Conditions for fleas to survive, how long fleas can survive

The conditions for fleas to survive include the following:

1.Temperature: Fleas prefer temperatures ranging from 20 to 30, which allows them to survive in human habitation.

2.Humidity: Fleas prefer moist environments because moist fur provides the moisture they need.

Humidity needs to be at least 60% or higher. In drier environments, fleas get water from animals, but this depletes the water in the animal's body, causing the animal to become dehydrated.

4.Host: Fleas need a host to provide the environment and food they need to survive. They usually choose mammals because the body temperature and humidity of mammals are suitable for fleas to survive.

In addition, a suitable living environment is also an important condition for the survival of fleas. If the environment is not warm, moist or dark enough, fleas will not survive. Therefore, in winter, especially in northern regions, due to the higher temperatures caused by indoor heating, and at the same time to prevent indoor drying, people may resort to increasing indoor humidity, which may be conducive to the survival and reproduction of fleas.

It is important to note that although fleas have strong vitality, there are ways to get rid of fleas. For example, clean your room frequently, keep your environment clean and dry, wash your pets regularly, and use special flea sprays and insecticides. In conclusion, understanding the living conditions of fleas and taking corresponding measures can help us effectively prevent and control flea breeding.

Adults usually live in mammals, and a few in birds. The larvae are cylindrical, free-living, have chewing mouthparts, and feed on adult blood or organic matter.

Adult fleas can go up to 12 months without eating anything, and at every chance they get their nutrients by sucking blood. Since fleas have no specific host, they can be parasitized on a variety of hairy animals, even hairy inanimate objects (such as carpets). Therefore, controlling fleas on pets alone will not eliminate fleas.

The female flea will ovulate on the host (animal) after sucking blood, the eggs are white as the size of salt grains, non-sticky so they are easy to fall, and the larvae may hatch within 2 days to 2 weeks after being laid, and the larvae are white or milky white; They will usually hide in cracks in the floor, under carpets, in pet beds, and the larvae will only eat a little something, such as adult feces or organic debris in the environment, and then they will turn into cocoons. After that, the fleas can turn into adult fleas within 7 days to a few months, depending on the environmental conditions. When there are many fleas on the pet's body, its eggs and black flea droppings can be found together, and if red stains are found, they are formed after the feces are wet.

Fleas belong to the class Insecta. Fleas are very small and have many inverted stiff hairs that help them move within the hair of the host animal. It also has two strong hind legs, so it is good at jumping and jumping.

Seven or eight inches tall. Females lay their eggs in dusty corners, small holes in walls and floors, or they can lay on animals, landing or migrating as the animals move. Egg white, approximately.

In four or five days, white footless larvae hatch and feed on organic matter from dust and flea droppings. After two weeks, the larvae spit silk and dust to form cocoons and pupate in them, and after another two weeks the fleas come out of the cocoon. If a flea touches an animal, it immediately sucks blood.

Fleas have a lifespan of about 50 days, while fleas that parasitize humans can live for 518 days.

Some species of fleas can give birth throughout the year because the adult parasitic dates live on the body surface of homeothermic animals. The reproductive activity of some fleas is synchronized with the life cycle of the host animal, and they are affected by environmental factors and climatic conditions.

A few days after penetration, the stool was observed in the scanning electron microscope The eye of science How harmful are the source of science fleas? Fleas have been on Earth for about 60 million years. It is ectoparasitic in mammals and birds.

However, there are cases where they survive for more than a year. Fleas and the "plague" of terrible "plagues" that have occurred in history, including the plague. Plague can be divided into bubonic plague and pneumonic plague, bubonic plague can mainly be caused by wounds and digestion.

Female fleas suck blood and lay eggs, which are white or yellowish in color, and a female flea can lay more than 1,000 eggs in her lifetime. The eggs undergo 2 to 12 days to hatch into maggot-like larvae, the larvae are always far from light and prefer dark places.

Ticks and fleas on dogs can also reach people, and the situation is even worse when they expand their range of activity. Therefore, it is necessary to do a good job of deworming and strangling fleas and ticks before the cradle of birth.

Eliminate fleas: 1. Pay attention to personal hygiene: if fleas grow, it may mean that the room environment is too humid and the personal hygiene is poor, it is recommended that the room should be cleaned, maintain air circulation, and develop the habit of bathing frequently.

2. Drug killing: patients can use insecticides in the corner of the room to kill drugs, and if necessary, they can use the diluted disinfectant to wipe the room repeatedly, which can play a role in disinfection and sterilization.

3. Ultraviolet radiation: It is recommended that patients can expose the mattress bedding to ultraviolet rays. <>

1. The resistance of microorganisms on fleas

Fleas have a strong immune system that can defend against many diseases and viruses. Fleas have a lot of microorganisms on their bodies, which help fleas digest food and also resist attacks from foreign microorganisms.

The immune system of fleas is mainly protected by molecules secreted by its surface. These molecules are similar to antibodies and cytokines in the body's immune system, specifically binding to pathogens, preventing them from invading fleas.

2. The ability of fleas to suck blood

Fleas feed on the blood of their hosts to stay alive and need to suck 15-20% of their body weight per day. Their mouthparts draw blood into the body quickly and release a type of saliva that contains an anticoagulant, making it less likely to clot.

Blood is important for fleas to survive**, but it can also be dangerous. While sucking blood, fleas can also bring germs and viruses into the body, causing harm to the host and even spreading diseases.

3. The ability of fleas to adapt to drought

When threatened by a dry environment, fleas can quickly go into a dormant state to adapt to drought conditions. This state is known as the "pupal state", and fleas can survive for months until the humidity returns to a certain level before resuming their activity.

Fleas also have a very athletic survival strategy. When faced with drought or danger, fleas can leap up and get over the predicament. It is extremely capable of jumping, not only jumping into pets in different positions, but also covering long distances.

4. The ability of fleas to reproduce

Fleas have a very strong reproductive ability, laying about 500 eggs at a time, and the incubation time is only 2-12 days, and it can complete multiple metamorphoses and become a complete adult in a hungry state in just a few days. In addition, they are very fond of spawning in clean places.

In addition, fleas can also breed a lot of new species, many new flea varieties are also specially adapted to their host desert, aquatic, herbivorous flea morphology changes greatly and is an ectoparasitic colony, and only for a specific host, the foot structure changes the way it works, and other conventional fleas can not burrow into fine fluffy hairs or hard shells, which is its strong adaptability in reproduction.

The largest and most common host of fleas is rodents, and dogs, cats or humans are also the main hosts of some kind of fleas, so fleas will not only parasitize animals, but also parasitize people, and they all suck blood.

The habitat of fleas depends on the habits of the host and the influence of external factors, they like places with poor hygiene, and they are easy to hide in the hair of the human body, as well as clothes, bedding, etc., so they should do a good job of personal hygiene to prevent the growth of fleas.

Flea prevention measures:

1. Do a good job of household ventilation, and regularly expose the bed and bedding to the sun.

2. Keep the indoor and outdoor environment clean and tidy, and do not pile up debris inside and outside the house, underground garage and other places. While preventing fleas, it is necessary to pay attention to rodent prevention, and at the same time avoid the proximity of stray cats and dogs.

3. When cleaning, clean the gaps in the walls, bed sheets and carpets thoroughly, it is best to use a vacuum cleaner, and clean up the garbage in the vacuum cleaner in time. Hall stove.
