Insect Repellent Singapore: A Practical Guide for Cockroaches, Ants & Charlie Ants

Insect Repellent in Singapore: Dealing With Common Household Insects

Singapore's warm and humid environment means unwanted insects can sometimes find their way into

our homes.

You may notice cockroaches appearing around the kitchen at night, ants travelling along the edges of

walls, or small insects entering through windows and balconies.

Another insect Singapore residents may encounter is commonly called the “Charlie ant.” Despite its

name, a Charlie ant is not actually an ant. The term is commonly associated with Paederus rove beetles.

While every insect behaves differently, one useful starting point is identifying where insects are

entering, hiding and travelling around your home.

For crawling insects, floor edges, wall corners, gaps, kitchens, bathrooms and entrances are particularly

useful places to monitor.

Why Do Insects Keep Appearing Around the Home?

An insect appearing in your home doesn't necessarily mean your house is dirty.

Insects enter buildings for many reasons.

1Food Sources

Crumbs, food residue, unsealed food and rubbish can provide an attractive food source for ants and

cockroaches.

Pay particular attention to areas underneath kitchen appliances and cabinets where food particles can

easily be overlooked.

Water and Moisture

Kitchens, bathrooms, sinks and other damp locations can provide moisture.

Cockroaches in particular need access to food, water and shelter.

Small Hiding Places

Cracks, gaps, cabinets, cardboard boxes and clutter can provide places for insects to hide.

Cockroaches often prefer dark and sheltered locations.

Entry Points

Small insects don't need a large entrance.

Check areas around:

• Doors

• Windows

• Floor edges

• Wall gaps

• Pipes

• Drains

• Balconies

• Kitchen cabinets

Finding recurring insect pathways can help you understand where the problem may be coming from.

Cockroaches: Why Do They Keep Appearing?

Cockroaches are one of the most unpleasant household pests for many Singapore residents.

They often prefer warm, dark and sheltered areas and may become more noticeable at night.

Where Should You Check for Cockroaches?

Pay particular attention to:

• Under the kitchen sink

• Behind refrigerators

• Behind cabinets

• Around rubbish bins

• Floor corners

• Wall gaps

• Bathrooms

• Drains

• Dark storage areas

If you continuously see cockroaches, simply dealing with the insects you can see may not address the

underlying problem.

Look for possible food sources, moisture, hiding locations and entry points.

Reduce Food Sources

Clean crumbs and spills promptly.

Keep food in properly sealed containers and don't leave rubbish sitting around longer than necessary.

Regularly clean underneath appliances and other difficult-to-reach areas.

Reduce Hiding Places

Unnecessary cardboard boxes, newspapers and clutter can provide additional places for cockroaches to

hide.

Keeping these areas organised makes it easier to monitor insect activity.

Seal Cracks and Gaps

Inspect walls, cabinets and other areas for cracks or openings.

NEA guidance on cockroach prevention also emphasises cleanliness, proper refuse management and

sealing cracks, crevices and openings where pests can hide.

Ants: Follow the Trail

Ants behave differently from cockroaches.

If you notice several ants moving along the same route, they're often following an established trail.

Instead of immediately focusing only on individual ants, look at where they're travelling.

Common Ant Pathways

You may find trails around:

• Floor edges

• Wall corners

• Kitchen counters

• Windows

• Door frames

• Cabinets

• Food-storage areas

Follow the trail if possible.

You might discover that the ants are being attracted by something as simple as a few crumbs, spilled

drinks or an improperly sealed food container.

Keep Food Areas Clean

Sweet drinks, sugar, food residue and crumbs can attract ants.

Wipe kitchen surfaces regularly and clean spills as soon as possible.

Store food properly and keep rubbish covered.

What Is a Charlie Ant?

Here's where things become interesting.

Despite its popular name, a Charlie ant isn't actually an ant.

“Charlie ant” is a name commonly used for certain Paederus rove beetles.

That means treating them exactly like ordinary household ants isn't necessarily appropriate.

