Behind the fog of misinformation about killing Aedes misquitoes


If this article is correct the Aedes mosquito is starting to have the same level of resilience as the Terminator.

Fogging Is Not Effective Against Aedes

Fogging does not eliminate aedes mosquitoes as not all are killed in the process as some could have already moved to new breeding grounds, said Universiti Malaya Medical Centre (UMMC) vector specialist Dr. Wan Yusoff Wan Sulaiman.

He said fogging must be done at the right place at the right time; otherwise it would not bring the desired results in eliminating aedes, the primary vector for dengue and chikungunya.

“We assume where the aedes breeding grounds are when we carry out fogging but the mosquitoes may have already moved to other places. The pesticide is only effective within the radius of 200 metres,” he told Bernama.

Dr Wan Yusoff said the use of trap lamps containing carbon dioxide had also been proven ineffective to control the aedes population.

This was based on a study conducted by the Institute for Medical Research, he said.

One thought on “Behind the fog of misinformation about killing Aedes misquitoes

  1. Dear Sir,
    As a scientist working in the field of vector control for the past three decades in India and abroad, I would like to share my views towards fogging against Aedes population.
    1. Please, kindly refer to my publication on “dengue transmission” published in Environmental Health Perspectives published in February, 2009. i.e 117,(2)A56. I have highlighted the behaviour of Aedes at Jeddah, city of Saudi Arabia.
    2. I fully agree that fogging is not 100% effective against on Aedes population due to its resting behaviour.
    3. Most of the Aedes are resting at inaccessible areas where fogging could not be carried out. Most of the community may not permit the fogging operators to fog such places.
    4. The only choice of reduction in Aedes population is through Aedes breeding source reduction effectively with volunteers and other organized sectors in dengue/chikungunya endemic areas.
    5. My suggestion is that any individual above 10 years old must be trained in Aedes vector control with special emphasis on source reduction measures in the entire globe. Otherwise, the problem would be increased on many folds within near future.
    Suggestionsare welcome,
    with kind regards,
    Dr. T. Mariappan,
    Scientist, VCRC (ICMR),
    Former Advisor, Dengue crisis management and mosquito control programme of Jeddah Municipality, Kingdon of Saudi Arabia,
    Puducherry.
