Types of fleas and their characteristics

It feeds primarily on blood and body tissues, so needs to inhabit the body of other animals in order to survive.It measures only between 1 and 3.5 millimeters , so that at first glance we are not able to appreciate its shape well, ignoring that it has a hard body, with small legs and even tiny hairs.
Life cycle of the flea
A flea can wait for up to two weeks without feeding until the animal that will be its next guest approaches, is on some living being, in the grass or even in fabrics, such as carpets, clothes, among others.The truth is that they can be attached to clothes, so you can take them home without knowing it.
When you have found the guest, the female feeds on his blood until the moment of reproduction arrives.Then, lays his eggs , a maximum of 20 on each occasion, but is able to lay 600 in his entire life.Eggs fall from the fur of the animal, remaining in the spaces where it rests and other corners of the house.
After two weeks of maturation, the eggs hatch and appear the larvae .These feed on organic waste (dead skin, among others) until they have reached their maturation stage.After that, prepare a cocoon and when they leave it they are already adults, ready to repeat the cycle.
