House Flies & Cluster Flies

How to Get Rid of Flies

If you have a problem with flies in your home, there are ways you can address the problems without spending money on pest control.

The best results will be achieved by doing some thorough house cleaning.

Other tips: Control moisture (fix leaky taps and blocked drains where water can gather – flies need moisture to multiply), keep food covered (leftovers should be covered up and any crumbs cleared away), keep your bins, sinks and food areas clean, cover entry points (fit fly screens to windows), keep windows and doors shut at night, keep bird feeders clean and remove bird food at night, and, finally minimise areas of clutter.

If problems persist, or the problem is identified as Cluster Flies, then paying for a residual spray and/or a fumigation will be the best short term solution.

Long term solutions (most often employed for Cluster Flies, and kitchen areas) usually involve the installation of an electric fly killer.

Cluster flies usually infest a house / premises by gaining access via construction joints / breaks in the exterior of a building.

They tend to harbour around the south / south west facing side of any premises, and are often noticeable around light fittings and window frames.


Life History


Laid on soil under leaves in the autumn. Hatch in one week


Parasitic – bores into earthworms and over winters. In spring – after approx. 10 weeks – it proceeds to move along the hosts body and at one stage perforates the body wall to expose its spiracles to the air. Eats its way through its host, breaks through skin and pupates.


In soil for 6 weeks


Fly relatively slowly, lives outdoors but congregates on posts and fences in sun and migrates into roof voids etc. in autumn. This insect only tends to become a pest when it hibernates in late summer / early autumn. This it does in roof voids and attics nearly always in the same general area and normally on the warmer southern side.

Cluster flies commence hibernation normally when triggered by a sudden drop in temperature such as an early frost. There are as many as three generations per year in the UK.
