Professional Cluster Fly Treatment
Cluster flies can quickly become a frustrating problem, especially as the weather starts to cool. Unlike typical house flies, they don’t just pass through, they settle in. Large numbers gather inside lofts, wall voids, and roof spaces, then begin appearing indoors when temperatures shift.
Once cluster flies have established themselves, they tend to return year after year unless the underlying issue is properly treated. That’s why a more thorough approach is usually needed rather than just dealing with the flies you can see.
What’s Included:
1. Contact & Quick Assessment
Book a quick, no obligation chat and we’ll assess the level of activity, likely entry points, and affected areas. You’ll get clear advice, upfront pricing, and a simple plan of action, no pushy sales, just straight answers from a trained technician.
2. On Site Survey
Your technician will carry out a thorough inspection to confirm cluster fly activity, identify entry points, and locate where they’re harbouring. We typically check lofts, roof spaces, upper floors, and external access points before agreeing on the most suitable treatment plan with you.
3. Treat & Protect
We use targeted treatments such as ULV fogging or residual insecticides to reach flies hidden in lofts, voids, and other hard to access areas. Once treatment is complete, we’ll provide practical advice on sealing entry points and reducing the chances of future infestations.

“Highly recommend, I phoned for some assistance with a newly discovered wasps nest and they had someone with me the same morning. Super friendly and helpful, wouldn’t hesitate to use these guys again should the need arise. We were left with an aftercare sheet also which was really useful.”

Why Cluster Flies Keep Coming Back
Cluster flies typically enter properties in late summer or early autumn, looking for sheltered spaces to overwinter. They remain hidden for months, then suddenly emerge during warmer spells, often catching people off guard.
You’ll usually notice them around windows, ceilings, or light fittings, often moving slowly and gathering in noticeable groups. While they don’t pose the same health risks as some pests, the sheer number of them can make living or working in the space uncomfortable.
The issue is that most of the infestation stays hidden. Vacuuming or spraying visible flies might seem to help at first, but it rarely touches the source, which is why the problem often comes back.
Signs of Cluster Flies
- Large numbers of flies appearing indoors during autumn, winter, or early spring
- Flies gathering around windows, loft hatches, or upper floors
- Slow moving flies that seem sluggish but persistent
- The same issue returning each year
Catching the problem early can make a noticeable difference in how quickly it’s resolved.
Cluster flies return because they use the same buildings to overwinter. If entry points and harbouring areas aren’t treated properly, new flies will re-enter the same spaces each season.
Fogging is very effective at eliminating active flies hidden in lofts and voids. However, long term control also depends on reducing entry points and preventing new flies from getting inside.
In most cases, you may need to leave the treated room for a short period during fogging. We’ll explain exactly what’s required before we start so there are no surprises.
You may notice some activity shortly after treatment as hidden flies come into contact with treated areas. This usually reduces quickly over the following days as the treatment takes full effect.
