If you want to get rid of ladybugs that are getting inside your home, you should try to determine how they are getting in and seal those areas off. You can also use pyrethin-based insecticides or diatomaceous earth to kill ladybugs indoors and outdoors. Pyrethin insecticides are typically safe to use in your home once they dry, and diatomaceous earth is also safe to use because it is an all-natural powder made from fossilized algae. In addition to these methods, you could also use your vacuum cleaner to get rid of ladybugs. Sucking ladybugs up with your vacuum cleaner and emptying the bag far away from your home should help eliminate many bugs at once.
No matter what methods you use to get rid of ladybugs, they will probably keep coming back if they can still find a way to get into your home. Ladybugs often get inside through cracks around window screens, doors, and occasionally cracks or crevices in siding. You should inspect your home carefully for ladybug entryways and seal those areas up with weatherstripping, which is a clear, adhesive tape, to keep them from being able to get inside. Weatherstripping is generally a good temporary fix for ladybug prevention, but if you have ill-fitting screens or cracks in your windows and doors, you may ultimately have to get those repaired to keep ladybugs at bay for good.
Insecticides containing pyrethins, which are made up of several chemicals that occur naturally, should help to control your ladybug population. Pyrethins are thought to be safe when used inside, but you should probably take precautions when using it regardless. Try to avoid skin and eye contact when using pyrethins. You can also use pyrethin-based insecticides outside of your home if you have a problem with ladybugs outdoors. If you are thinking about using insecticide to keep ladybugs out of your garden, keep in mind that ladybugs can be beneficial in the garden because they eat aphids, which tend to be very problematic pests.
Diatomaceous earth is another method that may be used both indoors or outdoors to get rid of ladybugs. Most types of diatomaceous earth come in powder form, and the powder granules are actually very sharp. When the exoskeleton of a ladybug comes in contact with any of the diatomaceous earth granules, the granules usually cut the exoskeleton, thereby killing the ladybug. The powder is not typically harmful to humans, and you can sprinkle the powder around the areas of your home where ladybugs are most prevalent and vacuum up the powder along with all the dead ladybugs a few days later. You can also use diatomaceous earth outside in your garden to kill both ladybugs and many other types of insects.
If you want to get rid of a lot of lady bugs quickly, you may be able to do so by using your vacuum cleaner. Ladybugs are easy to vacuum up, particularly if you have a vacuum cleaner with a hose attachment. You can use the house to suck up ladybugs that you find crawling on your ceiling and around your windows as well as those you find in the floor. After you have vacuumed up all the ladybugs you see, you can take the vacuum bag outside and dump them all out. The vacuum cleaner method probably won't get rid of all your ladybugs overnight, but it should make a dent in their population.
