Barwon Heads mosquito control - what chemicals are used in your mosquito management program?

We use a range of approved products to control mosquito larvae. We do not use broad based pesticides in our aerial treatment program.

The mosquito control products used in our aerial treatments are Bacillus thuringiensis israelensis (Bti) and s-Methoprene. These products only affect mosquito larvae and do not harm people, pets and the general environment. Both products are approved by the Australian Pesticides and Veterinary Medicines Authority for mosquito management. These products target aspects of the mosquito biology and do not adversely affect humans, animals, other insects or the environment. The products have limited residual properties and do not magnify in the food chain.

Bacillus thuringiensis israelensis (Bti) produces proteins that react with cells of the gut lining of the mosquito and the infected mosquito stops feeding within hours. s-methoprene is an insect hormone analogue, which when applied to larvae, prevents the larvae from completing development to an adult. 

Depending on the larval stage and breeding location of the mosquito, a decision is made on which product to use. Up until 1987 we also used a product called Abate, which was approved for the same purpose.
