Electronic fly population control apparatus

A device for controlling the population of flies within a building by applying short duration high voltage bursts to destroy the nervous system of the files, said device comprising:

• (a) an electronic circuit means for generating high voltage bursts with sufficiently high voltage to destroy the nervous system of a fly, said bursts being of insufficient power to cause ignition of materials within the vicinity of said building, said circuit means having:
• a high-voltage transformer having a primary coil and a secondary coil;
• a triac switch connected to the primary coil;
• a pulse generator connected between said triac and an oscillator, for controlling said triac to turn on to allow current to flow through said transformer;
• an oscillator connected to said pulse generator, for controlling the pulse repetition rate of said pulse generator, and
• (b) roosting means connected to said secondary coil, providing a roosting surface for said flies, said roosting means having a pair of parallel conductors extending between two points within said building, said conductors being spaced 1/8 to 3/16 in. apart and neither of which conductors being rounded to any point of said building;
• whereby when a power source is applied to said circuit means, said pulse generator has a pulse width of 1-20 milliseconds, and said oscillator has a frequency of 0.2-1 Hz, thereby conduction of current flowing through said triac is limited to occur once every 1-5 seconds, and therefore a high voltage is being generated in the secondary coil and presented between said conductors only in short burst simultaneously.
