How Long Does a Livestock Mosquito Coil Burn?
How long does one livestock mosquito coil burn, and how much area does it cover? This is the key question when farms purchase and place coils. Burn time decides whether one stick can cover a full night, and coverage decides how many sticks a pen needs. MUWEISHI livestock coils come in two specs-the 1.2m long and the 45cm short-with clearly different burn times and coverage. This article compares burn time, coverage, stick-count methods, and influencing factors to help farms purchase and place precisely. For type choice, see How to Choose Livestock Mosquito Coil Types.
1. Burn Time Comparison
The burn-time difference between the two specs comes mainly from length and stick loading:
| Spec | Burn time per stick | Packaging | Suitable period |
|---|---|---|---|
| 1.2m long | About 8-10 hours | 400 sticks per case | Overnight protection (evening to dawn) |
| 45cm short | About 3-4 hours | Configurable on demand | Short top-up (afternoon, early evening) |
The long type's 8-10 hour burn exactly covers the night peak of mosquito and fly activity (generally evening to early morning)-one stick provides full overnight protection with no mid-night relight. The short type's 3-4 hours suits short daytime fly repellency or building concentration in the early evening to hand off to a long stick.
Note that burn time is an approximate value affected by humidity, ventilation, and placement-damp or windy conditions may shorten it slightly. Both types burn stably with a high ignition point, ensuring continuous release through the effective period.
2. Coverage Area Comparison
Coverage determines how many sticks a pen needs:
| Spec | Coverage per stick | Typical scenario |
|---|---|---|
| 1.2m long | About 60-80 sqm | Large pens, open farms |
| 45cm short | About 20-30 sqm | Small pens, nursery boxes, temporary spaces |
Take a pig farm: a standard fattening pen of about 60-80 sqm is covered by one long stick; a farrowing pen or nursery box of about 20-30 sqm needs one short stick. For long, narrow spaces like poultry aisles or cattle/sheep walkways, place one long stick every 60-80 sqm along the aisle.
Area is an "effective coverage" concept-building effective concentration in the mosquito and fly activity zone. Open, well-ventilated spaces hold concentration less easily, so actual coverage trends toward the lower end; enclosed small spaces trend toward the upper end.
3. How to Count Sticks by Area
When purchasing and placing, calculate dosage as follows:
- Measure pen area: Length x width gives single-pen area; multiply by pen count for total area.
- Convert to stick count by spec:
- Long: total area / 70 sqm (midpoint of 60-80 sqm) = sticks needed
- Short: total area / 25 sqm (midpoint of 20-30 sqm) = sticks needed
- Ventilation and density correction: For open, well-ventilated, high-density sites, convert at a 0.8x area factor (i.e., add sticks); for enclosed small spaces, use the upper end.
- Overnight dosage estimate: One long stick burns 8-10 hours, covering the night in one go; short sticks need 2-3 in relay to cover a full night.
Example: a 200 sqm open fattening pig pen needs 200 / 70 = about 3 long sticks; with open-air 0.8x correction, about 3-4 long sticks for overnight protection. For more placement methods, see How to Kill Mosquitoes Effectively in a Farm.
4. Factors Affecting Burning and Effect
Burn time and coverage are not fixed. They are affected by:
- Ambient humidity: In hot, humid conditions, coils absorb moisture easily, burn incompletely, and shorten burn time-always seal after opening to prevent moisture.
- Ventilation: Open or semi-open pens have strong airflow, making effective concentration harder to maintain-coverage trends to the lower end.
- Placement: Place on dry ground after lighting-damp ground undermines burning stability. Do not use in strong wind or under fans.
- Mosquito and fly density: At very high density, a single stick's coverage is "diluted," requiring more sticks or the strong type.
- Type choice: Standard, wormwood, and strong types share the same burn time and coverage; the difference is active-ingredient concentration and release intensity. For high-density scenarios choose the strong type; for pregnant and young animals choose the wormwood type.

How long one livestock mosquito coil burns and how much area it covers, in short: the 1.2m long type burns about 8-10 hours per stick and covers about 60-80 sqm, suited to large-area overnight protection; the 45cm short type burns about 3-4 hours per stick and covers about 20-30 sqm, suited to small spaces and short top-ups. Purchase by stick count against area, correcting for ventilation and density. As a source factory, MUWEISHI supplies both specs in full at factory-direct prices.
