Thermal Fogging Machine Meets Old Tires and Illegal Dump Sites: Municipal Aedes Breeding Grounds That Need Source Clean-Up Alongside Fogging With the AIROFOG AT35

One old tire left behind a tire-repair shop looks harmless. After rain, though, it becomes a shaded, warm Aedes nursery that is hard to empty. Add a vacant lot that the neighbourhood has turned into a dump, and a municipality has a mosquito factory that fogging alone cannot shut down. This guide helps executives and public health divisions tackle old tires and dump sites systematically, and use a thermal fogging machine at the right moment and safely.

1-minute summary

• The problem: Old tires trap rainwater in their dark inner curve, where it is hard to pour out. Dump sites hold bottles, foam boxes, buckets and broken containers. Both are prime Aedes breeding sites in municipal areas.
• The impact: Repeated dengue cases around tire shops, garages and vacant lots, rising complaints, and fogging budgets spent again and again without breaking the cycle.
• The principle: Remove the source: collect, transport, dispose of or modify tires so they cannot hold water, and close dump sites, while fogging reduces adult mosquitoes in high-risk areas.
• Why the AT35: The AIROFOG AT35 is a 100% stainless steel, lightweight thermal fogger that works with water-based and oil-based chemicals and is certified in Germany and the UK. Its fog penetrates vegetation and gaps in piled material, and the spray line is clearly visible.

The tire pile behind the repair shop that nobody counted

(Illustrative scenario) Somsak directs the public health and environment division of a town municipality crossed by a major highway. Both sides of the road are lined with tire-repair shops, garages and used-tire dealers. Behind the market sits a large vacant plot whose owner has not visited in years. It has become the place where neighbours dump old sofas, rubbish bags, foam boxes and tires at night.

That rainy season, the disease control team logged dengue cases in the same community week after week. Each time, they fogged around patients' homes as the guidelines required. Mosquitoes dropped for a few days and then returned. Finally, one officer cut across the vacant lot and flipped a tire. Black water poured out with hundreds of larvae. A wider survey found dozens more tires in the same state, both on the vacant lot and behind two or three shops that stored old tires in the open while waiting for buyers.

Somsak knew immediately that fogging alone was chasing symptoms. The next questions were harder. The tires belonged to businesses. The land was private. Collection needed trucks and labour. And where would the tires go? Old tires and dump sites are not a job for the public health division alone. They need the engineering division, the cleansing section, the legal officer and the cooperation of local business owners.

Why old tires are such effective Aedes breeding sites

• Shape that traps water: the inner curve holds rain whether the tire lies flat or stands upright, and emptying it completely is difficult.
• Dark and warm: black rubber absorbs heat and the interior is shaded, ideal for egg-laying and larval growth.
• Built-in larval food: leaves and dust that fall inside become organic matter larvae feed on.
• Drought-resistant eggs: Aedes eggs stuck to the inner wall can survive dry conditions for months and hatch as soon as rain returns. A dry-looking tire is not a safe tire.
• Mosquitoes travel with tires: moving used tires between areas can carry eggs too, a pathway that has been reported as contributing to the spread of some Aedes species to new regions in several countries.
• Invisible from outside: larvae sit in the inner curve, so staff who do not tip the tire never see them.

Dump sites offer an even wider range of containers: plastic bottles, cans, foam boxes, paint buckets, old appliances, crumpled bags that form puddles and sagging tarpaulins. Combined with long grass and shrubs where adult mosquitoes rest, these places both produce larvae and hide adults. Dumps also attract rats, flies and cockroaches, create bad smells, and tire piles carry a fire risk that releases toxic smoke.

The impacts municipal executives must weigh

1. Public health

Aedes mosquitoes transmit dengue, chikungunya and Zika. Dengue starts with a persistent high fever, headache and body aches, sometimes with skin bleeds, and the period as fever falls is when shock must be watched for. Chikungunya brings severe joint pain that can become long-lasting. Zika is a concern for pregnant women. Communities around tire shops and garages include business families, employees and children playing nearby, and older people and those with chronic illness in the same neighbourhood are just as exposed.

2. Budget leaking out of sight

While breeding sites remain, teams fog the same area repeatedly. Chemicals, fuel, overtime and machine repairs add up, and results never last. Over time these costs exceed a one-off investment to collect tires and permanently close dump sites.

