The dengue mosquito does not fly far. It is born, grows and bites within a radius of a few meters — almost always in your own backyard, or your neighbor's. That is why fighting dengue is not the city hall's job alone. It is the work of people who know the street. And few groups know a neighborhood better than a Pathfinder Club on the march.
A well-run drive is not about going out spreading poison. It is the opposite: it is patient searching, breeding site by breeding site, house by house, covering, tipping over and drying out every pot of standing water. It is a chat at the gate. It is a leaflet in hand. It is walking alongside the health agent. And, for the Pathfinder, it is also an act of faith with the hands.
This guide is for the Director who wants to set up the drive, for the Counselor who will lead the Unit on the street, and for the father or mother who needs to know their child will be safe. You will find the plan for a whole Saturday, the list of materials, the non-negotiable safety rules, and the signs that turn an ordinary fever into a rush to emergency care.
Why the Club makes a difference here
Dengue is a neighborhood disease. The Aedes aegypti reproduces in standing, clean water, inside and around homes, and flies short distances. That means one hard truth: the breeding site that sickens a family is almost always on their lot or the one next door. Fighting it, therefore, belongs to those who live there — and the Club is made of people who live there.
A Club has what the official campaign needs most and manages least: legs, eyes and trust. Dozens of teenagers and adults willing to walk the whole street on a Saturday morning. Eyes trained to search, because a Pathfinder already knows how to observe nature. And the trust of the uniform: many people who won't open the gate to a stranger will open it for the kid in the scarf who studies with their child at school.
Add to that the discipline of the Club. A Unit knows how to move together, follow instructions and not scatter. A disorganized drive turns into dangerous chaos; a drive with Units, Counselors and meeting points turns into an operation. You are not improvising a social action — you are applying, in the neighborhood, the same order you train at the meeting.
And there is the layer only the Pathfinder sees. Serving the community is not an activity parallel to faith: it is faith in motion. When Jesus summed up the Law, he set the love of God and the love of neighbor side by side: "Love your neighbor as yourself. There is no commandment greater than these" (Mark 12:31, NIV). Eliminating a neighbor's breeding site is loving that neighbor with wet hands.
Where the mosquito hides: hunting breeding sites
Before heading out, your Unit needs to know exactly what to look for. The mosquito does not lay eggs just anywhere — it wants standing water, even if it is only a bottle cap. Train the Pathfinders' eyes on the usual suspects, the ones that show up in almost every backyard.
| Breeding site | What to do |
|---|---|
| Old tires | Puncture, store under cover or discard. A tire holds water for months. |
| Clogged gutters | Clear leaves and debris so the water drains. |
| Plant pot saucers | Remove them or fill with sand to the rim. |
| Bottles, cans, pots | Turn them mouth-down or collect them in the trash sweep. |
| Water tanks and drums | Seal them tightly with a lid. Treated water, but uncovered, still breeds mosquitoes. |
| Drains and trays | Refrigerator and air-conditioner trays; seldom-used drains, screen or cover them. |
Teach the golden rule in three words: tip, cover and dry. Anything that holds water and can be tipped over, gets tipped. Anything that must store water, gets a firm lid. Anything left over, dries in the sun. It is not about killing the adult mosquito already in flight — it is about ending the nursery before it is born.
Agree on a simple signal between pairs, too: each eliminated breeding site becomes a check mark on the block map the Unit received. By the end of the morning, that map shows the community — and the health agent — the real size of the work done. A concrete number convinces more than a speech.
Safety first: what each age can and cannot do
Here is the non-negotiable part. A drive of minors only exists with an adult nearby and with clear limits. A teenager's task is to search, empty clean water and report — never to handle chemical products. Larvicide, when it comes into play, is the responsibility of the health agent or a trained adult, never of a 12-year-old Pathfinder.
Why? Because larvicide and insecticide are public-health products that require the right dose and correct handling. Putting them in a minor's hands is creating a new risk to fight another. The Club's memo is simple: standing water, the Pathfinder empties; poison, the qualified adult applies. No exceptions.
Protective gear is also the law. Everyone on the street with: gloves to handle trash and containers; long trousers and long-sleeved shirt; a cap or hat; repellent applied before leaving; closed shoes, never flip-flops. Bring drinking water for the Club itself — a sunny drive is a dehydrating drive. And no one enters a backyard or lot without the resident's permission.
Set up the operation by Units, each with its responsible Counselor and a fixed meeting point. No one walks alone: pairs or trios, always. If a Pathfinder finds something dangerous — an exposed wire, a loose dog, heavy debris, a hostile resident — the order is one: pull back and call the adult. The drive ends with everyone counted at the starting point.

Half the drive is cleaning. The other half is people talking with people. There is no point emptying a breeding site today if the resident fills it again on Tuesday. That is why the leaflet and the conversation are worth as much as the broom.
