs, such as one that is tiny and jet black and one that is blood red with no spots, only the common “Convergent Lady Beetle” (Hippodamia convergens) is sold to householders. These are gathered from places where animals hibernate throughout the winter, which is acceptable because it has been done for many years without having an adverse effect on the animals’ population.
The women must be released into a soggy garden that has aphid issues in the evening after they arrive.
They will all fly away if you release them onto a garden without any aphids for the young to consume.
However, they can’t fly at night, so releasing them right at dusk ensures that they will stay the night. They’re thirsty when they arrive, so a garden that you’ve created drenched in water before releasing them will provide them plenty of chances to quench their thirst and let them believe that this site has some potential. Many of the women will determine that this garden is an excellent spot to spend the summer if they come across aphids when they are drinking and exploring it. The eggs, which are ovals that are yellowish-orange and laid on the undersides of plant leaves, should not be destroyed. Instead, be kind to those frightening-looking youngsters.
With a three-pronged approach, you may also draw local ladybugs and many other useful insects.
- Use no chemicals at all on your garden! (I like to say that!)
- By adding stones and water to saucers, you can create suitable water sources. The little insects can drink and perch on the pebbles without worrying about drowning like they could in a large birdbath.
- Grow plants with tiny blooms that produce nectar and pollen that adults can quickly access for a quick sugar boost.
A wonderful approach to do #3 is to plant twice as many culinary herbs as you would ever use in your cooking. As you would normally do when harvesting herbs for the kitchen, constantly pinch back half of the plants to keep them from flowering (when herbs flower, their flavor frequently changes, and always for the worse). However, leave the other half of the plants to produce the tiny flowers that are so alluring to beneficials. The absolute best options are dill, fennel, and caraway; moreover, cosmos, marigolds, and tansy (that is, the herb Tanacetum vulgare, not the poisonous weed known as tansy ragwort; for more information on this intriguing and practical plant, read our previous Question of the Week on ants).
There will be a lot of additional benefits from this plan. Like the lovely lacewing, a delicate-looking flyer whose young resemble ladybug larvae in appearance but are even more adept at devouring those persistent pests of roses and other plants—so much so that they go by the nickname “aphid lion”! In addition, you’ll draw Braconid, Trichogramma, and other little wasps. These tiny, almost visible animals don’t care about people; instead, they lay their eggs within or on top of nuisance caterpillars, parasitizing and killing them while, of course, producing more wasps that control caterpillars. (The frequently observed white “spines” on tomato hornworms are actually Braconid wasp eggs.)
With excellent results, lacewings and mini-wasps can also be ordered via mail. The little containers, which are typically sent at the egg stage, should be placed in a safe, shaded area of the garden. The adult wasps will come out to regulate the caterpillars, and the aphid lion lacewing larvae will hatch and search for aphids. (Obviously, place their pots next to the plants that are having issues; keep in mind that they need some bugs to feed on to survive.)
Other helpful insects like damsel bugs, big-eyed bugs, tiny pirate bugs, and assassin bugs (which attack adult Japanese beetles!) will also be attracted by the water, pollen, and nectar. Soldier bugs with spines, syrphid flies (which resemble bees but hover like hummingbirds), and tachnid flies are among examples. Learn about these critters’ appearances online before trying to kill your spined army bugs, which resemble stink bugs (the good guys have shoulders with sharp points), or tachnid flies, which resemble houseflies (the good guys have bristles, and fly in a very un-housefly-like manner).
How about the legendary praying mantis? Because they will devour any bug they can catch, including beneficial ones, these remarkable creatures aren’t actually helpful. Now, if a few of them show up in your garden, leave them alone because they’re a part of nature, entertaining to watch, won’t harm your plants, and will help you by getting rid of some pests. However, I strongly advise against ordering them through the mail because many scientists believe that once they are released, those non-native mantises will fight and eradicate the native variety. Why Do Ladybugs Live in the Extra Bedroom I Have? Furthermore, what should I do with them?
Question Hello. I am very aware of how beneficial ladybugs are as predators. But every autumn, they all seem to want to enter my house. They sometimes cover the ceiling in my sunroom. Would putting a ladybug house in my garden help stop this invasion? Missouri’s Ursula
Can you do anything to get rid of ladybugs? They are all on my uncle’s back door and everywhere else! I’m grateful. —- in Delta, Pennsylvania, Wanda (a small town on the Mason Dixon line)
Answer. Every year around this time, I get a ton of queries about these pest-eating gals, who are typically multicolored Asian lady bugs that invade homes (or Ladybird beetles, if you must be technical about it). They were considered to have died out and been a failure when they were imported and released in the past to fight a nuisance they naturally ate back home in the Orient.
