The Cost of Inaction: How Local Government Leaders Should Think When They Still Do Not Own a Mosquito Fogger

Many local administrations still rely on borrowing a mosquito fogger from a neighbouring office, or on waiting for a contractor's next free slot, and they believe this saves money. In practice, not owning the equipment carries several layers of hidden cost. This article gives mayors, chief administrators and local public health teams a simple framework that needs no guessed numbers, so they can decide calmly and on evidence whether it is time to own government mosquito control equipment.

Executive summary (1-minute read)

• The problem: without your own mosquito sprayer, your response to a dengue case slows down. You wait to borrow, wait in a queue, or wait for a contract. That waiting time is exactly when infected Aedes mosquitoes can keep spreading the virus.
• The hidden costs: at least five layers: public health, time, scattered budget leakage, public trust, and your ability to explain decisions to the council and auditors.
• The way out: use a "cost of inaction" framework to compare four options: borrow, contract out, buy your own, or procure jointly with neighbours. Then decide using your own local data.
• Match the machine to the job: the WHD government mosquito and insect control equipment hub brings thermal foggers, electric and battery ULV cold foggers, backpack units and vehicle-mounted sprayers onto one page.
• Next step: ask your health team to fill in the checklist below, then call 065-556-6294 or LINE @whd268 for specifications and a quotation to support your budget request.

A week in a small-town municipality (illustrative scenario)

Prasert is the mayor of a subdistrict municipality in a quiet district. His area has a market community, farming villages and two schools. For years the municipality never budgeted for its own mosquito fogger. Whenever a dengue case appeared, staff phoned the neighbouring subdistrict administration and borrowed its thermal fogging machine, or in some years hired a contractor to spray in rounds. Everyone felt that "we always get through it".

At the start of this rainy season, the local health promoting hospital reported a schoolchild with dengue fever in the market community. The municipality's public health officer called to borrow the machine as usual. This time the answer was different: the neighbour had cases of its own, the machine was out every day, and the wait would be several days. The usual contractor was fully booked because many offices were calling at once.

A few days later a second child fell ill in the next lane. A parent posted in the community Facebook group asking why nobody had come to spray yet. The post was shared widely. A council member raised it at the next meeting, and the chief administrator had to explain why a municipality with budgets for many other projects had no basic disease control equipment of its own.

When the borrowed machine finally arrived, it was an old unit that was hard to start, and no one on the team had trained on that model. The first spraying round did not go smoothly. That night Prasert sat down with his chief administrator and asked a simple question: was the money "saved" by not buying a machine really worth everything the municipality had lost that week? That question is the heart of this article.

Why the cost of inaction is so easy to overlook

When leaders consider buying equipment, the number in front of them is always the price on the quotation. It is clear, concrete and must be justified to the council. The cost of not buying never appears on any document. It is spread across lost days, residents' illness, staff overtime and slowly eroding trust. When one side of the scale is visible and the other is invisible, decisions tend to lean towards "let's postpone it for now".

Economists call this opportunity cost: the value of what you give up by choosing another path. In disease control, the opportunity cost of not having a mosquito sprayer is the chance to break the transmission cycle sooner, the chance to prevent the next case, and the chance to show residents that their local government is ready to protect them.

A second reason is that this cost is irregular. In a quiet year, borrowing works fine and the old system seems adequate. But an outbreak year is precisely when every office needs its machine at the same moment, which is exactly when a borrowing system breaks down. A system that depends on others tends to fail on the day you need it most.

What leaders need is not someone else's number but a framework that asks the right questions, filled with local data that already exists inside the organisation.

The 5-layer framework: the full cost of doing nothing

Layer 1: Public health

The Aedes mosquito transmits dengue, chikungunya and Zika, and Anopheles mosquitoes carry malaria in some areas. Dengue usually begins with high fever, headache and muscle pain; some patients develop small bleeding spots on the skin, and some can progress to shock without timely care. Children, older people, pregnant women and people with chronic illness need extra protection.

When a case is reported, widely used practice is to spray against adult mosquitoes around the patient's home within roughly a 100-metre radius, together with removing breeding sites under the "3 Keep, Prevent 3 Diseases" measures promoted by Thailand's Department of Disease Control. The key is speed. Mosquitoes that have already picked up the virus can keep passing it on. Every day spent waiting for a machine is a day the risk stays open.

Question for your team: last year, how many days on average passed between a case notification and the actual spraying, and how often was the delay caused by not having a machine?

