This winter, the Helsinki metropolitan area is experiencing an unprecedented increase in rat sightings, largely attributed to feeding shortages in the natural environment. According to Petri Metsälä from Anticimex, a pest control company, sightings have increased by about 25% compared to previous, milder winters, as rats are compelled to search for food where humans leave it. This situation has prompted a noticeable rise in complaints and reports of rat activity across various locations.

Metsälä emphasizes that this trend is not isolated to the capital but reflects a broader issue as similar reports are coming from multiple cities across Finland. He points out that the problem is worsening because of the intense cold, which forces rats to venture closer to human habitats in search of sustenance. Cities are currently struggling with increased rat populations, and public health officials are warning communities to be vigilant.

In relation to this, health officials in Tampere have observed an uptick in rats seeking food and attempting to infiltrate buildings, with local health inspector Matti Naukkarinen highlighting that winter conditions have significantly influenced this behavior. As the ground freezes, natural sources of food become scarce, leading rats to urban areas where waste piles and bird feeders provide accessible nutrition. The community's awareness and prompt action in managing waste are critical to mitigating this rodent situation.