They then started showing up again in large numbers, but at private residences. They congregate on South-facing walls of light-colored homes in the fall to stay warm, and then they start seeking for cracks or other entry points so they can spend the winter hibernating inside, just like they did in caves back home. In order to save heat for the winter, it is not uncommon to see hundreds or even thousands of people huddled together in a high bedroom corner on the second floor. Typically, I have recommended two things. One, be grateful that they discovered the gaps in your insulation because if they do, your priceless heat will escape. ( “We are what? The street being heated? “) Close the window where they entered more tightly, fix the weatherstripping, or caulk the area.
After that, I’ve been advising folks to vacuum them up into a clean bag with some shredded leaves or raffia, mist it thoroughly, store it in the refrigerator, misting it occasionally until Spring, at which point they should be released into the garden. But since they can’t break into your house, I pondered where and how they spend the winter. IS it okay to vacuum them and store them in the refrigerator? or outdoors? Is that correct, Mother-May-I-Correct? Am I? Was I?
As a result, I grasped the chance to contact Dr. Linda Gilkeson, a beloved insect expert who used to work for the Canadian government as a beneficial insect specialist but is now a private I PM Consultant and resides on Salt Spring Island in British Columbia.
She says that all species of lady beetles hibernate indoors or outdoors when they reach adulthood. Some women like to slither their way into caverns or colonials, especially Asian women (you can tell them apart because nearly no two look similar). All ladybugs attempt to slink into some sort of crack, crevice, or other sheltered location for the winter, and native species will even enter your home if they can.
Linda, apologies, Doctor Linda believes that is “getting them back outside for the winter is crucial. They will swiftly exhaust their body reserves needed for the winter indoors due to the warm, dry circumstances, and will perish in large numbers. They can be transported outside, where the cold keeps their metabolism slow until spring, and can be swept up or vacuumed using a tiny hand-held vacuum.”
I queried her opinion of my suggestion to store them in the refrigerator with a gentle misting till spring. She claims that it MAY succeed, but “only if they are adopted by a family of devoted lady beetle-o-philes who will prioritize their care until spring. If someone makes a mistake and is allowed to dry out, they will pass away.” She continues, saying that most refrigerators “keep the air dry as part of the defrosting operation,” and that it might not be reasonable to expect customers to remember to supply moisture consistently throughout the winter. And the opposite is just as awful, she says: If they get too damp, they might pass away from a fungus, especially if they’re all packed in close together like they usually are.
However, there is a third choice. If, like me, you bring a lot of plants inside for the winter, you might not be able to get every last aphid off (hey, I was busy, OK? You can attempt to gently re-room some abducted women to perform some aphid eating for you (What are youacop?!).

Wait till it is dark outside before thoroughly misting the plants. Spread the women out on the soggy, pest-infested plants after turning out EVERY light in the space. They are really thirsty and won’t be able to fly away in the dark. Ideally, they’ll search the plants for that water, come upon aphids, and act naturally. Good for your plants, bad for the aphids. For as long as you can, keep the room as dark as you can because they will congregate near lights. Therefore, tape over electrical outlets and screen off light fixture entrances if you can.
Linda cautions her “We employed lady beetles in a solar greenhouse to manage aphids. When fall arrived, the beetles literally retreated into the woodwork and, most inconveniently, into the electrical sockets, causing us to be unable to plug anything in all winter without crushing bugs. The greenhouse turned extremely cold in the winter.”
And those homes, which I’ve always imagined were equally useless to butterfly homes? “They can be wonderful garden ornaments, but lady beetles wouldn’t find them any more alluring than any other painted hollow piece of wood, she claims. In locations with foliage, mulch, rockeries, and barns, beetles overwinter. You’d be shocked at how many lady bugs spend the winter in one of my garden beds where I personally cut my corn stalks down and spread them out.
Native species like to overwinter in the hollow centers of plant material like corn stalks and bamboo stakes, despite the fact that the multicolored Asian ones do appear to be hunting for structures that remind them of rocky outcroppings, she says.”
