1. A fluid mist sprayer system comprising:
- a source of treating fluid;
an electrical power source;
a pump for pressurizing the treating fluid as needed to discharge the treating fluid at a predetermined discharge pressure and flow rate;
at least one sprayer head configured to receive the pressurized treating fluid and to discharge the treating fluid in the form of a mist;
at least one flow conduit providing fluid communication between the source and the at least one sprayer head;
an ambient light sensor;
an electronic control unit that initiates a flow of pressurized treating fluid to the at least one sprayer head in response to sensed ambient light of predetermined intensity and duration, wherein the predetermined intensity and duration are those that occur at dusk and dawn; and
wherein the electronic control unit further comprises a light level discrimination module, a pump controller module, a power supply module, and a remote receiver module.

Abstract
An automatic mist-sprayer system comprising a control unit having electronic circuitry adapted to activate the sprayer for a predetermined interval in response to a sensed ambient light condition of desired intensity and duration. The system desirably further includes an electrical power supply and a plurality of spaced-apart sprayer heads. 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. Manual overrides and a remote receiving unit are also disclosed for use of the system at times other than dusk and dawn.
