Pine Processionary: What Is It and Why Is It Dangerous for Pets?
With rising temperatures—especially in spring and autumn—the pine processionary caterpillar becomes increasingly common in pine forests and even private gardens. But what is it, and how can it affect our pets?
The pine processionary is a caterpillar species whose larvae, starting from the third stage of development, carry clusters of tiny, orange, stinging hairs on their backs. These hairs are released into the air when the caterpillars are disturbed or move in groups, creating a dangerous situation for both humans and animals.
If these microscopic hairs come into contact with skin or mucous membranes, they can cause serious allergic or inflammatory reactions.
Why is it dangerous for dogs and cats?
Dogs, in particular, may sniff, lick, or even ingest these caterpillars while walking outdoors. Contact or ingestion can lead to:
-
Intense swelling of the tongue and oral mucosa
-
Ulcers, necrosis, and even tissue loss
-
Severe pain, drooling, and difficulty eating or breathing
Quick action is essential.
The severity of the injury depends on how long the caterpillar or its hairs remain in contact with your pet’s tissues. If you suspect your pet has come into contact with a processionary caterpillar, seek veterinary care immediately.
