Bed bug bites

Bed bug bites often appear in a line or cluster on exposed skin — arms, neck, shoulders, legs — and usually show up in the morning. Some people don’t react at all, so a lack of bites doesn’t mean no bed bugs.

How to check for bed bugs

1. Strip the bed and check mattress seams, piping and tags with a torch
2. Check the bed frame joints, screw holes and headboard
3. Check sofa seams and cushions
4. Check skirting, sockets and curtain folds near the bed

Look for black spots (droppings), blood smears, shed skins, eggs and live bugs.

How bed bugs spread in Singapore

Bed bugs hitchhike in luggage, second-hand furniture, shared accommodation and dormitories. The tropical bed bug (Cimex hemipterus) is common here.

What not to do

• Don’t use foggers — they scatter bed bugs into walls
• Don’t sleep in another room — they follow you
• Don’t throw out furniture before inspection

What professional treatment involves

Effective bed bug treatment is 2–3 visits about 10–14 days apart: a detailed inspection, targeted treatment of every harbourage, steam for fabrics, and follow-ups to kill nymphs that hatch from eggs.

What auditors want to see

Auditors assess whether pest control is planned, monitored and acted on — not just whether a contractor visits.

Pest control audit checklist

• Contract and scope of service
• Contractor licence and technician licences
• Insurance certificate
• Pest risk assessment (reviewed annually)
• Numbered device map, current
• Service reports for every visit
• Trend analysis of catches/activity
• Corrective actions with sign-off
• Safety data sheets and approved product list
• Fly light servicing and tube change records

Common non-conformities

• Device map out of date or devices missing
• Toxic bait inside production
• No trend analysis
• Proofing issues reported but never closed
• Fly lights above open product

How often?

Monthly visits are typical for food premises; high-risk sites may need fortnightly service.

Get audit-ready

Our food processing and restaurant programmes include full documentation, and a pre-audit inspection can find gaps before the auditor does.

Why hotels get bed bugs

Bed bugs arrive in guests’ luggage — they are not a sign of poor cleanliness. What matters is how quickly they are detected and contained.

Housekeeping checks

• Check mattress seams, piping and headboards at every bed change
• Look for black spots, shed skins and live bugs
• Check luggage racks and sofa seams

Room response protocol

1. Take the room out of service
2. Bag linens for hot washing
3. Call your pest control provider
4. Inspect adjacent rooms
5. Treat and re-check before release

Proactive programmes

Rotating room inspections and encasements catch problems before guests do. See hotel pest control.

1. Identify which cockroach you have

Singapore homes mostly deal with two species. American cockroaches are large (3–4 cm), reddish-brown and often fly; they live in drains, sewers and bin chutes and enter through floor traps. German cockroaches are small (about 1.5 cm) and light brown with two dark stripes; they live and breed inside kitchens — in hinges, appliances and cabinet corners. The treatment is different for each.

2. Look for cockroach infestation signs

• Droppings like ground pepper or coffee grounds in drawers and corners
• Brown egg cases behind appliances and in hinges
• A musty, oily smell
• Sightings during the day — usually means a large hidden population

3. Cut off food, water and shelter

Wipe counters at night, store food in sealed containers, don’t leave pet food out, fix dripping taps, and take rubbish out daily. Declutter cardboard boxes — German cockroaches love them.

4. Bait, don’t spray

Spray kills the cockroaches you hit but scatters the rest. Gel bait placed in cracks, hinges and behind appliances is eaten and carried back, killing others in the nest. Insect growth regulators (IGR) stop nymphs from becoming breeding adults.

5. Block the drain highway

For American cockroaches, keep floor traps wet (dry traps let them climb up), use floor trap covers, and seal gaps around pipes under sinks.

6. Cockroach prevention routine

• Weekly: pour hot water down floor traps; check under sinks
• Monthly: clean behind the fridge and stove
• Always: check boxes and second-hand appliances before bringing them in

When to call a professional

If you see cockroaches every night, in the day, or in multiple rooms — or you run a food business — professional cockroach control is quicker and cheaper than months of DIY.

Common pests on vessels

• Cockroaches — galleys, mess rooms, provision stores
• Rodents — holds, stores and engine areas
• Bed bugs — crew cabins
• Stored-product insects — provisions and some cargo

Ship sanitation inspections

Vessels need valid Ship Sanitation Certificates under the International Health Regulations. Pest activity found during inspection can lead to required control measures, so treating before inspection is sensible.

How to book attendance

Share vessel name, IMO, location (berth, shipyard or anchorage), ETA/ETD, the pest concern and your agent’s contact. See request vessel attendance.

