What is the pine processionary and its characteristics
Before going into details about home remedies for the pine processionary, we want to talk more about it so that you know it well. These are the main characteristics of the pine processionary :
- The processionary is actually a nocturnal butterfly , which in its adult phase does not represent any danger to humans or other animals. However, this insect is much better known for its caterpillar phase which, in addition to attacking plants, has stinging hairs and is dangerous to us and other animals, such as dogs and cats.
- The processionary gets its name from the fact that, when the caterpillars descend from the pine tree, they tend to form a characteristic procession as if it were a single caterpillar of extraordinary length, which advances making shallow sways.
- It is used to infest pines in central and southern Europe, as well as in North Africa and the Middle East. Its favorite tree is the black pine, but other types of pine and even cedars and firs are not safe from this pest.
- It appears when temperatures rise and there is less rain, when the adults lay their eggs. A month later the caterpillars hatch from the eggs, and in another month they already have their stinging hairs.

- The urticarial reaction caused by the hairs can range from mild to very serious, and may be a medical emergency, depending on the amount of these and if the affected person or animal has an allergy or not. Due to this, it is necessary to act against this plague as soon as possible and go directly to the doctor or veterinarian in case of suffering its attack, which for them is, simply, to defend themselves against someone who gets too close.
