More precisely, it is an insect of which there are different species; among these, the best known is probably the Thaumetopoea pityocampa, commonly known as "pine processionary" or "pine caterpillar".
The larval stage of processionaries is arousing interest and concern, not only for the ecological damage that the larvae are able to cause, but also and above all for the danger they represent for humans, dogs, cats and other animals, wild and otherwise.
The processionary dermatitis occurs suddenly with a greater incidence in the months of May and July, or in the period in which the larvae come out of the nest.

These hairs, in fact, easily detach from the insect and can be carried by the wind, therefore, they can also be suspended in the air, especially in places infested by these organisms.
.The stinging hairs thus deposited in the skin can then penetrate it leading to the onset of processionary dermatitis. The latter is characterized by the appearance of raised reddened papules, generally very itchy, but which can also cause pain. The distribution of papules on the skin is usually uneven and asymmetrical.
The act of scratching, which is spontaneous immediately after contact with the stinging hairs of the insect, can further facilitate their penetration into the skin, making the situation even worse.
Allergic reactions
In sensitive individuals, following contact with the stinging hairs of the processionary moth, it is possible to develop an allergic reaction which can also manifest itself with systemic symptoms, sometimes very serious. Clearly, in such a situation, it is necessary to call the medical assistance immediately.
However, the onset of severe allergies appears to be fortunately a rare occurrence.
, as they could aggravate the situation and delay healing. based on corticosteroids are not recommended unless specifically prescribed by your doctor or dermatologist. In this regard, however, we specify that the usefulness of corticosteroid drugs in the treatment of processionary dermatitis is the subject of conflicting opinions among doctors.
In some cases, moreover, the doctor or specialist may deem it necessary to resort to the administration of antihistamine drugs, the use of which, however, is usually indicated in the presence of allergic reactions.
We conclude by specifying that, although astringent gels and some pharmacological ointments can be freely purchased without the obligation to present a medical prescription, in case of processionary dermatitis it is still advisable to consult a doctor before using any product.
or go hiking.In the unfortunate event that you come across the processionaries, it is very important do not crush them and do not try to eliminate them with do-it-yourself methods of dubious use. The stinging hairs, in fact, can remain attached to clothes, objects and even to the soles of shoes. In the event of a close encounter, therefore, the most appropriate behavior is to notify the competent authorities (for example, traffic police, police, municipal authorities, etc.) and move away from the place in question.
It is advisable to leave clothes and shoes that may have come into contact with the stinging hair of the larvae outside the home, washing them thoroughly. Some suggest using adhesive brushes to remove any hairs and only then proceed with washing clothes and footwear, preferably using a pair of gloves to carry out the operations described above. This caution should be even more respected if there are children or animals in the house, such as dogs or cats, but not only. The stinging hairs, in fact, are extremely dangerous even for our four-legged friends who, inhaling or ingesting them, can meet very serious consequences.
