Fleas are quite resilient and can survive indoors during winter months. They thrive in warm, humid environments, which can often be found inside homes, especially with central heating. Adult fleas can live for several months without a host, and their eggs can remain dormant in carpets, upholstery, and pet bedding until conditions are favorable for hatching. To manage fleas indoors during winter, it’s important to regularly vacuum your home, wash pet bedding, and consider using flea treatments for your pets. Additionally, maintaining a consistent temperature and humidity level can help deter flea infestations.
