Fly Control — Cambourne

Why Do Flies Keep Gathering at the Windows in My Cambourne Property?

In a modern Cambourne home, flies gather at the glass because they are trapped by light, but the number you see tells you whether they are being produced indoors.

Flies gather at windows because they are drawn to bright light and cannot get out. A modern home with well-sealed double glazing makes that worse, because there is no draught or gap to lead them towards the outside. A fly that arrived through the front door in the morning can spend the afternoon at the glass.

So a few flies at a window in a Cambourne house is normal. The real question is whether it is the same few or a fresh lot each day.

Counting Is the First Test

Wipe the sill clean in the evening and look again in the morning. A tidy-up and a couple of new flies means they are wandering in. A dozen or more means a supply.

Where a supply can hide in a newer house

  • An unused en-suite or spare bathroom. Little use means an undisturbed film in the waste trap, which is where small furry drain flies breed.
  • A bin store or integral garage with food waste or pet food in it.
  • The kitchen bin and recycling, especially unrinsed bottles and tins.
  • A boxed-in void where a bird or rodent has died, which produces larger blow flies.
Newer does not mean immune. New homes are not too clean for flies. A single neglected trap or a bag of food waste in the garage is plenty.

What the Windows Are Telling You

Look at the type of fly. Tiny ones hovering around the fruit bowl are fruit flies. Small, dark, furry ones sitting on a bathroom wall are drain flies. Large glossy ones buzzing loudly are blow flies, and if they are coming in numbers you should look for something dead. Windows just happen to be where all of them end up.

Sensible Things to Try First

  1. Pour a kettle of hot water, then a biological drain product, into any rarely used trap.
  2. Take out and rinse the recycling.
  3. Check the garage and the cupboard under the stairs for stored food.
  4. Fit a fly screen to the windows you open.

This clears a minor problem. It will not find a hidden source, and spraying the glass does not stop the next batch.

Why Trickle Vents Do Not Solve It

People sometimes assume that a trickle vent or an opened window will let trapped flies escape. A few do find the gap. Most carry on flying at the brightest pane, because the vent is small, high up and not where the light is. Lowering the blind or turning off a bright room light can help flies settle, but it just moves the problem around the room.

If your home is a few years old and you have never had flies before, the change is usually down to one specific thing: a drain that has dried out, a new bin habit or a delivery of something stored in the garage.

When to Call Someone

If you still have fresh flies every morning after a week, it is worth getting someone to find the source. fly control in Cambourne is £180 fixed cost and the price is agreed before work starts. Our fly control cost guide sets out what it covers.

Most Cambourne homes share the same sealed-window design, so what you learn about one pane applies to the rest of the house.

Common Questions

Do sealed windows in Cambourne houses attract flies?
Not in themselves. They just stop flies finding an exit, so those that get in end up at the glass.
How do I tell drain flies from other small flies?
Drain flies are dark, furry and sit still on walls near sinks and showers. Fruit flies hover near food and bins.
Could a spare bathroom be the cause?
Yes, if it is rarely used. The film inside the waste pipe builds up undisturbed and flies can breed there.
What does it cost?
Fly control is £180 fixed, with no call-out fee. We confirm the price before we begin.
