Page 30 Processionary Caterpillars


The processionary caterpillars are unusually early this year and are a serious risk to our dogs.


The most common pine processionary caterpillar in Spain is the ‘Thaumatopea pytocampa’. In the summer, in its moth form, each moth lays about 300 eggs in the branches of the pine- trees. When the caterpillars hatch they make a silk nest designed to keep them warm during the impending winter. These are the typical cottony whitebags which are seen at the top of the pines. When the temperatures rise above 15ºC, the caterpillars migrate in a procession. Their destination is an ideal place to burrow and form pupae, which will re-appear in the summer as moths.


Why are the caterpillars such a danger to our dogs? The caterpillars have specialised dart-shaped hairs that release a toxin called taumatopenia. This toxin is a protein that produces hyperacute inflammatory reactions similar to those produced in acute allergic reactions, giving rise to toxic-irritative dermatitis. Poisoning can occur through direct contact with the caterpillars and their secretion or by contact with their stinging hairs that can be carried by the wind. Also fallen nests are a real danger since some hairs and larval excretions are likely to remain inside; even nests from previous years are a danger. If our dogs nuzzle or play with the nests these hairs are very likely to come into contact with their skin and mucous membrane.


How will we know if our dog has been affected? The classic symptoms in oral contact are a show of anxiety, rapid swallowing acts, touching the mouth with their feet and/ or hypersalivation. Within minutes the animal may develop an inflammation of the mouth and tongue so intense that it may be unable to fully close its mouth, and if the caterpillar has been eaten then the animal will likely be vomiting and/or having a massive swelling of the larynx.

What do I do if my dog comes into contact with the caterpillars? If you see your dog touching one of these caterpillars, or it shows any symptoms that suggest it has done, you are already in an emergency situation. Acting fast will make a big difference towards successful recovery. Immediately wash the tongue or the affected area with hot water as the heat deactivates the toxin. Other alternatives are vinegar or soap. Never rub the injured part, as this will break the hair(s) further, resulting in more of the toxin being
