Asian Lady Beetle: Be Careful, As It Can Be Dangerous For The Human Health
As it seems, it’s a season of the Asian lady beetle, also known as Harlequin ladybird. These bugs appear in a period that’s not typical for insects, mostly at the end of October and during November. But sometimes, we can even see them up until March. During this time, they’re seeking for their winter host. Even though they usually wander, they can often end up in a residential area and in a house, where they cause trouble for the residents.
Asian Lady Beetle
Do you know how to identify an Asian lady beetle? This is a multicolored oval beetle, a quarter inch long, ranging from yellow, to orange and red color. They usually have black spots on their wings, but, they don’t have to have them at all. They appear in large numbers, with frequent visits to rural and urban areas. Usually, they attempt to enter the interior of our houses, remaining close to the windows.
These are not damaging beetles, as they do not make holes in furniture, carpets or walls. Also, they don’t lay eggs indoors. They are attracted to light colors, such as yellow, white and light gray. In addition, they may be attracted by lighting and warmer temperatures.
But, did you know that the Asian lady beetle can be dangerous for people, especially curious children? Of course, the question would be: how to eliminate these insects from our homes? If you try to kill them with your hands, or by hitting them with an object, know that they leave a yellow defensive secretion on the surface, which can be very smelly. Sometimes, these stains cannot be removed for years!
Are Asian Lady Beetles Dangerous For The Human Health?
These ladybugs do not pose a threat of transmitting diseases, such as the case with mosquitoes or ticks. However, they are considered to be a very strong allergen. Thus, they can cause various allergic reactions in people, such as skin rashes, conjunctivitis, extremely strong coughs and even asthma. Knowing this, people should be very careful when they come in contact with this bug. No wonder that children fall in the most vulnerable category.
How To Protect Your Home
If you have problems with the Asian lady beetle, the easiest way is to use a vacuum cleaner and simply vacuum them. Then, it’s recommendable to burn them. It’s not advisable to release them in nature, as there’s always the risk of returning.
Also, you should seal the openings and cracks of your home, preventing these ladybugs, and other insects, from entering. Find all potential entrances, such as cracks around the doors, windows, wires, boards and so on, and close them. The best time to do this is in early spring and late summer, before the insects try entering our homes.
It’s not recommendable to use insecticides for ladybugs, as they can leave unwanted yellow secretions of the walls and other surfaces.
