Many who lived in Soviet times recall: then they spoke much less about ticks. Just because a real large -scale struggle fought with them!
After the connection between the ticks and the encephalitis virus was identified in the thirties, the authorities urgently began to look for ways to protect the population. The main weapon was the DDT chemist, which was treated with huge territories – from forests to parks. They sprayed him even from the air. The effect was tangible: the ticks disappeared for several years, but nature suffered with them, and this thought about this only after decades.
Later, instead of DDT, they began to use milder means. Residents of dangerous regions made mandatory vaccinations against encephalitis. They were received by everyone who worked or spent time in nature – from geologists to guides. Even practical students could not get to the infected territory without a vaccination certificate.
The methods of that time may now seem rigid, but it was they who helped to keep the situation under control, and the effect was such that for many years the ticks ceased to be a terrible topic in every spring news release.
