In nature, lady beetles eat other insects and have chewing mouthparts. The bite feels like a pinprick and is seldom serious. Asian lady beetles are also becoming a concern of the wine industry. Due to their noxious odor, even small numbers of beetles inadvertently processed along with grapes can taint the flavor of wine. People's reaction to lady beetles varies widely from tolerance to revulsion. The following management tips are provided when the beetles become a serious nuisance within a dwelling.
Once the beetles are indoors, the easiest way to remove them is with a vacuum cleaner. If you later wish to release the beetles outdoors, place a handkerchief between the vacuum hose and the dust collection bag to act as a trap.
A broom can also be used, but is more likely to result in staining when beetles emit their yellowish defensive secretion. Sealing cracks and openings is the most permanent way of preventing lady beetles from entering buildings. The time to do this is in late spring or summer, before the adults begin flying to buildings in search of overwintering sites. Cracks should be sealed around windows, doors, soffits, fascia boards, utility pipes and wires, etc.
Larger holes can be plugged with cement, urethane foam or copper mesh. Repair damaged window screens and install screening behind attic vents, which are common entry points for the beetles. Install tight-fitting door sweeps or thresholds at the base of all exterior entry doors. Gaps under sliding glass doors can be sealed with foam weather stripping.
These practices will also help prevent entry of flies, wasps, crickets, spiders and other pests. Some householders may find it more practical to hire a pest control firm, building contractor or painter to perform these services For more on this topic see University of Kentucky entomology fact sheet, How to Pest-Proof Your Home.
Indoor Treatment - Insecticide foggers, "bug bombs" or sprays are generally not recommended for eliminating beetles indoors. Insecticides applied indoors for lady beetles tend to be ineffective and may stain or leave unwanted residues on walls, countertops and other surfaces.
A vacuum is more sanitary and effective. Attempting to kill beetles hibernating in wall cavities and other protected locations is seldom effective. A better approach is to take preventive measures to reduce beetle entry in subsequent years. Exterior Barrier Treatment - While sealing cracks and openings is a more permanent way to limit beetle entry, the approach is time-consuming and sometimes impractical.
There can be countless cracks associated with eaves, siding, vents, etc. On multi-story buildings, sealing becomes even more difficult. If lady beetles are a perennial problem, owners may want to hire a professional pest control firm. Many companies apply insecticides to building exteriors in the fall, which helps prevent pest entry.
Fast-acting residual insecticides can be sprayed in a targeted band around windows, doors, eaves, soffits, attic vents, and other likely points of entry. Some of the more effective insecticides used by professionals include Demand lambda cyhalothrin , Suspend deltamethrin , Talstar bifenthrin and Tempo cyfluthrin.
Purchasing these products in concentrated dilutable form will allow larger volumes of material to be applied with a pump-up or hose-end sprayer. To be effective, barrier treatments should be applied before the beetles enter buildings to overwinter. In Kentucky, the proper timing for such treatments is typically late-September to early October although this will vary with seasonal conditions.
During late winter or early spring, barrier treatments are ineffective since the beetles gained entry the previous autumn.
Other approaches have been suggested to alleviate problems with Asian lady beetles. Ladybug "houses" sold in garden supply catalogs will have no effect in keeping the beetles out of your home.
While they are mainly harmless, sharing air space with them in a confined area like a home or office can cause allergic reactions. Now I get allergy shots to manage the symptoms because they keep coming back. They are outside and now wasps are coming on the porch. I just rid my screened porch of many ALBs by putting dish detergent in water in an old ice cream bucket. I flicked the little buggers Wear a glove if you are squeamish. This is the same method I use during Japanese beetle season outdoors.
Thought they were brought in. We either vacuum them or scoop them into an empty water bottle. Recently, we started adding a little water and Dawn to the bottle and noticed the liquid is killing them. Thanks for the tip. If I do locate some and try, will repost results.
Happy killing! Can you please reply back to this? This has happened several times this year. Where do they come from? I sleep on the bottom of a bunkbed. How are they getting into my room?
I have a fear of all insects, even ladybugs. Please help me! Hi Gretchen, I empathize with you. Bless your heart. I feel this way about spiders. Get a spray bottle and fill almost full with water. Add a strong essential oil can be purchased online or at health food stores about 30 drops. Peppermint oil works well and you can add cinnamon and cloves for a nice wintry smell.
Use lemon and orange oils in spring and summer. Shake well before spraying. Spray directly on the bugs when you see them and spray around your windows. It is toxic to bugs and will make your room smell great. I would also invest in a cordless, handheld vacuum with a long hose attachment to suck them up. I have literally thousands that smell up my house. I am constantly vacuuming. I have found lots of great tips on this site. I am going to try the Dawn dishwashing liquid on the outside of my house.
