Most people practice good hygiene. A person's body temperature is 36.6 degrees, which is significantly lower than that of animals, and the meager amount of hair on the body contributes to the fact that a person is a carrier of fleas, but they cannot constantly parasitize him.
The human flea adapts perfectly to its environment and visits humans only while eating.
The most common types of fleas
- Dog and cat fleas. Their bites on the body appear when a person comes into contact with animals.
- Rat. They are more widespread in rural areas. This type of flea carries the most dangerous diseases.
- Avian and other species.
Flea bites can cause discomfort, cause allergies and cause illness. Typically, bite marks on the skin completely disappear after 4 days.
Important!
An insect attack is easy to notice. Boha can move quickly, so nature has not endowed it with an anesthetic enzyme in its saliva. A flea bite is quite painful.
Different types of insects and the damage they cause
Sand (ground) fleas are very dangerous to human health. Bites cause purulent abscesses because the insects penetrate the skin and multiply there. This can lead to the development of serious diseases. Prevention includes wearing socks and shoes, keeping your home clean, and washing your feet after walking in contaminated areas. These measures will help avoid infection from sand flea bites. Treatment is possible in a surgical setting: the flea is removed with tweezers, the wound is disinfected and a bandage is applied.
Pets are also susceptible to attacks by these insects. Both cats and dogs can have fleas. An animal that is affected by these parasites shows anxiety, bites itself, scratches itself, trying to catch the flea with its teeth. Dog (cat) flea bites cause allergic dermatitis in animals.
Features and treatment of the consequences of a flea bite
The human flea is almost no different from its counterparts (cats, dogs, rats, etc.). Its body is flattened laterally, equipped with strong hind legs for making long and sharp jumps. A flea can cover a distance of half a meter in a microsecond. Its oral piercing-sucking apparatus is small, so when the skin is pierced, the flea plunges almost half into it. Its body forms a right angle with respect to the skin of the victim when it bites. The dense chitinous shell and flattened body make the parasite immune to physical influences (it is almost impossible to catch or crush a flea). The bloodsucker is not constantly on a person, spending most of its time in other places.
An adult female produces several eggs in one clutch, which develop within 14 days in cracks in the floor, walls, carpets, and upholstered furniture. The larva hatching from the egg goes through several molts and soon turns into an adult. A female can lay more than 500 eggs in her entire life (which is from 1.5 to 3 years).
Fleas that bite animals are almost no different from humans. They have the same size, color, life expectancy. A more thorough study of the parasite and determining what species it belongs to is possible only with the help of special equipment.
Specialists in Khanty-Mansiysk have all the means to detect insects and destroy them instantly.
Important!
Wounds after flea bites take a long time to heal, they can become inflamed and fester.
In order for blood to flow into the digestive system in a continuous stream, the flea, along with saliva, introduces a toxic enzyme that prevents blood clotting. After the parasite is removed, the skin at the site of the bite closes, but microbleeding underneath continues, leading to hemorrhage. Multiple bites in one place can lead to purpura (subcutaneous hemorrhage).
Frequent consequences of flea bites
- Allergy. Its options are not limited (swelling, itching, redness, anaphylactic shock).
- A severe infection of the body that the parasite suffered from other victims.
- Suppuration and inflammation of the bite.
Allergic reactions are more likely to occur in children and people whose skin is highly sensitive. If the bite is too painful or does not go away within 4 days, be sure to consult a doctor. Wounds should be washed with warm water and antiseptic soap. A piece of ice applied to the wound will help relieve swelling.
Important!
The child's body is more susceptible to the negative effects of injected toxic enzymes. The child’s immunity is weakened, so swelling after flea bites in children is much greater than in adults.
Bite areas can be treated with sulfur ointment, an aqueous solution of baking soda, vodka, iodine and brilliant green. These measures disinfect the wound, reduce swelling and reduce itching.
Do not scratch the bite site. Along with dirt, an infection can get into the wound, resulting in inflammation and suppuration.
