Bed bug guide
How to Get Rid of Bed Bugs
The honest version: what to do tonight, what to stop buying, what a staged treatment looks like from your side of it, and what a real result looks like three weeks later.
Flat, reddish brown, about the size of an apple seed. This is what you are looking for.
Almost nobody looks up how to get rid of bed bugs calmly. It usually happens at two in the morning, after a third night of waking with fresh marks on an arm, and the first instinct is to buy something and spray the bed with it. That instinct costs people more weeks and more money than any other decision in this pest.
What follows is the version Tim talks people through on the phone, written out in order. Being certain you have them before you spend anything. The handful of jobs you can do yourself that genuinely move the needle. The products that quietly make the problem bigger. What a staged treatment looks like from the householder's side. And what a realistic outcome looks like three weeks later, which is rarely what the packaging promises. You will find it alongside Tim's other pest control guides.
Two things are worth knowing before you read on. These insects live indoors and do not care what month it is, so a heated house in Reservoir or Richmond runs them at full speed in July. And a home with them says nothing about the people living in it. They arrive in a suitcase, in a bed base off a hard rubbish pile or through a shared wall, and a spotless bedroom is as open to them as any other.
Step one
Are you certain it is bed bugs?
Buy nothing until you have found a live insect, a shed skin, an egg or the dark spotting they leave along a seam. Marks on skin are not proof of anything. Fleas, carpet beetle larvae, mites, scabies, a reaction to a new washing powder and plain stress hives all leave marks that people read as bed bugs, and every one of those needs a different answer.
Three finds settle it. A live insect, flat and oval and the colour of a dried apple seed. Pale empty husks, which are the skins a juvenile sheds on its way to adult. And the spotting: full stops of digested blood dotted along piping, in joints and inside screw holes. Eggs confirm it too, though they are hard work to spot, barely a millimetre, pearl white and cemented in place rather than loose.
- Nymph
- A juvenile bed bug. It needs a blood meal before each of its five moults, which is why a settled population leaves a scatter of discarded skins around its hiding places and why juveniles usually outnumber adults.
Plenty of things get blamed on bed bugs and turn out to be something else.
- Fleas bite low, around ankles and shins, jump when disturbed, and usually arrive with a cat or dog in the house.
- Carpet beetle larvae shed tiny bristly hairs that irritate skin, and the larvae themselves look like small fuzzy grains along skirtings and under rugs.
- Mosquito marks are scattered and random rather than grouped near where a sleeve or a strap ended.
- Skin conditions and reactions to detergent, sunscreen or a new mattress topper are common, and a pharmacist can usually sort that out in five minutes.
Where Melbourne homes pick them up follows a pattern. Travel is the main one, and the city's visitor peak over January and February, plus the school holiday rush through hostels, serviced apartments and share accommodation, is when the calls cluster. Second-hand furniture is the next most common route, especially a bed base, a bedhead or a lounge taken off a nature strip. In flats and townhouses they also simply walk, along service penetrations and under doors, which is why one unit treated on its own can stay under pressure from next door.
If you have not physically searched the bed yet, do that before anything else. The torch and card inspection routine takes about twenty minutes and tells you more than any amount of reading. If you have already found something and want to know what it means, the rundown of bed bug signs ranked by reliability is the quicker read.
Tonight
What can you usefully do before anyone arrives?
Five jobs help, and none of them cost anything: strip and hot wash the bedding, bag what cannot be washed, vacuum the bed and the floor edges, clear the clutter from around the bed, and move no furniture at all while you keep sleeping where you always sleep. Almost everything else people try in the first week either achieves nothing or spreads the population into a second room.
- Hot wash, hot drySheets, covers, pillowcases and pyjamas on the hottest setting the fabric allows, then at least half an hour in a hot dryer.
- Bag the restAnything unwashable goes into sealed plastic and stays sealed until the rooms have been treated and checked.
- Vacuum and binCrevice tool along piping, joints, slat holes and carpet edges, then the bag straight into a sealed bag in the outside bin.
- Clear the floorBoxes, shoes and storage out from under the bed so edges can be reached, without carrying any of it to another room.
