Residents of Russian business-class residential complexes face year-round tick attacks inside building entrances, veterinarian of the highest category Mikhail Shelyakov has warned.

Shelyakov explained that entrance halls in business-class developments frequently feature indoor winter gardens with decorative plants and foliage. These indoor green areas can become breeding grounds for arachnids even during cold winter months, according to comments reported by the website of the radio station Govorit Moskva.
Dog owners living in these upscale complexes often allow their pets to relieve themselves inside the winter gardens during bad weather, the veterinarian noted. He stated that a tick can fall off a single dog, multiply within the warm garden environment, and continuously attack residents and pets throughout the year.
Indoor microclimates in upscale housing
Business-class residential developments in major Russian cities represent a popular segment of modern urban real estate, positioned between standard comfort-class apartments and luxury property. These developments typically feature enhanced communal amenities, including security concierges, underground parking, landscaped foyers, and climate-controlled indoor gardens designed to maintain living greenery through harsh winters. However, the combination of constant heating, high humidity, soil, and regular pet visits creates an artificial microclimate where parasites can establish permanent colonies.
The warning comes as Russians face a broader surge in pest activity following an earlier alert about a second wave of invasions by microscopic ticks, commonly called nano-ticks. In early autumn, more than 2,000 people sought medical assistance after receiving tick bites.
Autumn surge of microscopic ticks
Health experts attributed the autumn surge in tick bites to unusually warm and humid weather conditions across the region. They explained that young ticks of microscopic size are currently demonstrating the highest level of activity. Because these tiny parasites are extremely difficult to spot on clothing or human skin, they pose a hidden threat and can continue biting people until persistent frosts set in.
Seasonal patterns and health risks
Ticks are parasitic blood-feeding arachnids prevalent throughout temperate forests and urban parks in Eurasia. In Russia, outdoor tick activity traditionally peaks during late spring and early summer before subsiding as freezing winter temperatures arrive. Tick bites carry known health risks, as the parasites can transmit serious infections such as tick-borne encephalitis and Lyme disease. The emergence of indoor breeding habitats in heated apartment complexes means pet owners face potential exposure even when outdoor parasite populations lie dormant during freezing weather.