Bites from different types of insects can cause different reactions. For example, the earthen flea does not just bite a person. It can get deep into the skin under the nails and lay eggs there, which will cause suppuration. Its larvae develop by eating purulent formations and organic tissue.
The cat flea causes fungal infections and infectious diseases, transmits helminth and cucumber tapeworm eggs into human blood. The larvae are thus spread throughout the body, affecting internal organs.
A rat flea attack is the most dangerous. A person can get sick from typhus, plague and other deadly diseases.
Important!
If you are bitten, refrain from scratching the wound. This can cause the infection to quickly spread throughout the body. If you treat the wound quickly, you will minimize the risk of infection.
Why don't fleas bite everyone?
A remarkable fact, but house fleas do not attack all people. And there is a scientific justification for such an unusual exception, which includes several judgments:
- Preference is given to people with the first blood group. Happy carriers of the fourth group are least likely to be attacked by “bloodsuckers”;
- People with thin skin are ideal victims for fleas. After all, parasites literally pierce the skin, and it is much easier to bite through thin tissue;
- The cat flea is a very aggressive and active parasite, compared to other representatives of the order. Most often, people are attacked by these parasites;
- Allergy sufferers are more sensitive to flea bites;
- A person cannot always feel bites; this can be explained by different degrees of pain threshold. Simply, some people do not notice them.
How to avoid flea bites on people?
It is possible to stop the merciless attack of fleas and escape from harmful insects by treating your home and pets. Animals must be washed with soapy water and their fur combed with a comb. You also need to apply a special anti-flea product to the fur and skin and wear an anti-flea collar. Give your home a thorough cleaning, paying attention to carpets, corners, baseboards and areas behind furniture.
To survive, fleas must constantly suck blood, so they will always be a source of infection. The bite of one insect is not dangerous, however, if the infestation continues to grow, it is very important to intervene in time and stop the epidemic!
If you do not react in time, then the likelihood of a numerous invasion of parasites is obvious. Rid your home of fleas with the help of professional exterminators and qualified technicians.
Prevent the spread of infection!
Symptoms and methods of control
Flea bites cause allergies, itching and redness. During the first hours, a blister forms, which quickly disappears. The size of the swelling depends on the type of parasite attacked. Residual effects are caused by micro hemorrhages. Their severity and duration also depend on the type of parasite.
Most often, bites occur on the legs. If the attack occurred in a dream, then the arms, neck, chest, and stomach suffer. If there were a lot of fleas, then they leave a distance of about 2 cm between the wounds. There is no consistent chain of bites, like with a bug.
How to distinguish a flea bite
- You feel a sharp pain.
- The bite site is very itchy (more itchy than a mosquito bite).
- There is slight swelling.
- More bites on the lower body and legs.
All of the above phenomena are accompanied by rashes, a possible increase in temperature, enlarged lymph nodes, and the appearance of suppuration, which indicates pulicosis.
Definition:
Pulicosis is a dermatological disease accompanied by difficulty breathing, fever, diarrhea, with signs of anaphylactic shock. You need to see a doctor immediately.
How does a flea allergy develop in humans?
When flea bites develop the so-called type 1 allergy according to Jell and Coombs. During the initial bite, the body produces antibodies specific to the flea's saliva. The antibodies then attach to the mast cells. If saliva re-enters a sensitized organism, cross-linking of the molecule in saliva with nearby antibodies occurs. This causes membrane changes and activation of cells containing histamines. In addition to histamines, other substances responsible for the allergic reaction are released - leukotrienes, prostaglandins.
Killing fleas with insecticides
Local control of insects is an ineffective method of exterminating them. First you need to find the source of the parasites. will sanitize the premises and 100% destroy all harmful insects. In our work we use certified equipment and effective chemicals that are safe for animals and humans.
