What is Larviciding?


Have you been spending your time doing some outdoor activities, only to cut it short due to mosquitoes? While it’s normal to experience some mosquito bites when you’re out doing some activities, it can be fatal if you’re not aware of the kind of mosquito around you, especially Aedes mosquitoes. As the humid and wet weather persist in Singapore, you should take extra precautions to prevent yourself from contracting dengue infection.

Additionally, with the impending rise of dengue cases in Singapore this year, local news outlet have reported it surpassing the total number of dengue cases for the year 2019. The National Environment Agency (NEA) has also reported that the number of cases per week have breached the 1,000 mark. If these data isn’t alarming enough for you to take immediate action, the following are some basic knowledge about mosquitoes and tips to control mosquito populations.

Understanding mosquitoes 

Capable of transmitting life-threatening diseases such as dengue, malaria, yellow fever, and Zika fever, female mosquitoes feed on human blood to obtain the protein to aid in the development of their eggs. While feeding on your blood using their elongated, piercing mouth parts, they can transmit the disease to you.


The most common reaction to a mosquito bite is the itchiness that follows, and then a mild swelling. If you’ve been bitten by an Aedes mosquito, you might be at risk of contracting dengue. Caused by any one of the four viruses known as stereotypes, the symptoms of a dengue infection varies from mild to those requiring medical intervention. In some cases, it may be fatal.

Dangers of Dengue

The World Health Organization (WHO) has classified dengue into two categories – dengue (with/without signs) and severe dengue. Ahead, we are sharing the varying symptoms of dengue.

  • Dengue (with/without signs)

    • High fever (40°C)

    • Severe headache

    • Pain behind the eyes

    • Muscle and joint pain

    • Nausea

    • Vomiting

    • Swollen glands

    • Rash

  • Severe dengue

    • Severe abdominal pain

    • Persistent vomiting

    • Rapid breathing

    • Bleeding gums

    • Fatigue

    • Restlessness

    • Blood in vomit

Should anyone be infected with dengue and suffer from severe symptoms, it can be a life-threatening situation. Thus, it’s crucial to recognise the symptoms early and seek proper medical treatment.

Other than recognising the symptoms, it’s also important to identify the possible breeding grounds of Aedes mosquitoes, be it outdoors or inside your house.

Signs of mosquito invasion 

As mosquitoes are small and often undetectable at times, you can identify them easily when you hear the annoyingly high-pitched buzzing sound. Be it indoors or outdoors, mosquitoes can fly anywhere they want with their tiny-winged body. So it’s important to check for areas that could potentially be their breeding ground. Mosquitoes are attracted to standing water such as water trays for houseplants or water bowls, where female mosquitoes lay their eggs. You might also spot them buzzing around in dark areas. If you happen to be dressed in dark-coloured outfit, you could be their next victim. It’s also important to check for any stagnant water inside or outside your house as it can be an ideal breeding spot for mosquito larvae.

Ways to control mosquito invasion 

Mosquitoes can be a pain in the arse at times. But, you can control their population by keeping your surroundings clean or eliminate them entirely with the help of a professional home disinfection service. Ahead, we’re sharing ways to control mosquito invasion, ensuring that you’ll have mosquito-free days ahead.

  • Installing mosquito net on windows and doors – If you’ve had enough of mosquitoes invading your home, you can opt to install mosquito netting or screen to minimize their invasion, whilst protecting yourself and your family from potential infection.

  • Use mosquito repellent or patch – Before stepping out of the house to do some outdoor activities, be sure to spray mosquito insecticide around the house and use mosquito repellent on yourself.

  • Remove or clean potential breeding grounds – Mosquitoes are attracted to standing water so be sure to remove or clean any item that’s constantly filled with water.

  • Hire professional disinfection service – If you believe that your house or the surrounding areas have been invaded by mosquitoes, it’s best to seek disinfection services to handle the situation as they can provide an integrated solution.

Chemical control – Larviciding 

In Singapore, it’s common to hear about mosquitoes being a pest to almost every home and neighbourhood. With the rising number of dengue infections on the island, it’s important to be vigilant and take the necessary measures to protect your health as well as others. One of the ways to control the mosquito population is to target their habitats using chemical control, i.e. larviciding.

For the eggs to be an adult mosquito, it requires about 7-10 days. To prevent such development, larvicides are applied to water sources that are home to mosquito eggs and larvae. Thus, reducing the population of immature mosquitoes and eliminating the mosquito population over time.

Larvicides come in various forms such as liquids, tablets, pellets, granules and briquettes. When used according to the product’s instructions, it’s harmless to people, pets and the environment except mosquito larvae. If you prefer to let the professionals handle the situation at hand, why not let PestBusters do the job?

Pest control Solutions 

PestBusters offers an Integrated Pest Management programme, designed to strike out and fully eliminate pest infestations. We will inspect the affected area to identify the species of pest, exploit their weaknesses, and establish food sources. Then subsequently formulate a strategy to disorientate the pests.

Among the strategies offered by PestBusters are fumigation, commercial and residential, termite management, and mosquito control. If you’re looking for a mosquito control service, you’ve come to the right place.


The following are the three methods we use to control mosquito population:

  • Larviciding – An efficient way to provide an environment safe from mosquitoes by spraying the chemical at the right places.

  • BTI (Bacillus Thuringiensis Israelensis) – A biological agent specially formulated to target only mosquito larvae, allowing for a total destruction within 24 hours.

  • Misting – A fogging alternative that is safe and eco-friendly. The droplets of chemicals coat the surrounding vegetation without harming the flora and fauna. Once the mosquitoes feed on the plant sap, they die instantly from ingesting the chemical.
