When you think about intruders in your home, your mind probably jumps straight to a masked man wielding a crow bar. But there are other intruders that many of us are keen to keep outside too. Creeping, crawling, walking, jumping, slithering, sliding and flying intruders! In a country with over 500,000 insect species and countless other creatures, it’s no wonder so many people choose to install security screens on windows and doors. Let’s take a look at the most common critters that come to visit Aussie homes to annoy, scare and even harm us. Mosquitos The award for most annoying insect would probably go to the humble Aussie mozzie. It’s easy to think the worst they can do is give you an annoying itch to scratch, but the truth is mosquitos can do far worse. Even here in Australia they can carry debilitating diseases including Murray Valley encephalitis virus, Ross River Virus, Barmah Forest Virus and Dengue Virus. Your best defence is often to cover up with repellant outdoors, and try your best to keep them outside your home with screens on your windows and doors. Flies If you live in Australia, you’ll know what it’s like to spend a BBQ chasing flies away from your steak and snags. It’s not fun. And it’s not too healthy either. Flies don’t just drive you crazy – they can easily send you to the sickbay with food poisoning! If you’d like a detailed explanation of exactly how and why this happens, check out this video. But we’ll warn you, it’s a pretty gross reality. What Really Happens When A Fly Lands On Your Food. Spiders When it comes to 8-legged intruders, Australia is a world class contender with many of the most venomous spiders on the planet calling the land down under home. But let’s be honest, they aren’t all crawling around in our suburbs, nor can a security screen keep every one of them out. But one thing is for sure. With security screens on every window and door you’ll be less likely to get a frightening visit from the bigger, hairier ones! Take the legendary Huntsman for example. Love them or hate them, these critters really cause a commotion once they get into a home. Here’s what happened when an American family in Australia were paid a visit by a big specimen! Snakes It seems like every couple of weeks we see a story on the news about another snake crawling its way into an Australian home. They get stuck in toilets, they hide in cupboards and under beds, and sometimes they go searching for food! To say that finding a 10 foot python under your lounge is an unnerving experience is the understatement of the year. But it’s the often smaller, far more venomous varieties that are the real worry. Especially if you have pets or children in your home. The good news is there’s no way a snake can bust its way through a Crimsafe screen! Cats Cats are curious creatures. They also happen to like picking fights with other cats and hunting around for food. That’s three good reasons to think about putting security screens on your windows and doors. It’s not just about keeping other cats out either! There’s a good argument for cat-owners to keep their feline friend securely inside at night to help protect our native flora and fauna.
