Plants that will save your life

The most effective plants with mosquito bites

Feverfew (pyrethrum maiden) is a very beautiful and unpretentious plant, which insects fighters often plant around the perimeter of the back yard, as well as next to the entrance doors.

Flowers scare away absolutely all flying insects - from microscopic mosquitoes to giant dragonflies. And aversion to pyrethrum occurs at the genetic level.

By the way, this plant was actively used in medical facilities (especially in Europe of the Middle Ages). It was considered the best medicine for nervous disorders, headache and bloating.

Mites - Part three

The body covers of the tick mite are not yet fully formed - there may be no bristles, while in the shells the shell of the body is translucent and thin. Larvae are particularly active in the warm season, small terrestrial animals - mice , hedgehogs , lizards - are chosen as hosts, since it is difficult to climb these high-lying babies. On the chosen victim, the larva feeds on the blood for 3-6 days, then falls to the ground and the stage of the nymph begins. By the way, the larva perfectly tolerates flooding - under a layer of water it can perfectly exist up to a month.

According to American sources, the question whether a tick mite is dangerous for humans can be answered positively: the tick bite of a tick is dangerous if it is a larva of an encephalitis mite. Thus, the mite larva is a carrier of diseases and is dangerous to humans!

Nymph of the tick. Is the mite a nymph dangerous?

The nymph of the tick has larger sizes - from 1 to 2 millimeters, it has 4 pairs of limbs, it moves rather brightly, therefore, as a parasitic object, it can choose large wild or domestic animals, birds, and displays "aggression" to humans. Surprisingly, most of the ticks, whose life cycle is more than a year, is experiencing winter cold in the "image" of the nymph, and only with the arrival of heat, the nymph will turn into an adult of one or the other sex.

According to the US Department of Health and Human Services, 20% of nymphs are carriers of infections, for example, Lyme disease, therefore, even in spite of their not yet fully formed status, they already carry a danger. Thus, the tick nymph is dangerous to humans , and the nymph's bite can transmit various diseases (encephalitis, Lyme disease and others).

Mites - Part two

A brown dog tick is not dangerous to humans, but it is dangerous for dogs. Dwells everywhere. Particularly active in coastal areas and on the Black Sea coast.

Where do ticks live?


Ticks live in each climatic zone and on all continents. Because ticks prefer wet places, they choose forest ravines, undergrowths, thickets near the banks of streams, flooded meadows, overgrown paths, animal wool, dark warehouses with agricultural products, etc., as their habitat. Individual species are adapted for life in the seas and fresh water reservoirs. Some mites live in houses and apartments, for example, house mites, dust mites, flour mites.

Mites - Part one

Mite (Latin Acari) is one of the oldest inhabitants inhabiting our planet. Contrary to the erroneous opinion, ticks do not belong to insects, but are representatives of a detachment of arachnids.

Description of ticks. What does a tick look like?

In size, these representatives of arthropods rarely reach 3 mm, in general the size of the mites varies from 0.1 to 0.5 mm. As well as it is necessary a spider-like, at mites there are no wings. Adult mites have 4 pairs of legs, and in specimens that have not reached puberty, there are three pairs of legs. Without eyes, the mites orient themselves in space with the help of a well-developed sensory device, thanks to which they can smell the victim for 10 meters. According to the structure of the body, all kinds of ticks can be divided into leathery, with a fused head and chest, and hard (armor), in which the head to the trunk is attached movably. The supply of oxygen also depends on the structure of the body: the first breathe through the skin or the trachea, and the armor has special spiracles.
