1, from the outside, through the closed doors and windows, into the home.
2, indoor mosquito breeding, indoor easy to accumulate water, is an excellent spawning place for mosquitoes, usually residents of the water, balcony, flowering place, mosquito larvae can be found.
3, from the sewer into the room, the sewer is the breeding ground of mosquitoes, mosquitoes there to lay eggs, but also in the water to hatch.
To reduce the generation of mosquitoes in the home, we need to pay attention to household environmental hygiene, clean up garbage in time, and do not let the water accumulate in the home, the aquatic plants in the home, to keep the water quality in the plant clean, change the water frequently.
Mosquitoes belong to the order Diptera, the family Mosquitoes, also known as mosquitoes, and are the most important group of medical insects. Mosquitoes are widely distributed and have many species, and so far a total of 3 subfamily of mosquitoes (subfamily Macrophyllum, Subfamily Anopheles, subfamily Culex), 35 genera, more than 3600 species and subspecies have been recorded worldwide. More than 370 species have been found in China, of which more than half of the mosquito species in the three genera of Anopheles mosquitoes, Culex mosquitoes and Aedes mosquitoes.
Depending on the species, mosquito eggs may be laid on the surface of the water, at the water's edge or in three different locations in the water, such as Anopheles mosquitoes and household mosquitoes on the surface of the water, and Aedes mosquitoes on the water's edge. Anopheles mosquitoes and house mosquitoes hatch in about two days, while Aedes mosquitoes hatch in three to five days.
Female mosquitoes lay their eggs in stagnant water. The eggs are small and less than 1 mm long. Anopheles mosquito eggs are boat-shaped with floating sacs on both sides and float to the surface after being produced. Culex eggs are conical in shape, without floating sacs, and stick together to form an egg raft after spawning. Aedes eggs are generally olive-shaped, have no floating sacs, and sink to the bottom of the water individually after spawning. Mosquito eggs must be hatched in water, and in the summer the larvae usually hatch after 2 to 3 days.
