The invention discloses a mosquito catching device comprising a shell, a lamp component, and a fan. The shell is provided with an opening in the top. The lamp component and the fan are arranged in the shell, and the fan is located above or below the lamp component. An inducing agent placing table is arranged around the lamp component. The inner bottom of the shell is provided with a first adhesive layer. The periphery of the lower part of the shell is provided with exhaust holes. The inducing agent placing table can be used to place inducing agent to induce mosquitoes. The lamp component can emit light to attract mosquitoes, and mosquitoes follow the light and the smell of the inducing agent and fly to the inducing agent placing table. When the fan rotates, mosquitoes on the inducing agent placing table are blown down or drawn to the first adhesive layer, thus achieving the purpose of mosquito trapping; and when the fan rotates, the fan blades beat passing mosquitoes to death. The process of mosquito catching does not involve high current or high voltage. As the first adhesive layer is arranged on the inner bottom of the shell, contact with dust is avoided to a certain extent, and the adhesion force is ensured. Moreover, no peculiar smell is produced in the process of mosquito catching.
