DIY – 11 ways to prevent and treat Blowflies (bluebottles) and maggots

The blowfly or bluebottle is found worldwide and is often associated with humans and their activity.

Blowflies bored on dead, decaying animal matter and lay clusters of eggs in fresh and older meat products and occasionally within excrement.

After laying the egg it will take around 1 day for it to hatch and the larvae will appear. The larvae will the burrow into the food source and after a period of around 1 week will resemble what we commonly call a ‘maggot’.

At this stage the maggot will leave the food site in search of a place to pupate (usually within soil). In homes, factories, waste bins when a suitable pupation site isn’t possible areas can become heavily infested.

Point to note that maggots/blowflies are prolific at spreading pathogens and disease so please read and implement these 11 points below.

 

Prevention

  • Keep meat waste in a sealed container, better still keep it in a sealed container that is kept refrigerated until the day of the waste collection.
  • If you pet uses an area of your garden/patio as a toilet please ensure you pick up and dispose of faeces, minimum of once per day.
  • Cover all meat food sources when left out of the fridge

Prevention – food handling premises

  • Fit fly screens/mesh on windows
  • External doors should be fitted with fly screen
  • Consider the location of an electric fly killer (ELK). Not in line of sight of windows, door etc – we don’t want to attract flies in.

Treatment

  • Prevention, prevention, prevention
  • Remove any rodent/bird carcasses (typical if you have a rodent infestation that has used bait and if you have pigeons living within the property)
  • Ensure all maggots have been collected and disposed of
  • Use an appropriate aerosol insecticide and/or a wet spray residual if large numbers of flies are settling in one area. (please always read, understand and implement the relevant safety precautions)
  • If in doubt speak to a professional pest controller

Flies problems occur in greater numbers during the warmer months.

Greenbottles – generally similar to the bluebottle (although metallic green in colour and favour external food sources – mainly faeces) Greenbottles can differ in size depending on the quality of their food source.

Hope this helps,
