Processionary Moths in Mallorca: How Dangerous Are the Caterpillars for People and Dogs?

Answer

Are processionary caterpillars in Mallorca still a risk after the nests fall from the trees?

Yes. Even when nests are knocked down, the stinging hairs can remain in branches, cones, or soil and can still be stirred into the air. That means discarded nests and treated areas can stay irritating for some time, especially for children and dogs.
