Houseflies, similar to all insect pests, locate their hosts, humans and animals, by way of the hosts' odors and the flies' visual stimuli. After locating their hosts, houseflies and other insects make contact and then operate by taste, thermal and tactile stimuli. That is, if they like the human's taste, warmth or feel, they will just hang around and annoy them. Insects have somewhat different tastes than humans do... Sensitivity to stimuli may be optimal if people are dirty, sweaty, or just simply warmer than usual.
