Do bugs suffer infection?

For a long time it was believed that bed bugs are dangerous for humans because they can to carry the infection. However, after a series of studies, scientists found that there are pathogenic bacteria on the body of the insects and in their litter, such as:

• relapsing typhus;
• tularemia;
• tuberculosis;
• yellow fever;
• syphilis;
• Hepatitis B;
• HIV

However, all these bacteria are processed in the body of the pest and cannot be transmitted through blood to humans. The only way of infection is through the contact of a human hand and litter bugs, but this probability is negligible.

Other species of bedbugs

Considering the question of what is wrong for human bugs, it is necessary to tell about other species of bedbugsthat live in nature are aquatic and herbal species.

Water species

Water bug

The bugs of middle and northern latitudes living in stagnant or calm water come in several varieties:

• Giant water bug (smooth) - refers to predators and reaches 1-1.5 cm in size, swims in the water with its belly up, and with its eyes located on its back it looks to itself for prey at the bottom of the reservoir. Their distinctive feature is an air bubble, which hangs at the end of the abdomen. This air he breathes. Such insects can bring harm to humans by stinging it, for which they received the nickname “water wasp”. Water bugs able to fly through the air from one reservoir to another and therefore widespread.
• Water striders - Frequently encountered inhabitants of reservoirs, puddles and even the seas, are safe for humans.
• Rowers - also live in water, but swim back up, size up to 16 mm. With the help of the front paws with tubercles are able to chatter. They have no proboscis, but they eat by mouth, helping themselves with their forelimbs. They can fly, starting straight from the water.

On a note!

Of the three species into which water bugs are subdivided, only smooths are a danger to humans. But they can bite only in case of danger, so it is not recommended to touch them.

But in the southern and tropical countries of Asia and America are found huge bugs belostoma up to 10 cm in size, which the locals call "alligator mites". They feed on tadpoles, small fish and fry, injecting a poisonous substance into the bite site that acts paralyzingly. After which the parasite sucks all substances from the body of prey. For humans, such predators do not pose a threat.

Herbal species

Grass bugs They live in forests, gardens, in the fields and gardens, feed on vegetable sap. The question of whether a grass bug is dangerous to humans seems strange because they harm only plants.It is small, only 7 mm, bright green or brown-black in color with a yellow head and protruding red eyes.

The grassy insect species is dangerous not for the person himself, but for the garden crops planted by him, and he eats everything - leaves on trees, grass, flowers, berries and vegetables. With its strong reproduction can occur massive death of plants in the garden.

Triatom bug

Triatom bug

The most dangerous species is the American triatom bug, visually very similar to the bed. The danger of this type of bug bite is that it suffers a deadly disease - Chagas disease, in which the parasite trypanosome penetrates human blood.

With its active reproduction, there is a strong intoxication of the human body: fever, swelling and death. For his fatal bite in his homeland, he was called a kiss, bug killer. The number of victims has already reached 300 thousand people.

As follows from the above, only some species of bedbugs are harmful to humans, mostly living in nature in distant countries, and not in an apartment.Most species can only deliver temporary minor troubles.
