Attention: Stinging hairs from the oak processionary moth are a health hazard!

There is currently reason for caution in the region around Cologne: the Rems-Murr district office is warning about oak processionary moth caterpillars. Not only are these little pests unpleasant to look at, they can also cause severe allergic reactions. Increased caution is required, especially at the edges of forests and in sunny locations, as the caterpillars' stinging hairs can have dangerous effects on people.

But what exactly makes the oak processionary moth so problematic? It is a grey-brown moth whose caterpillars feed on oak leaves. These caterpillars develop special, hollow stinging hairs that break off easily and contain toxic substances. The hair can be carried over long distances by air currents, so those of us with allergies need to be careful even if they don't come into direct contact with the caterpillars.

Health risks in detail

The symptoms caused by touching the stinging hairs range from skin redness to allergic shock. Contact can lead to caterpillar dermatitis, conjunctivitis, respiratory irritation and other health complications. Groups particularly at risk are those seeking relaxation, residents, children and forest workers. It is therefore recommended to protect sensitive skin areas such as the neck and forearms well and to freshen up immediately in the event of contact: change clothes, shower and wash your hair thoroughly.

Particular caution should be exercised in the affected areas, particularly in sparse oak forests and in settlements in warm, dry regions. The Federal Environment Agency adds that proper defense against these caterpillars includes not only avoiding contact, but also informing local health and forestry departments. In the event of an infestation, special measures are recommended, including posting warning signs and closing off affected areas.

Preventive steps and control strategies

Since the spread of the oak processionary moth is favored by climate change, destroying oak stands near playgrounds or barbecue areas is particularly important during the peak season in July and August. Experts advise avoiding such places to minimize health risks. Control methods are usually only possible for professional users who are allowed to vacuum or scrape off the web nests. Chemical control is usually only recommended for severe infestations.

The caterpillars go through several stages of development and develop dangerous stinging hairs at an early stage. These hairs remain active for years and can be stirred up again, further complicating the situation. It is therefore essential for anyone who spends time outdoors or lives near oak trees to be vigilant and constantly informed about current occurrences.

The oak processionary moth is not just a regional challenge, but an example of the larger ecological changes caused by climate change. So stay careful, stay informed and protect yourself and your loved ones from possible dangers!
