Who pays for pest control in an Australian share house — tenants or landlord?

It depends on the cause. If pests were there before you moved in or are caused by building issues, the landlord pays. If the infestation is caused by tenants — dirty kitchen, food waste, poor hygiene — tenants pay. In practice, many landlords will cover it regardless to protect their property.

How often should a share house get pest control?

Once or twice a year is standard for most Australian share houses. Do a general spray before summer when cockroaches are most active. If you're in a ground-floor apartment or an older house, twice a year is worth the money. It's a lot cheaper than dealing with a full infestation.

Should all housemates pay for pest control equally?

For a whole-house treatment, yes. Everyone lives there, everyone benefits from a pest-free home, and the cost per person is small enough that equal is the fairest approach. The only exception is if one person's habits directly caused the infestation, in which case have an honest chat.

How much does pest control cost in Australia?

A standard cockroach and ant spray costs $150 to $200 for a typical share house. Termite inspections run $200 to $350. Rodent treatments are $200 to $400 depending on severity. Split three ways, even the priciest option is under $135 per person.

Do you need pest control before moving out of a rental?

Check your lease. Many Australian rental agreements require a professional pest control treatment at the end of the tenancy, especially if you had pets. If it's in the lease, you need the receipt to get your bond back. Budget $150 to $250 for an end-of-lease treatment.

Can you claim pest control costs back from the landlord?

If the pest issue was the landlord's responsibility and they refused to act, you may be able to claim the cost back through your state's tenancy tribunal. Document everything — photos, communication with the landlord, and the pest controller's report. Most states have a straightforward process for this.

How to Split Pest Control With Your Housemates

If you live in a share house in Australia, you will encounter cockroaches. That's not a maybe — it's a when. And when the inevitable happens and someone suggests calling pest control, the next question is always the same: who pays for it? Here's how to sort it out without the whole house losing their minds.

How to Split Pest Control Fairly

1

Check if it's the landlord's problem

In most Australian states, landlords are responsible for pest control if the infestation existed before you moved in or is caused by building issues like gaps in walls or broken seals. Check your lease and your state's tenancy laws. If the landlord's responsible, don't pay for something that's not your problem.
2

Get quotes from pest controllers

Don't just go with the first company you find. Get two or three quotes for the specific treatment you need. A basic cockroach and ant spray runs $150 to $200. Termite inspections are $200 to $350. Ask what's included and whether there's a follow-up treatment.
3

Agree on the split

If it's a house-wide treatment, split the cost equally between all housemates. If the issue is isolated to one person's room — say, someone left food out and attracted ants — have a conversation about whether the cost should be shared or whether that person contributes more.
4

Book and pay

One person books and pays the pest controller, then logs the expense in Split. The cost gets divided according to whatever you agreed on. Most pest controllers want payment on the day, so the person booking it needs to be ready to front the cash.
5

Schedule future treatments

In most parts of Australia, annual pest control is a good idea. Set a reminder for the same time next year and budget for it. Knowing the cost is coming means nobody's blindsided, and regular treatment is cheaper than dealing with a full-blown infestation.

Ways to Split Pest Control

Method	How It Works	Best For	Fairness
Equal split	Total pest control cost divided equally between all housemates.	Whole-house treatments like a general spray or termite inspection. Everyone benefits, everyone pays.	High
Usage-based	If the pest issue is caused by one person's habits — leaving food out, not cleaning their room — they pay a larger share.	Situations where one housemate's behaviour directly caused the problem. Handle this diplomatically.	Medium
Income-based	Pest control cost split proportional to each housemate's income.	Houses with a big earning gap where a $200 bill hits differently for different people.	High
Landlord responsibility	The landlord pays the full cost. Tenants pay nothing. Applicable when the infestation is a pre-existing condition or caused by building defects.	Any situation where the pest issue isn't the tenants' fault. Know your rights — many Australian tenants pay for pest control they don't have to.	High

Tips for Splitting Pest Control

Know your tenancy rights

In NSW, VIC, and QLD, landlords must ensure the property is reasonably free of pests at the start of a tenancy. If cockroaches were there before you moved in, the landlord should foot the bill. Check your state's residential tenancy authority website.

Prevention is cheaper than treatment

Keep shared areas clean, take the bins out regularly, don't leave food scraps on the bench, and seal any gaps around pipes. A clean share house won't eliminate pests entirely, but it'll reduce how often you need to call someone in.

Get a receipt for bond purposes

Some leases require pest control before you move out, especially for flea treatment if you had pets. Keep the receipt — you might need it to get your bond back. If the lease says you need to do it, budget for it as part of moving costs.

Don't DIY for serious infestations

A can of Mortein handles the occasional cockroach, but a proper infestation needs professional treatment. DIY sprays from Bunnings might push pests into the walls temporarily without actually fixing the problem. Spend the money on a professional and do it properly.

Budget for it annually

Pest control isn't a surprise expense if you plan for it. Set aside $50 to $70 per person per year for an annual treatment. Add it to your share house budget at the start of the lease so nobody's caught off guard when the cockroach population explodes in summer.
