A mosquito trap device includes a housing having an air inlet and an air outlet. A wind channel is formed between the air inlet and the air outlet. An ultraviolet light module is mounted in the housing and is located adjacent to the air inlet. A wind module is mounted in the wind channel of the housing. A mosquito detaining device includes a tube and a net. The tube is mounted in the wind channel and is coupled to the wind module. The net is mounted to and covers an end of the tube adjacent to the air inlet. A controller is electrically connected to the ultraviolet light module and the wind module. The controller is configured to output a pulse width modulation signal to the ultraviolet light module. The pulse width modulation signal has a frequency of 25-512 Hz.
