No spray solution for insect swarming
Berri Barmera Council 30 Mar 2015

The insects in Cobdogla have been identified as a type of Chironomidae, a non biting midge. There is no risk of disease transmission, although it is acknowledged that the persistent nature of the insects is a concern for residents and businesses. Council has yet to be advised of any suitable treatment options and will not spray these insects as the chemicals are non-selective and would have significant impact on ecosystems.

Council is hoping that the sub species will be further identified, however, this can be difficult and may not assist us any further.

Council has been advised that the adult insects live for only a few days. It is likely that this type of event could happen regularly. Possibly every year, 5, 10 or 20 years, whenever the conditions are favourable. The insects will remain around while conditions are favourable.

Council has yet to be advised of any possible treatment options and it is unlikely there is an option. We would not spray these insects for the same reasons we do not spray mosquitoes - the chemicals are non-selective and would have significant impact on ecosystems. Other chemicals investigated would also have significant impact on ecosystems.

The insect have also been present in Barmera and Monash, however they are patchy and are not found throughout the whole township as is the case in Cobdogla. Businesses in the effected areas are doing their best to manage this situation.
