A step above the basic Black Hole model, Black Hole Plus includes an automatic sensor and louver system. Switch the device to automatic mode to activate in darkness, when mosquito activity is at a minimum. Use manual mode if standard Black Hole operation is needed, e.g. for protection while you sleep.
Don’t repel the mosquito menace just to face it again another day, Seek the potential of the Black Hole and you are one step closer to eliminating it entirely
