Residents in several regions of Russia have reported a sudden influx of bats entering residential apartments and public areas, according to reports highlighted by news channel Baza.
Reports of bat sightings have emerged from Leningrad Oblast, Nizhny Novgorod Oblast, Omsk Oblast, and Zabaykalsky Krai, as well as the republics of Tatarstan and Buryatia. The animals have been seen circling outside residential buildings, entering stairwells and building entrances, and flying through open windows, balconies, and doors into private apartments.

The affected regions span across European Russia, Siberia, and the Russian Far East. Leningrad Oblast surrounds Saint Petersburg in the northwest, while Nizhny Novgorod Oblast and Tatarstan sit along the Volga River basin in central Russia. Omsk Oblast and Buryatia are located in Siberia, with Zabaykalsky Krai extending into the far eastern territory. Telegram news channel Baza, which frequently monitors regional incident reports across Russia, first drew wide attention to the trend.
Causes of bat movement
Ecologist Vladimir Pinaev attributed the widespread influx to seasonal migration patterns and the natural dissolution of maternal brood colonies. He explained that young bats and migrating individuals actively search for new roosting spots during this period, frequently mistaking tall apartment blocks and window openings for natural cave structures or rock crevices.
Maternity colonies are established by female bats in early summer to give birth and raise offspring. Once the young bats learn to fly by late August, these colonies break up, sending juvenile bats into surrounding areas to find winter hibernation quarters. Urban high-rise buildings create artificial canyons that mimic the cliff faces and rock formations where wild bats traditionally seek shelter.
Safety guidelines for residents
Pinaev advised residents who find a bat inside their living quarters to open a window or turn off the lights, noting that the animal is highly likely to fly out on its own. He warned against handling bats with bare hands, stating that bites or scratches can transmit rabies.
Rabies is a severe viral infection affecting the central nervous system of mammals. The disease is transmitted primarily through saliva via bites or scratches from infected wildlife, including bats. Health authorities recommend that anyone bitten or exposed to a wild mammal seek prompt medical evaluation and vaccination.
Seasonal outlook and prevention
Ecologist Ilya Rybalchenko previously warned that the period of heightened bat activity will continue into September. To lower the risk of bats entering living spaces, Rybalchenko recommended installing mosquito netting on open windows.
