How many degrees do bed bugs have to multiply, and how many days can bed bugs live in low temperatur

There are only two types of bedbugs that suck blood, temperate bed bugs and tropical bed bugs, and their vitality is very tenacious, and they can survive without sucking blood and will not starve to death. Only temperature can freeze them to death. When the ambient temperature drops, the bed bugs will enter a semi-dormant state, allowing them to survive longer; Even at temperatures of -10, bed bugs can survive for at least five days; However, if exposed to -32 hypothermia, they will die after 15 minutes.

The appropriate temperature for bed bugs to reproduce is generally **28-33 **relative humidity **55%-60%**

After mating in a hidden place, the adults lay their eggs in the cracks of walls, bed boards, etc. Usually one to several eggs are laid at a time, and the total number can reach 100-200. In winter, bed bugs usually stop sucking blood and laying eggs.

Nymphs can live for more than 30 days without blood food, and adults can usually live for six or seven months without blood food.

Bed bugs can starve to death without sucking blood for 1 year. Adults are very hungry tolerant, generally can withstand hunger for months, or even up to 1 year, nymphs are not as hungry as adults. Bed bugs can also suck blood during the day when they are hungry, or they can suck the blood of rats, bats, or domestic animals.

As a result, bed bugs can still survive in long-term uninhabited houses. Bed bug activity rules: Bed bugs are afraid of light and are mostly active at night.

Bed bugs are very agile and alert, and can suck the host's blood without the host noticing, and when sucking blood, if the human body moves slightly, it will stop sucking blood, crawl away and hide.

Bed bugs are not afraid of low temperatures, nor are they afraid of high temperatures, and can survive for more than 3 years in an environment of about minus 10 degrees, and can live for about 5 years if they are in a high temperature environment of about 45 degrees Celsius, and can live for about 2 years without eating or drinking. So the reason why there are so many bed bugs in Guangdong.

Right of deliberation Deliberation refers to the activities of discussing, expressing opinions, expressing wishes and positions, and affirming, rejecting, or proposing amendments to the reports and bills included in the agenda of the session. At the sessions of the people's congresses, deputies participate in the deliberation of the work reports of the Standing Committee of the National People's Congress, the courts, and the procuratorates, and examine and approve the reports on the national economic and social development plan and the implementation of the plan, as well as the report on the state budget and the implementation of the budget. In the spirit of being responsible to the people, deputies should realistically affirm the achievements of the report and motions, point out problems, and propose amendments.

2.The Right to Propose Motions The people's congresses legislating and deciding on major issues generally have to go through the procedures of submitting bills, deliberating bills, voting on bills, and promulgating laws (regulations), decisions, and resolutions. Thereinto.

1. If you find a stinky sister at home, first check whether there are gaps in the doors and windows of the house, and if there are them, seal them. It is better to put a gauze on the window to prevent it from creeping in.

2. If there are fruit trees outside the house, it is easy to attract the eldest sister, especially apple trees and jujube trees. If the tree is not big, you can shake it, and after the stinky sister falls from the tree, you can trample it to death with your feet.

The scientific name is "Tsubaki Elephant", also known as "bug", bugidae, bed bugs, there are stinky glands opening after fart, and they release stinky gas when they encounter enemies. It is widely distributed, mostly distributed in Henan, Shandong, Hebei, Anhui and other regions, especially in summer, which is a pest.

body color: black-brown; The dorsal posterior side of the head bears a pair of tiny orange-yellow, or orange-brown longitudinal spots, and the terminal of the last segment of the antennae 2 3 is partly orange-yellow or orange-brown, partly, the individual is in the first.

There is still a section of orange-yellow or orange-brown spots in the second and third segments. There is a sharp spike on the outer edge of the dorsal plate of the prothorax,** with a transverse arc orange-yellow or orange-brown fine spot.

"Bed bugs" stink, this is common sense, and it is precisely because of its stinkiness that people give it such a nickname. Once you touch the "stink bug" on your hand, it will stink incomparably, and if you kill it, the smell will last for a long time. The scientific name of "bed bug" is "Tsubaki elephant", also called "bug", and the public also calls it "bed bug", "stinky girl", etc., which is a common name for a class of more common hemipteran insects, about 30,000 species.

