In summer, mosquitoes are infested, and the Aedes albopictus index in many regions has risen sharply.
Some experts pointed out that after days of rainy days earlier, open areas, styrofoam boxes, containers, etc. are prone to accumulation of water, which is conducive to the breeding of Aedes albopictus.
However, experts also found that many outsourced mosquito control contractors used non-professional tools, or used mosquito spray from the wrong angle, resulting in poor results. The FEHD is urged to do a good job in monitoring.
The FEHD monitors the Aedes albopictus trap index in various districts, and some districts have seen a sharp rise in the past month, with Sheung Shui and So Kwun Wat in Tuen Mun being the worst.

The FEHD monitors the trapping index of Aedes albopictus in various districts. Among them, Ma On Shan reached 42.5% last month, which means that Aedes albopictus, which can transmit dengue fever, is widely distributed.
Shatin District Councillor (On Tai) Cheng Chung-hang said that many residents have reported that the waterfront promenade and low-rise units are prone to mosquitoes. Taking Ma On Shan as an example, the coastal areas are managed by the LCSD, the streets and public areas are managed by the FEHD, and the housing The gardens are managed by themselves, and they are independent of each other, which hinders the effectiveness of mosquito control.
He believes that the FEHD has made great efforts to eliminate mosquitoes, including the introduction of "mosquito traps" to sterilize mosquitoes and reduce the fertility rate of the population, as well as the use of mosquito-killing robots, but they are only placed in their own jurisdiction and lack coordination. The Department will coordinate and monitor managers in different areas to check whether the mosquito control efforts are sufficient.
Liang Guangyuan said that there is a lot of room for improvement in the current mosquito control work.

Leung Kwong Yuen, president of the Hong Kong Pest Control Practitioners Association, said on the same program that on rainy days, open spaces, styrofoam boxes, containers, etc. tend to accumulate water, which is conducive to the breeding of Aedes albopictus. If government or industry supervision is not in place, adults are prone to appear. Then lay eggs, causing mosquito infestation.
He said that there is a lot of room for improvement in the current mosquito control work. From the TV clips, it is found that many outsourced mosquito control work is unprofessional. For example, professional-grade ULV wireless mosquito control sprayers have not been used to kill adult mosquitoes; However, when spraying the anti-mosquito spray, it should be sprayed directly or at an angle to the ground. "The mosquitoes will fly high before the potion is buried." He explained that it should be sprayed at a 45-degree angle to effectively kill mosquitoes.
He believes that the FEHD should do a good job of monitoring and seize the prime time to kill mosquitoes, that is, the peak infestation period within two hours after sunrise and two hours before sunset, otherwise the mosquito control work will be inferior.
