During the winter fleas tend to seek the nearest source of warmth. It can be in a house, or on pets. Each flea can lay up to 20,000 microscopic eggs everyday. If you see a flea on your pet, then its a safe bet that in a week or so there will be thousands more. I would recommend if you have pets, strictly indoor or not, that they be on a year round flea and tick prevention.
In the winter, they have to do it in the hive because it is too cold to go outside. They then clean everything up when the weather gets warmer. In the summer they do it outside.
Fleas can survive in cold temperatures, but they are less active in freezing conditions. However, fleas can survive on a host or in sheltered environments where they can stay warm and protected from the cold. It's still important to take measures to control fleas in all seasons to prevent infestations.

yes, a house dog could get fleas...of course you go outside and walk around, your shoes touch the ground and your clothing picks up many things. When you get home, fleas can be on what your wearing and transferr to your dog. Also when you like your dog outside, you dog can catch fleas as well.
It's for the temperature. When it gets too cold they go up in your body and go down when it's warm. If they were inside they couldn't do that. The sperms don't feel good when it's too cold and too warm.
go outside of the super market and then go down and you'll see the path to cold storage
It is definitely possible to spread fleas around. Fleas go everywhere, so if you go somewhere with fleas, chances are that they are on you, and will soon be in your house, on your pets, or wherever you go. Until you take the right procedures to get rid of them. Fleas spread, and multiply like crazy.
If it's too cold for you then it's too cold for your hamsters.
yes
Carnations would suffer from the cold. So if your winter is cold, then the carnation will die eventually if you stay outside long enough.
It will be radiated into outer space.
Depends on the bird. It puffs up when it gets too cold. Some birds it has to be at least 70 degrees, but some birds are more hardy and are happy to be outside when it is 60 degrees. Do not let it go outside but keep it in a cage. If it is very tame and has clipped wings then you can take it on your shoulder if there are no cats or other predators.
