A mid-sized Chatuchak animal hospital director runs 2 rai with clinic, surgery, recovery rooms, and an outdoor exercise area, handling 60 dog/cat cases a day. Mosquitoes bite staff and — more critically — transmit canine heartworm, the most serious vector-borne risk in the field. The World Health Organization classifies mosquitoes as the deadliest animal on Earth — 725,000+ deaths annually. Thailand DDC reported 100,000+ dengue cases and ~100 deaths in 2025. Animal hospitals at a Chatuchak animal hospital chose AIROFOG AT35 as the primary defense.
Heartworm spreads via mosquito bite. Dogs recovering in the hospital who are bitten may acquire infection on top of the original problem — worsening cases and damaging reputation. Mosquito density peaks between 16:00 and 19:00 — the Aedes feeding window. People outdoors take 15-30 bites per hour. Skin-sensitive individuals develop rashes. Topical repellents are expensive and trigger allergies.
The outdoor exercise yard for recovering pets must be clean and mosquito-free, or owners will switch clinics. Management is responsible for the health and safety of those in care. Mosquitoes carry dengue, chikungunya, Zika, and lymphatic filariasis — real threats requiring real preparation.
Mosquito coils and hand sprayers have limits. Coils cover only the immediate ring. Hand sprayers wet only leaves the nozzle reaches, missing leaf undersides and crevices under bridges and flower beds. External pest-control vendors are expensive, visit monthly at best, and mosquitoes return within days.
The clean solution: own the equipment, train 1-2 designated operators, schedule weekly sprays, and use Department of Agriculture-registered chemicals at safe concentrations. AIROFOG AT35 meets the requirement.
AT35 is a 6.6 kg shoulder thermal fogger with a 5.6-liter tank, 25.5 kW pulse-jet engine, and 35 L/hr maximum output. A 0.5-50 micron droplet spectrum drifts 15 m horizontally and 8 m vertically, penetrating tree hollows and crevices where mosquitoes shelter.
Made in Taiwan by AIROFOG (ISO 9001, CE). Used by Thailand DDC, every provincial public health office, 5,000+ local government units, the Royal Thai Army, and major hospitals. WHD is the official Thai distributor with lifetime support.
Fog drifts 15 m horizontally; covers a 1.5-3 rai veterinary hospital in 20-30 minutes. Two sprays per month deliver complete protection.
Spray 1-2 hours before activity. Fog dissipates; residual chemistry protects 7-14 days. Animal hospitals spray 7:00 pre-opening and 19:00 closing — off-hours from pet exercise
Pull-cord start, single throttle valve. One-hour training. No engineering background required.
External vendor cost: 100,000-150,000 baht/year. AT35 plus chemicals for a year: 50,000-60,000 baht. Payback in 6-12 months; 80-90% annual savings thereafter.
0.5-50 micron thermal fog penetrates tree hollows, bridge undersides, tent floors, flower beds — every refuge mosquitoes use. Conventional cold foggers cannot.
