Commercial Fly Control Services

Flies can be a detriment to any business that relies on a pest-free environment.

But, because flies can enter your business every time someone opens your door, controlling them can be challenging.

 

PGM & SON has extensive experience in commercial fly control.

​

In addition, and what makes us unique from other pest control companies, is that we offer sanitising and disinfecting services to remove rodent - bird - wildlife urine and droppings to create a disease-free environment for our customers, their families, and their businesses.

Cluster Fly (Pollenia Rudis)

​

 

Habitat

In the summer they live and breed in fields so they are not normally a problem. Although they may enter buildings, for example:

  • Hereford residential properties

  • Hereford Hotels

  • Hereford Restaurants

  • Hereford farms

  • Hereford bed and breakfast

  • Hereford schools

  • Hereford commercial properties

 

They hibernate in the Autumn and sometimes in vast numbers. They will hibernate around windows and in roof spaces. Although they are found across the UK, they are mainly found in rural areas because of their life cycle.

​

Breeding

  • The cycle is: egg, larvae, pupa, adult

  • Eggs are laid in damp soil or in rotting vegetation

  • The larvae seek out a host (normally earthworms). They are parasitic on earthworms

  • The pupae live in the soil

  • Adults are around 6mm long. Their colour is blackish and there are often 2 generations per year

 

Although these insects don’t bite, they’re considered a nuisance because of the volumes in which they migrate into a property to hibernate over winter. Naturally, you don’t want to share your property with swarms of flies and for a business, it’s not a great way to attract customers either.

Since this is a free living field insect, the life cycle is dependent on our weather. In Britain it is most likely to have two generations per year but if it’s very hot, this may be up to four.

​

Identification

  • Sluggish behaviour and a low bumbling buzz

  • Flies seen late at night when the lights are on are most likely to be cluster flies

  • Agitated bouncing around near a light fitting or close to light bulbs

  • Infestation in the loft

  • You may see unsightly tiny dark coloured spots of excrement on walls or windows that are difficult to clean

  • If they die in areas such as wall voids or false ceilings you may find you have a secondary problem such as the attraction of other pests (e.g. larder beetles)

​

Control Measures

  • There is very little you can do – proofing works may help reduce the problem

  • Controlling the problem is far more effective – for example, with use of insecticides (smoke generators) and treating around window frames

  • Care must be taken when using any insecticide due to the possibility of bats living in the building. Bats are protected under the Wildlife and Countryside Act 1981

​

At PGM & Son we see a lot of problems with cluster flies in Hereford and particularly the surrounding rural areas where it is common in Autumn for them to congregate in large numbers on the outside of buildings especially on sunny, south-east facing, light-coloured walls. As the afternoon temperatures begin to fall they tend to crawl into crevices for shelter, sometimes through window frames, but mainly under the eaves/fascia boards into the roof space
