It is usually around dusk. A dark shape swoops past the living room light, loops around the ceiling fan and disappears behind the curtains. Finding a bat in house in Singapore is startling, but it is more common than many people think, especially in flats near parks, fruit trees or park connectors. The good news is that a lost bat almost always wants to leave as much as you want it gone.
This guide covers how to let a bat out safely, what not to do, and when to call for help. It focuses on bats only; snakes, monkeys and other wildlife need different handling.
Why Bats End Up Indoors
Singapore has a number of bat species. Some are fruit bats that feed on nectar and fruit, and others are small insect-eating bats that hunt around lights and greenery at night. They play a useful role: fruit bats help pollinate plants and spread seeds, and insect-eating bats eat large numbers of insects.
Bats usually fly into homes by accident. Common reasons include:
- Open windows and doors at dusk, when bats leave their roosts to feed
- Lights attracting insects, which in turn attract insect-eating bats
- Fruit trees or flowering plants nearby, which draw fruit bats close to buildings
- Young bats that are still learning to fly and navigate
A bat indoors is not trying to attack anyone. It is disoriented and looking for a way out.
Step by Step: Helping the Bat Find Its Way Out
Stay calm and keep the situation simple. Most bats leave on their own within minutes if you give them a clear route.
- Move people and pets out of the room. Close the door behind you so the bat stays in one space. Keep cats and dogs well away, as they may chase or bite it.
- Open the windows and any doors to the outside. In an HDB flat, the windows facing the corridor or open air are the obvious exits. Open them as wide as is safe.
- Turn off the lights in that room. Switch on a light outside if you can, or leave the room dark so the open window is the brightest spot.
- Switch off ceiling fans. Spinning blades can injure a flying bat.
- Wait quietly and watch from a doorway. Do not wave towels or brooms around. Chasing a bat makes it panic and fly erratically.
- Give it time. Bats often circle a few times before finding the exit. Once it has left, close the windows.
If the bat has landed and is resting on a curtain or wall and not moving, it may be tired or injured. In that case, see the section on calling for help below.
What Not to Do
Many well-meaning reactions make things worse for the bat and riskier for you. The table below sums up the main points.
| Do | Don’t |
|---|---|
| Keep calm and give the bat a clear, dark route out | Chase, swat or hit the bat with a broom or towel |
| Keep children and pets in another room | Let pets corner, play with or bite the bat |
| Call a wildlife rescue group if the bat is grounded or hurt | Pick it up with bare hands |
| Wear thick gloves if a trained responder advises you to contain it | Spray insecticide, cleaning products or water at it |
| Wash hands well after any contact with surfaces it touched | Try to keep it as a pet or feed it |
The most important rule is do not handle a bat with bare hands. Like many wild animals, bats can carry germs, and a frightened bat may bite or scratch in self-defence. Bats around the world are known to carry viruses and other germs that can affect people, so direct contact is best avoided.
If you are bitten or scratched, wash the wound thoroughly with soap and running water and see a doctor promptly. Tell the doctor that a bat was involved so they can advise you properly. This is general information, not medical advice.
When to Call ACRES or NParks
Some situations need trained help rather than a DIY approach. Call for assistance if:
- The bat is on the floor, cannot fly or appears injured
- It is a baby bat on its own
- It has gone into a gap, false ceiling, cabinet or air-conditioner casing and will not come out
- It has been inside for a long time and shows no sign of leaving
- Someone in the household has been bitten or scratched
- Bats seem to be roosting regularly in or on your building
Two organisations to know:
- ACRES (Animal Concerns Research and Education Society) runs a wildlife rescue service that handles calls about wild animals, including bats. Find the current hotline on the ACRES website and save it in your phone.
- NParks (National Parks Board) manages wildlife matters in Singapore and has an Animal Response Centre for reporting wildlife issues. Check the NParks website for the current contact details and online feedback options.
For bats roosting on common property in an HDB estate, you can also inform your town council, which manages common areas. In a condominium, contact the management office.
While waiting for help, keep the room closed and the bat undisturbed. If a responder asks you to contain it, they will usually advise you to gently cover it with a box while wearing thick gloves, and to slide a piece of card underneath. Only do this if instructed.
Cleaning Up After a Bat Visit
A bat that has spent a few minutes flying around your room usually leaves little trace. If it rested somewhere or left droppings:
- Wear disposable gloves and a mask
- Wipe droppings with damp paper towels rather than sweeping, which can stir up dust
- Clean the area with a household disinfectant
- Throw the gloves and paper towels away in a tied bag
- Wash your hands thoroughly afterwards
If you find large amounts of droppings in a ceiling space or storeroom, that suggests a roost. Contact NParks or a professional wildlife or pest management service for advice rather than clearing it yourself.
How to Keep Bats Out of Your Home
You do not need to seal your flat completely. A few simple habits reduce the chances of another visit:
- Close windows or draw curtains at dusk if bats are often seen nearby, particularly when lights are on.
- Install window mesh or insect screens. These also keep out mosquitoes and other flying insects. Check your town council or condominium rules on fittings if you are unsure.
- Reduce lights near open windows. Fewer insects near your window means fewer reasons for insect-eating bats to come close.
- Do not leave fruit out on balconies or ledges. Ripe fruit can attract fruit bats.
- Check gaps and openings around air-conditioner pipes and vents, and get them sealed by a qualified contractor if needed.
Bats are a normal part of Singapore’s urban wildlife, and most encounters end quickly and harmlessly. If you live near greenery, it is worth checking which way your windows face and how much light they let out at night; our guide on morning versus afternoon sun is a handy primer if you are still choosing a home. For other unwelcome flying visitors, see our tips on dealing with house flies at home and getting rid of drain flies and fruit flies.
