Because mosquitoes prefer to lay their eggs in containers with water and actually don't like ponds or puddles, Lien has suggested that farmers place some water plants--such as water hyacinth--in the barrels to create the "illusion" of a pond ecology. In addition, farmers could put guppies or other larvae-eating fish into the barrels, and there would even be no harm in adding a small amount of insecticide to the water.
由於斑蚊偏好的產卵地是積水容器，一般的池塘反而不愛，因此連日清也建議農家在容器中種些水生植物如布袋蓮等，「偽裝」成池塘生態，甚至在裡面養些專吃孑孓的大肚魚、孔雀魚，或不妨在水中加進一點殺蟲藥。
