Where Do All The Ladybugs Come From?

Where Do All The Ladybugs Come From?

Is your house being invaded by ladybugs?

From time to time, many people write to us and ask: where do all the ladybugs come from?  They seem to be everywhere in the fall. Are they a sign of a harsh winter to come? Are they bringing good luck?

While you may have heard the superstition that ladybugs bring good luck, they don’t seem to have any weather predicting ability. There is no significance between the number of ladybugs and the upcoming winter forecast. Fall infestations of these beetles is more a sign of winter’s approach. As the temperatures begin to cool, these bugs love when a sunny day beckons to them to come out and soak up the rays. If it’s a warm autumn day, you may see tons of ladybugs on the sunniest side of your house.

As the nights cool, the bugs gravitate to warm places during the day (soaking up the sun’s rays on your house). They will do anything or go any place for a bit of warmth. In fact, if there is a tiny opening around a window or door, they find their way in and seem to invite all of their relatives.

Bottom line – the ladybugs are getting the last bit of warmth and mean no harm. And ladybugs are friends of a garden. They feed on insect eggs, small worms, aphids, and other pests. They can, however, damage carpets and furniture with their secretions. And if your home is really infested, when they die they can be all over window sills throughout the house. Best way to get rid of them? Vacuum.

Is it an Asian Lady Beetle or the American Ladybug?


Both look a lot alike and behave the same. There are a few ways to tell them apart:

  • American Ladybug: Has a shiny black pronotum (the area between the head and body) with two tiny white circles. Bodies are a dark red with black spots.
  • Asian Lady Beetle: Has a very distinctive white “W” shape on its pronotum (the area between the head and body) Their bodies are usually orange or yellowish with black spots.

    I live in Kentucky, they swarm here around late October. Some days I use a handheld Dyson vacuum sucking up hundreds a day inside the home. No exaggeration, I kept a running tally. Spending 5mins going to each window approx. 5-10x a day and persists off/on from October-March. Spent hundreds on sealing up home and exterminators. Tried everything to put a dent in the numbers. I didn’t think it could get much worse but now we have brown marmorated stink bugs too which just started last year. Good luck y’all!

  • JR says:

    I live in Hinckley, MN (about half way between Duluth and Minneapolis), Every fall about early October or so I get thousands of Asian Beetles inside the garage here are a few things I have tried.

    1) Used a professional exterminator- cost about $300, didn’t really seem to help much.

    2) Sealed up cracks and crevices and applied the same products as the professional exterminator- seemed to be less beetles around. (but could have been a “bad” year for the beetles and was coincidental that the products worked. (sort of).

    The beetles seem to get inside and just die -usually just see them clinging to the garage door or trim around the garage doors, never really see too many living beetles
    inside. I do vacuum them up with a HEPA vacuum cleaner.

    From what I read about Asian Beetles they are very difficult to completely eliminate; as you already are aware!

    They secrete a pheromone that attracts other beetles and will keep coming back year after year once they found a good place to overwinter they seem to be attracted to south facing or southwest facing structures with contrasting light-dark surfaces and before fall when they swarm they are living on the underside of leaves and soybean plants.

    The product I use to control them is Bifenthrin I/T about one ounce to a gallon of water in a pump up sprayer, I go around all the windows and doors, under eaves, window wells,foundation. It is non-staining and safe around pets after it has COMPLETELY DRIED. It mimics the chrysanthemum chemical pyrethrin and effects the insects nervous system resulting in repeated and extended nerve firings.

    It is NOT a quick knockdown insecticide.

    September is about the best time to apply it seems- probably will not completely eradicate them but should definitely reduce there numbers.

    What I do get is piles of dead beetles outside of the garage/house.

    little bugs:( don’t kill them. they have a purpose in life, to kill the pest in your plants:)

  • Evelyn Jones says:

    I have been using essential oils,: eucalyptus, peppermint, and tea oil in water. I place 5 drops of each in a spray bottle. I spray around my doors and windows on the outside and mist the window sill on inside. This has worked for me. I also put essential oil in diffuser and let it premeate my house.

  • Brad says:

    Spray…Demand CS

  • Roberta says:

    They do not like vinegar . if you spray bottle vinegar at them it will exphyxiate them.

