The classic way of dealing with flies - adhesive tape. Tried the inventors to fight the same way and with the mosquitoes. Developed a special composition of odorous the liquid was put on paper with adhesive backing. But the result was quite depressing - flies sat on the paper like honey, but the mosquitoes... they chose themselves inventors. However, all this was predictable. Because mosquitoes are armed quite sensitive termlocation, which makes them easy to distinguish animals and humans on the thermal background of other objects.
Then, the inventors decided to go to the trick. Took the tape with two-way the from high voltage metallized paper capacitor. The ends of the tape that served as plates, locked together. Turned out the two wires connected consistently, from which their ohmic resistance was formed. Now it remained for small - to connect the current source, for example, the battery or the unit food for 6-12 mo, using small wire resistance, which you can adjust the amount of current and thereby heating tape.
When the device was ready and the circuit is closed, the first "bloodsuckers", being nearby, took the bait. No matter how tricky the mosquito, but it was impossible to cheat.
This is a wonderful device to easily perform yourself. How it is arranged, it is clear from the figure. But this does not mean that you must adhere to such design. It can be anything - a portable, fixed... it is only Important to pick up through the resistance of the resistor a "favorite" mosquitoes temperature Yes to apply tape adhesive like "World" or "Muxed". And to the darkness himself accidentally not stick, can be equipped with a trap low-power red diode, a kind of beacon for the midges.
