Why Torrential Downpour Leads to a Spike in Household Pests

Torrential downpours are an unfortunate and common occurrence in South East Queensland, bringing along a long list of complications. Particularly, an especially lousy side-effect of flooding that most homeowners don't realise beforehand, is a spike in household pests. From creepy crawlies to rodents to snakes - these guys tend to be desperate for shelter from harsh rain and destroyed dwellings.

Perhaps you've noticed colonies of ants sneaking into your family room or spiders starting to build webs on your veranda instead of in your garden. Whatever the case might be, it's clear that the number of pests in residential areas soar when it rains, with these critters becoming a lot closer than comfort to humans with a simple reason why. Given that the majority of pests reside outside, when it rains it usually flushes away their established homes, filling nesting holes with water, tearing webs apart, and lifting underground insects towards the surface. So, not only do these pests have nowhere to reside, but it also makes them easier to spot by predators (this is why birds may hang around your backyard after it rains), which means these critters need somewhere to take cover, and what better place than your Nambour home?

Here at K.C.S, we care about your residence's protection against pests, so we've created a quick list of common household pests to watch out for during flooding:


Mosquitoes are notorious for breeding exceptionally fast when it rains due to their preference for stagnant water. Look out for mosquito populations increasing as they can carry zoonotic diseases.


As aforementioned, ants hate the rain due to the destruction of their hills, meaning these guys will look for any shelter available to them.

Mice and Rats

Rodents tend to be significantly more sensitive than other pests when it cans to any external stimuli, including rain, and use their sharp teeth to bite into household infrastructure or cars to get covered. It's especially vital to take caution if you notice an increase of rodents on your Nambour property, as they can be followed by their number one predator - snakes.


Even the strongest of spider webs can be easily torn from heavy rainfall, so it's safe to say that spiders such as huntsman, daddy-long-legs, or even red-backs are interested in sharing your space.


Although cockroaches love moist environments, heavy rainfall tends to have them looking for drier accommodation, so be on the lookout and cover open sources of food.
