1. Eliminate Standing Water

Mosquitoes lay eggs in stagnant water. So:

• Empty water from buckets, drums, flower pots, tires
• Do not allow water to collect on rooftops
• Change water in plant trays every 2–3 days
• Keep water tanks tightly covered

2. Proper Drainage System

• Clean drains and gutters regularly
• Remove blockages so water flows freely
• Fill pits and low areas where rainwater stays
• Repair leaking pipes and taps

3. Waste Management

• Dispose of plastic cups, bottles, and cans properly
• Do not throw garbage in open areas
• Use covered dustbins
• Keep surroundings clean and dry

4. Water Storage Management

• Cover drums, tanks, and containers
• Do not store water unnecessarily
• Scrub containers weekly to remove mosquito eggs

5. Vegetation & Bush Control

• Cut tall grass and bushes
• Remove unwanted plants near houses
• Keep gardens clean
  Mosquitoes hide in shady, humid places

6. House & Building Practices

• Use window screens and door nets
• Close broken drainage holes
• Fill cracks in walls and floors
• Ensure sunlight and air flow inside rooms

7. Community Participation

• Weekly “Dry Day” (everyone empties water containers)
• Awareness programs
• Joint cleaning drives
• Report clogged drains to authorities

 

8. Animal & Farm Area Control

• Do not allow water to collect near cattle sheds
• Clean poultry and livestock water trays daily
• Maintain dry soil around farms

9.     Benefits of Cultural Control

✔ No poison
✔ Safe for humans and pets
✔ Environment friendly
✔ Long-term solution
✔ Low cost
✔ Reduces disease risk (Dengue, Malaria, Chikungunya)

Biological Control: – Biological control means reducing mosquito larvae and adults by using.

Natural predator’s
✔ Bacteria
✔ Biological products
✔ Living organisms

It is safe for humans, animals, and the environment when used correctly.

1. Larvivorous Fish (Mosquito-eating fish)

These fish eat mosquito larvae in water bodies.

Common species:

• Gambusia (Mosquitofish)
• Guppy (Poecilia reticulata)
• Tilapia (in ponds)

Used in:

• Ponds
• Water tanks
• Drains
• Ditches
• Lakes

✔ Long-lasting
✔ Low cost
✔ Natural method

2. Bacterial Larvicides

Special bacteria kill mosquito larvae only (not harmful to people or pets):

a) Bacillus thuringiensis israelensis (BTI)

• Attacks mosquito larvae gut
• Works in stagnant water
• Very safe and selective

b) Bacillus sphaericus

• Effective in polluted water
• Longer residual effect

Used in:

• Drains
• Water containers
• Ponds
• Construction sites

✔ No harm to fish, birds, or humans
✔ No smell
✔ Environment friendly

3. Predatory Insects & Animals

Natural mosquito enemies:

• Dragonfly nymphs (eat larvae)
• Frogs & tadpoles
• Water beetles
• Spiders (eat adult mosquitoes)

Best for:

• Ponds
• Gardens
• Wetlands

4. Larvivorous Copepods (Tiny crustaceans)

• Small aquatic animals that eat mosquito larvae
• Used in:
  • Wells
  • Water storage tanks
  • Cement tanks

✔ Self-multiplying
✔ Very effective for long term control

5. Fungal Biological Control

Certain fungi infect and kill mosquitoes:

• Metarhizium anisopliae
• Beauveria bassiana

Used as:

• Biopesticide sprays
• Resting-site treatment

✔ Targets mosquitoes
✔ Low environmental impact

6. Sterile Insect Technique (SIT) / Wolbachia Method

Advanced biological method:

• Male mosquitoes are sterilized or infected with Wolbachia bacteria
• Released males mate with females
• Eggs do not hatch

Used in:

• Urban mosquito control programs
• Research & government projects

✔ Reduces mosquito population
✔ No chemicals
✔ Species-specifi

✅    Advantages of Biological Control

✔ Safe for humans & pets
✔ No chemical residue
✔ Environment friendly
✔ Reduces resistance
✔ Sustainable
✔ Works well with cultural control

Mechanical Control:-Mechanical control means preventing mosquito breeding and bites using physical barriers, removal of breeding place, devices and tools.

✔ Physical barriers
✔ Traps
✔ Removal of breeding places
✔ Devices and tools

It is:
✅ Chemical-free
✅ Safe for humans & pets
✅ Environment friendly
✅ Good for homes, schools, hospitals

1.  Source Reduction (Physical Removal of Breeding Sites)

This is the most important mechanical method.

Actions:

• Empty standing water (buckets, tires, flower pots)
• Cover water tanks & drums
• Clean roof gutters
• Fill holes & puddles
• Improve drainage system

Stops:
👉 Egg laying
👉 Larva growth
👉 Adult mosquito formation

2.  Mosquito Nets & Bed Nets

Used to stop mosquito bites during sleep.

Types:

• Normal net
• Window net
• Door net
