Ladybugs can be beneficial to your yards and gardens, but some species can also be a big nuisance. In this blog, we talk about how to get rid of ladybugs that try to invade your home.
Typically, ladybugs or lady beetles are seen as beneficial insects since they eat garden pests.
However, some of them can quickly become a nuisance if they start to infest our homes, which they often do during the winter.
So, getting rid of ladybugs from your house as soon as possible is essential. To learn why we must remove them from our homes and how to do it, continue reading.

Why Are Some Ladybugs Unwelcome?
A ladybug infestation can cause unwanted stains on several household items, including walls, paper products, and curtains.
Their presence can also lead to odor issues since they secrete a yellowish-brown fluid with an unpleasant odor when threatened.
Lady beetles who infest houses are also more likely to bite human skin than those in gardens. Even though their bites are harmless, they can still cause discomfort for a while.
Thankfully, not all ladybugs do these things. Let’s first understand which ones can be a problem.
Types of Ladybugs
There are more than 5,000 species of ladybugs around the world, but only about 450 in North America. There are some that have traveled to the states, most notably, the Asian lady beetles.
Both ladybugs look the same – red and round with black spots on their back and a white lining on the head.
However, by nature, they can be very different from each other.
Asian Lady Beetles are more aggressive than native ones and often overstep the boundaries of the gardens they are supposed to belong to. Let’s learn about both in more detail.
Native Ladybugs
The red and orange native ladybugs are round, with black spots on the back and white markings on the head.
Their snout, however, is less pointed or sharp than Asian lady beetles, but the latter have white spots on their cheeks.
Native ladybugs spend the winters outside and consume garden pests without congregating in large groups. They are, thus, truly beneficial insects to humans and nature.
Asian Lady Beetles
The Asian lady beetle, also known as harlequin ladybirds, can be spotted in yellow, tan, orange, and deep red shades.
They come with many black spots or none at all, but you can easily recognize them due to the ‘M’ or ‘W’ marking on their head.
It is visible in a white-colored marking and might be a little faded sometimes, but it’s always there.
Their oblong-shaped body is larger than the native species, and their mouth is a pointer or sharper than most ladybug species.
They can undoubtedly bite if provoked or threatened.
This ladybug species usually overwinters inside people’s homes and can show up in large numbers (thousands of them).
They can quickly be a nuisance to homeowners. They also secrete a yellowish-brown fluid that smells nasty and leaves stains on household items.
While they eat many pests like aphids and mites, they often start munching on beneficial insects also, especially when aphids are scarce.
As we said earlier, these ladybugs can collect in large numbers, and they often overeat the resources that native ladybugs were also feeding on. They can become a significant problem for native ladybugs.
Many people also have allergic reactions when exposed to dead Asian lady beetles.
All in all, you need to eliminate them from your house.
Ways To Remove Them
As discussed, native ladybugs are beneficial to humans, so having them around and in your garden is great.
However, if you notice a large group of Asian ladybugs swarming your house, especially during colder months, getting rid of them is the only solution.
Here’s a list of some quick and easy ways to get rid of these ladybugs.
Vacuuming
The easiest way to get rid of ladybugs in your house is to suck them in a sealed plastic bag via a vacuum cleaner and discard the bag outside the house.
Make sure to use a shop vac instead of a regular vacuum because these bugs can always escape if they are not sealed off.
Vinegar
White vinegar can successfully kill the ladybugs in the house and remove the pheromones they release to attract their males.
All you have to do is pour white vinegar into a spray bottle, look for the bugs in your house, and spray it directly on them to get rid of them.
Soapy Water
Soapy water is another one of those catch-all remedies for insects, and it works equally well for ladybugs too.
Pour water and soap into a bowl, mix them and leave the bowl in a well-lit area. These bugs are attracted to light and moisture so that they will land in the water.
However, the soapy water solution will not allow them to leave. You can then pour the water outside of your house.
Insect Traps
Lady bugs are attracted to light, so it is a good idea to set up insect light traps in dark and enclosed areas, such as the attic or basement.
All you need to do is purchase an insect trap and keep it in a lighted area, or make one yourself at home and finally put it in the infested area of the house.
Once you do, sit back and wait for the bugs to appear. When enough ladybugs are trapped in it, take it out and release them.
Diatomaceous Earth
DE It is a type of sedimentary earth (silica) used as a natural pesticide.
When sprayed on ladybugs, it dries out their exoskeletons until they die. You can use a vacuum cleaner to take them outside your house after they are dead.
Planting Mums
Plant mums are famously known for removing ladybugs and insects from the house. You can put the mums on your home’s windows, doors, or other entry areas to block these bugs from getting in.
The good thing about these flowers is that while they effectively help remove ladybugs from the house, they do not cause harm to animals or human beings.
Bay Leaves
Bay leaves and cloves, lavender, and citronella help humans get rid of ladybug infestations inside their houses. It is usually their smell that keeps the bugs and insects at bay.
Insecticides
If you are not looking for natural or homemade ways to get rid of ladybugs infestation during cold weather, you can choose chemical repellents, aerosol insecticides, or sprays to remove the bugs.
All you have to do is target the bug with the nozzle and spray the chemical directly at the bug. However, you must make sure to read and follow the instructions in the package before using the product.
Once the bug is dead, you can use a vacuum cleaner to suck it in and discard the insect outside your house.

How To Prevent Them From Swarming
If you want to prevent ladybugs from swarming, simply don’t allow them to enter your home! Here are some tips to make that happen
- Seal all the cracks, crevices, and holes you find across your house, especially those on entry zones like doors, windows, etc.
- Install good quality screens over roof vents because that’s one area most people miss and, thus, suffer later.
- Always check your window screen for any dents; if found, get them fixed immediately, especially during winter.
- Spray white vinegar or insecticides around the house to get rid of the ladybugs as soon as possible.
If you cannot get rid of them even after following all the guidelines, get professional help.

First larvae should be Coccinella septempunctata and second one belongs to Propylea quatuordecimpunctata.
Thanks so much for the identification Mardikavana. We will search for some links to other images on the internet and update the posting.
Actually both seven-spot ladybird and 14-spotted ladybird are widespread in Paleartic ecozone and thus can be found in Europe and Asia.
The depicted imago on the lower picture is not seven-spot ladybird. Are there more photos of that ladybird imago?
