There are recent effective and affordable alternatives to RIDL in controlling mosquitoes that spread dengue fever and other diseases. Extracts from the paradise tree Melia azedarach showed promising larvicide and oviposition deterrent effects on the mosquito. Essential oil from mullila and zedoary plants also proved effective in treating mosquito larvae. Euphoriaceae extracts, particularly Euphorbia tirucalli can be applied as an ideal larvicide against Aedes aegypti.
A study in Thailand surveyed water-filled containers where Aedes mosquitoe pupae were found. Large water containers held 90 percent of pupae in rural areas and 60 percent in urban areas. Covering and treating such large containers should greatly reduce the mosquito population. Bacillus thuringiensis israelensis VectoBac proved effective in treating water jars to combat dengue mosquitoes in Cambodia. In Cuba, studies on the social and environmental determinants of Aedes aegypti confirmed that the greatest risks were associated with failure to treat stored water, and water in flower vases for religious practices. Efforts to reduce infestation should therefore focus on preventive practices.
These low tech practices may prove much more effective than the expensive high technology solutions, which are also far from safe.
It is said prevention is better than cure,it should therfore be first in our minds to cover all sources of water, and also to treat the containers, and do ourselves a small favour by covering up in the evening,the mosquitos meal time,if we do not want to be on the menu, long sleeved shirts and long trousers will help
