How long can fleas live without food or a pet in an apartment?

Sometimes people mistakenly believe that fleas from pets do not threaten humans at all. Contrary to popular belief, parasites do not die immediately without a main source of food. According to the general idea, such parasites live quite a long time and reproduce intensively. It is difficult to notice dead fleas, because most often fleas are found crawling in the fur of pets. The reality is such that there are no long-livers among representatives of the species. One adult can live no more than three months. Regardless of this factor, a short period of time is quite enough to cause harm to the reproduction of new offspring.

Animal fleas will not live on humans permanently. The insect jumps onto a food source only when hungry and looks for blood vessels. Environmental parameters also have a significant impact on the lifespan of the pest. In a couple of months, fleas can:

  • Inflict one hundred bites on one victim;
  • Lay more than 300 eggs, which will then hatch into larvae.

How long do fleas live?

In favorable conditions for life, fleas live up to three months, during which the female lays approximately 500 eggs. The most comfortable conditions for parasites are a temperature of 21-26 degrees above zero, and a humidity of about 80%. When the temperature increases by 10 degrees, the development of fleas almost doubles. A decrease in temperature, on the contrary, leads to a slowdown in the growth of insects and an increase in life expectancy up to 2 years.

The reproduction cycle of insects also depends on the temperature regime. At optimal temperatures, the development period of the larvae is one month, at elevated temperatures - up to 10 days, at very low temperatures - up to 7 months. Then the eggs develop within 14 days; the insect remains at the pupal stage for about 20 days. In general, the full development cycle lasts from 10 days to one year, and life expectancy - from 1.5 months to several years.

Myths about flea lifespan

Among this type of insect, there are also real long-livers that parasitize ungulates. Tien Shan fleas reach sizes of up to 7 mm and can live for a year. Parasites in the northern regions often go into a kind of hibernation for the winter, but remain active for no more than 1.5 years. As for the more familiar types of fleas on dogs, cats and other animals, it is necessary to dispel several established myths.

Experts have long noticed that such pests cannot constantly be present on humans or other mammals. It seems to many that the insect’s usual habitat is the fur of a domestic animal, but in such an environment there are no suitable conditions. Fleas need to develop and reproduce calmly and comfortably, and the victim’s body is completely unsuitable due to numerous risks.

The parasite jumps onto the selected individual and begins to look for a suitable area to suck blood. A kind of banquet can last from a minute to several hours. After the meal, the insect jumps off and returns to its usual habitat. Due to the huge number of pests in the fur of a cat and dog, it seems that the flea does not leave the poor animal.

Taking into account such factors, when disinsection it is necessary to carefully search for insect breeding locations. Carefully inspect the following places in the apartment:

  • Animal bedding;
  • Skirting boards;
  • Carpets;
  • Floor cracks;
  • Garbage bins;
  • Old trash.

Pests rarely live in clothes, but if the area is highly infested, it is necessary to inspect the closet. The parasite feels especially comfortable when the source of food is freely available.

Don’t be surprised where a domestic cat gets fleas, because often people themselves bring several females of the pest from the street.

Like a number of other bloodsuckers, fleas are capable of spending long periods of time without food. For several months, the tiny creatures starve and do not hibernate. Regardless of life expectancy, an insect will not be able to reproduce without periodic reinforcement. This is why females become especially aggressive and try to drink more blood. In practice, we can give the following example: after a long stay, fleas will not die in your apartment and will begin to bite painfully immediately after the owners arrive.

How long do fleas live without food?

Fleas can go without food for about 2-3 months; their bodies are adapted to living in unfavorable conditions and the absence of a food source. But fleas cannot go on without food indefinitely, because they need fresh blood to reproduce and lay eggs.

When leaving the apartment with your pet for a long time, you should not expect that the fleas will die without the animal; they will definitely wait for the cat or dog to arrive and bite them. A peculiarity of country fleas and other types of fleas is their ability to sometimes feed on the blood of rats and mice, so they can wait for a long time for the owner with their pet.

Are fleas dangerous for humans?

The flea feeds on blood. To do this, she bites through the skin, injecting a substance into the wound that prevents the blood from quickly clotting. Along with saliva, pathogens that this parasite carries from other animals or people bitten earlier enter the wound. The wound is very itchy. A person scratches it, sometimes very hard, which causes the wound to increase in size and can become additionally infected. Cases of allergies to flea bites are quite common. In this case, the bite site becomes very red and swells. With multiple bites, a person’s body temperature may rise, general intoxication occurs, and fever occurs.

