The Pest Expert Formula 'P' Cluster Fly Super Fumer Smoke Bomb is more than three times the size of a standard Fumer, so able to treat an area 3 times greater. Perfect for eradicating cluster fly infestations in larger spaces such as lofts and open-plan living areas. 

  • Powerful cluster fly killing fumigation device
  • Fast knockdown of cluster flies in lofts or roof spaces
  • Treats an area of 400m3 - 3 times that of a standard Smoke Bomb.
Product Information
The Formula 'P' Super Fumer Cluster Fly Smoke Bomb is a more powerful fumigation device than a standard Smoke Bomb, treating an area three times greater, which makes it ideal for getting rid of cluster flies in lofts, roof spaces or open-plan living areas. One Super Fumer will treat a space of 400 cubic m (approx 16m x 10m with a standard ceiling height of 2.5m)

The Super Fumer contains 11g of the active ingredient Permethrin at 13.25% w/w as opposed to 3.5g in the standard Fumer. Once lit, an insecticidal smoke is released as the Fumer smoulders, which disperses to fill the room/roof space, killing all cluster flies present at the time of treatment.

Directions for use
Check roof spaces for bats or evidence of bats.

Pets/children should be kept out of area at time of treatment and until gas has completely dispersed (2-3 hours). Any fish tanks should be removed and water tanks in lofts should be covered.

Make the area to be fumigated as smoke tight as possible by closing all windows, doors etc.
Place smoke bomb(s) on a heat-resistant surface, for example a biscuit tin lid or an old plate. Handle with care after use as they can become quite hot.
Light the fuse and vacate the room/area. Leave for at least 2-3 hours for the smoke to disperse and then ventilate the room thoroughly.
NB We would recommend wearing a safety mask when using this product.

Use when you notice signs of cluster fly activity. The Pest Expert Formula 'P' Super Fumer is an essential component in the treatment of a cluster fly infestation and is best used in combination with a residual insecticide such as Pest Expert Formula 'C' Cluster Fly Spray for longer-lasting cluster fly control.

Delivery was next day - as promised. I had to have the parcel delivered to a neighbour as I wasn't at home and we both received texts giving us a delivery slot - which was spot on. Well done! I certainly recommend this firm. Clusterflies all gone for now.

great company.... Very prompt delivery, as one would wish once you know that you have them in your loft... Killed 90% of them and believe me there were millions in there, we have a second dose to do them with this week and they're going to get it!

All good stuff, give them a go if you've got a clustering army making your skin crawl in your loft!

Reviewer: Alison from Reading   5 Stars

Ringing the help line for advice on how to deal with a clusterfly infestation in our attic i was impressed with your service from the start. The gentleman on the end of the phone was very knowledgable and helpful in suggesting the product to use and how it worked. The 'bombs' arrives 2 days later and fingers crossed we've seen the last of them for now! I have had no hesitation in recommending your company to friends

Reviewer: Des Connor from Carlow   5 Stars

This product is just great

I am involved in a sports club and we had an infestation of house flies. So we tried the smoke bombs. As we let them off there was very little smoke really and we were not sure the product was going to work. We had no need to worry! We left the hall over night and the next morning the place was just covered in dead flies. We had no idea there were so many flies in the place but it got rid of them all. Service from Pest Expert is just great. They let me know when the product had left their store and it arrived here in Southern Ireland in a couple of days. Great product and service. Thanks, Des.

Reviewer: Brid Scanlan Cullinan from Ennis   5 Stars

Ask and you shall receive.

Ordered smoke bombs for cluster fly infestation which had taken over our attic and was moving into the upstairs rooms. Ordered the smoke bombs. The arrived promptly. Set them off as directed and in an hour we seemed to have won the war. We set off the rest of the bombs a week later for any stragglers and we are now fly free. Thank you pest expert.

Reviewer: Paul Casey from Kerry   5 Stars

does exactly what it says on the tin

Have to give this company 10\10. I ordered my products on a Monday and they arrived on the Wednesday and im living in Ireland. I ordered smoke bombs to kill cluster files. With the order came gloves and a good quality mask. I no longer have cluster flies. Lol. Website is very easy to follow and I will be ordering again when the need arises
