Many pet owners assume fleas disappear during the colder months, but that’s a myth. In this episode, we explain why fleas can still survive and reproduce during winter, how infestations often begin with just one flea, and why year-round prevention is the most effective way to protect your pets and home.
Podcast Summary: Fleas in Winter – They Do Exist!
- Fleas do not disappear in winter, despite the common belief that cold weather eliminates them.
- Most fleas affecting dogs and cats are actually cat fleas, which can infest both species.
- While colder temperatures slow the flea life cycle, they rarely stop it entirely in most parts of Australia.
- Modern pets often live indoors or in sheltered areas where temperatures remain warm enough for fleas to survive.
- Fleas reproduce extremely quickly, with a single female capable of laying thousands of eggs.
- Even one flea introduced into the home can lead to a major infestation within weeks.
- Flea pupae can remain dormant for months, waiting for vibrations such as footsteps to trigger hatching.
- This is why homes that appear flea-free can suddenly experience outbreaks.
- Pets can pick up fleas from other animals, neighbouring pets, visiting animals or shared environments.
- Year-round flea prevention is the most effective way to avoid infestations.
- If fleas are already present, treatment must involve both the pet and the home environment.
- Washing bedding, vacuuming carpets and using environmental treatments can help reduce flea populations.
- Fleas commonly live in carpets, bedding and areas where pets sleep or spend time.
- Consistent preventative treatments for all pets in the household are important.
- Stopping flea treatment in winter can allow flea populations to build and explode in spring.
- Preventing fleas early is much easier than dealing with a large infestation later.
