Flea survival is significantly impacted by temperature. While adult fleas can survive for a short period in freezing conditions, prolonged exposure to temperatures below freezing can be lethal. Their eggs, larvae, and pupae are even more susceptible to cold. For example, flea populations often decline dramatically outdoors during winter months in colder climates.
Understanding the relationship between temperature and flea viability is crucial for effective pest control. This knowledge allows for targeted treatments during warmer months when flea populations thrive and helps predict potential infestations after periods of cold weather. Historically, seasonal temperature fluctuations have been a natural control mechanism for flea populations. However, with climate change and the increasing prevalence of heated indoor environments, fleas may be active for longer periods, necessitating year-round vigilance.
