Part I: Pest Profile - Ants in Singapore

There are more than 10,000 species of ants that can be found in almost every space and the only places lacking indigenous ants are Antarctica and a handful of inhospitable islands. While they are generally not as damaging as termites, they are capable of potentially spreading diseases, contaminating food, and inflicting bites. There is also the carpenter ants that are known to cause damage to wooden structures.

In Singapore, you will commonly come across the following ant species.

Black House Ants

This species of ants are regarded as more of a nuisance than pests. They are intensely black in colour and measure about 2.5-3mm long. These ants prefer sugary liquids and tend to attract aphids that results in extensive plant damage.

Fire Ants

A major agricultural and urban pest that destroys crops and invades residential properties. When aggravated, they can inflict stings that may result in a pustule some 48 hours later and trigger allergic reactions.

Ghost Ants

These ants also called sugar ants, have black heads and pale to translucent legs and abdomen. They feed and nest indoors and are usually attracted to moisture-prone areas including the kitchen and bathroom cabinets.

Odorous House Ants

They get their name from the strong, rotten coconut-like smell they give off when crushed. They feed mostly on sugary food such as sweets and fruits and can be found in areas where there is moisture, including your houseplants.

Pharaoh’s Ants

Light yellow to red in colour, with black markings on their abdomen. They are quite difficult to get rid of because when sprayed, they tend to break up their colony and scatter to new locations, thus further spreading the infestations.

Carpenter Ants

Often mistaken for eating wood, actually burrow into wood to make a nest. Carpenter ants spread fast and often move to accommodate the colony, thus illustrating the necessity to address a carpenter ant infestation immediately.

Crazy Ants

They ave long legs and are usually black or dark red in colour. They derive their name from their defence mechanism: when disturbed, they will scatter in all directions, making them difficult to kill.

How to Identify Ants in Singapore

Very often, ants are mistaken for termites and vice versa. Understanding the difference between these two is essential to ensure the effectiveness of pest removal.

It is actually easy to recognise ants with their elbowed antennae, narrow waists, and bulbous abdomens. They have three distinct body segments—head, thorax, and abdomen—while termites do not have. They are also different in colour, where most of them are black, brown, or reddish-brown in colour.

Is that a Flying Ant or Termite?

Some ants are winged and they are called swarmers whose primary objective is to find a mate and start new colonies. Similarly, they are also often mistaken as flying termites but one way to tell between them is by looking at their wings.

While ant swarmers have two sets of wings, with the front pair larger than that of the rear, termite swarmers have four wings that are all identical in shape and size. Ants mate in the air and after which the male will die soon after.

Inside the Ant Colonies: Ant Life Cycle & Caste System

Ants go through four different life stages from eggs to larvae, pupae, and adults. The larvae are white, translucent, and resemble maggots. They will undergo different moulting stages until they metamorphose into pupae. In some ant species, the pupae spin cocoons around their bodies until they develop into adults, while others get by without them. The process takes about 6 weeks to 2 months to complete and ants can live for about 90 days or for as long as 6 months to a year.

interesting facts about ants

In an ant colony, there is the queen, female workers, and males. The queen is responsible for laying eggs while the male ants’ role is to mate with future queen ants—they do not live very long afterwards. Meanwhile, the workers do all the labour, which involves tending to the offspring and rescuing the pupae in case the nest is disturbed. They are also responsible for gathering food, constructing the nest, and keeping the colony clean.

Depending on the species, an ant colony can consist of millions of ants and may have one or more queens. It can also have soldiers that protect the queen, defend the colony, and attack enemy colonies in search of food and nesting places.

Ants live underground and sometimes in dead wood and plant cavities. In Singapore, they are often found in homes, particularly where their food sources are: bathroom and kitchen. They can also be found nesting in the cracks and crevices of your wall or outside your home where they can build anthills.

why do you see more ants in your home lately

Part II: Why Do You See More Ants in Your Home Lately?

Everyone gets the occasional ants at home in Singapore, as they easily sneak in through open doors and windows in search of food, water, and shelter. However, a sudden ant invasion does not just happen randomly—there are usually triggers that cause it, some of them are as follows.


Crumbs, spills, uncovered food, pet food, and even the food waste in the bin are all typical causes of ant invasions. When ants discover these food sources, they travel back to their nest, send a signal to other workers, and suddenly, a swarm of ants are marching back into your home to pick up the food.

Nearby Nest & Entryways

Another potential cause of sudden ant invasions is the presence of ant colonies near your home, coupled with the many cracks, holes, and openings that serve as an entryway into your property. It pays to engage a local pest control service to inspect your property for colonies, address them, and seal all the possible entries that ants are entering.


Ants, like many pests, thrive in the warm and humid weather in Singapore. They are most likely to enter homes in wet conditions in search for dry grounds and likewise, they may also seek protection from the heat in your homes, where they have easy access to water. They may even build nests near your home, where they are closer to resources.

Your Neighbours Have an Ant Infestation

Sometimes, it is not you, but the people around you. No matter how well you may be keeping your home, if you have neighbours who have an infestation, they may start invading your home as well. This is particularly true if you live in an apartment where you share walls with your neighbours.

Other Causes of Ant Invasions

There are many other reasons why you may be suffering from an ant invasion. For instance, carpenter ants may have discovered wood in your premises or they may have already created a nest within your property and are living indoors. Whatever is the case for you, the most effective way to get rid of ants is by eradicating the colony and reducing, if not fully removing, all their potential entry points.

Signs of Ant Infestations

While there may be a few ants in your kitchen, do not be fooled. Underneath your sinks or behind your furniture, there could be more ants lurking. Below are some of the signs of an ant infestation to keep an eye out on.

Live Ants: The most obvious way to see if you have ants is to look at any food that you have left out. If ants are present, so does a likely infestation.

Ant Trails: Ants produce pheromones that they use to create chemical trails from their nests to their food sources. Trails like these in and out of your home could indicate an infestation.

Ant Nests: A nest site can look like anything from a small pile of dirt to the classic anthill. However, carpenter ant nests can look like a small hole on wood in areas like your windows panes, furniture, door frames and cabinets.

where to look for signs of ants infestations

Ants can be found anywhere there is food, moisture, shelter—the primary things they need to survive. When searching for ants, it pays to know what attracts them into your home in the first place.


Any food that appeals to you probably appeals to ants too, but what ants are particularly fond of are sweet foods. Any exposed food or spilt liquids can be a tempting source of food for ants.


Any leaks, drips, and moisture build-up in and around your home are enough to attract ants into your home. It explains why besides the kitchen, ants are found in your bathroom too.


The sweltering heat and the wet conditions during the occasional rains are two ways to drive ants into your home. Do not be surprised when you find that ants have moved their nests into your cosy home.

Entry Points

Ants are opportunistic and they will take any possible way to get into your home. If you have ants, you probably have an existing entry point somewhere. There is not much you can do to keep ants away, as they do not require much space to get inside. However, there are ways to keep your home as uninviting as possible to ants.