Prepare a simple leaflet, on one side only, with three blocks: where the mosquito is born (the list of breeding sites), what to do every week (the 10-minute inspection of your own backyard) and when to see a doctor (the warning signs, further on). Put the phone number of the neighborhood health clinic and your local emergency number. No long text: a leaflet no one reads saves no one.
Rehearse the approach beforehand. The Pathfinder introduces themselves, says the Club is running a dengue drive with the health clinic and asks if they may take a quick look at standing-water points in the backyard. Courtesy opens gates. If the resident declines, thank them, hand over the leaflet and move on. Service is offered, never imposed.
Record what you find. One sheet per block, marking houses visited, breeding sites eliminated and closed houses for a second pass. That record is gold for the health agent and shows the Club's leadership that the work was real. It is also a lesson in citizenship: the Pathfinder sees, in practice, how a community takes care of itself.
Partnering with the health clinic and the health agent
Never run a dengue drive alone. Before setting the date, the Director reaches out to the neighborhood's primary health clinic and talks with the region's community health agent. That professional knows the hot spots, knows where there have been recent cases and can guide — or apply — larvicide where needed.
This partnership raises the level of the work. The health agent brings the technical information; the Club brings the labor and the reach. Together, you cover an area neither would cover alone. Many city governments have official campaigns against Aedes and welcome with open arms an organized group willing to help — ask, and you may get leaflets, gloves and even trash bags.
Align roles clearly. The Club searches, empties clean water, hands out leaflets and collects trash. The health agent or the qualified adult handles any chemical product and advises on suspected cases. That way no one does what they shouldn't, and the operation gains official backing — which also protects the Club.
Add the trash sweep, too. Arrange with the city's sanitation service a day to collect the debris the drive will gather: tires, old furniture, bottles. It is no use piling everything on the sidewalk and leaving — abandoned debris becomes a new breeding site. This kind of action pairs well with the community service the Club already practices and with the work of ADRA alongside the Club.
Dengue, zika or chikungunya? And the warning signs
The three viruses come from the same mosquito, the Aedes aegypti, but manifest in different ways. Knowing how to tell them apart helps guide the community — without turning into a diagnosis, which is always the doctor's task. According to Fiocruz, the basic difference is this: dengue usually brings high fever, headache, pain behind the eyes and a lot of body ache; zika brings low or no fever, with red spots on the skin and intense itching; chikungunya is marked by strong joint pain — hands, feet, wrists and ankles — that can last for weeks.
Dengue is the most worrying, because it can progress to a severe form. The danger lies in a treacherous detail: the critical phase usually begins when the fever drops, between the third and seventh day. The person thinks they have gotten better — and that is precisely when the warning signs may appear. That is why no one clears themselves alone.
According to the Ministry of Health, these are the warning signs that demand immediate care: intense and continuous abdominal pain; persistent vomiting; bleeding from mucous membranes (nose, gums); dizziness or a drop in blood pressure; drowsiness or unusual irritability; fluid accumulation. Faced with any of them, do not wait: seek help at once.
Engrave the rule the Club should repeat at every house: fever with strong belly pain, non-stop vomiting or any bleeding is an emergency. Call your local emergency number (in Brazil, SAMU 192) or take the person to the nearest health service immediately. Drinking plenty of fluids from the first day of fever helps, but does not replace the doctor. This block is awareness — dengue is treated by a health professional.
A Saturday plan: materials and step by step
A drive fits into one well-organized morning. Here is a plan the Director can adapt to the size of the Club and the area. The week before is as important as the day itself: without preparation, Saturday turns into confusion.
During the week: talk with the health clinic and the health agent; choose the area and divide it into blocks; print the leaflets and the record sheets; notify the parents in writing, with time and meeting point; set aside gloves, trash bags, drinking water, repellent and a first-aid kit; arrange the trash sweep with the city.
On Saturday: 7:30 a.m. — gathering, prayer and dividing the Units by block, each with its Counselor. 8:00 a.m. — quick review of the safety rules and of what to look for. 8:15 a.m. — heading out in pairs, house to house: searching, emptying, advising, handing out leaflets, recording on the sheet. 10:00 a.m. — collecting the trash at the agreed points for the sweep. 10:30 a.m. — everyone back at the meeting point, headcount, snack and hydration. 11:00 a.m. — closing circle: each Unit tells how many breeding sites it eliminated and how many houses it visited, a closing prayer and thanks to the community.
Close the cycle afterward. Gather the numbers, send a short report back to the health clinic and put a second pass at the closed houses on the calendar. The mosquito returns with every rain; that is why the best drive is not the only one — it is the one that becomes a habit on the Club's calendar. Caring for the body and for one's neighbor, after all, is a Christian understanding: "Do you not know that your bodies are temples of the Holy Spirit, who is in you [...] and that you are not your own?" (1 Corinthians 6:19, NIV).
