Year on year, the number of geographical areas affected by pine processionary moths increases dramatically. The main risk to humans and pets comes from their poisonous hairs: doctors and allergy specialists warn against contact with the larvae, which can cause rashes, conjunctivitis and asthma-like symptoms, including life-threatening allergic shocks. Rentokil has uses specialised spraying equipment which can reach up to 30 metres to treat against these pests.