3. The town's image

Tire and rubbish piles along the main road are the first thing visitors see. They signal a neglected town, and once photographed for social media, questions go straight to the mayor. Conversely, a well-run tire collection programme with visible results becomes an achievement residents can see and touch.

4. Complaints and community conflict

Neighbours of tire shops may complain about mosquitoes, smells and safety. Shop owners may feel accused. If the municipality steps in without a clear and fair approach, conflict escalates. Offering businesses practical options, such as a collection point or proper storage guidance, reduces resistance considerably.

5. Staff workload

Collecting tires and rubbish is heavy work requiring trucks, labour and protective equipment. Fogging around piled material requires a reliable machine and staff who understand safety. If the machine breaks down mid-job, or divisions do not plan together, staff tire out with nothing to show for it and morale falls.

Why the usual approaches fail

1. Fogging without clearing: thermal fogging cuts adult mosquitoes temporarily, but larvae in the tires remain and a new generation soon replaces them.
2. One-day campaigns: a clean-up day helps on the day, but without an ongoing tire collection system and dump-site monitoring, tires and rubbish return within weeks.
3. Nowhere to take collected tires: without a clear disposal route, collected tires may end up piled in the municipality's own yard, creating a new breeding site.
4. Wrong time, wrong technique: fogging in bright midday sun or strong wind lets fog rise and scatter quickly, while early morning and evening, when Aedes are active, go unused.
5. Machines not ready: old foggers with corroded bodies, hard starting or no spare parts often fail right in the outbreak.
6. Cheap, non-standard equipment: machines without certification or after-sales service can give uneven fog and pose risks to operators.
7. Not using legal and cooperative tools: if landowners and businesses are not notified within the municipality's existing powers, the whole burden falls on the municipality again and again.

A five-step plan for old tires and dump sites

Step 1: Map the risk points

Survey and pin tire-repair shops, used-tire dealers, garages, scrap yards and vacant lots used as dumps. Record approximate tire numbers, storage conditions and larval findings. Use the map to plan collection, plan fogging and report to executives.

Step 2: Work with businesses

Hold a meeting with tire shops and garages. Explain the risk and ask them to store old tires under a roof, pull tarpaulins tight so they do not pool water, drill drainage holes in unused tires or stand them so water cannot collect, and hand old tires regularly to legitimate buyers or disposal operators. A "larva-free shop" sign or certificate for cooperating businesses creates positive motivation.

Step 3: Set up tire drop-off points and collection rounds

Schedule regular tire collection from households and shops, for example monthly during the rainy season. Provide a roofed holding area checked weekly for larvae, then pass tires on to agencies or businesses that recycle or dispose of them properly. Residents who reuse tires as planters or garden edging should always fill them completely with soil or drill drainage holes.

Step 4: Close dump sites for good

After clearing, cut the grass, level puddle-forming ground, install no-dumping signs with a reporting channel, and ask landowners to fence or maintain the land within the municipality's powers. Offer a proper bulky-waste drop-off so residents have an alternative. If people have nowhere to take old appliances or tires, illegal dumps will always reappear.

Step 5: Fog with a purpose

Use the thermal fogging machine where there are cases or dense adult mosquitoes: within 100 metres of patients' homes, along vegetation around vacant lots and around tire holding areas. Fog in the early morning or evening when mosquitoes are active, and coordinate with collection days to reduce adults left in the area. This combines the Department of Disease Control's "3 Keeps to prevent 3 diseases" (keep homes tidy, keep rubbish collected, keep water managed) with adult mosquito control.

Measuring success

Track a few simple indicators each month: the number of tires collected, the number of dump sites closed and still closed, larval findings at mapped risk points, complaints received, and new dengue cases in the target communities. Share the results with the council and with cooperating businesses. Visible progress keeps shop owners engaged, justifies next year's budget and helps the team see that fewer, better-targeted fogging rounds are delivering more than frequent routine fogging ever did.

