Whenever we see our pet suffering because of this bug, the first thing that comes to our mind is: “Where did they come from?”. It is a difficult question to answer since you have to weigh in some serious causes that could be: warmth, food, darkness, movement, and your breath.
So, you have to classify how these disgusting insects are attracted to these things.
This is one of the things they most like. Living in warm places, since their preferred temperature is over 18 degrees, can bring them in quite fast, so try to keep your temperature a bit lower, so you don’t get this terrible insect in your house. They are going to get into your pet’s fur as it keeps them warm, and they have a chance to take advantage of your pet too.
However, some of them can live in winter since they get attached to the hosts (pets), giving you a headache and having to vacuum your house from top to bottom to get rid of them.
When a flea is on top of your pet, it will make sure to lay as many as 50 eggs on it, so it can continue the legacy. However, these eggs being in your pet’s fur doesn’t grant them to stay there. The stickiness reduces as days pass and these eggs fall in different parts of the house, on your carpet, floor, among others, leaving them the chance to crawl to dark places, so they can foster and grow.
These eggs tend to feed on the faeces that have been left by the big fleas and then develop into pupae and grow a cocoon from which they will go out looking like an adult flea provided that there is food around.
Their main food is blood. These bugs are parasites and tend to feed off the first living being they can find. Your pets are very vulnerable since their fur is a great place to be as it keeps them warm and gives them a sense of hiding.
You have to be careful if you have an infestation at home, since some pets can be allergic to their saliva and develop more serious illnesses. Moreover, sometimes humans are their targets, although it is not that common, but beware of a flea bite, it can cause a lot of trouble.
As long as a flea finds some movement, they will not get out of the cocoon they have been living in because if they don’t feed immediately, their fate will be death. They can also detect carbon dioxide that comes from the host, so they know it is a good source of food.
