If you live in South East Queensland, you already know that cane toads are a year-round reality. But there are times of year when numbers spike, when the risk to your pets is significantly higher, and when you need to be actively managing your property rather than hoping for the best.
Understanding cane toad season — what drives it, when it peaks, and what it looks like on the ground — helps you stay ahead of it.
When Is Cane Toad Season?
Cane toads do not have a single, discrete season the way some pest species do. They are present in most of South East Queensland throughout the year. What changes with the seasons is their level of activity, their breeding behaviour, and their numbers.
Peak activity: October to April
This aligns with Queensland's wet season. Warm temperatures above 20°C combined with humidity and rainfall create near-ideal conditions for cane toad breeding and feeding. During this period:
- Adult toads are highly active from dusk onwards
- Breeding activity intensifies near any water source
- Tadpole development is rapid, producing new adult toads within weeks
- Numbers on any given property can increase significantly after a single heavy rain event
Lower activity: May to September
Cooler and drier conditions slow toads down. They become less mobile, feed less frequently, and breed less actively. In South East Queensland however — particularly on the Gold Coast, Brisbane, and Sunshine Coast — winters are mild enough that toads remain active on warm nights year-round.
Do not assume winter means no risk.
What Drives the Spike in Numbers
Three factors drive cane toad population surges during the wet season:
Rainfall. Rain is the single biggest trigger. A good downpour causes adult toads to emerge in numbers from their daytime shelters and move toward water sources to breed. If you live near a creek, dam, pond, or any low-lying area, heavy rain can be followed within days by a noticeable increase in toad activity.
Temperature. Cane toads are ectotherms — their body temperature is regulated by the environment. Warm nights above 20°C keep them active for longer. The combination of warm nights and rainfall is when you will see the highest numbers.
Breeding cycles. A female cane toad can produce up to 30,000 eggs in a single clutch, and breed multiple times per season. Those eggs hatch into tadpoles within two days in warm water. Tadpoles become toadlets — small enough to be easily missed — within four to six weeks. This rapid breeding cycle means a large rainfall event in October can translate into a visible population increase by December.
What to Expect During Peak Season on the Gold Coast and Brisbane
In South East Queensland, peak season typically looks like this:
October–November: Toads become noticeably more active after the first significant rains. Numbers start to build. This is the time to assess your yard, identify entry points, and act before populations establish.
December–February: Activity is at its highest. Toads are active most nights. Any yard with a water feature, garden, or sheltered areas will likely have resident toads. The risk to pets is at its greatest during this period.
March–April: Activity begins to ease as temperatures stabilise and rainfall becomes less consistent. Toad numbers remain high but start to decline.
May–September: Activity drops noticeably. Toads are still present but less visible. This is a good window for professional removal and to consider barrier fencing installation before the following season.
The Risk to Pets During Peak Season
The overlap between cane toad activity and pet behaviour is what makes the wet season so dangerous.
Toads are most active from dusk to midnight. Dogs and cats are often let outside in the evening. Toads shelter under outdoor furniture, pot plants, garden beds, and along fence lines — exactly where pets investigate.
During peak season, a single evening in the backyard is enough time for a contact to occur.
This is not about careless pet owners. Most families who experience a toad poisoning incident knew the risk existed. The problem is that the risk can feel abstract until the night it is not.
How to Prepare Before the Season Starts
The best time to act is before peak season, not during it.
Reduce habitat. Remove ground-level clutter — timber piles, debris, overgrown garden beds — that toads use as daytime shelters. Keep grass cut short. Remove any standing water that is not essential.
Remove food sources. Outdoor pet food bowls, uncovered compost, and insect attractants (such as outdoor lights left on all night) draw the insects that toads feed on. Remove them.
Check your yard at dusk. Walk the perimeter with a torch before letting pets out in the evening during peak season. Remove toads you find using a thick rubber glove and dispose of them according to RSPCA guidelines.
Consider barrier fencing. Our PetSafe Barrier fencing is designed to physically exclude toads from entering your yard at ground level. Installation is most practical between May and September, before the next peak season begins.
Book a professional removal. A professional toad removal service can significantly reduce the resident toad population on your property. Combined with habitat reduction, it gives you a much lower baseline heading into peak season.
What About Tadpoles?
Cane toad tadpoles in garden ponds, dams, and water features are a sign that you have toads actively breeding on or near your property. Each clutch left untreated means dozens to hundreds of new adult toads within weeks.
Tadpole trapping is one of the most effective ways to break the breeding cycle before it compounds. If you have a water feature that regularly attracts toads, this is worth addressing before October.