Fleas can cause the following diseases in humans:

  • brucellosis;
  • dermatitis;
  • dipylidosis;
  • pseudotuberculosis;
  • erythema, etc.

Fleas can also transmit typhus, anthrax, and helminths to humans.

All this means that fleas in the house can and must be fought.

Habitats of fleas in the apartment and in nature

In an apartment, dark and quiet places are suitable for insects to live:

  • animal bedding;
  • carpets;
  • upholstery of sofas and armchairs;
  • children's soft toys;
  • old clothes;
  • mattresses and bed linen;
  • behind the baseboard and under the linoleum.

On the street, blood-sucking parasites choose places of residence with close proximity to animals that can provide them with a source of food (squirrels, rabbits, hamsters, rats, gophers, etc.). Places for living most often include garbage cans, sand heaps, basements, bird nests, and the burrows of some animals.

There are several types of domestic fleas that live in close proximity to humans:

  • fleas of dogs and cats;
  • mouse and rat;
  • basement and ground;
  • bed fleas;
  • sandy.

Fleas are insects, although small, but they cause quite a lot of problems. Their bites are very painful and cause discomfort to the animal in the form of itching and irritation. In addition, these parasites are carriers of many unpleasant diseases. Therefore, it is important to get rid of them not only from pets in a timely manner, but also to remove them from all possible corners of the apartment.

Where do fleas come from?

Many people believe that fleas in the house are associated with pets. This is only partly true. Fleas can migrate from the street, from the landing, from neighbors. They can be brought from the street on your feet or shoes. The diet of these insects includes animal and human blood. A person will be able to guess that fleas have appeared in his home after he notices small bites on his body.

Where do fleas come from and what do they look like? These parasites can be up to 5 millimeters in size. Their body is flattened on the sides and has bristles. Thanks to such features, insects can easily, on the one hand, cling to animal fur, and on the other hand, move between the hairs. In birds, fleas can hide between feathers and in nests. Fleas have three pairs of legs and can jump distances that are many times their own size.

Flea bites are unpleasant because... cause severe itching, and in some - allergic reactions. In addition, fleas can carry diseases such as plague, hepatitis and others. Therefore, you need to get rid of them quickly.

Dangerous representative of the flea family

An exception to all representatives of the flea family is the sand flea, which lives in the tropics. In her regard, it is quite appropriate to say that fleas also live on humans. The female sand flea bites into human skin and penetrates the capillary. Saturation ensures the rapid development of eggs, as a result of which the individual increases in size and is not able to leave the injection site.

An ulcer with pronounced swelling appears at the site of the lesion. The maturation of the eggs lasts from 5 to 7 days, after which the female shoots them, shrinks and most often dies, remaining in the epithelium. In rare cases, a female is able to leave the wound alive.

Where do they live without animals?

Where exactly fleas live in an apartment depends on the location of food sources, which may include various animals and people. They especially often settle on the animal’s bedding, which provides them with constant access to food and helps maintain conditions suitable for reproduction and development.

If the animal is absent, insects settle mainly directly close to heat sources, for example, at the joints of walls, floors near heating radiators, bedding, furniture upholstery, carpets, soft toys.

Do fleas bite people or not?

Fleas can bite people, most often on the feet, ankles and legs. They can bite three times in a row. This is called "breakfast, lunch and dinner."

Usually the first bites do not cause damage to the skin, but if a person is exposed to fleas for a long period of time, a hypersensitivity reaction may develop.

Things to know

In order to understand in time what you are dealing with, you must know what flea bites look like on a person. This is the only way you can distinguish them from mosquito bites, bed bug bites, or an allergic reaction to food. Fleas cause the most discomfort when they bite. Allergic swelling may occur within a few hours. Its intensity will depend on the individual characteristics and inclinations of the person. In addition to the fact that the affected area itches, it also hurts a lot.

Since flea bites on humans look the same as mosquito bites, it is the pain of the bitten area that makes it possible to understand that this is a mark from another insect. Unlike mosquitoes, these bloodsuckers do not inject an anesthetic substance. Instead, only irritating saliva enters the body.
