Where Do Fleas Go in Winter?

Where Do Fleas Go in Winter?

Many people think that they can stop flea treatments around the time that the clocks change. They assume that the cold and damp will make these parasites disappear until the spring, rather in the same way that bees and other more friendly and useful insects hibernate.

Unfortunately this is not true, fleas do not die off when days get shorter and the weather gets colder. The flea can survive winter no matter how cold it gets! The flea egg can even survive the cold outside, when it is even too cold for the dogs to venture out voluntarily! How can fleas survive winter cold, snow and ice?

They do this just like bees, flies and other outdoor bugs, they hibernate. Unless the flea eggs are killed off outside and inside your home, they will continue to hatch and be a nuisance to your pets and family.

Although fleas in the Larva, Pupa and Adult stages of the life cycle may die off outside during the cold winter months, the flea egg can survive just to hatch in the spring. When the flea egg hatches it is able to start the whole flea life cycle over again.

There are a number of natural ways of disposing of the flea eggs in the immediate proximity of the house, in particular in places where the dogs and cats may relax/sleep. This is the most likely place for there to be concentrations of flea eggs. However if you live in the campo you cannot possibly know the location of, or concentration of, flea eggs. All you can do with these outside infestations is to avoid those areas most attractive to fleas when it gets warmer and to ensure that your dogs and cats are protected by the only non-toxic repellent, the CatanDogís Antiparasite Tag.

Are you, and your cats and dogs, therefore, going to be free from these dangerous and irritating bugs during the cold season? The answer is NO!

Fleas can live in carpets, soft furnishings, hardwood floors and even in tiles and concrete. They can also hibernate for up to two years. This may be why if you move into a new house the house can become infested with fleas. Once the house warms up the eggs will hatch and they will look for a host to feed on = your cats and dogs!

You do not have to move to a new home to have flea infestations in the home. There will always be fleas in the home. What are the best treatments? There are a large number of natural products to kill the eggs, the pupae and the fleas themselves, but the best is to wash all bedding in the house and also the dog bedding. If this is not suitable for washing buy a new clean, flea free, animal bed. There are natural products to clean carpets with. These should kill the fleas at the various stages of their life cycle. Then, everything possible should be vacuumed on a daily basis. This includes moving the furniture and going right up into the corners! You may be fighting a losing battle to totally eliminate all traces of fleas in their various stages of development but you will notice the difference.

At the same time you should be treating your cats and dogs with a natural flea treatment, as you would during the summer months. If you are using spray products only buy them from veterinarians as some products on general sale can be harmful to your pets. If you use a dog spray on a cat it can often be lethal on account of the toxicity being more than the catís body can tolerate. There are too many tales from veterinary clinics which back this up.

Believe it or not, the fleas you are seeing on you and your pets are only 5% of the total flea population living in your home! This statistic demonstrates why fleas should continue to be a concern once the winter arrives! Do not think they are a Spring, Summer and Autumn pest, they are a pest for 365 days a year!

Life Cycle of Ctenocephalides Flea

common cat flea, found on both cats and dogs


A female lays about 2,000 eggs in her lifetime. In one day, a single female flea can lay up to 50 eggs. The eggs aren't sticky so they quickly fall off your pet and into areas of your home. In 2-10 days, the eggs hatch.


After hatching, the larvae head toward dark places around your home and feed on "flea dirt," flea feces containing partially digested blood from your pet. The larvae grow, molt twice, and then spin cocoons, where they grow to pupae.


Immature fleas spend approximately 89 days in their cocoon. During this time, they continue to grow to adulthood, waiting for the signals that it is time to emerge. A flea can stay in this state for years.


Full-grown adults detect heat, vibrations and exhaled carbon dioxide from inside their cocoons, telling them a host is nearby. The adults leave their cocoons, hop onto a host, find a mate and begin the life cycle all over again.
