Once a year? Every season? Only when you see pests? Here is how often Melbourne homes actually need pest control, based on your property, suburb, and pest history.
The Short Answer
For most Melbourne homes, a professional general pest treatment every 12 months keeps cockroaches, spiders, and ants under control, paired with an annual termite inspection. Homes with recurring problems, pets, nearby bushland, or past infestations do better on a 6-monthly schedule timed for spring and autumn. Here is how to work out where your home sits.
Why Treatments Do Not Last Forever
A professional treatment leaves a residual barrier that keeps killing pests for months - but sun, rain, and time break it down, typically over 6-12 months outdoors. Meanwhile Melbourne's seasons keep sending new waves: termite swarms and ants in spring, wasps and spiders in summer, rodents moving indoors in autumn. An expired barrier plus a new season's pests is how "we never used to have problems" homes suddenly do.
Annual Treatment: The Baseline
A once-a-year general pest treatment suits most established homes with no special risk factors. The ideal timing is early spring - the barrier is freshest through the peak pest months. Add the annual termite inspection that every Melbourne home needs regardless (most termite warranties require it).
When 6-Monthly Makes More Sense
- Past infestations - cockroaches, ants, or rodents that have established once tend to return
- High-pressure locations - near creeks, reserves, bushland, paddocks, or cafés and food strips
- Older homes - more gaps, subfloors, and roof voids for pests to exploit
- Pets - flea cycles and pet food attract more activity
- Heavy seasonal invaders - suburbs plagued by millipedes, earwigs, or spiders each autumn and spring

What About Businesses?
Food businesses are a different story: health inspectors and HACCP require an ongoing documented program, typically monthly or bi-monthly service with logbooks and reports. See our commercial pest control programs.
Waiting Until You See Pests Costs More
Reactive pest control means the infestation is already established - which usually means multiple visits, more product, and more damage. Preventative treatment is cheaper per year than fighting an established German cockroach or rodent problem, and infinitely cheaper than the termite damage an annual inspection would have caught. Our guide to pest control costs in Melbourne breaks down the numbers.
A Simple Schedule That Works
- Every home: general treatment each spring + termite inspection annually
- Higher-risk homes: add an autumn treatment before rodent season
- After any infestation: follow-up as advised, then 6-monthly for the first year
