More Details

Pest Expert Formula 'C+' Cluster Fly Spray contains cypermethrin (0.1% w/w), which kills cluster flies fast and leaves a long-lasting residue that maintains cluster fly control for up to 12 weeks.

Formula 'C+' is a ready-to-use insecticide that is safe for direct application to alighting surfaces including window frames and roof timbers. As Formula 'C+' is water-based and low odour, it is ideal for treating cluster fly infestations in both domestic homes as well as commercial premises.

One litre provides effective coverage to an area of approx 20 sq m. The product is supplied in a bottle with an adjustable trigger spray to enable a thorough and even distribution of insecticide.

For a comprehensive cluster fly treatment, we recommend using alongside Pest Expert Formula 'P' Cluster Fly Powder and Pest Expert Formula ‘P+’ Foggers as the combination of different active ingredients enables a faster and more effective knockdown.

Alternatively see our Cluster Fly Killer Kits for a complete package of the best cluster fly killer products on the market.

How To Use Pest Expert Formula C Fly Killer Spray

1. Screw the spraying mechanism tightly into the bottle.
2. Apply 1 litre of Formula C per 20 square metres or directly at insects
3. Allow 45 minutes – 1 hour for the solution to dry.
4. Wear suitable protective clothing and gloves.
5. Cover all water storage and fish tanks before application.

SPACE TREATMENT: Apply 1 to 4 ml of product per m3 as a fine mist
SURFACE SPRAY: apply 20 ml of product per m2, slightly wetting the surfaces to be protected.

Maybe 1L of spray was overkill but it seems to have done the job and still have more than enough left for next year!

We have a big problem with cluster flies.

Cost a furtune in professional fees last year.

Our local pest control man recommended this product and we hope it works. Its not yet cold enough for the cluster flies to have come into our loft but fingers crossed it will work when they do

Fantastic Product! Does exactly what it says on the label

Bought this second year in a row due to its amazing and long lasting effectiveness against flies. Sprayed it on velux windows around the house and everyday for a week or so we could see dead flies near the windows. Very effective when used in combination with smoke fumers.

At last! After trying all the readily available off-the-shelf fly sprays, I've finally found one that does what it says on the tin - kills flies.

It is by far the best insecticide out there , you apply it once and it causes carnage to any undesirable infestation, all is left the day after is to do a body count.

Nothing works better!

Used this in our shop as it's a very old building and we get a LOT of crawling insects inside.. One spray around the shop, all round the edges and doorways and the next day we went in there were many many dead insects everywhere! After that we had months of insect free days. Six months on and they just starting to appear again so we have purchased another spray gun to eliminate them again. If you don't like insects then this is the spray for you!

I have used this around all my door frames and window frames and in cracks, skirting boards and cupboards. I have only had a couple of flies in the house so it could well be working. I have used the full bottle of it so I may order some more soon.
