Processionary Moth Caterpillars
Beware of Processionary Moth Caterpillars
Processionary moth caterpillars pose a serious and potentially fatal threat to dogs and cats. Their urticating (barbed) hairs can cause severe reactions on contact, including redness, itchiness, inflammation, and burns to the nose, tongue, lips, and eyes. If a dog sniffs or mouths a caterpillar or its trail, symptoms can escalate rapidly to drooling, vomiting, edema, and necrosis — in some cases resulting in partial loss of the tongue. In the most severe cases, exposure can trigger anaphylactic shock, leading to choking, coma, or death.
What to do if your dog is exposed
If you suspect your dog has come into contact with processionary caterpillars, contact an emergency vet immediately — save your vet's number in your phone so you can reach them quickly when it matters. If the clinic is some distance away, rinse the affected area with water and baking soda while you make your way there. Do not allow your dog to drink from any water source that may contain urticating hairs, such as puddles or outdoor bowls near affected areas. Time is critical: the sooner your dog receives veterinary attention, the better their chances of a full recovery.
