Pine Processionary! Quick help is important now, otherwise this encounter can end very sadly and your holiday would be completely ruined. That’s why it’s important to be careful right from the start. Better safe than sorry!

What are pine processionary?

They have nothing to do with spiders as one could imagine from the big nests they are spinning. Pine processionaries belong to the butterflies family and are moths. However, it takes some time until a moth develops. First of all the eggs are laid in the crowns of a pine tree by the females. In autumn the young caterpillar develops, which hibernates in the egg. As soon as it gets warmer and spring comes, the caterpillars hatched. In Spain this can happen already in January depending on the temperature. They skin shed up to six times before the pupation occurs. The caterpillars create a kind of large spider’s nest, in which they retreat during the day. They are sociable and go at night together in small groups in a procession in search of food. Hence the name “Processionary”.

Why are they dangerous for humans and dogs?

With the third moulting of the caterpillars the poisonous and for us humans dangerous hairs develop. These contain a nettle poison and can cause severe skin irritation up to asthma attacks. Children are particularly at risk because they are smaller and, of course, curious. It is advisable to take children in such an area by the hand and point out to them that the nests and caterpillars can become very dangerous.

The situation is different with dogs who usually run with their noses on the ground and are constantly sniffing. For dogs, contact with procession weirdoes can even be more fatal. Because the fine hairs can enter the respiratory tract and cause it to swell within seconds, so that the animal cannot breathe anymore and suffocates. There helps only one thing, take the dog to the short leash and watch where his nose moves. If you, your child or the dog has come into contact with a caterpillar or nest, you should see a doctor in no time. Every minute counts for the child and dog! The simplest thing is not to come into contact with the caterpillars at all and to to circumvent nests widely and keep an eye on the ground.

You should also be careful when walking through the woods. As soon as one of the nests appears, then you can assume that it is not the only one.
