Summer’s Here — and So Are the Mosquitoes!

A Simple Way to Stay Safe from Mosquitoes with Ceiling Mosquito Spray

When the warm weather arrives, so do our favorite summer pleasures—barbecues, garden parties, holidays, and open windows. But with the sunshine comes an unwelcome guest: mosquitoes.

You’re just about to fall asleep, and then you hear it—bzzzz—followed by that familiar itchy bump the next morning. For many of us, mosquitoes are one of the most annoying parts of summer.

But why exactly do we dislike them so much? And more importantly, what can we do to keep them out of our homes?

Why Mosquitoes Are More Than Just Annoying

Not Just Itchy—They Can Carry Serious Diseases

Getting bitten by a mosquito is uncomfortable, especially for children or those with sensitive skin. The itching and swelling can last for days.

But more than that, mosquitoes are known carriers of infectious diseases. In various parts of the world, they’re responsible for transmitting:

  • Dengue fever
  • Zika virus
  • West Nile virus
  • Malaria

Even in countries where these diseases are rare, the potential risk has raised awareness around mosquito prevention. In Japan, for instance, a 2014 outbreak of dengue fever in a Tokyo park brought home the reality that mosquito control is not just a comfort issue—it’s a health issue.

A Brief Look at Japan’s Innovative Mosquito Control History

From Incense Coils to High-Tech Sprays

Japan has a long history of battling mosquitoes. One of the most iconic inventions is the mosquito coil, a spiral-shaped incense that slowly burns and repels insects. It’s been used since the late 19th century and is still popular today.

In the 1980s, electric vaporizers became widespread. These plugged-in devices slowly release mosquito repellent into the air, offering all-night protection without fire or smoke.

And now, a new generation of products is making things even easier: aerosol sprays that work with just one push aimed at the ceiling. These are quick, fire-free, and power-free—perfect for modern homes and busy lifestyles.

Let’s take a look at two standout products from Japan that are now gaining attention overseas as well.

Mosquito-Free in One Spray: Two Products to Know

🔹 Earth Corporation: No-mat Spray

This ceiling spray is one of the easiest and most effective ways to get rid of mosquitoes indoors. Just one push toward the ceiling keeps your space protected for up to 12 hours—no need for plugs, flames, or devices.

🌿 Active Ingredient: Pyrethroids

No-mat Spray uses pyrethroids, a group of compounds inspired by the natural insect-repelling ingredients found in chrysanthemums (pyrethrum flowers).
They are highly effective against insects but are quickly broken down and excreted by mammals, making them low in toxicity and generally safe for use around humans.

👶 Safe for Pregnant Women and Babies

Yes—this product is safe for homes with pregnant women or infants.
However, when spraying, make sure no one else is in the room to avoid directly inhaling the mist. After spraying, it’s perfectly fine to enter the room right away.

🐕 Safe for Pets (with Some Exceptions)

It’s safe to use around dogs, cats, hamsters, and birds.
However, do not use near fish tanks, aquariums, or insect cages, as the ingredients may harm aquatic life or delicate insects.

💡 Highlights

  • One push toward the ceiling = 12 hours of mosquito control
  • Odorless option available
  • No electricity or open flames required
  • Approximately 200 uses per can
  • Ideal before bedtime or when heading out
  • Great for travel, cabins, or outdoor stays

🔹 KINCHO: Ceiling Mosquito Spray – 12 Hour Type (https://www.kincho.co.jp/en/products/ka_n_spray_12)

This smart, one-push spray from KINCHO protects your home from mosquitoes for up to 12 hours. Just point it at the ceiling and press once—the fine mist spreads across the ceiling and walls, where mosquitoes like to rest, and kills them on contact.

🔬 The Science Behind the Spray

Traditional mosquito coils use pyrethroid ingredients that evaporate at around 250°C, spreading into the air with the rising smoke. Interestingly, while the burning tip reaches 800°C (too hot—the active ingredients get destroyed), it’s actually just before that point, in the pre-combustion zone, where the ingredients properly evaporate and start working.
This rising air current carries the insecticide throughout the room, which is why mosquito coils are effective.

What many people don’t realize is that about 90% of mosquitoes don’t fly around constantly—they rest on ceilings and walls. With that in mind, KINCHO created this spray to pre-coat those resting areas with insecticide. So instead of chasing mosquitoes in mid-air, the spray turns your walls and ceiling into mosquito-killing zones.

💡 Highlights

  • Just one spray toward the ceiling = 12 hours of effect
  • Based on real mosquito behaviour: targets where they rest
  • No fire, electricity, or continuous release needed
  • Fast-acting and safe—great for bedrooms, travel, or daily use

Both sprays are a great way to prevent bites before they happen, which is the best kind of protection.

Whether you’re staying home this summer or planning a holiday, mosquito prevention should be on your checklist. Ceiling sprays like these offer a modern, effortless way to enjoy summer nights without the buzzing and biting.

No need for plugs, flames, or complicated setups—just one spray, and you’re done. Try it out and see how easy mosquito-free living can be.