Prevention on board

• Inspect provisions on loading
• Keep galley equipment voids clean
• Use rat guards on mooring lines
• Report sightings early

Know the Aedes mosquito

Aedes mosquitoes are black with white stripes and bite mainly in the day. They spread dengue, Zika and chikungunya, and breed in clean stagnant water in and around homes.

Weekly breeding prevention

Follow NEA’s Mozzie Wipeout routine:

• Turn pails over and store them under shelter
• Remove water from flower pot plates
• Loosen soil in potted plants
• Clear blockages and put BTI insecticide in roof gutters
• Cover bamboo pole holders when not in use

Hidden breeding spots

• Toilets and floor traps in unused rooms
• Aircon trays and fridge drip trays
• Vases and pet water bowls left for days
• Leaf axils of plants and tree holes

Protect yourself

Use repellent, wear long sleeves at dawn and dusk, and install window screens.

When professional mosquito control helps

Landed homes, condos, construction sites and businesses with gardens benefit from scheduled mosquito control — inspection, larviciding and fogging during high-risk periods.

What drives the price

• Pest — bed bugs and termites need multi-visit programmes
• Property size — a 5-room flat or landed home takes longer
• Severity — established infestations need more work
• Method — baiting, soil treatment, steam and proofing have different costs
• Visits & warranty — follow-ups cost more but work

Typical price ranges

See our live pest control price list for starting prices for cockroaches, ants, bed bugs, termites, rats, mosquitoes and contracts.

How to compare quotes

1. Check the NEA licence
2. Ask what method will be used
3. Count the visits included
4. Check warranty terms
5. Ask for a written report

Red flags in cheap quotes

• One visit for bed bugs
• Spraying only for termites
• No inspection
• “Unlimited” promises with no written terms

For businesses

Contracts are priced monthly. See commercial pest control cost.

Which rodent is it?

Norway rats burrow and live at ground level around drains and bins. Roof rats climb and nest in ceilings and false ceilings. House mice are small and get in through tiny gaps.

Signs of rats

• Droppings along walls and in cabinets
• Gnawed cables, packaging and doors
• Scratching in the ceiling at night
• Grease marks along walls and beams

Find how they’re getting in

Check gaps around pipes, aircon trunking, doors, vents and roof eaves. Rats can squeeze through holes about 2 cm wide; mice through even smaller gaps.

Traps vs baits

Traps are best indoors — no risk of a rat dying in a wall void. Bait should only be used in tamper-resistant stations, away from children, pets and food.

Rat prevention tips

• Bag and bin food waste daily; keep bins lidded
• Store food in hard containers
• Trim trees and vines touching roofs
• Seal gaps with rodent-proof materials

When to call a professional

Any rat in a food premises, or persistent activity at home, needs professional rodent control — including proofing.

7 signs of termites

1. Mud tubes on walls, pipes and skirting
2. Hollow-sounding door frames and cabinets
3. Discarded wings near windows and lights
4. Bubbling paint or warped wallpaper
5. Doors and drawers that suddenly stick
6. Small pellet piles (drywood termites)
7. Soft, damaged flooring

Termite swarms after rain

Winged termites (alates) often swarm around lights in the evening after rain. A swarm indoors suggests a colony nearby — sometimes inside the building.

How to prevent termites

• Fix leaks — moisture attracts termites
• Keep timber, boxes and firewood off the ground
• Avoid mulch and soil against walls
• Ventilate damp storerooms
• Treat soil during renovations, before new carpentry goes in
• Book a yearly termite inspection

Don’t break the mud tubes

Disturbing termites makes them move elsewhere and makes baiting harder. Leave them, take a photo and call a professional.

Treatment options

Baiting eliminates the colony; soil treatment creates a barrier. See termite treatment for a comparison.

10 warehouse pest prevention tips

1. Keep dock doors shut when not loading; fit strip curtains or rapid doors
2. Inspect inbound goods for gnawing, droppings, webbing and insects
3. Leave a 45 cm inspection gap between stock and walls
4. Store off the floor on pallets or racking
5. Clean under racking — spilled product feeds pests
6. Rotate stock (FIFO) so goods don’t sit for months
7. Fix door seals and gaps around pipes and cables
8. Manage waste — lidded bins away from doors
9. Control vegetation along external walls
10. Monitor with numbered rodent stations and pheromone traps

Pests to watch

Rodents (stock and cable damage), stored-product insects (food, tobacco, pet food), termites and wood borers (pallets), and birds (racking).
