Mosquito Control

Frequently Asked Questions

What chemical is being applied?

We will be using Garrards Pyretherin Drift, if you would like more information on the product please contact the Shire of Exmouth's Health Services or see the following links:

Gerrards Pyrethrin Drift Insecticide SDS and label.

How is the chemical applied?

A licensed pest control operator will be driving a vehicle mounted fogger slowly down each of the streets listed.

Is the product safe?

Pyrethrins are very toxic to fish and other aquatic organisms, however they have little residual activity and breakdown rapidly upon exposure to sunlight. All chemicals carry a risk with them, but used correctly and to label requirements this risk is reduced. If you don't want the vehicle to fog outside your property please contact the Shire of Exmouth Health Services 9949 3000, 0429 881 918 or

Do I need to bring my pets inside?

As a precaution where possible keep animals in an enclosed area or towards the rear of the property, but they shouldn't experience any concerns if they come into contact with the drift. Cover any fish ponds with a tarp or something similar while the fogging is occurring.

Can I eat fruit/ vegetables from my trees or garden after the fogging?

The chemical used is a non residual chemical, but if you do collect fruit or vegetables from your garden the night of the treatment wash them prior to eating them as a precaution.

Do I need to close windows or turn off the air conditioner?

It is advisable to close windows and turn off the airconditioner while the drift is present.

What is the current status of mosquito borne virus?

There has been no notifications received by the Shire for Ross River virus or Barmah Forest virus. There also has been no detection of Murray Valley Encephalitis or Kunjin virus.

How can I stop mosquito from breeding in my backyard?

Check to make sure you don't have anything in your backyard that can hold water such as tyres or old drums. Make sure your septic tanks are completely sealed and the mosquito proof cowl on your vents is in good condition.

Do mosquitoes breed in grass?

No, mosquitoes need a permanent water body for at least 3 days to complete breeding cycles.
