THERMAL FOGGING IS A WASTE OF TIME
by Marlon Ferreira
Fogging is a popular way to control mosquitoes as it is visible and creates the impression that the authorities and pest control companies are doing something to combat dengue. But in reality, thermal fogging is an ineffective method in controlling mosquitoes and it also provides a false sense of protection against mosquitoes.
Recent studies have shown that fogging is effective only when the chemicals come in direct contact with mosquitoes. At the time of fogging, mosquitoes fly away and after the smoke clears, they fly back.
Fogging is not only ineffective in controlling mosquito populations but potentially harmful to human health. Most of the chemicals used in fogging are neurotoxins that can affect the nervous system of humans, animals and birds. Frequent thermal fogging may increase mosquito resistance to insecticides, giving rise to super mosquitoes that are hard to control. Fogging impacts negatively on non-target beneficial insects such as ladybirds and pollinators such as butterflies and bees. Regular fogging operations can harm biodiversity and cause ecological imbalance.
We should also focus our attention to reset the degraded eco-system by creating an environment so that dragonflies, fish, frogs and bats will be back. They play an important role in reducing mosquito populations since they feed on mosquitoes and their larvae.
To protect the community from mosquito-borne diseases, the authorities need to look at factors contributing to a rise in dengue virus and need to focus primary on dengue prevention and implement preventive integrated mosquito management strategies to help the community to mitigate the risk from deadly dengue.
The bright side is outdoor thermal fogging is strictly restricted to private pest control companies in Sri Lanka by the regulators. It’s time for all of us to understand the realty and we must stop pretending that fogging is effective and should divert our resources to real solutions to combat mosquitoes and to mitigate the risk of dengue.
The best and safest method of mosquito control is still the elimination of mosquito breeding sites. These often involve getting homeowners and business maintenance and cleaning staff to identify and eliminate mosquito breeding sites, including less-expected breeding sites such as bracts of flowers and plants, septic tanks, gutters and damp bathroom floors. Garbage bins, recycling bins and construction waste bins filled with stagnant water create ideal breeding and harbourage sites for mosquitoes. There should be a requirement for all these bins to have drainage holes at the bottom to allow water to flow out.

Super El Niño threatens to deepen Sri Lanka’s drought and economic woes
By Ifham Nizam
A potentially dangerous El Niño is gathering strength across the Pacific, with the World Meteorological Organization (WMO) warning that the climate event is expected to become very strong and continue into February 2027, raising the risks of drought, floods, extreme heat and major disruptions to rainfall patterns worldwide.
The warning has particular significance for Sri Lanka, where communities in several agricultural districts are already facing severe drought, depleted water sources and shrinking farm incomes.
The WMO said yesterday that forecasts from its Global Producing Centres show an “exceptionally high likelihood of nearly 100%” that El Niño will persist through February next year. The organisation said this is the first time one of its El Niño/La Niña updates has been so unequivocal, reflecting strong agreement among forecasting systems.
The event, driven by exceptionally warm waters in the tropical Pacific, is expected to strengthen further in the coming months, reach very strong intensity and peak towards the end of this year. Its climate impacts, however, are expected to continue well into 2027.
According to Meteorological Organization
Sri Lanka is already experiencing the consequences.
A Reuters report published on Wednesday from drought-affected areas said rainfall deficits of between 85% and 100% have been recorded in important farming regions including Ampara and Monaragala.
Wells, tanks, rivers and lakes have dried up, while tens of thousands of people are depending on government water deliveries, with some remote communities reportedly waiting up to 23 days for supplies.
The drought is also rapidly becoming an economic problem for rural communities. Croplands have withered, livestock operations have been affected and farmers who have lost their harvests are being forced to seek daily-paid employment to survive.
The latest WMO outlook also warns that the consequences of El Niño will not necessarily be uniform. The severity and timing of impacts in individual countries depend on geography, season and other climate drivers, including conditions in the Indian and Atlantic oceans.
For Sri Lanka, the Indian Ocean Dipole (IOD) will therefore be crucial. The WMO expects a positive IOD to develop, with a September-November seasonal mean of about 0.9°C. This could modify the normal influence of El Niño on rainfall over the region.
That creates another potential risk for Sri Lanka: the country may have to prepare not only for continued drought but also for episodes of intense rainfall, flooding and landslides later in the year. Climate variability increasingly means that a prolonged water shortage can be followed by sudden and destructive rainfall rather than a gradual return to normal conditions.
For Sri Lanka, the warning should therefore be viewed as an economic and national-planning issue, not simply a meteorological forecast. Agriculture, drinking water, electricity generation, food imports, public expenditure and rural livelihoods could all be affected.
