Imagine opening a window on a warm, sunny day to let in some fresh air. Moments later, you freeze, as dozens, or even hundreds, of small insects start pouring out of the window frame. Sounds like a scene from a horror movie? Unfortunately, it's a reality for many of us, and the main stars of this unsettling scene are Asian lady beetles. Forester Dariusz Dziektarz captured a similar situation in a video he posted online, while also explaining this unusual phenomenon.
Are Asian lady beetles dangerous? They are becoming a real plague in Poland.
Although Asian lady beetles don’t pose a direct threat to human life, they can be extremely bothersome. A swarm of small insects trying to enter through your window frame is likely to cause concern for most of us. This is exactly what happens when Asian lady beetles attack, as they swarm into our homes, searching for a warm shelter for the winter. But this story has an even more interesting twist. As forester Dariusz Dziektarz explains in the video shared on X, these beetles are facing an unusual problem: the fungus Hesperomyces harmoniae, which is transmitted sexually.
The fungus grows on the beetles' bodies, draining their bodily fluids and weakening them. It's a venereal disease that Asian lady beetles catch in large groups, such as when they overwinter in our homes. Furthermore, the forester reveals that these insects can even drink vertebrate blood, adding an extra level of eeriness to them. Dariusz Dziektarz is the author of a book titled "Rozejrzyj się! Fascynujący świat polskiej przyrody" ("Look Around! The Fascinating World of Polish Nature"), in which he describes Asian lady beetles and the issues associated with them.
What repels Asian lady beetles? Try these effective methods.
Although Asian lady beetles may seem harmless at first glance, they can become a real nuisance. They can bite humans, causing mild skin irritation. Additionally, they emit an unpleasant odor and leave hard-to-remove stains. Their presence can be extremely annoying, but luckily, there are several natural and effective ways to get rid of them. So, what repels these insects?
- Spirit vinegar: Lady beetles can't stand this smell. To protect your windows, simply dilute vinegar 1:1 with water and spray it on the window frames. Don’t forget the door frames as well, including balcony doors.
- Lemon juice: They dislike this just as much as vinegar. You can spray potential entry points with lemon juice or diluted citrus essential oils, both of which effectively repel them.
- Peppermint: Growing peppermint plants near windows and doors can help deter lady beetles from entering.
