A Nong Sano sub-district administrator in Phetchabun oversees 7 villages and 1,800 households. In 2026 the office received 80,000 baht from the provincial public health office for annual mosquito-control chemicals. The TOR must specify a Department of Agriculture-registered product meeting WHO standards with guaranteed quality. The World Health Organization names mosquitoes the deadliest animal on Earth — 725,000+ deaths annually. Thailand DDC reported 100,000+ dengue cases and ~100 deaths in 2025. Deltamethrin is a WHO-recommended insecticide for dengue prevention. Axsorb Deltamethrin is the product Sub-district administrations and municipalities at Nong Sano OBT, Phetchabun choose.
Annual procurement attracts multiple bidders; some submit unregistered products or under-strength concentrations, leading to ineffective spraying and citizen complaints. Female Aedes mosquitoes feed at dawn (6:00-9:00) and dusk (16:00-19:00). A single female can lay 100-300 eggs in just 1 teaspoon of standing water; in 2 weeks the local population explodes.
Substandard chemical choices increase tambon dengue cases, expose leadership to responsibility, and risk negative provincial press. One dengue case in the community, if not met within 2-3 weeks by effective chemical control, becomes a 10-20-case cluster requiring intervention from the Department of Disease Control and the provincial health office.
Deltamethrin is a synthetic pyrethroid — engineered from natural pyrethrum but 10-50x more potent and far more persistent. WHO classifies it as Class II (moderately hazardous), an acceptable safety level for residential, public-building, and public-space spraying at recommended concentrations.
Mechanism: Deltamethrin binds insect sodium channels, paralyzing nerves and producing rapid knock-down — visible within minutes. Residual deposits on walls, floors, and foliage repel and kill incoming mosquitoes for 2-6 months depending on surface and weather.
Deltamethrin is registered with the Thailand DDC for Indoor Residual Spraying (IRS), Space Spraying (thermal/ULV fogging), and Insecticide-Treated Bed Nets (ITN). It is the lead chemical in DDC's Integrated Vector Management (IVM) strategy against dengue, chikungunya, Zika, and Japanese encephalitis.