  • Truth says:

    We should catch all that we can and mail them back to the USDA’s main oftice…really! They and the FDA like most government agencies decisions are ignorant and not well thought out.
    I see that Daddy Longleg spiders they eat them!
    I capture mine in plastic cups with a mesh top secured with a rubber band. Going to take them to a far away garden from here or call a nursery to see if they want them.
    Maybe we need to sue The USDA for importing these and those horrible Noseeums here to control fire ants from Costa Rica.I would rather have the fireants at least you can see them.
    Forget suing pharmaceutical companies for drugs sue the FDA for approving them.
    The government doesn’t care about us.Please everyone cal your congressmen and complain. Inundate their phones w calls to be sure they don’t kill us with a chemical now trying to get rid of these. Not to mention the Chemtrails that stripe the skies everyday all over the world that is a clandestine operation. If we could sue these organizations for making decisions like this that puts us in danger they will need to stop. They really think we are stupid and do see what they are doing….such evil and darkness, everything is out of balance. Maybe their decisions are made ignorantly but you can bet the bottom line is always the money.
    Peace can only be found within. What happens outside of us those making these decisons will receive back what they are doing to harm us. This life is too short to deal with these things. Love always wins.

  • Alexis says:

    The orange lady bugs bite! I always liked the little things until one night i was at my friends house and woke up to something “pinching me” (bitting me) when i woke up i slapped my neck and it was an orange lady bug. I no longer think they are cute, nice little bugs! I hate them now and are always afraid they are going to bite me again.

  • Priscilla M. Briggs says:

    I thought I was getting information on lady bugs. You know…those cute little orange beetles with black spots? They are my favorite kind of bug and I HATE bugs! Since when do lady bugs bite and stink? I used to look forward to MARCH (not October) for these creatures to hatch and make their way into my bathroom and bedroom. It was a sign that Spring was coming and everything was new and alive!

  • Stephen L Schroeder says:

    When it comes time to sell your home with this Asian ladybug problem, I have bad news for all you folks, there is not one real estate company, that will list your home if you decide on selling it. In short your home value is almost worthless and you might be “stuck” where you are now living with this Asian Beetle pest. Write your Congressman and have him/her address this problem of Asian Beetles in your area. Maybe something can be worked out by going this route. This is the BEST way of handling this problem of Ladybug infestation, due to the U.S.D.A. allowing these to be released into our country.

  • Chirpie says:

    I am in KS, there are hundreds of these things in my house and outside too! I went through every room in the house vacuuming with the shop vac, got every bug I could find. Emptied the vacuum outside to make sure they don’t crawl out back into the house. Later, still more seem to come out of nowhere on the house! I have sealed every crack, hole, gap I could find, especially around the windows, but cannot find where they are coming in! It is like they can go through walls or something magically.

    I have sucked up many colors pf these bugs: orange, yellow, an almost green color, red, brownish, and every shade in between these. Some have lots of well defined spots, some faded looking, some have no visible spots. They all fly and crawl around just the same, are the same size and shape, just all painted different. They are interesting, but it is getting old having them march around, fly a bit and die, falling on the floor. I vacuum way too much for having no carpeting in the house! Arrgh!

      I hate spraying chemicals on my house but this is the ultimate ladybeetle killer. Trust me, it solved all my ladybug problems. Dead before they can mange to crawl in your house..

  • gary says:

    the “ladybug” invasion is not what many think..it is not the signs of something you’ll find in the farmer’s almanac, the invasion is actually Asian Beetles which were intentionally imported by our government to feed on soybean mites, when the bean fields are cleared they search out new food and new places to live, (especially with the onset of cold weather). The first years of this invasion was bad, they bit, they stunk, they were thick enough in our house they set the smoke detector off. They have mated with ladybugs and are now kind of a hybrid, they don’t bite as much, or stink as bad, but they are in our house all year long. Finding a natural solution to a problem is fine, but these things are a pest that we will probably never get rid of, maybe they do a great job for the farmers, but the public should have been consulted before the government shipped these bastards here.

  • Elaine Bowman says:

    we even get them in our camper! last year over 250 oh these little buggers.. vacuumed the house and the camper numerous times.. and yes they are here right now..never knew they bit though.. but they do sometimes smell like a potato… just sayin.

  • unclebuck says:

    But I also read that there are more of the Asian Tiger Beetle than the Ladybug?????

  • Sheila says:

    They got in our country house last year. It was our first experience with these bugs. We went for a visit there and got there very late and thought oh well we will deal with them in the morning since we were so tired from the drive. That was the wrong thing to do. We turned out the light to go to sleep and as soon as we did one flew down and went right into my husbands ear! He jumped up and was swatting at his ear. I looked in there and there it was. One of those beetles. We thought we were going to have to go to the ER to get it out. They directed me to a nurse hotline and she told me to have him turn the ear that had the beetle in it up and shine a flashlight on his ear. The bugs always crawl up! Don’t kill them if they get in your ear or that’s another fiasco! I was so thankful when I saw it crawl out of his ear! Just thought I would let everyone know just in case this ever happens to you! We eventually got to sleep at 3:00 am. Ha!

