Abstract

A portable, light-activated, mist sprayer system comprising direct current power supply, an ambient light sensor, electronic circuitry that evaluates an electrical signal received from the light sensor to determine whether a 'dusk' or 'dawn' light condition exists; a container of treating fluid at a desired concentration; a motor and pump that are activated at the appropriate time as determined by the sensed light condition; at least one sprayer nozzle that will dispense a mist containing the treating fluid whenever the pump is operating; and a timer that turns off the pump after a preset interval to terminate the spraying cycle. A preferred utility for the system of the invention is spraying dilute solutions of insecticide or insect repellent during the periods of significant insect activity that typically occur around dusk and dawn. An RF receiving unit is also disclosed for optional activation using a remote transmitter.
