If you’ve spotted fleas in your house, here’s the practical sequence to deal with them. This is the consumer-facing guide for Melbourne homeowners and renters: what to do today, what to do this week, and when to call a professional. Treatment cost across Greater Melbourne sits at $175-$300 if it gets to the professional stage. Most infestations do.
Key takeaways
- Day 1: confirm it’s fleas (white sock test, flea dirt check, bite location).
- Days 1-2: aggressive vacuuming, hot wash pet bedding, confirm pet preventative.
- Days 2-7: decide between DIY and professional based on infestation severity.
- DIY rounds typically total $150-$250 with no guaranteed result; professional treatment runs $175-$300 and clears in one visit.
- Most common mistake: treating the pet only and ignoring the home environment.
Day 1: confirm what you’re dealing with
Before you start spending money, confirm it’s actually fleas and not something else (bed bugs, mosquitoes, dust mites).
Three signals together mean fleas
- Itchy red bites in clusters of 3-4 on your ankles or lower legs (fleas can’t jump higher than 30cm reliably)
- Pet scratching more than usual despite being on flea preventative
- Small black specks (flea dirt) in pet bedding, along skirting boards, or anywhere the pet rests
The white sock test
Walk slowly across carpet wearing white socks. Adult fleas jump onto the socks within 30 seconds. If you see them jumping, you have an active infestation, and the population in the carpet is much larger than what’s visible.
Days 1-2: immediate damage control
A few things help right away. None of these will clear the infestation alone but they reduce the bites and start dropping the population.
Vacuum aggressively
Carpets, rugs, soft furnishings, under furniture, along skirting boards, pet bedding. Use the beater bar. Empty the canister or bag into an outside bin straight after each session. Vacuuming agitates the cocooned flea pupae and stimulates them to emerge as adults, which makes them vulnerable to whatever comes next.
Wash pet bedding
Hot wash (60°C+). Tumble dry on high heat to kill any survivors. If you can’t hot wash it, replace it.
Confirm pet preventative
Confirm your pet is on a working flea preventative. The vet-prescribed options (NexGard, Bravecto, Advantix, Comfortis) are all reasonable. Supermarket flea collars are usually less effective. The pet preventative kills any flea that bites the pet, but it doesn’t treat the home environment.
Days 2-7: deciding between DIY and professional
This is the decision point. Your options:
DIY supermarket sprays
Cost $30-$60 per round. Kill adult fleas on contact but don’t include an insect growth regulator (IGR), so eggs survive and hatch. Most users go through 3-4 rounds totalling $150-$250 with no guaranteed result. Worth trying ONLY if you’ve caught the infestation very early.
Salt and bicarb
Cost basically nothing. Dehydrates adult fleas in the immediate area but doesn’t reach larvae or pupae. Useful as part of a multi-step plan, ineffective alone.
Diatomaceous earth
Cost $20-$30 per bag. Works on adults and some larvae over 2-7 days. Has to be reapplied after vacuuming. Better than salt, weaker than professional.
Professional flea control
Cost $175-$300 in Melbourne. Uses adulticide plus IGR (the IGR is what no household product includes). Targets carpet pile, skirting boards, soft furnishings, pet bedding. Residual product runs 8-12 weeks. Clears the infestation in one visit in most cases.
The honest cost comparison: a typical Melbourne household that doesn’t deal with fleas properly the first time spends $400-$700 across DIY attempts plus an eventual professional visit. Booking the pro first time is faster and usually cheaper.
Common mistakes that make the problem worse
Three mistakes Melbourne households make repeatedly.
1. Treating the pet only
The pet preventative kills fleas that bite the pet. The eggs already in the carpet still hatch. New adults emerge for weeks. Treat the home environment too.
2. Skipping the outdoor source
If you have a yard and pets that go outside, fleas hitch a ride back inside. Indoor treatment without outdoor add-on means re-infestation within 4-6 weeks. We cover this in detail in our outdoor flea control guide.
3. Vacuuming after professional treatment
The residual product needs 7-10 days in the carpet pile to kill late-emerging adults from cocooned pupae. Vacuuming strips the residual out. Hold off vacuuming for the first week after the pro visit.
When to call a professional
The signs you’ve passed the DIY stage:
- Bites continuing for more than 7 days despite vacuuming and DIY treatment
- Multiple household members getting bitten
- Pet scratching despite preventative
- Visible adult fleas every time you do the white sock test
- A returning issue 2-3 weeks after a previous DIY round (this is the cocooned-pupae cycle)
Frequently asked questions
How long does it take to clear an infestation?
With professional treatment, 2-3 weeks. The first 5-7 days you’ll actually see MORE fleas as cocooned pupae emerge, then the residual product kills them. By week 3 it’s clear.
Do I need to leave during treatment?
Out of treated rooms for 2-4 hours while the spray dries. You can stay in untreated areas (kitchen, bathroom) during that window.
Can fleas live without a pet host?
Adult fleas need a blood meal to reproduce, but they can survive 1-2 weeks without one. Pupae can sit dormant for months. So an empty house with no pets can still re-infest a new tenant.
Will fleas bite babies and young children?
Yes. Children’s lower body height puts them in flea range more often. Reactions can be larger than adults’ bites because their immune systems are still developing.
