All types of insects attack and prey upon human beings. Most typical of those who attack the body directly are the lice and also the itch mites. Less frequent are bedbugs and spiders. In the woods and in tropical areas chiggers and mosquitoes, ticks and the biting flies annoy mankind.
Chiggers
Chiggers are known scientifically as Trombicula irritans. They hook themselves on to the skin. The skin becomes irritated, and an intolerable itching begins. Red blotches appear, and blisters form. The chiggers do not burrow into the skin, however they inject a substance that dissolves and softens the tissue, and this causes the itching.

Lice
The louse is an annoying inhabitant on the human body. Head lice are such a frequent annoyance among children in faculties that health departments sometimes provide special instructions for their control. Several specialised mixtures have been developed for getting rid of head lice, body lice, and pubic lice.
To kill head lice, ordinary crude petroleum or kerosene mixed with sweet oil or olive oil, half and 0.5, is rubbed well into the scalp. Then cover the hair with a bit of muslin for a minimum of two hours or, higher, overnight. Petroleum is poisonous and inflammable. Never let the hair get close to any open flame, such as a gas jet or a lighted match. When the muslin is removed wash the hair and scalp with soap and hot water and rinse well with clear water. Repeat this process so long as live vermin are found within the hair. Nits might be removed by wetting the hair thoroughly with hot vinegar, then combing with a fine-toothed comb. Dry the hair fully once such treatments before going out. For body lice, the body, all clothing, and all bedding might be completely dusted with a suitable DDT powder.
Pubic lice are commonly referred to as “crabs.” Specialised ointments together with the old-fashioned “blue ointment” and “Gammexane” ointment, are used, rubbed completely into the infested areas. If such lice get into the eyelashes, they should be picked off, with their nits, by a forceps. Itching from the bites of lice or alternative insects is controllable by ointments or lotions containing little amounts of phenol or menthol or camphor, like 1 per cent phenol or menthol in calamine lotion or phenolated camphor in mineral oil.
Spider Bites
The only venomous spider within the Western Hemisphere is the black widow. When a person is bitten by a spider the primary step is to prevent the absorption of the poison into the circulation. The wound will be disinfected with tincture of iodine or any alternative sensible antiseptic. If any considerable amount of poison has been taken into the body, the area of the bite can be put underneath suction.
Following the bite of the black widow spider, one feels a pointy pain. Then comes swelling and redness at the bitten spot, and the entire body reacts with dizziness and weakness, tremor of the legs, and even abdominal cramps. Small youngsters may have difficulty in respiration and even stupor or convulsions. A serum or antitoxin has been developed, however must be secured in most cases from the health department or directly from the manufacturer.
Bedbugs And Fleas
A bedbug bite typically seems as a raised blister with a red spot in the center. It itches and generally has a burning sensation. Bedbugs do not continue to exist the human body however they do infest beds, bedding, upholstered furniture, walls, woodwork, and draperies.

As a result of the bedbug bite itches, the bitten space could be masked by the results of scratching and secondary infection. People who wear pajamas, if bitten, are sometimes affected in the areas around the ankles, the wrists, and therefore the neck. The only treatment usually required for a bedbug bite is application of a lotion of calamine, with menthol or phenol or camphor to relieve the itching. Any of the lotions typically used for itching could be applied to flea bites.
Fleas that infest rodents can carry diseases like plague. Fleas are found everywhere. They’ll pass to personalities from dogs, rats, or pigs. When groups of people are bitten by fleas the supply of infestation should be found and eliminated. Flea powders are easily accessible at any drug store.

The itch mite will not have the identical habits because the body louse. The body louse lives in the clothing and feeds on the body, but the itch mite lives in the body underneath the skin. Any infestation of clothing or bedding by the itch mite is accidental. The itch mite tunnels below the skin. If the skin is cleaned and is free from crusting and secondary infection the miscroscopic spots of invasion can be seen. The feminine mite burrows into the skin through the hair follicles and travels along a tunnel, which she creates. At the inner finish of the tunnel she lays her eggs. When three to five days the eggs hatch, and also the larvae burrow along new tunnels or come back out of the recent one.

Then he’s given another painting with the benzyl benzoate emulsion. Once a second 24-hour period he’s instructed to bathe and put on all clean clothing. If these instructions are carried out carefully ninety five per cent of patients are cured. The failures are given another course of treatment. The ointment referred to as Gammexane, which is exachlorocyclohexane is also used effectively against scabies. The new treatments tend to interchange the older use of sulphur ointment, pyrethrum ointment, and rotenone ointment.
Mosquito Bites
The mosquito is proof of Kipling’s famous statement that “the feminine of the species is additional deadly than the male.” The male mosquito will not bite. The feminine mosquito is out for blood. The mosquito does not really bite, but saws through the skin.

The itching of the mosquito bite will be controlled by the employment of 1 per cent menthol or phenol in calamine lotion or by the application of the ointments of antihistamines like neohetramine, neoantergan, thephorin, pyrabenzarnine, benadryl, diatrin, and others.
