Thermal Fogging Machine and a Quarterly Mosquito Control Calendar for Fiscal Year 2570 (October 2026 to September 2027): Machine Checks, Training, Pre-Rainy-Season Spraying and Outbreak Response for Local Governments

Thai fiscal year 2570 runs from 1 October 2026 (2569 in the Thai calendar) to 30 September 2027. For local administrative organisations, it is a chance to turn mosquito control from reacting to cases into a plan laid out by quarter. This general guide splits the year into four quarters and explains what to do with your mosquito foggers, your team, your community and your budget in each, and where the AIROFOG AT35 thermal fogging machine fits.

1-minute summary

• Q1 (Oct to Dec 2026): review last year, inspect every mosquito fogger, schedule servicing and start procurement for items funded this year. The southern Gulf coast is typically still in heavy rain, so stay ready to spray there.
• Q2 (Jan to Mar 2027): the dry months are ideal for training staff and village health volunteers, practising with machines, accepting new equipment and surveying Aedes breeding sites.
• Q3 (Apr to Jun 2027): run "3 Keep" campaigns, spray before school opens and before the rains, and stock chemicals and protective gear.
• Q4 (Jul to Sep 2027): dengue cases often rise in many areas. Respond quickly within about 100 metres of each case and gather data for FY2571.
• Core tool: the AIROFOG AT35 thermal fogger, 100% stainless steel, lightweight, works with water- and oil-based chemicals, certified in Germany and the UK.

What went wrong last year (illustrative scenario)

Somsak, chief administrator of a subdistrict administrative organisation in the lower north of Thailand, remembers last July clearly. The subdistrict's first dengue patient was a primary school pupil. Within two weeks there were a second and third case in a neighbouring village. The team rushed the thermal foggers out of storage. One would not start because it had not run since the previous season. The other started but produced an uneven fog.

The machines were only the beginning. Chemical stocks were too low for repeat rounds. The officer who had been the best operator had transferred to another agency. New staff and volunteers had never been trained. When Somsak tried to buy a new machine, he found no equipment line had been budgeted that year, so it would have to wait for the next fiscal year. Meanwhile the village chat groups filled with the same question: "When is the SAO coming to fog?"

Looking back, Somsak saw that every problem was preventable with planning. The machine that would not start should have been checked at the end of the previous season. New staff should have been trained in the dry months. Chemicals should have been stocked before the rains. The equipment request should have gone in during the budget cycle. Fiscal year 2570 is the chance to do each of these at the right moment.

The cost of having no calendar

Health

Aedes mosquitoes carry dengue, chikungunya and Zika. Dengue brings high fever, headache and muscle pain, and some cases become severe enough to cause shock. Children, older adults, people with chronic conditions and pregnant women are most at risk. In some forest and border areas, Anopheles mosquitoes still transmit malaria. Every day of delay in vector control is a day in which infected mosquitoes can reach the next household.

Budget

Without a plan, local governments end up buying in a hurry, purchasing chemicals piecemeal and paying for emergency repairs without negotiation. If no equipment line was budgeted, a new machine slips a full fiscal year.

Public trust

Residents remember whether their local government came quickly or late. Complaints on social media and through complaint centres spike when cases appear. By contrast, a local government that publishes its spraying schedule in advance and keeps to it earns trust from village leaders and residents.

Staff workload

Unplanned work piles into a few weeks: spraying morning and evening, paperwork and public questions all at once. A quarterly calendar moves preparation into quieter periods, so outbreak season is left with only the essential response work.

Why the usual approach fails

Old machines left unchecked. A thermal fogger stored for months without running or cleaning is likely to fail on first use: ignition problems, clogged nozzles or chemical residue.

Spraying at the wrong time. Thermal fogging works best in the early morning or evening, when mosquitoes are active and the air is cooler. At hot midday the fog rises and disperses quickly, wasting chemical.

Spraying without source reduction. Fogging kills adult mosquitoes, but larvae in water containers keep producing new ones. The Department of Disease Control's "3 Keep" measures (keep the house tidy, keep rubbish managed, keep water covered) must run all year.

Cheap, non-standard equipment. Machines with no local agent, no spare parts or materials that do not resist chemicals often last only a few seasons, and no technician arrives when they break.

Missing the budget cycle. Mosquito control gets attention in the rainy season, but next year's budget is drafted before that. Without data prepared in advance, the equipment you need never makes it into the request.

The AIROFOG AT35 thermal fogger in the FY2570 calendar

The AIROFOG AT35 is a thermal fogging machine with a 100% stainless steel body. It is lightweight, works with both water- and oil-based chemicals, and is certified in Germany and the UK. Its product page lists homes, factories, hospitals and public areas, which covers nearly every place a local government looks after.

In a quarterly calendar these features take on specific meaning. Stainless steel stands up to heavy use and to storage between seasons. Light weight means the staff and volunteers trained in Q2 can handle it comfortably in Q3 and Q4. Compatibility with water- and oil-based products gives flexibility to source whichever chemicals local health authorities recommend.

WHD, the supplier, holds ISO and GMP, runs 100% quality control before delivery, and provides technicians, spare parts and after-sales service. The machine meets Thai government equipment standards. That support matters most for the inspection and servicing work scheduled in Q1 every year.

Q1: October to December 2026, close the old year and open the new

The first fiscal quarter is the tail of the rainy season in the central, northern and northeastern regions, while the southern Gulf coast is generally in its wettest period. Work splits two ways: review and servicing where the rain is easing, and readiness to spray where the risk continues.

Common mistake: starting procurement late. Begin in Q1 and a new machine can be delivered, accepted and staff trained before the rains. Wait until Q3 and it may arrive with the first patient.

