Bed bug treatment in Sydney

Itchy mornings, and dark spots on the sheets.

Bed bugs in a Sydney home or unit usually show up as bites and small dark spots on the mattress, and treating them properly takes a pest business more than one visit.

Is it bed bugs?

Check the mattress seams with a torch. healthdirect lists spots of blood on the sheets, brown spotting from droppings, shed skins, cream coloured eggs about 1 mm long and live bugs, and big infestations can give off a sickly sweet smell. Adults are flat, oval and up to 6 mm, light brown before a feed and rust red after.

Bites tend to land on exposed skin such as the arms and shoulders. Some people don't react for up to 9 days, and as many as 1 in 5 don't react at all, so one person in the bed can be bitten while the other notices nothing. On black or brown skin the spots can look purple and be harder to see.

Bed bugs and Sydney living

Where people come and go

Better Health Channel says bed bugs are most often found where occupants change often, such as hotels, hostels and apartment complexes, but any household can get them. They travel in luggage, clothing, bedding and furniture.

What NSW Health says

NSW Health says bed bugs aren't known to spread disease and aren't considered a public health hazard, but the itching, lost sleep and scratched skin are real enough.

Unit blocks and notice

Treating the common areas of a NSW residential complex normally needs a pesticide use notice to residents at least 5 working days ahead. There's an exception for emergency work on biting or dangerous pests, if a notice is displayed and records are kept, so ask your strata manager which applies.

Renting

NSW landlords are generally responsible for pests present when a tenancy starts, and tenants for pests their own activities bring in. If you can't agree, NSW Fair Trading's dispute service can help.

Before the technician comes

  1. Leave the bed where it is

    The technician needs to see where they're living, so keep the mattress and bed frame in place until after the inspection.

  2. Don't spray the bedding

    Better Health Channel advises against treating bedding with pesticide.

  3. Write down the pattern

    Note who's been bitten, where on the body, and which bed or couch they'd slept on.

  4. Check what came in recently

    healthdirect suggests checking second-hand furniture before it comes inside, and checking luggage and hotel beds when you travel.

Questions for the pest business

  • Will the treatment combine non-chemical and chemical methods? Victoria's Department of Health says a mix is typically needed.
  • How many visits do you expect, and how far apart?
  • What should we do with clothes, bedding and soft toys before each visit?
  • Which product will you use, and what's its full name?
  • In a unit, should the units either side be checked too?

If it were us

We'd strip the bed, check the seams and bed frame with a torch, and photograph whatever turned up. Then tap Bed bugs, and if you rent or live in a unit, tell the agent or strata manager in writing.

Questions

Bed bug treatment in Sydney: common questions

Why does it take more than one visit?

Better Health Channel says repeat visits may be needed because bed bugs pass through several life stages, and eggs hidden in seams can hatch after the first treatment.

What should I do about the bites?

healthdirect says wash them with antiseptic soap, use an ice pack for swelling and an anti-itch cream, and try not to scratch. They usually clear up on their own; see a doctor if one looks infected, and call 000 for any sign of a severe allergic reaction.

Does having bed bugs mean the place is dirty?

No. Bed bugs feed on blood, not crumbs, and any household can pick them up from luggage or furniture.
