“It’s the best choice on the market of biological technology for the control of larvae, due to its 10 week residual effect, which even allows replacing 80% of daily water without losing the effect,” said Ministry of Health program manager, Rodrigo Marin, in a press release.

Spinosad bacteria can also be used in large amounts of water in gardens, ditches, pipes, ponds, pools, fountains, batteries, containers, among others.

The Ministry of Health recommends the use to municipalities, individuals with large properties, hotels, schools and industry in general.
