Red alert: Oak processionary moth threatens health in Saxony!

With a critical look at current nature, which continually presents us with new challenges, the oak processionary moth is making a name for itself. This pest has currently established itself in Saxony and is causing a stir in various federal states. World reports that the caterpillars of the oak processionary moth pose health risks in the form of caterpillar dermatitis. Of course, this is a headache because these allergic reactions can be not only unpleasant but also seriously debilitating.

A major problem in the distribution of this butterfly is the stinging hairs that develop from the third larval instar. These contain the nettle poison thaumetopoein, which can be extremely unpleasant for people. It ranges from itching to swelling to breathing problems and eye irritation. In the warmth and dryness of recent years, the oak processionary moth has found optimal conditions and is rapidly spreading throughout Germany - from Baden-Württemberg through Lower Saxony to Mecklenburg-Western Pomerania. The infestation situation can vary greatly from region to region, but one thing remains constant: the health effects of the stinging hairs are more acute than the damage caused to the oak trees themselves.

Health risks and control measures

But what exactly is behind this health threat? Loud Mirror The symptoms of contamination are extremely unpleasant: from skin redness, nasty itching to respiratory irritation. Rarely, fever and circulatory reactions even occur. This means that measures are being taken to combat the oak processionary moth in many regions of Germany - because protecting people is the priority here.

The Federal Environment Agency emphasizes that the use of insecticides should be avoided if possible in regions with weak infestations. Instead, alternative measures such as vacuuming the caterpillars or nests can help. An environmentally friendly solution is the use of nematodes, which are already being used successfully in Lüneburg. These are considered natural and can control up to 90% of the oak processionary moth population without harming people or the environment.

The future of pests in Germany

The mass reproduction of the oak processionary moth can be observed particularly in the northeast and southwest of Germany. However, there are also signs of declining populations in many areas. This could potentially be a ray of hope, as climate change not only contributes to the spread of the insect pest, but also has an impact on the life cycle of the oak trees themselves.

Is this the end of the oaks now? No, the trees can definitely sprout again after they have been damaged. However, repeated infestations can cause serious damage and weaken the trees in the long term. Experts generally recommend preventive measures, putting up warning signs and cordoning off affected forest areas. However, combating them in nature reserves remains a delicate matter that is subject to strict requirements.

So all we can do is closely monitor the development of the caterpillars and implement the necessary measures to contain the oak processionary moth. Because nature remains unpredictable, and there is certainly something to be done to protect our forests and, above all, people's health.
