There are reports that "I saw a red tick", but it is probably a different type from the house dust mite (dust mite) often found on indoor carpets and sofas. This is because dust mites cannot be confirmed with the naked eye, and their body color is often milky. This time, we will introduce the ecology and characteristics of three types of insects, sometimes called "red mites".
How is it different from a tick?
How to distinguish Takara ticks, ticks, and tsutsugamushi.
All three types of insects Mites Is a companion. It is easy to multiply indoors such as futons and sofas and has a size that cannot be seen with the naked eye. Dermatophagoides mite Unlike, it basically lives outdoors. It mainly occurs from early summer to autumn, and can be visually confirmed without using a microscope or loupe.

(Body length about 0.2-0.4mm)
The thing that moves around quickly is Takara tick . There are many opinions that the movement is unpleasant, but there is practically no harm to humans. There have been no reports of Takara tick stabbing humans, and it is the least dangerous of the three species. However, there are many people who want to prevent and exterminate.

(Approximately 1 to 2.7mm long)
What ’s bigger than the other two Tick . It is a large class in the order of mites. The body color is brown, close to red. When stabbed, Severe febrile thrombocytopenia syndrome (SFTS) Dangerous insects that can also develop. Please do not touch it even if you see it.

(About 3mm long)
Scrub beetle There are also various body colors, but red beetle is beautiful red. There is constriction and the body is sharp. Some poisonous chiggers have the pathogen "Rickettsia tsutsugamushi", so be careful when you go to the wilderness of the habitat! Please go out with clothes that do not expose your skin.

(Body length about 1mm)
First, we introduced the points that can be distinguished based on appearance and movement. Then focus on each type and learn more.
TAKARA ticks with many mysterious parts.
Mysterious queen in the insect world?
In the past, children caught a cicada body with a red tick like a beautiful treasure Takara tick There is a legend that it came to be called. The theory also suggests that the TAKARA ticks have a beautiful red color, which makes them look like insect accessories. There are various theories, and such places are also mysterious.

Although slightly different depending on the species, the larvae of the mites are parasitized by semi-grasshoppers, longhorn beetles, spiders, etc., and ingest nutrients by sucking their body fluids. On the other hand, adults are omnivorous because they eat moss on the wall and prey on spider mites and scales on the leaves and stems of plants.

The TAKARA ticks that have been found so far are ... all female! No males have been found yet. A mysterious insect that inherits only the female gene and repeats parthenogenesis. There are many parts of its ecology that have not been clarified, and it is shrouded in mystery. The mysterious name “Mysterious Queen” is probably not wrong.

A typical species commonly found in Japan is the Kabeanatakaramite. It is often found on walls, etc., but the name "ana" in the name is said to have a hole called "urnula" behind the eyes, not the "hole" in the wall hole .
The peak of the occurrence of Kaveyana tick is from April to June. Even in the midsummer, you can often see them crawling on the wall of the block wall or on the concrete, but the feature is that the small body is resistant to heat. Kaveyanata mites feed on pollen, small insects, lichens, etc., and have a wide diet. If you find red ticks that are eating pollen while gardening, you may be more likely to have a cabbage.
Speaking of gluttons are ticks.
Amazing constitution that is many times larger than your body.
Larvae and nymphs feed on humans and animals for growth, and adults for spawning. Depending on the type, for example, in the case of Haemaphysalis longicornis, the female (female) length before sucking blood is about 3-4 mm. After sucking blood ... 3-4 times larger! It is a phenomenal constitution that grows little by little and eventually becomes over 1cm in size. After a few days, it will swell like a balloon.

(About 3mm)

(About 10mm)
In addition to Haemaphysalis ticks, there are a variety of species, including Yamatic ticks, Tanegata ticks, and Schulze ticks. There is also a tick named Takasago Kiraramadani (Takasago Kirara Shinshin), a representative of the glittering name of the pest world.
In many cases, the ticks do not cause pain even if they are sucked by ticks. I understand you want to get rid of it quickly, but wait. It is dangerous to exterminate blood-sucking ticks while they remain on the skin, as ticks may remain in the skin. We recommend that you go to a medical institution as soon as possible in order not to reverse the pathogens in the body of the tick.

Ticks begin to increase from March to April, and the full-fledged period is from October to November. It is one of the insects to pay special attention to when hiking or camping in autumn. It is forbidden to be careless throughout the year because there are species that live in winter. It is easy to parasitize mammals such as dogs, so be sure to check it when you return from a pet walk.

Scrub beetles, both non-toxic and toxic.
I thought it was a cold, but maybe ...?
Scrub beetle Is written in kanji, "tsutsugamushi". "Tsutsuga" has the meaning of "sickness" or "disaster", and even now, greetings such as "Would you like to spend your time without notice?" There are various theories about the origin, and there is a theory that when traveling to a region where tsutsugamushi disease was widespread, the word "travel without tsutsugu (without tsutsugi)" was born. Tsutsugamushi disease Some say that it was because of the fashion. There is no doubt that scrub beetles can cause disaster, but not all of them are toxic.
The tsutsugamushi larva has three pairs, and the adult has four pairs. Adults are about 1 mm long and can be seen with the naked eye, but larvae are about 0.2 mm and are difficult to see with the naked eye. Also Tick It does not absorb blood like, and does not swell after adsorption. Scrub beetles adsorb to absorb body fluids, not blood, and only stab larvae. It is infested by rats, birds, reptiles, etc., but sometimes stings humans ... It is known that it reacts and absorbs carbon dioxide emitted.

(About 0.2mm)

(About 1mm)
Symptoms vary depending on the type. It may not be painful or itchy, but for example, it may be itchy in a scab beetle, or it may last for a week or two in a pinch beetle. Being bitten by the toxic tsutsugamushi, which has the tsutsugamushi disease rickettsiae pathogen of tsutsugamushi disease, can cause pneumonia and cerebral inflammatory conditions, and in the worst case can lead to death, which is very dangerous.
Takara tick And Tick Tsutsugamushi which is hard to find when compared with. Care should be taken especially when larvae occur. The major outbreaks occur in summer for red mites, and for spring and autumn in mites. When going to wilderness or rivers where the habitat is located, wear long sleeves and long pants and use insect repellent (pesticide) before going out so that the skin is not exposed.
