Best Fogging Machine for Dengue Control in India
By 100X Circle Pvt Ltd · 5 min read · Updated May 2026
Dengue is caused by the Aedes aegypti mosquito — an urban species that breeds in clean water containers and bites during daytime. Thermal fogging is the primary adult mosquito control method used by Indian municipalities during dengue outbreaks. This guide covers equipment selection, chemicals, and operation.
Verdict: Depends on Your Use Case
For ward-level dengue drives, a vehicle-mounted thermal fogger is essential — it covers entire residential areas quickly. For spot treatment of specific hotspots, housing societies, and narrow lanes, a portable fogger complements the vehicle-mounted operations. Both are available from 100X Circle on GeM.

Frequently Asked Questions
Does fogging kill dengue mosquitoes?
Yes. Thermal fogging with WHO-recommended pyrethroids (deltamethrin, cypermethrin) kills adult Aedes aegypti mosquitoes on contact. It does not eliminate larvae — anti-larval operations (removing standing water, applying larvicide) must be conducted alongside fogging for sustained dengue control.
What is the best insecticide for dengue fogging?
Deltamethrin 1.25% (technical grade) in carrier oil is the WHO-recommended insecticide for thermal fogging against Aedes mosquitoes. It has low mammalian toxicity and high mosquito contact kill. Cypermethrin (10% in oil) is also commonly used by Indian municipalities.
When should fogging be done for dengue control?
Dawn (6–8 AM) or dusk (6–8 PM) — when Aedes aegypti mosquitoes are most active and wind is minimal. Fogging in midday heat or strong wind is ineffective as fog disperses before mosquito contact. Daily fogging during outbreak season (July–November) in high-incidence wards.
