Why are there so many mosquitoes in rural rooms on rainy days?

The weather is hot and rainy days.

There are a lot of mosquitoes, which is related to the habits of mosquitoes. Mosquitoes and other insects have chemotaxis, that is, they have a certain tendency and avoidance response to certain special odor chemicals. In addition, mosquitoes also prefer to move in dark, damp places.

With its antennae in its eyes and head, as well as sensitive sensors on its three pairs of feet, it responds to warm, moist odors and exhaled carbon dioxide from the human body.

The smell of sweat and other secretions can be received as a "smell language".

In hot or rainy weather, the humidity in the air is high, the light is weak, and the substances secreted by people can not be quickly volatilized due to the stuffiness. Therefore, on rainy days and when the weather is hot, people feel that mosquitoes are especially abundant.

There are usually a lot of mosquitoes before the rain, because mosquitoes can sense the arrival of the rainy day in advance, suck blood frantically before the rain, and hatch the eggs in the body as soon as possible in order to lay eggs in the puddle after the rain. Therefore, not only will the rain not destroy mosquitoes, but mosquitoes will also multiply with the help of rainwater, so it is no wonder that mosquitoes have not become extinct since their emergence in the Cretaceous period.

How do you fight back against these pesky mosquitoes?

1. Soil method to kill mosquitoes.

Place the cool oil and wind oil essence with the lid open indoors; Mosquito repellent grass is planted in the house; Put an empty wine bottle with sugar water or beer in a dark place, mosquitoes will drill into the bottle when they smell the sweet wine, and they will stick to the sugar water or beer to death; Eat raw garlic and take vitamin B orally

2. Chemical mosquito repellent.

Mosquito coils, as early as the Southern Song Dynasty, there were mosquito repellent sticks made of traditional Chinese medicine, and now there are mosquito coil tablets, mosquito coil liquid, electric mosquito coils, etc., the active ingredient in mosquito coils is pyrethroid, which has the effect of repelling mosquitoes.

3. Physical mosquito control.

Indoor mosquito nets for mosquito prevention; Mosquito killer lamps can be used outdoors, the ultraviolet light of mosquito killer lamps is attractive to mosquitoes, and the lamp tube is used to trap mosquitoes to touch the net, and then electrocute the mosquitoes.

Rainy dayThere are more mosquitoes. Because mosquitoes can sense the arrival of rain in advance, and their spawning grounds are carried out in the water, they will come out to absorb blood on rainy days. Most of the blood-sucking mosquitoes are female mosquitoes, which will come out to suck blood frantically before the rain, so as to hatch the eggs in the body, so that they can lay eggs in the rain, so that they can reproduce more.

In addition, mosquitoes are mostly water mosquitoes, and of course they prefer rainy days.

Generally speaking, mosquitoes like to inhabit in hidden, dark and poorly ventilated places, such as under the bed, behind the cabinet, behind the door, in the wall cracks, livestock houses, basements, etc., and outdoors in the grass, caves, cellars, bridge holes, stone crevices, etc.

Habits

Male mosquitoes have filamentous antennae with ring hairs, and are generally denser than female mosquitoes. Male mosquitoes feed on nectar and plant sap, and females sometimes eat as well, but most eggs only mature after sucking blood once. Different mosquito species have different host preferences, but there are no strict restrictions in many cases.

The eggs are laid on the surface of the water and hatch into aquatic larvae (孑孓). The larvae swim in rapid writhing motions and eat algae.

and organic detritus, a few carnivorous, and even eat other mosquitoes.

Unlike most insects, pupae are mobile and breathe through a snorkel on their chest. Adult mosquitoes mate as soon as they emerge from their pupal shells. Lifespan varies greatly depending on the species. Mosquitoes appear to be hosts of moisture, lactic acid, and carbon dioxide.

Attracted by body heat and exercise.

Mosquitoes seem to find their host by their sense of smell. The mosquito call is caused by the rapid flapping of the wings; Females fan less frequently, so they can be identified by males. Reproductive habits are diverse.

Controls include eliminating breeding sites, spraying oil over water to block the snorkels, and killing the babies with pesticides. Adult mosquitoes can be eliminated indoors with synthetic organic insecticides.

There will be fewer mosquitoes on rainy days, but when it is particularly cloudy before the rain, there will be a lot of insects, and when it rains, the mosquitoes are already hiding, and there is no way for them to fly out, so we will rarely see mosquitoes on rainy days.

1.Mosquitoes rely on the heat of their bodies to sense things around them, and when the temperature drops when it rains, they can't sense it properly, so they can't fly. 2.

When it rains, the water vapor in the air increases, and it cannot fly normally with small droplets of water on its wings. 3.When it rains, it is not that there are no mosquitoes, but that they hide in a dark place and do not come out.

Mosquitoes are especially abundant on rainy days in summer, mainly because the reproduction and growth of mosquitoes are related to climatic conditions such as temperature and humidity. In hot and humid environments, mosquitoes hatch and grow faster, and rainwater can provide breeding sites, such as waterlogged potholes and roadside water-damaged ditches.

Therefore, the high temperature and humidity on rainy days in summer are very beneficial for mosquito breeding, and the number of mosquitoes increases accordingly.

In addition, rainy days also allow people to take shelter indoors, and the temperature and humidity in the room are also suitable for mosquitoes to grow and breed. Therefore, on rainy days in summer, it is easy to breed and rampant mosquitoes.

In order to prevent mosquitoes from biting people and spreading diseases, you should pay attention to cleaning up the surrounding environment, avoid water accumulation in puddles, ditches and other places, and use mosquito coils, mosquito nets and other measures to prevent mosquito bites, I hope mine is helpful to you, thank you!