Layer 2: Time and timing

Thermal fogging and ULV spraying work best when mosquitoes are active, in the early morning and the evening, and they must be repeated on the schedule your health team sets. One round only kills the adults present at that moment while larvae in containers keep developing. An office that borrows equipment cannot set its own timing. It sprays when the owner's machine is free, which may not match the right hours, and it may manage the first round but miss the repeat.

Question: did we complete every planned repeat round, and how many times did we postpone because the machine was unavailable?

Layer 3: Hidden budget leakage

Not buying a machine does not mean spending nothing. Money still leaks out in ways that never add up in one budget line: per-round contractor fees, fuel for picking up and returning borrowed machines, repeated repairs on an ageing unit, overtime for staff waiting late for a machine, and emergency campaign costs when an outbreak grows larger than it should have.

Leaders do not need precise figures. Ask the finance and public health divisions to pull past disbursements related to mosquito control into a single table. The picture usually shows that the money you thought you were saving was already being spent in other forms, with no equipment left on the asset register at the end.

Layer 4: Public trust

Every resident now carries a smartphone. A delay of a few days becomes a community post almost instantly. Residents do not judge the background reasons for a busy machine; they judge what they see: "my child is sick and nobody has come". Trust lost this way is hard to rebuild, and it affects cooperation in other programmes too, such as asking households to remove mosquito breeding sites.

Layer 5: Governance and accountability

Preventing and controlling communicable disease is one of the responsibilities of local government. When an outbreak happens and the response is slow, questions from the local council, supervising agencies and local media follow. "We were waiting to borrow a machine" sounds unprepared. An office with a plan, its own equipment, spraying records and trained staff can explain its actions with confidence and in an auditable way.

Self-assessment table: where to find the data for each layer

No invented numbers: every cell uses your own records, ready to quote in a council memo.

Why the usual fixes fall short in the long run

Borrowing from another office reflects good neighbourly spirit, but it has a built-in limit: the owner will always use the machine for its own area first, and the time you need it is usually the time they need it too. You also do not know the machine's maintenance history, whether it suits your chemical, or whether your team knows how to run it.

Contracting per round is useful for occasional large-area work, but as the main approach it gives you little control over timing and quality. Contractors may juggle several clients during an outbreak, and when the contract ends you are left with neither equipment nor skills.

Running old, unreliable machines means repeated repair bills. A unit that is hard to start or sprays unevenly may also produce the wrong droplet size. Droplets that are too large fall to the ground before they meet a mosquito; droplets that drift away too fast may not work either. Chemical is wasted without full effect.

Buying cheap, non-standard equipment looks economical on purchase day, but often comes with no spare parts, no service centre and no one to train your staff. When it breaks mid-season, you are back to having no machine, and the budget is already spent.

Spraying at the wrong time, such as midday because the borrowed machine was free then, sharply reduces effectiveness.

Comparing four options: borrow, contract, buy, or share

This table does not declare one option best for everyone. It shows the strengths and risks of each, so leaders can combine them to fit local conditions.

Many areas find the right answer is a mix: own what you use often, and contract or share what you use rarely. For example, keep a thermal fogger or backpack ULV unit for individual case response, and work with a larger agency when a wide area needs covering.

8-point checklist: is it time to own a mosquito fogger?

Ask the health team and the chief administrator to answer together. If three or more answers are "yes", seriously consider adding the equipment to your plan.

• ☐ We have had dengue cases for several years, or cases keep returning to the same communities.
• ☐ We have waited for a borrowed machine or a contractor longer than our health team considers acceptable.
• ☐ We have missed planned repeat rounds because a machine was busy or broken.
• ☐ We have schools, child development centres, markets or temples where many people gather.
• ☐ We have received complaints or social media posts about mosquitoes and spraying.
• ☐ Contractor fees, repairs and other hidden spraying costs occur every year.
• ☐ We have staff ready to take responsibility for caring for the equipment.
• ☐ Our disease prevention plan does not yet name equipment that is ready to use immediately.

The solution: choose the right machine from one government equipment hub

Once leaders decide to own equipment, the next question is which type. A common mistake is buying whatever was seen before without looking at the real job. The World Health Disinfection (WHD) government mosquito and insect control equipment hub lets you compare several categories on one page. First, three quick definitions:

• Thermal fogging machine: uses heat to turn the solution into a visible fog that drifts widely; well suited to outdoor areas.
• ULV (Ultra Low Volume): sprays a very small volume of liquid as fine droplets without heat, which makes it suitable indoors.
• Micron: a unit of droplet size; one micron is one thousandth of a millimetre. The right size stays airborne long enough to contact mosquitoes.

