Will there be more mosquitoes in the house after the rain?

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.

1. Rainy days.

There will be mosquitoes, but there may be fewer mosquitoes on rainy days. Mosquitoes mainly rely on the heat of the body to sense the things around them, and when the temperature of the rain decreases, they cannot sense the things around them normally, and the mosquitoes at this time will generally hide in dark corners.

2. Mosquitoes belong to the order Diptera.

The mosquito family, also known as "mosquitoes", is the most important group of medical insects. Mosquitoes are widely distributed and have many species, and so far there have been 3 subfamilies (Macropheles subfamily, Anopheles subfamily, Culex subfamily), 35 genera, and more than 3,600 species and subspecies of mosquitoes recorded in the world. More than 370 species have been found in China, including Anopheles mosquitoes, Culex mosquitoes and Aedes mosquitoes.

More than half of the mosquito species are in the three genera.

There are mosquitoes on rainy days. On rainy days, the air humidity is high and the light is weak, and the substances secreted by human beings cannot be quickly volatilized due to the stuffiness, and these substances have a trapping effect on mosquitoes. Therefore, mosquitoes are especially abundant on rainy and sultry days.

In addition, mosquitoes also like to move in shady, damp places, so they can also come out on rainy days. <

There are mosquitoes on rainy days. In hot or rainy days, the air humidity is high, the light is weak, and the substances secreted by people cannot be quickly volatilized due to the stuffiness, and these substances have a trapping effect on mosquitoes. Therefore, mosquitoes are especially abundant on rainy and sultry days.

In addition, mosquitoes also like to move in shady, damp places, so they can also come out on rainy days.

As the case may be. If mosquitoes are at the door or window before it rains, open the door and window at this time, and the mosquitoes will come in. In general, most mosquitoes will take refuge under trees or other safe environments before heavy rain comes.

It doesn't matter if you get hit by a raindrop, the mosquito is covered with hydrophobic hairs. As the mosquito falls at the same time as the raindrops, the hydrophobic surface remains separated from the raindrops. By turning their abdomen, mosquitoes can easily get rid of the effects of raindrops.

Overwintering is a physiological adaptation of mosquitoes to seasonal changes in climate. The regular physiological state of the mosquito itself is inhibited and enters a dormant or diapause state. Female mosquitoes overwintering with adult mosquitoes do not suck blood, the ovaries stop developing, the fat body increases, and they hide in dark, warm, humid and unventilated places such as caves, cellars, wall cracks, greenhouses, basements, etc., do not eat or move, and their metabolism drops to the lowest point; By the warm spring of the following year, mosquitoes begin to revive and fly out to suck blood and lay eggs.

Adult mosquitoes overwintering include Culex tire, Culex pale color, Anopheles sinensis, etc.; It is more common in Aedes mosquitoes that overwinter with eggs, and Anopheles hominus mosquitoes can also overwinter with eggs; Mosquito species that overwinter with larvae are more common in clean water bodies, such as Anopheles parvum and larvae that harass Aedes mosquitoes.

Mosquitoes are particularly abundant on hot and rainy days, 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 can act as a "scent language" for warm, moist smells, exhaled carbon dioxide, volatile sweat, and other secretions.

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.

This state of affairs should not be possible. "Although mosquitoes live in water during the egg, larval and pupal stages, this cycle takes about 10 days. "Under normal circumstances, water in residents' homes is not stored for 10 days.

Generally speaking, blood-sucking mosquitoes are mainly female mosquitoes, and its survival cycle is about one month, "mosquitoes are more sensitive to carbon dioxide, and some people have a fast metabolism and a high concentration of exhaled carbon dioxide, which will attract mosquitoes." For example, pregnant women, children, or people who are relatively obese fall into this category. ”

All blood-sucking mosquitoes are female mosquitoes, female mosquitoes need to suck blood in order to raise the eggs in the hatching body, and the mosquito's spawning place is in the water, before the rain, the mosquito can feel the arrival of the rain in advance, and will suck blood frantically before the rain, and hatch the eggs in the body as soon as possible, so as to lay eggs in the puddle after the rain.

Most of the mosquitoes that appear at this time are midges, and it is now the breeding season of midges. However, due to the low temperature, the adults will die quickly after mating, and the number is expected to decrease significantly within half a month. Mosquitoes feed on plant sap and do not suck human blood, and mosquitoes living in water may carry bacteria, and water pollution is also a problem, so it is best not to shoot them with their hands.

Because the environment is suitable for the growth of mosquitoes

Because mosquitoes have more eggs and more mature.

Mosquitoes are all water mosquitoes and love water.

Because of the rain, mosquitoes have to hide at home.

In humid conditions, mosquitoes tend to come out and move.

Mosquitoes can feel the arrival of rain in advance.

Because mosquitoes like to lay their eggs in clean water, such as small river water, rain puddles, ponds, ponds, rice paddies and mountain streams. Mosquitoes will intensify their egg-laying after rain.

Depending on the species, mosquito eggs may be laid on the surface, near the water, or in three different locations: Anopheles mosquitoes and house mosquitoes on the water surface, and Aedes mosquitoes at the water's edge.
