According to Mr. Doan Van Lu (residing in Hoai Duc commune), every day he has to go to Duc Thuong Primary School (new facility) to pick up his grandchild for lunch because his family is not confident in letting him eat and sleep at school. The classroom has too many flies, we are very scared when they stick to food.

Not only flies, some parents also reported the smell of pesticides from the wind entering the classroom. Mr. Tran Dinh Kien said that because the school is located in the middle of the rice field, flower growers often spray pesticides, causing the smell of chemicals to spread into the school, causing discomfort and affecting students' health.
According to Ms. Pham Thi Bich Lien - Vice Principal of Duc Thuong Primary School, the school's second campus will officially come into operation from the 2025 - 2026 school year. After the opening ceremony, flies appeared in large numbers. On September 9, the school reported to the Commune People's Committee and coordinated with the Hanoi CDC to determine the cause.

According to the verification results, flies originated mainly from two garbage dumps about 1km from the school in Duong Hoa commune. To overcome this, the school coordinates with the locality to spray disinfectants every month, increase hygiene inside and outside the classroom. The People's Committee of Hoai Duc commune also supported the installation of insect gates and nets, and coordinated with Duong Hoa commune to clean up and dispers the surrounding garbage collection points.
Faced with the smell of pesticides, the school has worked with Tay Tuu ward, requesting flower growers to limit spraying pesticides, especially during school hours.
According to records, the number of flies in the classroom has decreased significantly. However, some parents believe that more time is needed to assess the long-term effectiveness, especially on rainy days - the time for compensation to find shelter.
Ms. Nguyen Thi Duong, a parent of a student, said that many parents want their children to return to school at the old facility until the new facility is truly stable, ensuring full conditions for learning and living. "When the school is completed and safe, parents are ready to coordinate," Ms. Duong said.
