Main Highlights

✅ FACT: THE NEW PEST EXPERT FORMULA 'P' FUMER PRO 7g IS DOUBLE THE SIZE OF ALL MINI SMOKE BOMBS SOLD ON AMAZON – Many smoke bombs are only 3.5g. Our 7g Smoke Bombs are DOUBLE the size, providing DOUBLE the coverage area, making them the most cost-effective smoke bomb on Amazon, whilst providing excellent results.

✅ THE STRONGEST FLEA & CLUSTER FLY SMOKE BOMB ON THE MARKET - Containing maximum strength Permethrin, this powerful fumigation device provides rapid knockdown of fleas & cluster flies.

✅ TOTAL INDOOR FUMIGATION SOLUTION – This smoke bomb will fully fumigate even the largest rooms, treating an area of up to 240 cubic meters, reaching all the areas you wouldn’t able to with any other products.

✅ FAST ACTING – Once ignited, this fast-acting smoke bomb kills fleas, cluster flies and other insects on contact.

✅ INTEGRAL FOR A COMPREHENSIVE TREATMENT – Formula P Smoke Bombs are integral to any comprehensive flea & cluster fly treatment, killing insects in the airspace.

✅ NON-STAINING AND LOW-ODOUR – After ventilation there will be no nasty residues or smells on any household furnishing, making it the perfect treatment in any home or business.

✅ Please Note: Always follow the instructions provided - Never place and light directly on to a carpet! - Always place on a suitable surface before lighting, for example a plate or metal tin lid and remove batteries or switch off any smoke detectors.

✅ Also: If treating for fleas, it is essential that you also have your pet treated by a qualified vet, or with suitable animal flea treatment products, such as Frontline. Simply fumigating a property with smoke bombs alone, will not be enough to achieve effective control, if your pet remains untreated and is still carrying fleas!