The dryer matters more than the wash. Heat is what kills every stage, including eggs, and a cycle on hot does that where a cold-water wash and a line in the shade will not. Victoria's health department guidance puts the laundry threshold at sixty degrees Celsius and above, with at least thirty minutes on the dryer's hot setting, so check what your machine actually runs at rather than assuming.
Handling the laundry is where people undo their own work. Stripped bedding travels to the machine sealed in a bag, never bundled against your chest, or you drop insects the length of the hallway. Clean dry washing goes into fresh bags, not back into the drawer or the wardrobe the bugs may already have reached. If you are using a laundromat, bag everything both ways and do not tip a load out onto a folding bench.
- Keep sleeping in the bed. It feels wrong and it is the single most useful thing you can do. You are the reason they stay where they are.
- Do not shift to the couch. A week on the lounge usually buys you a second infested room and a much bigger job.
- Skip the stiff brush. Scrubbing a seam flicks eggs loose and scatters them rather than removing them.
- Interceptor cups are worth it. Smooth-sided traps under each bed leg catch what is walking to and from the bed and give you something countable.
- Write it down. Date, room and what you found. A fortnight of notes is genuinely useful to whoever treats the place.
- Pull the bed off the wall slightly but leave it in the same room, and keep bedding from touching the floor.
Do not throw the bed out yet. A mattress on the footpath spreads the problem down the street, and a brand new one goes into a room that still holds the population, so it is infested again within days. There is a separate guide to mattresses, bases and encasements covering when a bed is genuinely beyond saving.
The expensive mistake
Why do supermarket sprays and bombs make it worse?
Because the two products sold hardest for this insect do the one thing you must avoid: they scatter a population that was sitting in a handful of places you could have pointed at. Fogger mist lands where you can already see, so a tight joint, a bolt hole and the void behind a bedhead stay untouched, while survivors drift away from the smell along skirtings and under doorways.
There is an official warning behind this, not just trade opinion. State health guidance warns that a badly aimed space spray agitates these insects, triggers the alert pheromone they use to warn each other, and pushes the infestation out into areas that were clear. That is the mechanism: the chemical signal they give off when disturbed tells the rest of the group to leave, and they leave in every direction at once.
Eggs are the second half of the problem. Sprays may kill the insects they wet, but they are largely ineffective against eggs, which are glued into cracks and hatch over the following fortnight. A householder who sprays, sees nothing for ten days and then watches it restart concludes the bugs are indestructible. They are not. The treatment simply never touched the next generation.
Resistance is the third. Infestations have risen substantially in Victoria over the past decade, and the reason put forward by the state's own technical guidance is that modern bed bugs are highly resilient to many of the insecticides in common use. The actives in a supermarket aerosol are from that same family.
A single bedroom problem commonly turns up in the room next door and the lounge within a few weeks.
Scattered insects sit in new places with no established spotting, so the inspection takes longer.
More rooms and more hiding places means more preparation, more visits and a bigger bill.
Time is working against you while this plays out. A female lays two or three eggs a day and keeps going for months, so a fortnight of experimenting is a fortnight of growth. The product-by-product version of this argument, including what diatomaceous earth and alcohol really do, is in the honest rating of bed bug sprays.
The real job
What does a proper treatment look like from your side?
It is staged, not single. An inspection that maps where they actually are, a crack and crevice treatment aimed only at those places instead of a blanket coat over the room, then a return visit timed to the hatch. Your part is the preparation beforehand and, oddly, doing less cleaning than usual afterwards so the deposit left behind survives long enough to work.
| Stage | What happens | Your part |
|---|---|---|
| The day before | Nothing happens on site | Washing, bagging, clearing the floor, furniture left where it is |
| Treatment day | Inspection, then treatment into seams, joints, voids and edges | Be out for the re-entry period you are given, pets and kids included |
| First week | Numbers fall; the odd live insect is still normal | Sleep in your own bed, no extra spraying, no deep clean of treated edges |
| Around the follow-up | Eggs have hatched and the return visit deals with that generation | Report any new bite or sighting with the date and the room |
| Weeks three and four | The result becomes readable | Keep interceptors under the legs and check them weekly |
The follow-up is not an upsell. Victorian guidance is blunt that complete eradication is unlikely from one visit, that follow-up inspections are always required and that further treatments are often needed, because eggs can take up to a fortnight to hatch and sit in places nothing reaches on the first pass. A quote built around a single visit with no planned return is a quote for part of the job.
