Mosquitoes in Singapore

Mosquitoes are annoying, their bites are itchy and they can transmit serious diseases. The need to control mosquitoes inside and outside the home is important so you can enjoy life and keep healthy. Controlling mosquitoes requires combining mosquito prevention tips with suitable mosquito control products.



Eggs: Eggs are laid in water singly or in “rafts” containing multiple eggs. The exact location will vary by species, but typically they are laid in stagnant or slow moving water.

Larvae: The larvae or “wrigglers” can often be seen in pools of water. They rest upside down with the “tail-end” of their body pointing through the water surface to breathe. They dive or wriggle away from the surface when disturbed.

Adults: Everyone could probably identify a mosquito, they are insects, part of the fly family. Their size depends on the species but they rarely exceed 1.5cm in length. Their mouthparts have been adopted to allow them to pierce skin and suck up blood.


Signs of mosquito infestation are fairly obvious – lots of mosquitoes and lots of bites! However, if you want to get an early indication a problem may be brewing, keep an eye on any pools or water around your property. If you can see lots of “wrigglers” you know will be about get an invasion of adult mosquitoes.


Adult mosquitoes eat nectar and other plant juices. Only the female mosquito bites, requiring a blood meal before laying eggs.

Mosquitoes are not only a problem at dusk and during the night. Some species are day biters such as the Asian Tiger mosquito (Aedes aegypti) which carries Dengue Fever.

The high pitched sound you can hear when mosquitoes are near your head, is from the rapid beating of their wings.


The key action to minimise mosquito numbers on your property is to remove potential mosquito breeding sites. Eliminating all sources of standing water will remove egg laying sites. These include ponds, plant pots, drains and blocked gutters.

Stopping mosquitoes coming inside is best achieved using mosquito screens
When outside wearing loose, long-sleeved tops and long trousers with socks will significantly reduce the chance of mosquito bites.


To control the occasion mosquito inside the house, use a flying insect aerosol to spray towards the insect. Spraying the aerosol into the air will create a cloud of insecticide which the mosquito will fly through.

If you experience a large number of mosquitoes indoors (especially if you do not have insect screens), spray insecticide onto surfaces where mosquitoes rest during the day. Typical resting places are dark, sheltered places such as behind cupboards and drawers, under furniture and behind pictures.

Reducing adult numbers outdoors can be achieved by spraying surfaces where mosquitoes may rest, these include under eaves, decking roofs, decking flooring, under plant leaves and general sprays on the exterior walls of homes near entertaining areas.
