I have been competing with ants for a long time and, I must admit, I constantly lost. While the eight-year-old Kuzma Sergeyevich, amusing himself with his shooters, advised: "Grandfather, and you, like me, - by electric shock!"
Indeed, on pastures for gobies and heifers, an electric fence was invented, for caterpillars on trees - hunting belts, I decided to try out an electric belt.
I cut off insulation on one side of a flat two-wire wire along the entire length, i.e. bared two copper conductors (Fig. 1). Vein spacing
about 2.5 mm. I wrapped the tree trunk with bare veins outward in several turns of this wire. On one side of the wire, I connected a 1.5 volt AA finger battery to the ends of the wires, left the other ends of the wires apart - it turns out, the circuit is open (Fig. 2 and photo). The battery and cores were secured with a tube from the marker body, rubber bands from the camcorder and tape.
The principle of operation of the electric belt: when you try to climb over the annular barrier (through the bare veins), the ant shorts the circuit with its body and falls under voltage.
Result: some ants fall off immediately, others creep away to their own to share their life experiences. To scare off is humane, and without chemistry ...
