An empty home with standing water, uncovered food waste and reduced air circulation can attract mosquitoes, cockroaches and mould. A short checklist before, during and after your trip can help reduce common problems.
Before you leave
Standing water
The NEA advises removing stagnant water to prevent Aedes mosquito breeding. Before travel:
- Empty, scrub and turn over plant saucers, flower vases and any water-holding containers.
- Cover or store open water containers.
- Check accessible household drains for visible obstructions without dismantling them. Report roof gutters, unsafe access or common-property problems to the responsible maintenance party.
- Follow NEA guidance for outbound travellers, including covering toilet bowls and floor traps. Do not alter existing drain fittings or water seals.
Food and waste
- Clear all food waste and take out rubbish before leaving. An uncovered bin in an empty kitchen attracts cockroaches and ants.
- Store open dry goods in sealed containers.
- Clean kitchen surfaces, stovetop and sink drains. Organic residue in a drain supports drain fly breeding.
- Empty and clean the fridge drip tray if accessible.
Existing pest activity
- If you already have an active pest issue, address it before leaving rather than after. An unattended infestation can worsen while the home is empty.
- Record what you see (photos, locations) so an assessor can compare before and after.
While you are away
- If possible, ask a trusted person to check the home periodically: check the toilet and floor-trap covers, look for pooling from rain or appliance leaks, and remove any delivered mail or packages from outside the door.
- A fully closed home with no air movement and high humidity can encourage mould growth. Consider what ventilation options are practical and safe for your property while you are away.
When you return
- Check for standing water: saucers, trays, containers, balcony items.
- Look for pest signs: droppings, egg cases, dead insects, musty smell, new mould patches.
- Check toilets and accessible drains before returning them to normal use. Ventilate where safe and practical; do not run a ventilation or air-conditioning system suspected of mould contamination.
- Unpack suitcases using the luggage checklist to avoid introducing bed bugs from travel.

Leaving Your Singapore Home Empty for a Holiday FAQs
How quickly can mosquitoes breed in standing water?
Aedes mosquitoes can complete their life cycle in as little as a week in warm conditions. Even a short holiday can allow breeding if water is left standing.
How can I manage humidity while away?
Options depend on your property and the duration. Consider what practical and safe ventilation or dehumidification arrangements are available. Consult your equipment manufacturer guidance for any system left running unattended.
Can pests enter while no one is home?
Yes. Cockroaches, ants and rodents can enter through gaps, drains and pipe entries. Sealing food and clearing waste reduces accessible food sources, but it does not prevent all entry.
What if I return to mould on walls or in wardrobes?
A closed, humid home without air circulation is prone to mould growth. Photograph the affected areas and arrange a professional assessment if the mould covers more than a small patch.
