Lace bugs sometimes fall out of trees, land on people, and bite, which, although painful, is a minor nuisance. No medical treatment is necessary. There are reports in Europe, e.g., Italy, France and Romania, of ''Corythucha ciliata'' biting humans and some people have painful reactions, e.g., dermatosis.
