Probably yes. There is no evidence to prove the safety of the use of larvicides in drinking water. However, there are few studies evaluating the effect on the population of mammals, as are the bioavailabilities and cytotoxicity reviews show that in low concentrations are safe and no genotoxic or carcinogenic effects. Larvicides evaluated and authorized for use in drinking water by the World Health Organization, intended for human consumption are: DIFLUBENZUROM, METOPRENO, NOVALUROM, Pirimifós/, PIRIPROXIFEM, ESPINOSADE, TEMEFÓS, beyond Bacillus thuringiensis israelensis (BTI). It is recommended to always use the correct dose of larvicides. Temephos is used to treat outbreaks, but should not be used in fish tanks. Approved for use in drinking water. The pyriproxyfen is an ether and there is no evidence to support that it causes damage in mammalian fetuses. BTI are recommended as larvicides for use in public health, it is a bacterium that contact with water releases toxic to the larvae of some insects. The application should be performed by trained professional. BTI has no acceptable daily intake, however the guidance of use should be 1-5mg/liter. The evaluation of chemicals of any kind should always stress the possibility of bioaccumulation. Substances that are not biodegraded are biopersistent and remain at high levels in the tissues of living things. So even if the substances are not for direct human consumption, an appraisal of its use in agriculture, river bed and pastures should be carefully evaluated.
