One of Italy’s Most Dangerous Insects: Do Not Approach or Touch

Beware of Pine Processionary Caterpillars: Risks and Safety Measures

As spring approaches, there is a danger that often goes unnoticed: pine processionary caterpillars.
These insects, seemingly harmless, are actually one of the most dangerous in Italy.
They can be extremely harmful to both human health and domestic animals.

The Danger of Pine Processionary Caterpillars

Pine processionary caterpillars are moths of the Thaumetopoeidae family.
When disturbed, their caterpillars release a toxin called thaumetopoein.
This substance can cause a severe form of hives in humans, characterized by intense skin rashes, itching, and redness.

If the toxin comes into contact with the eyes or respiratory tract, it can cause additional health problems such as eye irritation, nasal congestion, and breathing difficulties.
It is important to be aware of this risk and take appropriate measures to avoid contact with pine processionary caterpillars during outdoor activities.

Risks for Humans and Animals

Pine processionary caterpillars are dangerous mainly due to their irritating hairs, which release a toxin that can cause severe and potentially fatal allergic reactions in domestic animals and children.

Direct contact with the caterpillars or their nests without protection can lead to severe skin rashes and respiratory problems.
Moreover, the toxin can be airborne, posing an additional health risk.
It is crucial to be aware of the dangers these insects pose to animals, such as dogs, who are particularly vulnerable to the risks associated with their hairs and toxins.

Immediate Actions and Preventive Measures

If stung by a pine processionary caterpillar or exposed to its toxin, a severe allergic reaction is likely.
Symptoms include skin rashes, intense itching, redness, and swelling.
In some cases, contact with the toxin can also cause respiratory problems, eye irritation, and mucous membrane irritation.

It is essential to immediately wash the affected area with cold water or alcohol and seek medical assistance if symptoms persist or worsen.
Additionally, avoid scratching or rubbing the affected area, as it could further spread the toxin and exacerbate the symptoms.

Pine processionary caterpillars feed mainly on conifers and are commonly found in forests, parks, and gardens.
Their nests can be found on tree branches, especially in spring when the insects are most active.

To avoid contact, it is important to check areas where pine processionary caterpillars are suspected to be present and be cautious when outdoors, especially during warmer months and when walking with pets and children.
Consult local authorities or experts for updated information on the presence of pine processionary caterpillars in your area and take necessary precautions to protect yourself and your pets.
