Spring also marks the start of the processionary moth caterpillar (Spanish: procesionaria) season on the Costa Blanca. The caterpillars are particularly prevalent in areas with pine, oak or cedar trees - a fascinating sight, but one that harbours serious health risks. The fine hairs of the caterpillars can trigger dangerous allergies in humans, dogs and cats.
Why are the caterpillars so dangerous?
The fine hairs of the processionary moth contain allergenic substances that can cause severe reactions on contact with the skin or mucous membranes.
Typical symptoms are
- Itching and skin irritation
- Eye irritation
- Fever and fatigue
Contact can be life-threatening for animals, as the hairs can cause swelling in mucous membranes, leading to respiratory distress.
First aid in case of contact
If you or your pet come into contact with the caterpillars, you should take the following measures:
- Rinse affected areas with water.
- Change clothes and wash warm.
- Shower and wash hair thoroughly.
- Do not scratch or rub to avoid spreading the allergens.
- In case of severe symptoms: Consult a doctor or vet immediately.
Where are the caterpillars active?
The caterpillars prefer to build their prey-like nests in pine crowns and set off from there. The season lasts until the end of April, which is why particular caution is required during this time. Keep a low profile in affected areas and avoid contact with nests or caterpillars.
Tips for prevention
- Keep your distanceDo not touch nests and caterpillars.
- Note wind: The hair can be dispersed by the wind.
- Protect petsKeep dogs on a lead when walking and stay alert.
Better safe than sorry
The processionary moth caterpillar may only be a small danger, but its impact is great. With simple precautions, you can protect yourself and your pets from the health risks. Stay vigilant and enjoy spring without any allergic surprises.
