Getting rid of ladybugs once they have invaded a home can be a challenge, but it is one that most people can accomplish with persistence. The key is to take a multi-pronged approach that focuses on blocking the means of entrance for ladybugs, providing them with an alternative place to hibernate, as well as using traps and pesticides. The best method for getting rid of ladybugs depends on the extent of the infestation as well as the circumstances of the family living in the infested house.
While many people find ladybugs, also known as ladybirds, attractive and an asset in controlling garden-destroying aphids, they also don't want them in their homes. Ladybugs secrete a pheromone that attracts other ladybugs, which can cause swarms to form. Once this happens, homes can be at risk as ladybugs seeking shelter invade. Some ladybugs bite, and they can secrete foul-smelling discharges that can result in permanent staining of walls and other surfaces.
Ladybugs tend to enter homes through open windows as well as gaps in window frames and walls. Poorly insulated homes can be particular targets of the ladybug, as they are easier to enter. The first step in getting rid of ladybugs is to determine where they are entering the home and sealing these entrances. Next, it is a good idea to find additional areas where a ladybug could drop in unannounced and seal those areas up too. Gardeners who would like to keep a population of ladybugs nearby may want to purchase a ladybug habitat for their garden. These little homes provide a safe but separate space for ladybugs to hibernate.
Once ladybugs invade a home, the homeowner must decide if he wishes to eliminate them or just wait until the seasons change and the ladybugs leave of their own accord. Options for extermination include the use of diatomaceous earth, a natural, non-toxic powder that can be sprinkled around the house. When ladybugs and other insects encounter diatomaceous earth, the substance creates tears in their exoskeleton, resulting in death by dehydration. Another option is to use a canister vacuum with a hose attachment to scoop up ladybugs for disposal.
If sealing up the home or using natural removal options don't work, the use of a pesticide may be necessary. Homeowners who are uncomfortable using a pesticide on their own should contact a pest control expert about getting rid of ladybugs. While a professional extermination can be costly and involves the use of poisonous chemicals, it may be the most effective and least expensive way of getting rid of ladybugs in the long term.