If you have a pet living in your house, it also needs to be treated. You can use drops, shampoo, spray or gel. Don’t forget about the bedding (the animal’s habitat), carpets, and upholstered furniture. Thoroughly clean the room every 2 weeks, paying attention to corners and crevices. They must be treated with special means. Don't rule out car interior treatment. When killing fleas, use only professional insecticides that have already shown high effectiveness in controlling parasites. To prevent a new invasion of the premises, keep wormwood with inflorescences at home or periodically wipe all surfaces with a damp cloth soaked in tansy infusion.
Ways to control fleas
The best way to get rid of flea bites and prevent their occurrence is prevention. Simultaneously with treatment, insect extermination operations must be carried out. The entire house needs to be cleaned and sanitized. This is quite difficult, but prevention is better than subsequent treatment. After all, itching from a flea bite, swelling and redness are the mildest symptoms that may appear.
The most effective method of killing insects is treating premises with chemicals. The most effective agents are chlorpyrifos, cypermethrin and others. Before processing, it is necessary to remove all sources of heat, since the preparations are highly flammable, close all food products and remove pets from the premises, because insecticides are very toxic.
After treatment, any remaining drug should be removed. Insecticide chemicals do not reach hidden areas (such as behind furniture) or affect pets, so these products must be used in combination with other methods for maximum effect.
Contact specialists who will carry out high-quality disinfection of the premises. Only professionals will be able to finally rid the room of harmful insects by treating the room with specialized means.
Neutralization of symptoms in adults
It is recommended to select treatment with a doctor. Before using any medicine or traditional medicine, consult an allergist or therapist. The patient must be removed from the flea-infested room. He will be able to return only after thoroughly treating the home with insecticides.
The use of folk remedies
A solution of baking soda helps. To prepare it, you will need to dissolve 1 tsp in 1 glass of warm water. substances. The solution should be used to wipe the wounds at least 3 times a day.
Ice will help get rid of inflammation and swelling. Several cubes are wrapped in gauze or other thin fabric, and then the skin in the affected areas is wiped. After this procedure, the bites itch less.
Soda for inflammation.
Lotions based on green tea, calendula decoction, celandine, dandelion, parsley or plantain help. They should be done 2 times a day: in the morning and before bedtime.
Medicines to stop allergies
To relieve pain and itching, use steroid ointments Hydrocortisone or Flucinar. For other symptoms, antihistamines are prescribed. Most often, Zodak and Tavegil are prescribed from this group of drugs. To relieve itching, use ointments and gels with local action, for example Fenistil. In severe forms of the disease, Advantan, Ketotifen, Suprastin are prescribed. Aggressive medications can only be taken as prescribed by the attending physician.
Sometimes allergies are accompanied by intense pain. In such situations, you will have to take painkillers (for example, Diclofenac).
Treatment of children
Medicines used to treat adults are not suitable for children. It is necessary to select suitable medications and dosages taking into account the age and body weight of the child.
The wounds are washed and treated with an antiseptic. It is recommended to use hydrogen peroxide, brilliant green or chlorhexidine. Then they use preparations based on alcohol solutions for treatment.
The antihistamine drug Hydroxyzine is used. This drug is available from pharmacies only with a prescription. Diphenhydramine ointment for external use can also be used. This remedy helps well against allergic symptoms, but causes drowsiness in a person. Use with caution and only with a doctor's permission.
Folk remedies are also used. A compress with a mixture of honey and lemon juice will help. Apply solutions of apple cider vinegar, lotions with mint and bird cherry leaves, plantain and calendula juice. A mixture of ammonia and baking soda is also considered effective.
Treatment of the wound with Chlorhexidine.
Flea bites in a child
If parasites bite a child, the symptoms will be more severe. In addition to the manifestations characteristic of adults, there will be severe motor restlessness and excessive excitement. Children become capricious and may cry or show aggression. Characterized by stool disorders, increased body temperature, and difficulty breathing. Urticaria occurs. Sometimes symptoms of intoxication of the body are observed: a general asthenic state, weakness, lethargy, apathy, nausea, repeated vomiting.
Since children's skin is more delicate, wounds take longer to heal than those of adults. In addition, each bite causes changes in the composition of the blood.
