Animals Drought has hidden mites in the earth’s crust – however, the number of mites is increasing in established areas, and late summer can reactivate ticks

The researcher estimates that late summer and fall rains may bring a peak of activity to ticks.

Tick in colloquial language, the incidence of ticks in the heat of July seems to be lower than in early summer, but hot weather does not kill ticks or affect their number, says the university lecturer Tero Klemola From the University of Turku.

If it is too toasted, the mites will not be able to lurk a passing host animal for a long time, but will have to return from the vegetation back to the soil moisture.

“Because of the heat, there are fewer tick-borne encounters, and then there will be fewer diseases caused by ticks,” Klemola estimates, referring to Lyme disease and tick-borne encephalitis.

Ticks the number has been growing for a few decades, especially in established tick areas, such as the archipelago and Lake Finland.

The increase is due to the good living conditions of mites and host animals.

“With climate change, the mite season is also longer, when spring comes early and autumns continue to be mild,” says Klemola.

The rains of late summer and autumn can bring a new peak of activity to ticks.

The same mite can live 3-4 years before reproduction. When a mite receives a blood meal as a larva or nymph, it can go back to the soil to develop for years.

Ticks to study prevalence and prevalence Punkkilive.fi service, to which anyone can report their fresh tick finding.

Punkkilivi wants to encourage those who move in nature or in the Urban Area to report their own tick observations. The notification can be made even immediately at the observation site with the help of a map of Finland. It is easily accomplished by phone and only takes a few minutes.

The Punkkilive service has been developed in cooperation between the University of Turku and the pharmaceutical company Pfizer.

The map of Punkkivi shows observations up to the northernmost part of Finland, but according to Klemola, the individual ticks observed may have migrated from the south. According to Klemola, established tick populations are at their highest in Sodankylä. The tick can remain invisible on the skin or in the dog for several days, so individual tick observations in Saariselkä and other Lapland resorts may be due to tourism.

Klemola says that in the late 1950s, the tick border ran along the Kokkola – Joensuu line, but the border has slowly risen hundreds of kilometers across the Arctic Circle. If mites ever spread to the far north of Lapland, they would come through the temperate coast of Norway, he estimates. Until Fell-Lapland, he doesn’t think the mites are spreading yet.

According to Klemola, Punkkilive is most useful when people can also record observations in early spring and late autumn. In this way, the season of mite activity in different parts of the country can be monitored.

The mite season can last from March to November, as long as there is no snow in the country. From snowy ground, ticks do not jump on the host animal.
