Bed bugs
(Hemiptera)
During
the day, bed bugs hide in crevices in walls and furniture; at night they can
travel considerable distances to reach a sleeping person. Burning wheals,
turning into firm papules, occur in groups wherever the crawling bugs have easy
access to the skin, the face, neck and hands being the most common sites.
Treatment should be based on the application of insecticides to walls and
furniture likely to be har-bouring the bugs.
Myiasis
The
larvae of several species of fly develop only if deposited in living flesh;
humans are one of several possible hosts. The skin lesions look like boils, but
movement may be detected within them. The diagnosis is proved by incising the
nodule and extracting the larva.
