Bti is used as a larvicide to kill larvae before they can grow into adults that can bite people. Bti has been used for mosquito control for more than 30 years. During an outbreak, local government departments and mosquito control districts take the lead for large- scale mosquito control activities to quickly kill larvae that hatch from eggs.
When to use larvicide to control mosquitoes?
When community mosquito control is needed to reduce mosquito-borne disease, the Department of Health favors use of larvicide applications to the breeding source of mosquitoes. Larvicides are more effective and less toxic than adult mosquito sprays, and the applications are unlikely to result in human exposure.
Is there resistance to BTI as a larvicide?
No. There is no documented resistance to Bti as a larvicide. A recent study (Tetreau et al. 2013) confirmed previous research showing a lack of Bti resistance in mosquito populations that had been treated for decades with Bti. 6. Are there special precautions to be taken during Bti spraying?
What do you use to kill mosquito larvae?
