Ladybugs pose a nuisance both inside and outside some homes in the United States. One breed, the Asian ladybug, is particularly troublesome because it does not die during the winter cold. By following a few proven methods, you can rid your home of the bugs.
It might sound ridiculous to some people, but some pest control experts suggest simply capturing the bugs and sending them outside. To do this, you can wrap duct tape with the sticky side up around your hand and tap your hand on the ladybugs. Then take them outside, remove the tape and discard it into a trash can.
Many people suggest using a vacuum to remove the beetles from your home. If you choose this method, be sure to dump the bag outside. Otherwise, the ladybugs will reemerge into your home. Another option is to design a filter for the vacuum cleaner from a stocking. You also can use a wad of paper towels.
For ladybugs that are on the outside of your home, spray with a hose. You might need to spray more than once per day. Doing so knocks ladybugs off your exterior walls, but it does not kill them or even discourage them from returning to the same spot.
While removing ladybugs helps, it does not attack the bigger problem, which is treating the home to ensure no further infestation. Many chemicals are used to treat ladybug infestations. The most natural product to use is Borax, which repels and kills many insects when it is poured around baseboards and in other areas where insects penetrate homes and move through them. Borax is considered poisonous and therefore, you should try a more natural product first.
An effective and natural product for eliminating ladybugs from your home is diatomaceous earth, which is available at gardening centers and many hardware stores. The powdery substance is composed of microscopic shells with sharp edges. The sharp edges of the shells lacerate insects, including ladybugs. The cuts kill the ladybugs. According to some homeowners, diatomaceous earth works as well as any pesticide-free approach.
To prevent future ladybug infestations, use foam sealant and other products to close up cracks and crevices where ladybugs enter. The most important areas to watch are parts of structures that receive lots of afternoon sun. Studies show that Asian ladybugs are attracted to illuminated surfaces, including those lit by afternoon sun, which tends to appear on the southwest corner of structures in the United States. Ladybugs also flock most to areas of light and dark contrast. Such areas include those spots around windows edged with lighter trim the rest of the building.
