The present invention provides an apparatus and method for attracting mosquitoes by using the microbe product as the mosquito bait as well as simulating the human emanated odors. A bait-releasing unit/means is included to enhance the release of the mosquito bait. A well-controlled heating assembly can be used to generate a suitable thermal gradient for simulating body temperature and evaporating the bait.
