Fleas in the house are a source of trouble. Jumping on the legs, and even more so, fleas scurrying around in the bed or in the hair, plus irritating bites - all this gets on the nerves. In the advanced stage of infection, self-removal of domestic fleas in an apartment takes 4-6 weeks. But this problem can be solved faster if you start taking action in the first week after fleas appear at home.

But adult insects make up only 5% of the flea colony in the apartment. In addition to adults, eggs, larvae and pupae mature in the house. Immature stages live in floor carpets and animal bedding, where they feed on organic waste. The larvae also hide in cracks in the floor and baseboards, and in accumulations of dust. Due to their microscopic size and secretive lifestyle, it is difficult to see larvae and pupae, and therefore 95% of the flea population in an apartment is hidden from view.

How to tell if there are fleas in a bed

Fleas do not make hiding places in a person's bed, such as bed bugs. Adult fleas, if they appear on the bed, do so only to bite a person and immediately disappear. Eggs and larvae are usually concentrated on the floor. But if a cat or dog sleeps on the bed, then fleas can get comfortable there.

Having made sure that these are fleas, we move on to the next stage.

What to do if there are fleas in the bed

Although human blood allows the adult to survive, it is not suitable for normal flea reproduction. In addition, fleas are physiologically adapted to living in fur, where they feel confident and comfortable. For example, a flat body covered in spines and backward-facing bristles helps fleas attach to the fur and prevents them from being removed.

A flea manages to cling to smooth human skin without falling off only on the tenth attempt. And even after this, the insect has a slim chance of being able to inflict a bite without being noticed. And yet, in rare cases, bloodsuckers attack people. For example, if the owner likes to sleep on the bed cuddling with a pet, at some point fleas may appear in the hair.

Or another situation: there are no longer any animals in the house, but the fleas remain. Having no other food sources, the parasites begin to attack humans. In this case, the action plan is as follows: wash in hot water home clothes, bed linen and thoroughly wash your head and body in the shower, lathering generously with shampoo. But to completely get rid of fleas, you will need to treat the apartment. Some time after disinfestation, control methods will help evaluate the result.

insecticidal aerosols Raptor, Raid, Combat, Executioner, Gett, etc.

Human flea development cycle

The development of human flea beetles is no different from other species. Differences are observed in the size of the adult individual, and in the female’s ability to lay a larger number of eggs (about 2000 over the entire period of life). The bloodsucker has 4 stages of development: eggs, larvae, cocoon, adult. Having drunk blood, the female throws out eggs that end up anywhere. This could be clothing, furniture, carpets, animal hair, bedding. The eggs mature in 2 days or more.

The hatched larvae feed on processed food from adults and other waste. They go through several stages of development, and then pupate and mature. They wait for special conditions for their cocoon to emerge. The period of development from an egg to the release of a new individual can take from 15 days to a year, or even more.

Types of human fleas

As you know, there is one type of human flea beetle - Pulex Irritans. Knowing that these insects do not live permanently on the body of their prey, but look for secluded places, they are conventionally classified as:

linen;
furniture;
sandy;
indoor;
basement

The flea is a blood-sucking insect and belongs to the order of arthropods. The length of its body is only 1-5 mm, but there are some rare species that reach 1 cm. Fleas do not have wings, but have strong and long limbs, thanks to which they move. Some individuals can make long jumps to considerable heights.

If environment contributes, the flea lives on average from several months to 2-3 years, and can go without food for a long time. The color of the insect varies from yellow to black, depending on its species and habitat.

The main reasons for the appearance of fleas in apartments:

migration of insects from neighbors;
from public corridors and entrances;
from pets;
dust (for example, after repair);
living in lower floors or basements;
unsanitary conditions and lack of hygiene;
from people's clothes and shoes;
from rodents (rat fleas).

How to remove fleas

In addition, they can be carriers of infectious diseases such as hepatitis, tuberculosis, typhoid, plague, malaria and other infections.

Penetrating into a home, they settle in their favorite places:

in carpets, bedspreads, linen boxes, upholstered furniture;
in bed;
in places where pets rest;
under baseboards, window sills and wallpaper;
in other secluded places, grooves and crevices.

Cat and dog fleas

If your pet suddenly begins to itch and behave restlessly, then most likely there are fleas in its fur. They can be easily detected by examining the areas behind the ears and belly of the animal. It is there that they most often lay their larvae, and if, for example, you lower a dog into water, the fleas will begin to actively jump on the pet’s head.

There are several ways to get rid of insects from cats and dogs:

special detergents and shampoos for animals;
drops on wool;
collars (usually as a preventive measure);
sprays and aerosols.

The greatest effect can be observed from sprays and aerosols. When using them, one must take into account the fact that animals often lick their fur, and the products contain toxic substances that can cause poisoning. Therefore, before choosing a method for eliminating fleas from an animal’s fur, it is advisable to consult a veterinarian.

Bed and linen fleas

Most often, fleas do not live permanently in laundry. They are forced to move around in search of food, but can lay eggs in the laundry. It's unpleasant when fleas infest your bed. It is in this place that they are most comfortable, since in a dream a person often does not feel bites and bloodsuckers can calmly feed and reproduce.

If, after sleep, red itchy bites appear on the body, mainly on the legs, and small black spots or dots on the bed linen, then this indicates the appearance of fleas.

Then the following measures must be taken immediately:

wash linen drawers and cabinets with laundry soap or vinegar;
vacuum upholstered furniture;
wash all laundry in hot water;
iron things thoroughly;
Take blankets, pillows, mattresses out into the cold for a while or warm them well in the sun.
