Cluster flies

New safety procedures for appointments

Our pest control service has reopened and we are now taking bookings, with some new coronavirus (COVID-19) safety measures in place.

You should not book if any member of your household:

  • has tested positive in the last 14 days
  • is waiting for results of a coronavirus (COVID-19) test
  • is showing any symptoms of coronavirus (COVID-19)
  • is currently self-isolating

Cluster flies are dark grey flies about 8mm long. In autumn they cluster in large numbers in upstairs rooms or lofts to hibernate and are known for their distinctive smell and sluggish flight, which makes them a nuisance in households.

Please be aware that we only treat cluster flies and can't help with treatment of house flies or blue bottles.

If you have a cluster flies problem:

We recommend that you have a professional treatment carried out. 

The price for residential pest control is £56.70

Business prices start from £97.50

Alternatively, you can call us on 0191 433 7000 to arrange treatment.

What happens at your appointment

On our first visit, the pest control officer will do some routine checks of the premise to identify where the flies are and how they will be treated.

After this, the officer will lay the chosen insecticide. They will then give you some advice on how to prevent the problem, which may include making repairs.

Usually the pest control officer will only need to visit once as the treatment lasts between six and 12 weeks. If needed, we can arrange a follow up.


We don't recommend that you use DIY treatment as it can be dangerous to the environment, yourself, children and pets.

How to prevent a cluster fly problem

The best way to combat cluster flies is to keep your property clean


  • Clean up spills and food waste
  • Store food in clean, lidded bins
  • Remove dead flies

Why cluster flies are a problem

Although cluster flies don't pose a huge health risk to humans, they can spread other disease and contaminate food.

They can also be a nuisance as they usually travel in large swarms of thousands of flies.

For businesses, cluster fly problems can harm reputation and can lead to investigation if the proper procedures are not in place to ensure premises are pest free.
