Hairs (setae) from the Oak Processionary Moth (OPM) can result in a range of reactions if they penetrate skin, mucous membranes or other sites. A number of steps can be taken to minimize contact with these hairs.
Scientific name: Thaumetopoea processionea
Facts:
(1) The setae can cause reactions for several years after release.
(2) Setae can be carried by the wind.
(3) Risk is present during the late Spring and Summer as the caterpillars are active.
(4) Animals may also be contaminated by setae.
Goals:
(1) Remove any setae on body surfaces.
(2) Prevent introduction of setae into the home.
Precautions:
(1) Avoid handling the caterpillar and nest.
(2) Wear gloves when removing setae.
(3) The hairs can be removed by using adhesive tape, by washing or by vacuum.
(4) Shoes should be cleaned outside.
(5) Clothes should be immediately removed and washed in hot water.
(6) Take a shower and wash the hair.
(7) If the eyes are involved rinse the eyes with water and contact an ophthalmologist.
(8) Attend to exposed animals outside.
Therapeutics:
(1) skin lesions: antihistamine, topical corticosteroid
(2) respiratory symptoms: bronchodilator
(3) severe systemic reaction: parenteral corticosteroids
(4) eye involvement: may include antiseptic; follow-up for 6 months if corneal penetration
(5) anaphylaxis: epinephrine; parenteral steroids and antihistamines