Southern Gulf coast note: this is usually the main rainy season there, so reverse the order: spray first, service after the rain eases. Check disease status with your provincial health office or regional disease control office.

Q2: January to March 2027, the dry months are for people

Spraying demand eases in many areas, making this the best time to develop your team and take delivery of new equipment. Do not let it slip, because Q3 leaves no room for training.

Simple training format: a short theory session on the Aedes life cycle, biting times and chemical safety, then hands-on practice where every trainee starts, adjusts and cleans the machine. A lightweight unit like the AT35 makes practice easier for first-time users.

Q3: April to June 2027, spray before the rains and before school

In much of the country the rainy season generally begins around mid-May, and most schools open their first term at about the same time. This is the most important window of the year: cutting the mosquito population before rain creates breeding sites everywhere lowers the chance of an outbreak later.

Time it right: fog in the early morning or evening when the wind is calm. At schools, fog on holidays or after classes, and observe the re-entry interval on the chemical label.

Next year's budget: local governments generally draft the following year's budget ordinance around mid-fiscal-year, and equipment items usually need to align with the local development plan. Confirm exact deadlines with your finance and planning units, and bring the Q1 and Q2 data to support the request.

Q4: July to September 2027, outbreak season and fast response

In many areas dengue cases tend to rise from the middle to the end of the rainy season. This quarter tests everything prepared earlier. The goal is vector control as soon as possible after a case is reported.

Indicators worth keeping: time from report to first spray, households covered in the full ring, number of machine breakdowns and chemical used. This evidence carries weight when requesting equipment or consumables next year.

One-page FY2570 overview

This is a general guide. Seasons and outbreak timing vary by region and by year; adjust to your local health authority's data.

Adjusting the calendar to your area

Central, northern and northeastern regions: the calendar above generally fits as written, with the main risk window in Q3 and Q4. Upland and border areas should also check whether malaria vectors are a local concern and coordinate with the regional disease control office.

Southern Gulf coast: heavy rain usually falls from roughly October to January, so Q1 is a response quarter, not a servicing quarter. Move the major inspection to Q2 and the training to late Q2 or early Q3.

Andaman coast: the rainy season tends to be long, so plan for extended readiness and more frequent machine checks.

Urban municipalities: dense housing, markets and many water containers can keep Aedes active outside the usual peak. Keep at least one thermal fogger and one team on standby year-round, and add school term dates and major festivals to the calendar so fogging is scheduled before large gatherings.

10 reasons the AIROFOG AT35 fits a quarterly local-government calendar

1. 100% stainless steel body for heavy Q4 use and storage between seasons.
2. Lightweight, which suits Q2 training for volunteers and new staff.
3. Water- and oil-based chemicals give flexibility to follow local health guidance.
4. Certified in Germany and the UK, useful supporting evidence for procurement.
5. Listed for homes, factories, hospitals and public areas on its product page.
6. A visible fog that residents can see working, which supports Q3 campaigns.
7. WHD technicians and spare parts for Q1 inspection and servicing.
8. 100% quality control before delivery, lowering the risk of problems at Q2 acceptance.
9. Meets government equipment standards, so it can be budgeted correctly.
10. Pairs with other units in the WHD range, such as the SOLO PORT423 backpack mosquito sprayer for ULV work. See the AIROFOG AT35 page.

Procurement tips that keep pace with the calendar

Start early. If the FY2570 budget ordinance includes a thermal fogger, begin in Q1 so delivery, acceptance and training finish in Q2.

Specify from real work. State what the job needs: a chemical-resistant body, compatibility with water- and oil-based products, weight suited to field use, and certificates the supplier can verify. Keep the wording open enough for fair competition.

Budget equipment and consumables together. The fogger is equipment; chemicals, fuel, consumable parts and protective gear are usually consumables. Confirm categories with your procurement and finance staff.

Write in after-sales service. Require operation and maintenance training, technicians, parts and a contact channel for breakdowns during outbreaks.

Keep evidence for next year. Log quarterly results, working machine counts and problems to support FY2571 equipment requests.

Start-of-year fogger inspection checklist

• Starts normally, fog is even, no unusual noise
• Chemical and fuel tanks do not leak; caps seal
• Nozzle and lines are clear with no residue
• Ignition system works as described in the manual
• Spare consumable parts on hand as the supplier recommends
• Results recorded on the machine's log card

Example field perspective

"This year we pinned a quarterly calendar outside the health office. At the start of the fiscal year we pulled out every machine and found two needed parts. In the dry months we trained volunteers in every village. When the rains came, each village had someone who could run a fogger instead of waiting for one officer from the SAO. And we had the data to take to management in time for next year's budget."

Terms executives should know, one line each

• Fiscal year: the Thai government budget year, 1 October to 30 September.
• Thermal fogging machine: uses heat to turn chemical into a visible fog; best outdoors.
• ULV cold fogger: sprays a small volume as very fine droplets without heavy smoke; indoors or outdoors.
• 100-metre ring: vector control around a case's home within roughly 100 metres to break transmission.
• 3 Keep: keep the house tidy, keep rubbish managed, keep water covered, against dengue, chikungunya and Zika.
• Equipment versus consumables: equipment lasts years (the fogger); consumables are used up (chemicals, fuel).

The thermal fogger alongside other tools

Thermal foggers suit outdoor areas such as temple grounds, school fields, markets and hedges around homes. Many local governments also have spaces needing different tools: classrooms and child development centres, where an electric ULV cold fogger is more appropriate, or narrow lanes that suit a backpack mosquito sprayer. The calendar should state which machine type each task uses so no single unit is overworked.

Beyond mosquitoes, local governments face other pests in some seasons, such as flies at markets and waste points. Planning all insect control in one calendar makes the best use of machines and chemicals, as long as registered products are matched to each target insect.
