Mosquito coils, mosquito sprays and liquid vaporisers: every monsoon season Mumbai households panic-buy these products to combat seasonal vector-borne diseases. It’s something we’ve all done for years without thinking twice about it. But are these stop-gap solutions really – and I mean really – as effective/safe as investing in good mosquito nets in Andheri just once? Compare the two side-by-side and you’ll realise the answer is much simpler than you think.

Understanding the Mosquito-Borne Disease Risk in Mumbai

The cases of dengue and malaria surge every monsoon season in Mumbai because of water-logging, humidity and overcrowding. Dengue causing Aedes mosquito bite mostly during daytime whereas malaria causing Anopheles mosquitoes bite during dusk and dawn. This means that you need almost 24×7 protection from mosquitoes – something that chemical repellents which fade away with time or require re-application cannot guarantee.

The Real Cost of Repellents

The average family spends a small fortune each month buying coils, sprays, and refill packs during mosquito season. Usually that’s June through October in Mumbai. But recently, with increasingly unpredictable monsoons, mosquitoes can be an even bigger problem. After several years, that monthly expense can easily surpass the one-time installation fee you pay for mosquito nets in Andheri. And nets are a one time expense. Repellents must be bought again… and again… every season, forever.

Health Concerns with Chemical Repellents

• Mosquito coils emit PM inside bedrooms at concentrations similar to what health scientists have found with secondhand smoke exposure.
• Liquid vaporizers contain synthetic pyrethroids which can cause respiratory irritation after extended, nightly exposures – extremely troubling for kids, elderly relatives, or anyone with asthma/allergies.
• Sprays should never be used without ventilating the room and aren’t thought to be safe for prolonged bedroom use with closed windows (rainstorm?)
• Nightly low dose chemical exposures that build up over the long term aren’t generally considered when tallying up that nice little “convenience” score.

Mosquito Nets: A Physical, Chemical-Free Barrier

And lastly…nets use no chemicals whatsoever – they work by preventing mosquitoes from entering your home without stopping fresh air or sunlight. This is ideal if you have: 

• Children – young lungs are more sensitive to chemicals in the air
• Seniors – we understand seniors may have less-than-optimal lung function already
• Others who are sensitive to what’s in the air, or who have asthma/allergies
• Pets – chemicals can impact your cat or bird MUCH worse than they can you. They have smaller bodies and metabolize things differently.

Comparing the Two Over 3 Years

Dengue & Malaria Protection Specifically

Dengue transmitting mosquitoes, as well as malaria mosquitoes, tend to be most active at dawn and dusk, and during humid daytime hours depending on conditions. That’s why a properly fitted net provides 24-hour protection – even if you wear off mid-sleep and become vulnerable again, the way chemical protection methods often fail to cover. I’ve spoken to countless families who wake up in the morning covered in mosquito bites even though they had a vaporizer running all night. Once the chamber starts to get low or air flow changes in a room, the level of chemicals decreases.

Choosing the Right Net Type for Disease Protection

• Roll-down or sliding nets for everyday windows and doors leading to balconies.
• Extra fine nets for homes located in high risk pockets. Some mosquito species are small enough to require added filtration.
• Mosquito nets for your entire home. It only takes one open window for mosquitoes to get in.

The Environmental Angle

Apart from the harm they cause to an individual’s body, chemical repellents add to indoor air pollution. In addition, when you consider years of cumulative usage throughout a metropolis the size of Mumbai, there’s a significant environmental impact. Mosquito nets are a one-time physical installation and have zero environmental impact.

Our Recommendation

If you live in mosquito prone areas of Andheri, Vile Parle and Jogeshwari and are looking for a long term solution, net installation is worth every penny. Not only does it pay for itself in 2 seasons but it eliminates the health hazard of spraying chemicals in your home altogether. Consider it an investment into your long term health – not just a luxury.

FAQs (Frequently Asked Questions)

Q1: Do mosquito nets actually stop dengue-carrying mosquitoes?

Yes. A correctly fitted net with fine mesh blocks the Aedes mosquito (the dengue carrier) as effectively as it blocks any other species, since the mesh size is designed to be smaller than any common mosquito.

Q2: How long do mosquito nets last?

Quality pleated and sliding nets typically last 8–10 years with basic care, making them a genuinely long-term investment rather than a recurring cost.

Q3: Are mosquito nets better than electric vaporizers for children’s rooms?

Yes, nets provide a physical barrier without releasing any chemicals into the air your child breathes overnight, which is a meaningful difference for developing respiratory systems.

Q4: Can mosquito nets reduce dependence on coils and sprays completely?

In most homes, yes. Many customers stop using repellents entirely after installation, only occasionally using them when doors are left open for extended periods.

Q5: Is net installation a one-time cost or does it need yearly renewal?

It’s a one-time installation cost. Only cleaning and occasional minor repairs are needed going forward – no recurring purchases required.