The "stink bomb" of the bed bug is not an offensive **, but only smoke for self-defense and defense against enemies, which is the result of long-term adaptation. As soon as it encounters an enemy attacking it, it immediately releases a foul smell to defend itself, so that the enemy will not dare to attack when it smells the foul smell, and it will take the opportunity to flee.

Bed bugs generally grow in summer and autumn, and are less likely to breed in spring and winter due to lower temperatures.

According to reports, there are 74 species of bed bugs in the world, but the vast majority are parasitic on bats and birds, and there are fewer species related to humans.

Bed bugs have a pair of stinky glands that can secrete an abnormal odorous fluid, which is used to defend against natural enemies and promote mating, and bed bugs can leave an unpleasant odor where they crawl, and in the past 10 years, bed bugs have reappeared in some developed countries and regions such as Europe, North America, Australia and Asia. It is also becoming more common in some parts of the country, and there is a risk of widespread occurrence.

Activity Rules:

Bed bugs are afraid of light and are mostly nocturnal, but they can also suck blood during the day. Bed bugs are very agile and alert, when sucking blood, if the human body moves slightly, it will stop sucking blood, crawl away and hide, bed bugs can crawl every minute. Bed bugs live in groups and can be scattered around with clothing and luggage.

Bed bugs mainly inhabit the gaps in indoor bed frames, tent corners, walls, ceilings, bedding, straw mats, mats, etc., and behind pasted wallpaper. Bed bugs often have a lot of tan droppings in their habitats.

Temperate bed bugs generally start to move in May, are more active in August, less common after October, and stop spawning and laying eggs in winter.

It will happen in any season, and it will freeze to death at minus 6 degrees, and there is no other way to disappear naturally. If you have bed bugs in your home, you can spray some medications. It's important to keep the room dry and ventilated as much as possible.

It's also good to put some insect repellent in various corners of the room. For example, we often call Blue Whiss.

Bite your blood and live a year without eating or drinking. Reproductive ability refers to cockroaches.

The reproductive ability is super strong, and the crevices are all there.

Adults are magnetic, one to three a day and soft.

High temperatures are the natural enemies of bed bugs. Bed bugs have a hard time surviving in dry and hot environments, so high temperatures can kill bed bugs. The specific temperature of how many degrees bed bugs need to be killed needs to be determined according to different bed bug species and environmental conditions.

In general, bed bugs tolerate temperatures ranging from 4 degrees Celsius to 43 degrees Celsius, but this temperature range does not completely kill bed bugs. To completely kill bed bugs, the temperature needs to be raised to more than 50 degrees Celsius for a certain amount of time, which usually lasts for a few hours or days.

Of course, environmental conditions can also affect the temperature tolerance of bed bugs. In dry or dry and ventilated environments, bed bugs are more likely to be killed by high temperatures. In addition, bed bugs can be killed more effectively if chemical insecticides or other insecticides are used in high-temperature conditions.

In conclusion, it takes a high temperature of more than 50 degrees Celsius to completely kill bed bugs. However, the use of high-temperature insecticidal methods needs to take into account issues such as environmental conditions and safety, so it may be necessary to adopt other insecticidal methods to control bed bugs. <>

The hatching period of bed bugs takes 6 to 7 days, and the eggs are oval, about 1 mm long, with egg caps, egg white, and the egg shell has a distinct reticulation pattern. It often sticks to crevices and rough surfaces.

The nymphs that have just hatched and newly molted are light brown, and later become darker, the nymphs resemble adults, and their habits are similar, but the insects are small, sexually immature and lighter in color, can suck blood, and become adults after 5 molts.

The temperate bed bug and the tropical bed bug have similar morphologies, and the main difference lies in the anterior thorax morphology: the anterior thorax of the temperate bed bug is deeply concave and the corners on both sides are wider; Tropical bed bugs have a shallow prothorax concave and narrow angles on both sides.

The life history is divided into three stages: oval, nymph and adult. The yolk is white, oblong, the shell is reticulated, and the front end is covered. After about 6 or 7 days, the nymph emerges from the bed bug egg cap, resembles an adult but is smaller, and becomes an adult after molting 5 times.

At the right temperature (35-37), it takes about 1 month for the egg to develop from the adult to the adult. In warm climates, there can be at least one generation in one year.