  • penny says:

    i find if you clean up your leaves before winter around the house the next year you won’t have as many.

  • Viki says:

    Trying to stain the logs on our home has been almost impossible. Buying time against cold weather coming in too. Frustrated with these buggers. Sprayed myself with bug spray, didn’t make any difference, awful smelling stuff but they land on me anyway. Not too safe on a ladder. Told my husband that if I fell and knocked myself out they would swarm and eat me. Zombie beetles, ladybugs, whatever…

  • BiC says:

    Beetle traps did not work for me, so I used bug spray on the outside of my home- Ortho Home Defense Max Insect Killer. It helped. I sprayed the following: front door, around windows, garage door, porch columns, porch ceiling, fascia… basically the porch in its entirety and around all windows and doors. Be aware of the direction of the wind so it does not come back at you. Be aware if you have pets that lounge on the porch. If you can safely reach them, I would advise spraying any attic vents.

  • MaryLu Cloutier says:

    Here in rural area of Northern Illinois, these Asian Beetles (not ladybugs) swarm by the millions in the sun and on sides of houses. This is in late October. At night you can hear them in the walls and it sounds like humming static. One night while sleeping, one or more got stuck between my chin and neck and gave me some bites that oozed, itched, and lasted for weeks. I am very careful to search and destroy these pests in the house but they have pretty big armies!

  • Hilary says:

    Farmers Almanac, I am disappointed in you. Surely, you should know the difference between ladybugs and Asian beetles? !

  • Lyn says:

    These are Asian beetles, NOT lady bugs, NOT stink bugs. They are disgusting and a BIG nuisance at my home in Somerset County, Pennsylvania. Ridding your home if this pest is near impossible. Even calling the exterminator doesn’t seem to rid my home sweet home of them. We’ve tried bombs too. Nada. Zip. Zilch. Nothing has worked thus far! The handful of folks on here chanting praise of this beetle bug from hell clearly are insane or are not as infested as those of us going batty over them in our abodes. I read someone said lemon Pine-Sol works and citrus spray. I’m ready to buy a tanker truck full and hose down every square inch of this place!!! Oh and before I end my rant, the simple suggestion of vacuuming them up is hilarious!! I will pay you good money to put a vacuum on your hip and tend to these beetles in my home. That is stupid, rude response to us folks who want our homes pest free, clean and beautiful. I vacuum daily, sometimes 2-4 times a day. My home is beautiful and even with three children amazingly well kept. I’m to the point of selling and moving! If the option of ‘vacuuming’ worked none of us would be online searching for help. Kindly keep your ‘save the planet’ advise for some other topic.

  • jaden cain says:

    I live in Kentucky and I have noticed them every where, they are all over the columns on the front porch, their on the windows! Every time I try to go outside they fly in my hair 🙁

  • Deb Capell says:

    We were inundated years ago by them at our 1870’s weekend home (surrounded by fields). They would parade across the ceiling beams, be in the beds, on two floors everywhere! We hired an exterminator to spray in the fall and the result has been amazing. Still a few, but nothing like previously!

  • elaine rivet says:

    If these
    Asian beetles are imported, has anyone done an online lookup to see how the people deal with them in the land they came from?

  • Brickhouse says:

    My grandson has named me as ‘Lady Bug Grandma’ to differentiate from his other grandma because I have so many ladybugs in our historical brick home. We picked many up out of the window sills and off the floor. When I asked him what I should do with them, his response was,”put them in the toilet so I can pee on them!” Apparently he had been practicing his aim with round oat cereal at home!

  • Ellen Watkins says:

    You would think that by now the government would know better than to import an insect species to help with an infestation of another species. If they would leave these things alone, nature would take care of itself. They only have to look into past records and see what has happened when they tried similar things before. Instead, they are too quick to make decisions that have dire consequences which we have to deal with for years and years. And these people are suppose to be experts. What a bunch of dummies.

  • Velva says:

    I am really over run with these beetles again this year. I googled how to get rid of them..i read to use a citrus spray. I bought lemon spic and span and sprayed all the window sills and floor on all the outside walls. It worked. Also used the orange cleaner..

  • Anita Raymond y says:

    When my granddaughter was about 5, she brought them into their house so they wouldn’t get cold in the winter. Of course many were making it in on their own

    When my oldest granddaughter was about 5, she brought them into their house so they wouldn’t get cold. Of course plenty were making it in on their own.

  • Mel says:

    I live in Northern New Brunswick and so far I have only seen 1 ladybug and that was earlier today,I have never had a problem with them inside my home but in past years I have seen hundreds on the siding all around my house, Some say they are bringing good luck, cant hurt to believe I guess 😉

  • If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