Best of luck to you. We live in a red brick home, and it was a absolute nightmare. We live in a small, northern alabama town, and suddenly, they came in droves. People suggesting vacuuming and turn them loose have obviously never had them covering your crown moulding, to where is one giant bug.
My husband got fed up when they started dropping in his coffee, and mounted a bug zapper in the living room. Crude, but effective. For those who are desperate, this is a effective and inexpensive option.
Lee Ellington, Missouri. I was just saying today I needed to know who is releasing these bugs. I think they do it every year around the same time! I do not believe they leave something behind that tells them where to return every year. We have a lot of ladybugs in our house. Can they be causing the chemical smell that I smell in my house? I live in South central Mississippi. In he past few years the second story to my house has became infested with the buggers starting in late fall and usually stick around until early spring.
They leave that awful smell…I have a little dustbuster and even one of those bug zappers that look like a tennis racket. But they still persist. I hung it right next to the light in my room and they were soon landing on it.
The pole is like a shiny six inch chrome rod with the bottom in a white cardboard like cup. Once they land on it, they will slowly fall down to the cup. There, they can move but the sticky stuff on their legs keeps them from falling to the floor. Though, eventually they climb up out of the bowl and fall to the floor, but will go no further. The product is only two or three dollars.
Its worked wonders for me…just letting you know. Does anyone know if state departments of agriculture are releasing these bugs? Or is it only the USDA? We really should figure out the appropriate place and contact them. This has also happened with kudzu and carp. We should not allow these people to act with impunity. Their reckless programs are hurting the environment we all have to share, and these are government agencies, and thus are accountable to the people.
We just bought a house and have these bugs everywhere. Does the Dawn dishsoap work? I love love love our house, but HATE these bugs!!! My room is completely overrun with ladybugs. Even in spring and summer they still come in. Any suggestions? I have excellent results with a sprinkling of Borax or baking soda wherever they seem to be. I have used it on window sills with great results. Ok, I had read most of your posts and you all seem to be in the US somewhere. I am in the UK and the buggars are sticking to the outside of my bungalow like glue.
They have arrived in swarms which has caused an infestation and they are vile! They are seriously worse than flies and for me to say that they really are vile!!! This morning I used my power washer with liquid sevin to spray the west side of my grey painted house.
Sure are a lot of dead Asian Lady Beatles on the ground tonight. Answer is…its not USDA shipping bugs out haha. However, u noticed fire ants are worse in last two years? Meanwhile, North America are suffering from his selfishness. They bite and stick and come into the air conditioner sleeve. Now I have them in my bathroom. They are attracted to the light. I seem to have a L. This means the owners were aware of the infestation and did not disclose that to us before purchase. I wonder if I can go after the sellers to pay for an exterminator?
They have literally ruined my life. Anytime i see a lady bug, i think back to the year I had graduated university, got married, had a baby, and moved to SE KY for my first job as a professional. All couldnt be perfect of course. Turns out the house we rented was one day suddenly infested with lady bugs. I had never heard of this happening so we were completely caught off guard.
I remember scrambling for the vaccuum, sucking up these stinky bugs, every window of the hous I took breaks times to dump the bags in a small creek next to the house before doing the whole process over AGAIN. It was so unrea l it seemed supernatral. I am not kidding, or exaggerating because they literally appeared to proliferate from the inside of the windows, never the doors.
The windows were tight as any i had ever seen. It seemed impossible for anything to sqeeze through the windows. To this day i have a hard time understanding that. The straw that broke the camels back was when my daughter popped up from crawling and stood up in front of my as i layed on the couch and a terrible smell emitted from her mouth.
Once you have an experience like this, you will not even want to see them in pictures. I just bought a used RV i have no idea were it came from but im very upset i just found dead lady bugs in the RV , we bought it from a dealer my question is even if we moved the rv will the lady bugs come back? I found about 5 or 6 adult Asian Ladybugs. In sinks and they stick to clothing. And are in my bed. Will they die if on my clothes and they go through laundry cycle. Because then would have to start all over again.
There are so many black dots all over and they fly. Some are rust colored but mainly they are black. Identified as Asian lady bugs plus grain beetles. It happens. This happens because of the variation in temperatures from the interior of the home verses the outside temperatures. The ladybugs are merely confused. Visit the Ladybug Infestation page for more details. Ladybugs are attracted to the light colored houses. Especially, homes that have a clear southwestern sun exposure.
Older homes tend to experience more problem with aggregations due to lack of adequate insulation. 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. Ladybugs don't eat fabric, plants, paper or any other household items. Aphids are very small, but very destructive pest that feed on plants. If you have rose bushes, you have probably seen aphids. 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. Occasionally, you might witness a ladybug in your bathroom getting a drink of water. Now, that's a smart lady! If you don't have a lot, just leave them. They will leave when spring arrives. 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.
