The spread of processionary moth caterpillars across Western Europe has increased the incidence of reactions to their urticating hairs. They are found in South East England, continental Europe, North Africa and the Middle East.

The shed hairs can persist in the environment for years, and if licked or ingested, can cause intense swelling of the tongue and oral tissues, which can lead to severe tissue damage and necrosis.

Tyrophagus putrescentiae is one of many forage mites increasingly recognised as potent allergens in stored food products and homes. Allergens produced by this non-parasitic mite can cause atopic dermatitis.

The duration of each life cycle stage and the fecundity of female mites are highly dependent on temperature and relative humidity, so populations may be on the increase as we move into spring (in the northern hemisphere).

Learn more about forage mites by reading the parasitology article on .
