Answer

When are processionary moth caterpillars usually a problem in Mallorca?

They are commonly seen from mid-February, when the hairy nests begin appearing in pine forests, parks, and some suburban gardens. The exact timing can vary from place to place, so walkers and dog owners should stay alert in late winter and early spring. Warning signs and local updates are useful because the nests may still pose a risk after they fall.
