While bed bugs thrive in warmer temperatures, they are surprisingly resilient and can survive in colder climates. Exposure to freezing temperatures for an extended period can kill them, but they often find ways to avoid such extremes by seeking refuge indoors, particularly in heated human dwellings. For example, a heated home in a region experiencing sub-zero outdoor temperatures can provide a suitable harborage for these pests.
Understanding the relationship between temperature and bed bug survival is crucial for effective pest management. Knowing that these insects can persist through colder months, albeit with potentially slowed reproduction rates, emphasizes the year-round vigilance required to prevent and control infestations. Historically, control methods have focused on chemical treatments, but integrated pest management strategies, including heat treatments and vigilant monitoring, are becoming increasingly important, especially given the adaptability of these insects to varying environmental conditions.
