Got A Ladybug Infestation? Here’s What To Do If Ladybugs Are Invading Your Home

If you’re trying to find ways to deal with a ladybug infestation inside your house (like I’ve done each of the past 6 or so years), then you’ve come to the right place!


Ladybug infestations typically consist of the orange and black variety of ladybugs (Asian lady beetles), rather than the bright red ones with black spots.

The following tips apply to any type of ladybug that may be invading your living space.

A new imported species, the multicolored Asian lady beetle, likes to spend winters at lower elevations and our houses happen to be very handy. If they gain entry they can be a pest all winter. They do no direct harm but some believe they contribute to indoor allergies and they can be very messy.  Source

See why ladybugs (especially Asian lady beetles) invade your home in the first place, and what you can do to prevent or control a ladybug infestation inside your house each fall…


Why Are There So Many Ladybugs In My House?


Asian lady beetles like to hibernate each winter inside a nice warm house. That’s why most ladybug infestations occur during the fall months.

As it turns out, the ladybugs are attracted to light colors, including the color white.

They’re also attracted to warm, south-facing rooms.

So, chances are each fall ladybugs will find their way to the light-colored walls on the south side of your home.

The ladybugs come in through small cracks around windows, door ways and under clap boards. They want to hibernate in a warm, comfortable spot over the cold months of winter. Ladybugs gather in groups when they hibernate, so if you see one, you can be sure more will follow. The best way to keep them out is to repair damaged clap boards, window and door trim and to caulk small cracks.  Source


In my case, the back side of our home has light gray vinyl siding. Furthermore, the window frames, doors, and door frames in my home are indeed white. Each fall we find hundreds of ladybugs flocking together inside our house.

Usually, the ladybug infestation begins in our kitchen (where the walls are a pale light yellow) and dining room (with light sage green walls). Both rooms are on the south side of our house. Mostly, the ladybugs hang out in the corners of our ceilings, along the windowsills, and around the door frames.

Can Ladybugs Hurt Anything In My House?

While ladybugs are adorable and even thought of as good luck charms, their winter migration is usually so massive that their cuteness quickly fades once homeowners realize that their homes have been invaded by them.

The good news is the ladybugs don’t eat anything or lay eggs inside your home.

Once they find their way out, they’re gone for good. Typically, that’s springtime. Of course, several will simply die inside your home while waiting for spring. Other than leaving their unsightly carcasses behind, they’re harmless.

Ladybugs don’t eat fabric, plants, paper or any other household items. They like to eat Aphids. Aphids are very small, but very destructive pests that feed on plants. Ladybugs, while trying to hibernate in your house, live off of their own body fats. They, also, prefer a little humidity. But our homes are usually not very humid during the winter. In fact, they are rather dry causing most of your ladybug guests to die from dehydration.  Source


How To Get Rid Of Ladybugs

ladybug-infestation-by-saaby.jpg Simply vacuum up any ladybugs you find around the house (either dead or alive). Then, empty your vacuum cleaner bag. If live ladybugs are left to decay inside your vacuum, it will start to smell.

Or, to prevent the ladybugs from going into your vacuum bag altogether, simply insert the leg of a pair of pantyhose (about 8 inches, starting from the toe) into the hose of your vacuum cleaner. Secure in place with a rubber band. The best place to put this is between 2 sections of hose. Then, vacuum up the ladybugs. (They’ll all be contained within the pantyhose.) Finally, tie off the pantyhose with rubber bands and discard.

Disturbing them will only cause them to stress out leaving yellow markings on your walls. The yellow stuff, you see, is not waste matter, but rather, their blood. Ladybugs release a small amount of their blood which is yellow and smells, when they sense danger. Some people have said that it does stain on light colored surfaces. Source

As an alternative to the vacuum method, here are some eco-friendly and ladybug-friendly methods of controlling a ladybug infestation, including making a quick & easy ladybug condo for the winter months.

Reasons To Appreciate Ladybugs

As it turns, out ladybugs are very helpful insects.

They feed on aphids (or scale insects) — which are insects that can do measurable damage to your foliage and garden.

Aphids thrive on the new spring growth of young trees. When they infest a tree, the leaves will shrivel and curl placing the tree at risk. Aphids are like candy for ladybugs. So without the use of chemicals, they will munch away and clear out an infestation very nicely.

While on their search for edible and destructive bugs, ladybugs will do no harm to your plant life or any pets or animals they may come in contact with. All in all, this cements the fact that ladybugs are good bugs.

    Great article. I’ve been having the same issue this winter in our new home. Thanks.

    actually they weren’t even effective at eating aphids! some scientist’s bright idea proved unsuccessful. Now there is this mega proliferation…they have no real predators…even chickens don’t really like them…and they have crowded out the native species of lady bug. i also always thought they smelled like rotten lettuce. The walls in our old house are crawling with them. At night they all go to the light you have turned on. You vacuum hundreds up and 10 min later they have been replaced…super unpleasant. if you open your window (w no screen) in the spring they will eventually find their way out. hopefully some native species takes a liking to them.

    Not all ladybird beetles are non-native. I looked very closely at mine (with insect ID book in hand) and many of the ones in our house are native. I like to HUMANELY collect them and release them outdoors, where they can overwinter naturally under leaf litter and such. Much better then slowly killing them. If you have an infestation in your house you obviously have some leaks, which can be patched up before fall (much more energy efficient, too).

    bug_lover question – will the ladybugs find their way out on their own? I work in an office building thats been infested with the asian lady bugs (as well as stink bugs), and I always take the time to bring them out in the spring. just wondering if this was a waste of time (given that my goal is to help them out!)

    • FunTimesGuide

      doug207 – in my experience, the ladybugs do not typically find their way out on their own. I can’t tell you how many dried up ladybugs I’ve had to sweep up after finding them in hidden corners and on window ledges in rooms that we don’t use.

        Lol well I escorted mine out yesterday, sorry im helping proliferate this pest bur they’re not too bad and I bonded with him all yesterday morning as he walked across my computer screen, I just felt like I had to give him a chance
