Highly venomous tiger snakes may seek shelter from summer heat under debris in the garden, says
In suburbs with rocky, overgrown gardens, fish ponds and river frontage, from south-eastern Queensland to southern Tasmania, one of the most dangerous land snakes in the world is on the prowl. Growing to 2m long, sporting yellowish bands on a brown, olive or black background, the formidable eastern tiger snake produces venom four times as powerful as the Indian cobra’s, and makes it in significant quantities. Small animals succumb very quickly to the venom, but larger animals, such as rabbits, are constricted by the snake to prevent them escaping before the venom takes effect.
Frogs are the tiger snake’s primary prey, but frog numbers have plummeted as swamps are drained for agriculture and land development, forcing tiger snakes to adapt to new urban landscapes. Snakes even pop up in downtown metropolitan areas, probably carried as stowaways in cars or delivery vehicles.
As summer temperatures soar, tiger snakes adjust their routines to avoid overheating, sheltering in abandoned burrows or under rocks, logs and other surface debris during the day. Discarded tin sheets, household items and woodpiles are perfect habitats for snakes. It’s always a good idea to keep grass short and block holes in rock walls and around the house to eliminate hiding places.
Tiger snakes hunt at night in summer, so if you’re walking around in the evening, it’s wise to take a torch and wear long trousers and good footwear. If you do cross paths with a snake, freeze, and retreat slowly. Never attempt to catch or kill a snake, as
the vast majority of snakebites happen when someone tries to pick up a snake or kill it.
The good news is tiger snakes roam over large areas and are unlikely to take up residence in your garden. They are also shy and prefer escape over conflict. Fatal snake bites are extremely rare. Snakes often dry-bite, preferring to keep their precious venom for their prey. Also, it’s good to know that antivenene is widely available.
