Vietnamese entomologists are looking for more blood-sucking bugs after a group of them was found in some homes in Quy Nhon Town over the past week.
Nguyen Xuan Quang, head of the insects department at the Quy Nhon Malaria Parasite Insect Institute, said the insects have been tentatively identified as a genus of the assassin bug.
Since late August residents of the town's Hai Cang Ward have handed to the institute four bugs caught in two houses in neighborhood No. 8.
The institute sent personnel to the houses and found three mature and two young bugs.
Quang said he has urged residents to report to his institute so that they can find the insect's breeding places to spray specialized insecticides.
"People should maintain hygiene in their homes to keep out the blood-sucking bugs," he said, adding that they often live in humid places.
The bugs found in Quy Nhon Town, Binh Dinh Province belong to the same species as 27 individuals found in the Central Highlands in 2010, he said.
The bugs originated in Latin America and were first found in Vietnam 20 years ago, he said.
However, it only caused concern after a large group was found in Hanoi and provinces in the central region in 2010, he said.
Scientists initially suspected the bugs carried a parasite that causes the Chagas disease specific to Latin America.
Infected people develop chronic symptoms like digestive problems and even suffer fatal heart failure.
But the scientists later said the bugs found in Vietnam are the fairly harmless assassin bugs.
