Aerosol Safety in the Home

Aerosols have been used and stored safely in homes for over 60 years. There are very few aerosol accidents and those that do occur are usually caused by not following the instructions on the product label or deliberately misusing products.


The industry takes great care in the design, production and testing of aerosols and all aerosols are tested at elevated temperatures so they can cope with reasonably foreseeable conditions.

Many aerosols contain gases and liquids that may be flammable near a fire or heat. They also contain contents under pressure. This pressure increases with heat and may cause the can to burst.

So remember to always carefully read and follow the label instructions.

It is important to remember:

  • Aerosols must be kept away from heat, sunshine, window sills, heaters, ovens, barbeques and any ignition source (e.g. candles or pilot lights).
  • Never keep aerosols in cars because temperatures can rise quickly even on cool or overcast days.
  • Do not pierce or burn aerosols, even when empty as they may explode.
  • Do not spray near a naked flame, fire or source of ignition.
  • Do not smoke when using an aerosol or immediately afterwards.
  • Store in a cool, dry area. Damp conditions should be avoided to prevent corrosion.
  • Do not allow them to freeze in cold weather. 

For more information on an aerosol product or if you are involved in a safety incident, call the marketer’s customer call line, usually provided on the label. In case of an emergency, always dial 000.


These products are a popular method of treating any large scale or persistent infestation but can be dangerous if you do not carefully follow the safety advice on the product packaging and can.

To minimise the chance of fire or explosion, including the risk of serious injury, ensure that you read the product label carefully and follow all the instructions supplied by the manufacturer.  These include only using the recommended number of cans for the size of the room and eliminating all ignition sources prior to and during use.

To eliminate ignition sources, switch off the electricity at the mains and turn off gas pilot lights, such as pilot lights for stoves and hot water systems. If you cannot switch the electricity off at the mains, then switch off all power points, lights and electrical devices in the building at the wall switch.  This includes fridges and other electrical devices that turn themselves on and off during normal operation.

You also need to ensure that there is no smoking in the vicinity of the area in which the “Bug Bomb” is to be used.  

If you live in a multiple unit building, inform your neighbours and the building manager that you will be using “Bug Bombs” in your unit.  These buildings sometimes share common ventilation systems, or may have cracks and crevices between units. Make sure you let your neighbours know when you are using any “Bug Bombs,” and ask them to turn off any ignition sources if the units share common ventilation.

Before turning the electricity and pilot lights back on, ensure that the room has been fully ventilated by opening the windows and doors for the minimum time detailed on the product label.
