The State Forests are warning about the coming invasion. “This is a good example of huge problems”

The Asian ladybug, otherwise known as the harlequin, is yellow or orange with black dots and is a real nuisance every year. The invasion of these insects usually begins in autumn, but the State Forests warn that soon we will start seeing Asian ladybugs more and more often.

Asian ladybugs were brought to Europe in 1964 to Ukraine. Their job was to eat the aphids and reduce the presence of this pest, but no one thought that she herself would become a big problem. It naturally occurs in Asia and is a beetle from the ladybug family.

Are Asian Ladybugs Dangerous? Their bite can cause allergies

We see swarms of orange ladybugs in the fall, when they occupy house entrances, walls and windows in search of crevices where they could hide for the winter. Asian ladybugs are an invasive species, and although they resemble the popular elliptical ladybug in appearance, they differ in color and number of dots. Harlequin ladybugs are pests. It also happens that they bite people, and their bite can cause a strong allergic reaction and cause symptoms such as: rhinitis, swelling, asthma, or angioedema.

State Forests warn. “Adult ladybugs will knock on our homes in the fall”

As the State Forests warn, the period of development of ladybugs is just beginning, and on the walls or walls we can see pupae stuck to them. These are Asian ladybugs that will soon grow up and try to enter our homes.

Slowly, you can feel the foretaste of the autumn invasion… Asian ladybugs are eating aphids for now and are going through the next stages of development, but soon we will see pupae stuck to the walls, and adult ladybugs will knock on our homes in the fall. (…) This is a good example of the huge problems that invasive alien species cause. In just a dozen or so years, it has taken over virtually all of Poland, maintaining a huge population, which we have been experiencing every autumn for several years.

To prevent ladybugs from entering the apartment, it is worth installing a mosquito net on the window. We can win the fight against ladybirds by using the ones whose smell they hate. Harlequins do not like the smell of orange oil, camphor or menthol, so in order for them not to gather near our windows or doors, it is worth these places. An unpleasant smell for them will effectively scare them away and make them avoid our apartment with a wide berth.