Don't Crush Charlie Ants Against Your Skin

If you encounter what you suspect is a Paederus rove beetle, avoid crushing or rubbing it directly

against your skin.

Instead, remove the insect without crushing it against yourself.

If you frequently encounter these insects, look at where they may be entering your home.

Check Windows and Entrances

Pay attention to:

• Windows

• Balcony doors

• Entrance doors

• Areas around lights

• Gaps around window frames

Reducing opportunities for insects to enter can be an important part of household insect management.

Why Floor and Wall Corners Matter

Look closely at how crawling insects move around a room.

They don't always travel directly across the centre of an open floor.

You may notice activity along:

Floor edges

Wall corners

Behind furniture

Under cabinets

Around entrances

Near pipes

Around kitchen areas

These areas are therefore worth inspecting regularly.

If your particular insect-repellent product is designed for surface application, follow its directions

carefully regarding exactly where and how it should be applied.

Using a Lemongrass-Based Insect Repellent

Lemongrass is widely associated with plant-based insect-repellent formulations.

Our insect repellent uses a lemongrass-based formula and is intended to be used according to the

directions supplied with the product.

For products designed for surface application, areas such as floor edges or wall corners may be relevant

application points only when permitted by the product's directions.

Always follow the label regarding:

• Where to spray

• How much to apply

• How frequently to apply

• Surfaces to avoid

• Storage

• Precautions

Using more product than recommended does not necessarily provide better results.

Don't Depend on Repellent Alone

A good household insect-management routine should address the reason insects are appearing in the

first place.

Think of it as several layers.

Step 1 — Keep the Home Clean

Clean food spills and crumbs regularly, particularly around kitchens and dining areas.

Step 2 — Remove Food Sources

Keep food properly stored and rubbish covered.

Step 3 — Reduce Moisture

Look for unnecessarily wet or damp areas around kitchens and bathrooms.

Step 4 — Remove Hiding Places

Reduce clutter and regularly clean difficult-to-reach areas.

Step 5 — Block Entry Points

Inspect doors, windows, pipes, cabinets, cracks and gaps.

Step 6 — Use Appropriate Insect-Control Products

Where appropriate, use your chosen insect-control or repellent product according to its label.

Singapore's approach to pest management increasingly emphasises Integrated Pest Management:

preventing the root causes of pest problems and combining appropriate methods instead of depending

entirely on pesticide application.

Frequently Asked Questions

What is a good insect repellent for Singapore homes?

There isn't one solution suitable for every insect problem. Consider which insect you're dealing with,

where the activity occurs, how the product is intended to be used and its application instructions.

Where do cockroaches normally hide?

Cockroaches commonly seek sheltered areas with access to food, water and hiding places. Kitchens,

gaps, cabinets, areas behind appliances and other dark locations are worth checking.

6Why do ants keep appearing in my kitchen?

Ants may be attracted to food, sweet liquids, crumbs or other accessible food sources. Following their

trail may help identify what is attracting them or where they're entering.

Is a Charlie ant really an ant?

No. The name “Charlie ant” is commonly used for certain rove beetles. They are beetles, not true ants.

Can I spray insect repellent on floor and wall corners?

Only if the specific product is intended and labelled for that type of surface application. Always follow its

usage directions.

What should I do if insects keep coming back?

Look beyond the insects themselves. Check food sources, moisture, rubbish management, hiding places

and potential entry points. Persistent or significant infestations may require professional pest

management assistance.

A Practical Approach for Singapore Homes

Finding cockroaches, ants or Charlie ants inside your home can be frustrating, but randomly spraying

every surface isn't necessarily the best solution.

Start by understanding where the insects are coming from.

Check your floor edges, wall corners, kitchen, bathroom, windows, entrances and other recurring

insect pathways.

Keep food properly stored, remove crumbs and rubbish, reduce hiding places and seal potential entry

points where possible.

Then, where appropriate, incorporate a properly used insect-repellent product into your household

routine.
