Fog Scents & Scent Machines

Smell makes a scene believable. Froggy's Fog UK supplies the full Froggy's Fog scent range: additives that scent your fog, haze, snow and bubble effects, spray-on scents for props and actors, and scent machines that fill a room on their own. Choose from nearly 60 smells, from fresh linen and gingerbread to rotting decay and raw sewage. Stock orders leave our UK warehouse the same or next working day.

Which scent product do I need?

  • Water Based Scent Additives (1 oz or 2 oz): add a scent to the fog, haze, snow or bubble fluid you already use. Works in any water-based machine, so the smell arrives with the effect.

  • Scented Scene Sprays (1 fl oz): spray onto props, costumes, walls or actors. One application lasts 2 to 3 days.

  • Scent Distribution System, 250 sq ft: a battery-powered, wall-mounted box that scents about 23 m² for 45 to 60 days on one D-cell battery and one scent cup, with no daily upkeep.

  • Scent Distribution System, 500 sq ft: covers about 46 m² and is controlled from a phone or tablet app over Bluetooth, with 7 days of programming and 3 timed scenes a day.

  • Scent Cup Replacement: refill cups for the 250 sq ft box, each giving 45+ days of constant scent.

  • Oil Based Scent Refill (4 fl oz): one bottle refills the 500 sq ft system.

How much scent additive do I use?

For attractions, events and training

Scare attractions use scents to make each room feel different, retailers and venues use pleasant aromas to set a mood, and fire and rescue trainers add smoke and fuel smells to make simulated smoke more realistic. Every format works alongside our fog fluids and machines.

UK delivery

Orders for items in stock are dispatched from the UK the same or next working day, so there's no waiting on imports or customs. Safety data sheets for our scents are available on request for your risk assessments and venue paperwork.

Scent FAQs

Can I add a scent to my fog machine?

Yes. Add half an ounce (about 15 ml) of Froggy's Fog Water Based Scent Additive to every 3.7 litres of fog fluid. It works in any water-based fog, haze, snow or bubble machine.

How long does a scent cup last?

Each Froggy's Fog scent cup gives 45+ days of constant scent in the 250 sq ft Scent Distribution System, which runs 45 to 60 days on one D-cell battery.

How long does scent spray last?

One application of a Scented Scene Spray lasts 2 to 3 days on props, costumes or walls.

What's the difference between the two scent machines?

The 250 sq ft box is battery powered and runs continuously on a scent cup. The 500 sq ft system covers twice the area, uses oil-based refills, and is scheduled from a phone or tablet app over Bluetooth.

Nearly 60, from pleasant aromas like Fresh Linen, Vanilla and Gingerbread to horror smells like Rotting Decay, Charred Corpse and Raw Sewage. We stock the most popular scents in each format and can order any of the range on request.

Can scents be used for fire and rescue training?