Two other things change the plan and are worth raising when you book. Adjoining rooms need checking once an infestation is confirmed, because by the time anyone notices, the room next door is often involved. And in a block of units, a neighbour's untreated flat will keep feeding yours, which usually means putting something in writing to the owners corporation.
What the visit covers, how the bed and bedding are handled, and how heat fits in for cluttered or repeat-failure rooms are set out on the bed bug treatment page. That is the point where this guide stops being enough.
Expectations
How long should it take, and what counts as success?
Judge it at the follow-up visit, not on day three. Bites usually ease within the first week or two, then there can be a short second flare as eggs hatch, which is expected rather than a sign of failure. A room is clear when nothing new turns up for several weeks: no fresh spotting, no insects in the interceptors, and no new marks appearing overnight.
Seeing a live one after treatment is normal. Seeing the same numbers a month later is not.
- Do not re-treat between visits. Shop-bought product laid over a professional deposit repels insects off the treated edges and cancels out the work.
- Go easy on the cleaning. Health guidance is to avoid vacuuming treated areas straight afterwards so the residue is not lifted.
- Keep the room in use. An empty bedroom pushes hungry insects to go looking for people elsewhere in the house.
- Count, do not guess. Interceptor cups and a dated note turn an argument about whether it is working into a number.
Be fair to yourself about the rest of it too. People raise the broken sleep and the dread far more often than the bites, and that part is real. These insects are not known to pass disease to people, the marks themselves are usually a localised itch, and the problem is solvable, which is worth repeating to yourself at three in the morning. If a bite looks infected or the reaction goes beyond local itching and swelling, that belongs with a pharmacist or a doctor rather than a pest control page, and the Better Health Channel entry on bedbugs sets out the usual advice.
There is a three month re-treatment guarantee behind covered work: find the same pest active again in those rooms within the window and Tim returns to treat them at no cost to you, on the terms set when the job was quoted. He holds Victorian pest control licence No. 86488, carries full insurance, and does every job himself across Melbourne and the suburbs roughly within a forty kilometre radius of town, rather than sending whoever is free.
If you want the treatment organised rather than another fortnight of reading, you can book a treatment and describe the room, which gets you a plan plus a figure to approve before any work starts.
Questions
Questions people ask about how to get rid of bed bugs
Can I get rid of bed bugs myself?
A very early find, one or two insects brought home in a bag and caught the same week, sometimes responds to hot laundering, thorough vacuuming and heat on the few items involved. An established population in a bed frame and skirting does not, because nothing sold retail reaches eggs glued into cracks.
Does having bed bugs mean my house is dirty?
No. They feed on people, not crumbs, so housekeeping has almost nothing to do with whether they arrive. Clutter matters only because it gives them more places to hide and makes treatment harder. Any household can be invaded, which is the wording Victorian health guidance uses.
Will one treatment be enough?
Usually not, and anyone promising it is glossing over the eggs. Official state guidance says complete eradication is unlikely in a single visit and that follow-up is always needed. Plan on a treatment and a return visit timed to when the eggs hatch, booked together rather than argued about later.
How long does it take to clear a room?
Most straightforward single bedrooms are readable within three to four weeks, counting the treatment, the hatch and the follow-up. Heavily furnished rooms, several rooms at once, or a flat under pressure from an untreated neighbour take longer. Judge progress at the return visit rather than in the first few days.
Should I throw out my mattress and bed frame?
Rarely, and almost never as the first move. A replacement bed goes into a room that still holds the population and is infested again quickly, and carrying an infested mattress through the house and down the street spreads it. Treat the room first, then decide what is genuinely beyond saving.
Can bed bugs live in a clean, empty room?
Yes. They can last months between meals, so an empty rental or a spare room that nobody uses can hold a quiet population waiting for someone to sleep there. That is also why moving out of a bedroom for a few weeks does not starve them out the way people hope.
Want someone to look at it properly?
Send Tim a photo of what you found and the room it came from, and you will get a straight read on whether it is bed bugs and what clearing them involves.