Every model from WHD is backed by the company's ISO and GMP quality systems, 100% quality control before delivery, after-sales service, technicians and spare parts, and documentation aligned with Thai government equipment standards. That is what turns an office from "waiting to borrow" into "ready to go", whether it needs a routine mosquito sprayer or equipment for wider insect control in public spaces.

What leaders gain when they stop waiting and start acting

• Citizen trust: the team responds quickly in line with disease control guidance, and residents see tangible action.
• Fewer complaints: with a plan and equipment in place, "why hasn't anyone come?" always has an answer.
• Visible results: spraying records, photos and reports can be presented to the council and in annual reports.
• Budget used wisely: scattered hidden costs become an asset the organisation owns.
• An audit-ready purchase: justification based on real data, specifications that can be referenced, and complete documents for auditors.

For the public health team: technical points to include in your memo

• Describe target areas clearly: outdoors, indoors, and places vehicles cannot reach, so the right machine type is chosen.
• Explain how a thermal fogging machine and a ULV cold fogger differ, and why you may need more than one type.
• Attach a spraying plan that follows Department of Disease Control practice, such as roughly 100-metre radius spraying around cases, repeat rounds, and early-morning or evening timing.
• Name the chemicals you use and confirm the proposed machine supports them; the AT35, for example, handles both water- and oil-based formulations.
• Plan personal protective equipment, operator training and after-use maintenance.
• Always stress that spraying is a supporting measure that must go hand in hand with removing Aedes breeding sites.

10 reasons owning your own mosquito fogger cuts the cost of inaction

1. Respond on the day of notification, without a borrowing queue, shortening the window in which Aedes mosquitoes can spread the virus.
2. Spray at the most effective hours, early morning and evening, not whenever a machine happens to be free.
3. Complete every repeat round your health team schedules.
4. Know each machine's history: when it was serviced, which chemical it used, how it has performed.
5. Build lasting team skills on the same model rather than starting from scratch with every loan.
6. Get the right droplet size, for instance with the AIROFOG U260 ULV cold fogger producing 15 to 30 micron droplets for indoor work.
7. Turn scattered costs into an asset that appears on your equipment register.
8. Serve several missions, not only dengue but broader insect control in public areas your office manages.
9. Help your neighbours: you become the lender rather than the borrower, strengthening the local vector control network.
10. Have after-sales support when you buy through the WHD government equipment hub, with technicians and spare parts ready.

Before and after: from waiting to ready

Procurement tips once the decision is made

1. Build the justification from the 5-layer table. Use the data your team collected rather than a generic line such as "for disease prevention". A request grounded in local records is clearer and easier to audit.

2. Include it in the plan and budget it as equipment. Ask your procurement officer and finance division to confirm how the project must appear in the local development plan and which equipment budget category applies under current rules.

3. Write specifications from the job, not a brand. Describe functional needs: spraying method, supported chemical formulations, body material, droplet size range, power source and after-sales conditions, so that competition stays fair.

4. Set delivery and training conditions, such as a demonstration, operator training, a Thai-language manual, warranty period and a technician contact channel.

5. Plan recurring costs: chemicals, personal protective equipment, fuel for engine-driven units and routine maintenance, so the machine stays ready throughout its service life.

Example field perspective

"Every time we had a case, the first half-day went on phoning around for a machine instead of planning the spraying. When we presented our leaders with a cost table built from our own records, including how often we borrowed, how long we waited and how the costs were spread across different lines, they saw immediately that we had not been saving as much as we thought. Now that we have our own equipment, we can spray at dawn as planned, and sometimes we even help the office next door."

Note: this is a composite example based on typical work of local public health officers, not a quote from any specific person or agency.

Frequently asked questions

Q: If cases are low this year, do we still need to buy?
A: Look at the trend over several years, not one. If cases recur or you have dense vulnerable groups, a quiet year is the best time to prepare equipment and train staff before a bad year arrives.

Q: This article has no cost figures. How do we present to the council?
A: Your own data is the most credible figure you have. Use the 5-layer table to collect records from the health promoting hospital, the finance division and field logs, then compare them with real quotations from suppliers.

Q: Which machine type should we start with?
A: It depends on your main job. If you mainly spray outdoors around cases, a thermal fogger is a common starting point. If you have many schools and public buildings, consider a ULV cold fogger as well.

Q: Can spraying alone stop dengue?
A: No. Spraying reduces adult mosquitoes and lowers transmission risk, but it must be combined with breeding site removal, public education and disease surveillance.

Q: How can WHD help during procurement?
A: With specifications, supporting documents, quotations, demonstrations and operator training, plus after-sales service and spare parts.
