In Singapore’s warm, humid climate, mosquitoes are a year-round nuisance and a real health concern, since some species can spread dengue. Window screens help, but many families also like the extra layer a mosquito net bed cover provides, especially over a baby’s cot. This guide explains the main types of nets, how to get the right fit for adult beds and cots, and the safety points parents should keep in mind for babies and young children.
A net is one part of protection. The most effective step is still removing stagnant water around your home, as outlined in our guide to preventing dengue and mosquito bites. The National Environment Agency (NEA) has up-to-date advice on dengue clusters and prevention.
Why Use a Mosquito Net at Home
A net creates a physical barrier while you sleep, without anything applied to the skin. It is particularly useful when:
- Your home is near greenery, canals or construction sites where mosquitoes are common.
- You prefer to sleep with windows open or use a fan instead of air-conditioning.
- You have a young baby who is too young for some repellents. Check with your doctor or pharmacist about which repellents, if any, suit your child’s age.
- You are travelling within the region and want a portable option.
Types of Mosquito Nets Compared
| Net type | How it works | Best for | Things to watch |
|---|---|---|---|
| Canopy (dome) net | Hangs from a single hook in the ceiling and drapes over the bed | Adult beds, decorative look | Needs a secure ceiling hook; edges must be tucked in |
| Box (rectangular) net | Hung from four corners or a frame | Larger beds, full coverage | Needs four fixing points or a stand |
| Pop-up tent net | Self-supporting frame that springs open | Travel, older children, renters who cannot drill | Check zips and frame stability |
| Cot net | Fitted cover made for a cot or play yard | Babies and toddlers | Must fit snugly with no loose fabric inside |
| Foldable umbrella net | Small cover that opens over a mat or tray | Daytime naps on a mat | Not designed for overnight sleep |
Mesh and material
Look for a fine mesh that keeps out small mosquitoes while still letting air through. Polyester is common, lightweight and quick to dry. Cotton blends feel softer but are heavier and slower to dry in humid weather. Some nets are treated with insecticide. For a baby’s cot, many parents prefer an untreated net. Check the product labelling and ask your doctor if you are unsure.
Getting the Right Fit
A net that is too small leaves gaps; one that is too large leaves loose fabric that can sag or tangle.
For adult beds
- Measure the length, width and height of the bed, including the mattress.
- Choose a net that reaches the floor or can be tucked well under the mattress on all sides.
- For canopy nets, check the drop length from the ceiling hook to the floor.
- If you rent your HDB flat or condo, check with your landlord before drilling into the ceiling. A freestanding frame or pop-up net may be easier.
For cots
- Measure the inside and outside dimensions of the cot, and check the manufacturer’s sizing guide.
- A cot net should fit snugly over the frame, usually with elastic edges or a fitted design, so it cannot fall onto the baby.
- If the cot is a convertible model or a play yard, buy a net designed for that type.
Safety First for Babies and Young Children
Safety is the most important factor when choosing a net for a cot. Keep these points in mind:
- No loose fabric inside the cot. Loose fabric, cords or ties can be a suffocation or strangulation risk. The net should sit on the outside of the cot frame, taut and secure.
- Check fixings regularly. Make sure hooks, frames and elastic remain secure and the net cannot collapse inward.
- Keep cords out of reach. Any hanging cords or ties should be short and well away from where a child can reach.
- Stop using it when your child can climb. Once a toddler can pull up, stand and try to climb, a net over the cot may tempt them to pull on it. Many parents switch to other protection at this stage. Our guide on transitioning from a cot to a bed covers that change in more detail.
- Use only with suitable sleep products. Pair the net with a firm, flat mattress and no pillows, bumpers or soft toys in the cot, following safe sleep advice from your doctor or HealthHub.
- Avoid nets on unsafe cots. If you use a traditional hanging cradle, read our article on whether spring cots (yao lan) are safe for babies before adding a net to one.
If your child shows signs of a mosquito-borne illness, such as high fever, rash, severe headache or pain behind the eyes, see a doctor promptly.
Caring for Your Net
- Inspect for holes. Even small tears let mosquitoes in. Patch them with a mesh repair kit or replace the net.
- Wash gently. Hand wash or use a gentle machine cycle in a laundry bag, then air dry. Treated nets may have specific washing instructions, so follow the label.
- Dry thoroughly. In humid weather, dry fully before storing to prevent mould and odours.
- Close it properly. Lower the net before dusk and tuck it in before sleep, and keep zips closed during the day so mosquitoes do not hide inside.
Other Ways to Cut Mosquitoes at Home
A net works best alongside a few simple household habits:
- Do the regular check for stagnant water around your home, including flower pot plates, pails, roof gutters and the trays under fridges or air-conditioners.
- Keep doors closed at dawn and dusk, when many mosquitoes are most active.
- Use a fan in the bedroom, as moving air makes it harder for mosquitoes to land.
- Fit or repair window screens in bedrooms, especially in ground-floor units or homes near greenery.
Where to Buy
Mosquito nets are sold at department stores, household shops, neighbourhood stores and online marketplaces. Baby stores carry cot nets designed for specific brands; see our guide to baby stores for cots and nursery gear for the kinds of shops that stock them. Before buying, check the dimensions, mesh quality, fixing method and whether the product meets recognised safety standards for children’s products.
Frequently Asked Questions
Is an insecticide-treated mosquito net safe to use over a baby’s cot? Many parents prefer an untreated net for a cot, and labelling varies by product. Check the label and ask your doctor or pharmacist if unsure. The net should sit outside the cot frame, taut, with no loose fabric inside.
When should I stop using a net over my toddler’s cot? Once your child can pull up, stand and try to climb, a net may tempt them to pull on it, so many parents switch to other protection then. This often coincides with moving from cot to bed.
Which type of net works for a rented HDB bedroom where I cannot drill the ceiling? A pop-up tent net or a freestanding frame net needs no drilling, so it suits renters. Canopy nets need a secure ceiling hook, so check with your landlord before drilling.
How do I wash and store a mosquito net in humid weather? Hand wash or use a gentle cycle in a laundry bag, then air dry fully before storing to prevent mould and odours. Treated nets may have specific instructions, so follow the label.
Does a mosquito net replace checking for stagnant water at home? No. A net protects while you sleep, but removing stagnant water around the home is still the most effective step. NEA has current advice on dengue prevention and clusters in your area.