The equipment answer: AIROFOG AT35, a stainless steel thermal fogger for municipal field work

The AIROFOG AT35 is a thermal fogging machine (a unit that uses heat to turn the formulation into a fine, visible fog) supplied by World Health Disinfection (WHD). According to the product information:

Thermal fog excels here because it drifts into shrubs, long grass and gaps between piled material where adult mosquitoes rest. The visible fog lets staff check coverage instantly and shows residents that the agency is on the ground. WHD operates under ISO and GMP, runs 100% quality control before delivery, and provides after-sales service, technicians and parts, meeting Thai standards for government mosquito control equipment.

How to fog around tire shops and dump sites effectively and safely

1. Survey first: walk the site beforehand, noting tire piles, dry rubbish, fuel drums, power cables and adjoining homes, to set the walking line and safe distances.
2. Notify businesses and residents: ask shops to put away goods and food, close doors and windows, and move pets away from the fogging line.
3. Fog when mosquitoes are active: early morning or evening, with calm air and no rain, so fog stays low and lingers long enough to contact mosquitoes.
4. Target resting sites: focus on shrubs, long grass, under eaves and fence lines around vacant lots. Walk slowly and steadily without pausing in one spot.
5. Keep clear of flammables: never direct the nozzle into tires, rubbish or dry grass, as the manual advises, and have a helper carry an extinguisher.
6. Manage traffic: near roads, post someone to warn drivers, because fog obscures visibility.
7. Check larvae afterwards: follow up the next week, record larval indices and adjust the plan.

Good fogging is not measured by how much smoke you see. It is measured by fogging the right place, at the right time, with the right product, alongside source removal. When those pieces come together, the number of fogging rounds needed each season tends to fall, saving chemicals and staff time.

10 reasons the AIROFOG AT35 suits Aedes control around old tires and dump sites

Before and after: source clean-up plus fogging

Procurement tips: budget for both tools and system

Solving old tire and dump-site problems takes several budget items, not only a sprayer. Treat it as one programme, then split lines according to your agency's rules.

A thermal fogger belongs in the equipment budget. Build the justification from real data: the number of tire shops and dump sites on your risk map, past case data and complaint counts. Always confirm steps with your procurement officer, since details differ by agency. If the budget allows, consider a vehicle-mounted ULV sprayer for roadside work alongside a handheld thermal fogger for places vehicles cannot reach. Good vector control depends on both matching the tool to the terrain and keeping the programme running year-round.

Example field perspective

(A composite example based on common field experience, not a quote from a real person.)

"We used to fog the community behind the market almost every week. Residents said they smelled chemicals every evening but the mosquitoes were still there. When we switched to mapping tire shops and vacant plots, and held a big tire collection day with the engineering division, the picture changed. Most shops cooperated because we were not there to catch them out; we came to help them find somewhere to send their tires. On collection day we fogged along the shrub lines too. The stainless steel machine is light enough to carry comfortably. The one rule our team repeats is never to point the machine into a tire pile, because it runs hot. We rehearse safety every time. Since then we fog less often, but with better results."

Frequently asked questions

Q: Is the fog a concern for people living next to the site?
A: Any insecticide application should be done with care. Use registered products at label rates, notify residents in advance, ask them to close doors and windows and keep children, pets and food away from the fogging line, and let the fog settle before people return to the area. Staff should wear appropriate protective equipment every time.

Q: Can a dry-looking tire still breed Aedes?
A: Yes. Aedes eggs can cling to the inner wall in dry conditions for a long time and hatch as soon as rainwater collects. Tires must be made unable to hold water, not left until larvae appear.

Q: Can we fog directly into a tire pile?
A: Not recommended. A thermal fogger works with heat, and pointing the nozzle into tires or dry rubbish at close range is a fire risk. Fog along the surrounding vegetation at safe distances per the manual, and deal with the tires by collection or modification.

Q: Should we fog before or after tire collection day?
A: Where there are cases or heavy mosquito activity, fogging around the same time as collection helps reduce adults left in the area. Follow your local disease control guidance and the day's weather.

Q: Can residents reuse tires as planters?
A: Yes, provided they are filled completely with soil or drilled for drainage, leaving no curve that can hold water.

Q: What chemicals can the AT35 use?
A: The AT35 handles water-based and oil-based formulations. Use only properly registered mosquito control products according to the label. For advice, contact WHD on 065-556-6294.

Q: How can a small municipality with few trucks begin?
A: Map and rank risk points, start with communities that have cases, ask tire shops to store tires properly, and expand collection rounds as capacity allows.
