With the wet weather and flooding becoming a common occurrence, unwelcome visitors have unfortunately surfaced, especially in the homes of Sydney residents. Pests such as rats, mice, snakes, spiders, termites, and ants are looking for new places to make their homes. When areas get flooded, animals look to find places that are less saturated with water and often try to find higher ground, which can unluckily include your backyard or even inside your home.

If you're finding that certain animals have decided to set up camp in your home, we've provided some advice to help you shoo them out.


  • Snakes usually seek out structured places such as storage sheds or garages when they need to find a new home.

  • If you find a snake in your backyard, don't come into contact with it. Move back and let it continue on its way.

  • Wear long pants, boots and gloves when handling debris and make sure the debris is removed as quickly as possible to avoid infestation of rats or lizards which snakes feed on.

  • Cut down any overhanging tree branches, as snakes can climb up them and gain access into your backyard.

  • If you find a snake inside your house, contact a snake catcher who can properly remove it from the area.


  • Flooding and wet weather can cause ants to seek shelter in homes, latching onto dry surfaces.

  • According to researchers, ants physically cling to one another in order to float on floodwater and then proceed to attach to surfaces that are above the water.

  • To prevent an invasion of ants in your home, keep surfaces clear of food debris, seal any gaps or cracks to reduce ants coming in or use ant baits.

Rats and Mice

  • It's important that rats and mice are kept away as they can spread illnesses such as Leptospirosis, rat bite fever and salmonellosis due to disease-transmitting microorganisms found in their urine and droppings.

  • Once set up in a new place, rats and mice will breed and establish themselves in the area, with their gestation period being between 19 to 21 days.

  • Some of the warning signs that rats may be in your home include, gnawed objects, brown or black rub markings or smudges as well as droppings and urine marks.

  • In order to avoid an infestation of mice it's important to remove any food that may attract them as well as covering up bins. Place rodent baits or traps in dry places where pets and young children cannot reach them.

  • If you live in the southwest suburbs of Camden, Oran Park, and Narellan in New South Wales, exterminators have reported an increased invasion rate of rats.


  • Unlike other pests, termites do not seek out higher ground in order to avoid drowning. They can in fact live underwater for up to 16-30 hours while in an immobilised condition which saves oxygen.

  • Termites are attracted to moisture and so are more inclined to seek out wet conditions, especially after flooding occurs.

  • Some telltale signs of a termite infestation include hollow timber and cracked wood, mud tunnels, and any termites that are residing in your garden as they could have already travelled into your home. An uneven floor may indicate that there are termites hiding underneath and if you notice any mounds or nests in trees this could mean that termites are present.
