Three methods, three completely different jobs. Fog and mist are liquid droplets that hit exposed pests and coat surfaces. Fumigation is a gas that fills a sealed space and reaches what droplets never can. Pick the wrong one and you pay for a treatment that cannot solve your problem. Here is how to match the method to the pest, what each costs in Dubai, and the licensing rules you need to know before you book.
Almost every wrong booking comes from missing a single distinction. Fog and mist are suspended liquid droplets. They drift through the air, contact exposed insects, and settle onto surfaces. They only treat what they can physically reach.
Fumigation is a true gas. Released into a sealed, airtight enclosure, it fills every void and penetrates cracks, timber, and the inside of packaged products. Gas is molecule size, fog is micron size, and that gap in scale is the whole story. A droplet cannot squeeze into the pores of a wooden beam or the middle of a sealed grain sack. A gas molecule can.
If the pest is out in the open, a liquid droplet can reach it. If the pest is hidden deep inside a structure or a product, you need a gas in a sealed space. That single test decides most jobs.
Thermal fogging. An insecticide, usually oil-based, is heated into a dense, visible white fog of very fine particles (approximately 0.5 to 10 microns; sources vary). It is built for large open outdoor areas where you want fast, wide coverage of adult mosquitoes and flying insects. The thick cloud drifts across gardens, grounds, and community spaces. It is not for enclosed indoor use.
Cold or ULV fogging. Air pressure atomises a solution, usually water-based, with no heat, producing a near-invisible fine mist (approximately 5 to 30 microns; sources vary). Because there is no heat and the carrier is water-based, it is safer for indoor and enclosed spaces such as warehouses and offices, and it doubles as a disinfection method. It targets flying insects and some exposed crawling insects.
Misting. Misting uses larger droplets (approximately 50 to 100 microns) that settle to leave a residual surface barrier, often delivered through fixed or automatic nozzle systems around villas and outdoor seating. It suits residual control of crawling pests and ongoing outdoor mosquito suppression. For the full breakdown of how ULV misting works, the active ingredients, and villa scheduling, see our misting and ULV fogging guide.
Fumigation. A penetrating gas is released into a sealed, airtight enclosure. It is the answer for whole-structure or whole-commodity problems: stored-product pests in warehouses and containers, grain, wood-boring insects and drywood termites inside timber, severe hidden infestations, and export or quarantine treatment. The modern standard fumigant is sulphuryl fluoride (SO2F2). Methyl bromide is being phased out globally under the Montreal Protocol because it depletes the ozone layer, so it is now restricted and not routinely used.
Describe the pest and the space on WhatsApp. We will tell you honestly whether you need fogging, misting, or true fumigation, and quote it same day.
| Method | What it is | Best for | Reaches eggs? | Occupied during treatment? |
|---|---|---|---|---|
| Thermal fogging | Heated oil-based insecticide as a dense visible fog | Large open outdoor areas, adult mosquitoes and flying insects | No, adult knockdown only | Cleared briefly, short ventilation time |
| Cold / ULV fogging | Cold-atomised water-based mist, near-invisible | Indoor and enclosed spaces, flying insects, disinfection | No, adult knockdown only | Cleared briefly, short dry and ventilation time |
| Misting (residual) | Larger droplets settling to a residual surface barrier | Residual crawling-pest control, ongoing outdoor mosquito suppression | No, does not reliably reach harbourage or eggs | Cleared briefly, short settling time |
| Fumigation | Penetrating gas in a sealed, airtight space | Warehouses, containers, timber, whole-structure hidden infestations | Penetrates deep, but weaker on eggs at standard doses | No, space must be fully vacated and sealed |
That usually means the eggs were never reached. Send us the details and we will recommend the treatment that actually clears the infestation.
Fogging kills the eggs. It does not. Fogging knocks down exposed adults. Eggs sit protected in harbourage the droplets never reach, so a repeat visit timed to the hatch is often needed.
Fumigation is just a fancier word for fogging. Wrong. Fumigation is a gas released into a sealed space. Fogging is liquid droplets in open or ventilated air. They are not interchangeable.
A DIY fogger will clear bed bugs. It will not. Consumer foggers miss the eggs and deep harbourage, and bug bombs are documented as ineffective against bed bugs.
Thermal fog is stronger because you can see it. The visible cloud is just the heated carrier, not extra strength. ULV fogging can carry an equally effective active ingredient in finer droplets, and it is safer indoors.
These figures are indicative and vary by property size, pest, and company. Treat them as a planning range, not a fixed quote.
One warning worth repeating: some listings advertise cheap fumigation that is really a fogging or spray upsell. If a price looks far below the fumigation range above, ask exactly what method and permit the job involves before you book. Our pest control cost guide breaks the pricing down further.
Pest control in Dubai is regulated, and it matters for fumigation in particular.
PestsGone is a Dubai Municipality-approved company using only approved chemicals. The right method for your property depends on the pest, the structure, and the level of infestation, so we defer the specifics to a site survey rather than guessing over the phone.
