Bed bugs have made a significant comeback across Australia in recent years. They’re not a sign of an unclean home, they’re expert hitchhikers that travel in luggage, second-hand furniture, and clothing. What matters once you have them is knowing what actually works to eliminate them.

Our bed bug control service covers Melbourne homes, apartments, and short-stay rental properties with professional-grade heat and chemical treatment options. In this guide we break down the signs to look for, every treatment method available, realistic costs, and why getting it right the first time saves money.

What Are Bed Bugs and Where Do They Come From?

Bed bugs (Cimex lectularius) are small, flat, reddish-brown insects about the size of an apple seed. They feed on human blood at night and hide in mattress seams, bed frames, behind headboards, in wall crevices, and inside electrical outlets. Common entry points:

• Returning from travel (hotels are a common source)
• Purchasing second-hand mattresses, furniture, or clothing
• Guests staying who have bed bugs in their own home
• Shared laundry facilities in apartments

Melbourne’s busy short-stay accommodation sector has contributed to increasing bed bug cases. Once in a building they can spread between adjoining units through wall cavities and shared walls.

Signs You Have Bed Bugs

Bites are often the first indicator, small itchy red welts in clusters or lines on exposed skin. However, reactions vary enormously; some people show no reaction at all, letting infestations go undetected. Physical signs to look for:

• Small dark spots (excrement) on mattress seams, sheets, and bed frame joints
• Blood spots on pillowcases or sheets
• Shed skins, bed bugs moult as they grow through life stages
• A sweet, musty odour in rooms with heavy infestations
• Live or dead bed bugs in mattress seams, box springs, bed frames, and nearby furniture

If you suspect bed bugs, do a careful inspection with a torch before calling us. Then visit our bed bug service page to understand your treatment options.

Bed Bug Treatment Options: What Works and What Doesn’t

Bed bugs are notoriously difficult to eliminate, and the wrong treatment approach doesn’t just fail, it gives the population time to spread.

• Heat treatment – widely regarded as the most effective single treatment. Raising the internal temperature to around 50°C kills bed bugs at all life stages, including eggs. Heat penetrates cracks, seams, and voids where chemical treatments can’t always reach. More expensive, but often resolves the problem in one visit.
• Chemical treatment – professional-grade insecticides with long-lasting residual activity, using multiple products with different modes of action to address resistance. Usually requires two or more visits spaced 2–3 weeks apart to catch newly hatched eggs.
• Combination approach – heat plus chemical offers the highest likelihood of complete elimination in a single treatment cycle. Recommended for severe infestations.

What doesn’t work: over-the-counter surface sprays, mattress encasements alone, ultrasonic devices, and DIY fumigation. These may temporarily reduce visible activity but will not eliminate the infestation. Our bed bug service page explains our full approach in detail.

How Much Does Bed Bug Treatment Cost in Melbourne?

Chemical treatment for a single bedroom typically starts from around $300–$500. Heat treatment is more expensive, generally $1,000–$2,500+ for a full property, though this varies significantly by size.

Important perspective: a failed DIY attempt followed by delayed professional treatment means the infestation has more time to spread, increasing cost and complexity. Getting thorough professional treatment done the first time is almost always the most cost-effective approach.

Preparation Before Bed Bug Treatment

Treatment effectiveness depends significantly on preparation. Key steps,  your technician will provide specific instructions:

• Wash and tumble-dry all bedding, clothing, and soft furnishings on the highest heat settings. Place in sealed bags immediately after drying.
• Vacuum mattresses, bed frames, and floors thoroughly, then seal and dispose of the vacuum bag outside.
• Clear clutter from around beds and bedroom furniture to allow full access.
• Remove items from drawers and wardrobes.
• Remove pet food and water bowls; cover or remove fish tanks.

You can download our full preparation checklist from our preparation page before your visit.

What to Expect After Treatment

It’s normal to see some bed bug activity in the first days after treatment, adult bugs protected in pupal cocoons will emerge and encounter the residual insecticide. Two to four weeks after treatment, you might see a second wave as another batch of pupae emerges. This is completely normal, it’s the flea and bed bug life cycle playing out, not treatment failure.

Do not vacuum treated carpets for at least two weeks. Continue treating your pets with vet-recommended flea products. If you’re still seeing significant live activity six weeks after treatment, contact us for a reassessment.

Bed Bugs in Short-Term Rentals and Apartments

A single bed bug complaint on your Airbnb or rental property can affect booking rates for months. We provide discreet professional treatment for short-stay rental properties with flexible scheduling to minimise downtime.

For body corporate and apartment managers, we offer building-wide assessments where spread between units is a concern. Visit our commercial pest control page for more on our multi-tenancy programs.

Frequently Asked Questions

Can I sleep in my room during treatment?

During chemical treatment, stay out for the period specified by your technician, typically a few hours. For heat treatment, vacate the property during treatment.

How did I get bed bugs if I haven’t travelled recently?

Bed bugs can come in on second-hand furniture, via guests, through shared walls in apartments, or on returned items. Travel isn’t the only vector.

Do I need to throw away my mattress?

Not necessarily. Mattress encasements and professional treatment can often save a mattress. Your technician will advise based on condition and infestation extent.
