Sclerodermus domesticus infestation

AIM: Sclerodermus domesticus is an insect belonging to the order Hymenoptera. Female of S. domesticus feeds on larvae of xylophagous Coleoptera and Lepidoptera living in the galleries they dig in old wooden furniture. Human infestation is rare. METHODS: In the last few months, we observed nine adult patients (7 males and 2 females) who were affected by S. domesticus infestation. Seven patients were antiquarians or restorers and two were housewives. The rash was characterized by erythematous-papular lesions, accompanied by pruritus and/or pain. In addition, 7 patients reported general malaise and fever. In all cases it was possible to find specimens of S. domesticus in furniture or house dust. RESULTS: Complete remission was obtained with topical corticosteroids, oral anti-histamines and pest control of furniture. CONCLUSION: Antiquarians and restorers and, in general, the people in close contact with furniture infested by S. domesticus may be stung by these insects. S. domesticus infestation can therefore be considered as an occupational disease in these subjects.
