Orihuela Launches New Plan to Tackle Pine Processionary Caterpillar Across the Municipality

A Proactive Approach Across the Whole Municipality

Orihuela has launched a formal new pest control programme targeting the pine processionary caterpillar across the full extent of the municipality — covering both Orihuela Costa and inland areas. The programme has a budget of just under €30,000 and a tender deadline of May 14.

Councillor Noelia Grao said the aim is to "strengthen the protection of green spaces while acting in advance of outbreaks rather than reacting once the pest has already spread." The plan is designed for early, coordinated intervention — targeting high-risk zones before peak caterpillar activity, rather than responding after infestations have already taken hold.

Why the Processionary Caterpillar Is a Serious Concern

The pine processionary caterpillar is not just an environmental nuisance — it is a genuine public health risk. The caterpillars carry highly irritating hairs that can cause serious reactions on contact:

• Children in parks can develop rashes, eye irritation, or respiratory reactions, particularly in sensitive cases
• Dogs are at particular risk — exposure can lead to severe inflammation, serious allergic reactions, and in some cases emergency veterinary treatment
• Adults can also experience significant skin irritation simply from walking near affected trees

The caterpillars typically appear from late winter through spring, forming the distinctive nose-to-tail "processions" as they descend from pine trees to the ground — a pattern that makes them easy to identify but difficult to avoid in affected areas.

Where the Programme Will Focus

The programme covers public parks, pine forests, and green spaces across Orihuela, with particular attention to residential urbanisations along the coast and inland. These areas have significant pine tree presence and high footfall from residents and visitors during spring months.

Dog owners and parents of young children in affected areas are advised to remain vigilant around pine trees during the spring season, avoid letting dogs sniff or approach caterpillar processions on the ground, and seek medical or veterinary attention promptly if contact is suspected.
