Pest Education: Lady Bugs in Ontario

Monday, December 26, 2022 by Greeny’s Pest Control Inc.

Ladybugs, also known as ladybirds or lady beetles, are a type of beetle that are commonly found in gardens and fields in Ontario. These insects are often seen as a beneficial presence in the garden, as they are known to feed on a variety of pests such as aphids, mites, and scale insects. However, in some cases, ladybugs can become pests themselves, particularly when they invade homes in large numbers.


One of the main reasons why ladybugs may become a pest in Ontario is due to their habit of seeking out warm, protected places to overwinter. As the weather starts to cool in the fall, ladybugs will begin to search for shelter to ride out the winter months. This can lead them to congregate in large numbers on the exterior of homes, particularly on the south and west facing walls. While the sight of thousands of ladybugs crawling up the side of a house may be alarming, they are generally harmless and do not cause any damage to the structure of the home.


However, once inside, ladybugs can become a nuisance due to their tendency to crawl on walls and ceilings, as well as their pungent odour when crushed. They may also leave a yellowish stain on surfaces when they secrete a fluid from their leg joints as a defence mechanism. In addition, if left unchecked, ladybugs can reproduce and lay eggs inside the home, leading to even more of a pest problem.


To prevent ladybugs from becoming a problem in your home, it is important to seal any cracks or gaps in the exterior of the house, particularly around windows and doors. This will help to keep ladybugs out while also reducing the overall number of pests that may enter your home. If you do find ladybugs inside your home, the best course of action is to carefully remove them and release them back outside. Avoid using insecticides, as this can be harmful to both the ladybugs and any beneficial insects in your garden.


If you are experiencing a large infestation of ladybugs in your home, it may be necessary to seek the assistance of a professional pest control service. These experts have the knowledge and experience to safely and effectively remove ladybugs from your home and help prevent future infestations.


In conclusion, while ladybugs are generally considered beneficial insects in the garden, they can become pests when they invade homes in large numbers. To prevent ladybugs from becoming a problem in your home, it is important to seal any cracks or gaps in the exterior of the house and to seek the assistance of a professional pest control service if necessary. By taking these simple precautions, you can enjoy the benefits of ladybugs in your garden while avoiding any potential pest issues.
