Preventing insect - borne diseases Pests
All kinds of insects and prey to attack humans. The most common of those who attack the body are the lice and itch mites. Less frequent are the bugs and spiders. In the woods and in the tropics chiggers and mosquitoes, ticks and biting flies annoy mankind.
Chiggers
Chiggers are the scientific name is irritans Trombicula. They plug into the skin. The skin is irritated, and itchy intolerable begins. red spots appear and form vesicles. The chiggers do not burrow into the skin, they inject a substance that dissolves and softens the tissues, causing itching.
Infestation by chiggers can be avoided by putting the flour powdered sulfur or bottom or underwear when going into high grass or weeds. Protection can be done by wearing leggings and shutting down the trousers.
If you have been seriously bitten by chiggers and wash skin thoroughly with soap and water and allow foam to remain on ten minutes before removing the skin. Then, no anti-itch preparations can be applied to keep the itching under control until healing.
Repellents such as DDT, freon with pyrethrum, and similar preparations may be used to eliminate chigger infested areas, as well as mosquitoes, moths and other insects.
Lice
The head louse is a troublesome on the human body. Head lice are a nuisance as common among children in schools and ministries of health in general to give specific instructions for their control. Several specialized mixtures have been developed to get rid of head lice, body lice and pubic lice.
To kill head lice, regular, crude oil or kerosene mixed with sweet oil or olive oil, half-half, rubbed well into the scalp. Then cover hair with a piece of muslin for at least two hours, or preferably overnight. The oil is toxic and flammable. Never let the hair closer to naked flames, like a jet of gas or a match. When the muslin is removed wash the hair and scalp with soap and warm water and rinse with clear water. Repeat this process as long as live lice are detected in the hair. Nits can be removed by wetting the hair thoroughly with hot vinegar, then combed with a fine tooth comb. Dry the hair completely after this treatment before going out. For body lice, body, clothes and sheets can be carefully dusted with DDT powder appropriate.
Pubic lice are commonly called "crabs". specialized ointments, including the old "blue ointment" and "Gammexane" ointment, are used, rubbed thoroughly into the infested areas. If lice come in such eyelashes, they must be picked up, with their slow by a forceps. The itching caused by bites of lice or other insects can be controlled with ointments or lotions containing small amounts of phenol or menthol or camphor, such as 1 per cent phenol or menthol in calamine lotion or camphor phenol in mineral oil.
Spider bites
The spider venom in the Western Hemisphere is the black widow. When a person is bitten by a spider the first step is to stop the absorption of the poison into the circulation. The wound can be disinfected with tincture of iodine or other antiseptic. If a considerable amount of poison has been taken into the body, the area of the bite can be evacuated.
Following the bite of black widow spider, you feel a sharp pain. Then came the swelling and redness at the bite site, and the body reacts to dizziness and weakness, tremors, legs, and even cramps. Small children may have difficulty breathing and even stupor or seizures. A serum or serum has been developed, but must be assured in most cases, health.
