How to Keep Dangerous and Nuisance Spiders Out of Your Home

Have you ever walked into a room only to find a large spider on the wall or hanging from the ceiling? It’s a heart-stopping moment many Perth residents have experienced. While some spiders are harmless and even helpful in controlling other insects, others can pose real health risks, especially to children and pets. Whether it’s venomous bites or unwanted webs in every corner, spiders are a common nuisance that homeowners would rather live without.

Perth is home to a range of spider species—some harmless, others potentially dangerous. Knowing which ones you're dealing with is key to managing them effectively.

The most common spiders in Perth include:

• Redback Spiders: Easily identified by the red stripe on their back, these spiders favour dry, sheltered areas such as garden sheds, underneath furniture, or kids’ play equipment. Their bite can be harmful, especially to young children or the elderly.

• White-tailed Spiders: Known for their speed and their painful bites, these spiders are nocturnal hunters that often enter homes in search of prey.

• Black House Spiders: These shy spiders build messy webs around windows, eaves, and fences. While not aggressive, they will bite if provoked.

• Huntsman Spiders: Large and fast, these are usually more of a scare than a threat. They rarely bite and are often found behind curtains, wall hangings, or in cars.

Each spider has its own habits, preferred hiding spots, and risks. At Stewart Pest Control, our technicians are trained to identify the species and customise treatments accordingly—a vital step in effective spider pest control in Perth.

While not every spider poses a risk to humans, Perth is home to several species with potentially harmful bites. Understanding which spiders are dangerous and recognising them in your home is crucial for your safety.

Potentially dangerous spiders in Perth include:

• Redback Spiders: A bite from a female redback can cause severe pain, sweating, nausea, and in some cases, hospitalisation. They are commonly found in dark, sheltered outdoor areas like under furniture, bins, or eaves.

• White-tailed Spiders: Although their venom is not considered lethal, bites can lead to localised pain and swelling. In rare cases, they have been linked to skin irritation and ulceration.

Even seemingly harmless spiders can become a problem. Their presence often causes distress, especially for those with arachnophobia, and their webs can make homes appear untidy. Families with small children or curious pets should be particularly cautious, as accidental encounters can happen quickly.

It’s worth noting that spider bites in Perth are relatively uncommon when homes are properly maintained and treated. Still, any suspected bite should be monitored, and medical attention sought if symptoms worsen.

When in doubt, it’s best to leave spider identification and control to the professionals. Stewart Pest Control offers thorough inspections and targeted treatments to eliminate risk and restore comfort.

If you’ve noticed an uptick in spider activity lately, you’re not imagining things. Several environmental and behavioural factors contribute to increased spider presence in and around Perth homes.

Top reasons for spider sightings:

• Seasonal patterns: Warmer months encourage spider breeding, making late spring and summer peak times for infestations.

• Weather changes: Heavy rain or sudden temperature drops can drive spiders indoors seeking shelter.

• Prey availability: A rise in insect populations around your home will naturally attract more spiders looking for a meal.

• Shelter and nesting spots: Spiders love cluttered areas like garages, sheds, and under outdoor furniture. Indoors, they favour ceiling corners, behind furniture, and in wardrobes.

• Unsealed entry points: Gaps under doors, cracks in walls, and torn fly screens provide easy access for spiders to enter.

In some cases, a single female spider can produce hundreds of spiderlings, causing a rapid increase in numbers if left unchecked. Additionally, outdoor lighting can attract flying insects at night, which in turn lures spiders to those areas.

Spiders are opportunists. If your home offers food, warmth, and hiding spots, they'll settle in comfortably. Fortunately, you can change that with the right approach—starting with regular inspection and targeted prevention strategies.

When homeowners spot spiders, their first instinct is often to reach for a can of insect spray. While this might eliminate a visible spider or two, it rarely solves the root of the problem.

Here’s why DIY spider control often fails:

• Surface sprays don’t reach nests: Many spiders build their webs in hard-to-reach areas. Spraying visible areas won’t address the hidden egg sacs or webs tucked away in cracks and crevices.

• No long-term protection: Most off-the-shelf products offer only temporary relief, requiring frequent reapplication without lasting results.

• Inaccurate identification: Using the wrong method for the wrong spider species can be ineffective or even dangerous.

• Missed hot spots: Without a trained eye, it’s easy to overlook where spiders are truly hiding and breeding.

Some homeowners even make the problem worse by disturbing nests and triggering spiderlings to spread to new locations. Others risk bites by trying to capture or kill venomous spiders themselves.

Even after professional treatment, taking proactive steps can make a huge difference in keeping spiders away.

Here are some practical prevention tips:

• Declutter regularly: Reduce storage in sheds, garages, and spare rooms where spiders love to hide.

• Seal cracks and gaps: Check doors, windows, skirting boards, and walls for entry points.

• Limit outdoor lighting: Reduce the number of lights left on at night or switch to yellow-toned bulbs that attract fewer insects.

• Maintain garden areas: Trim back vegetation, rake leaf litter, and remove piles of wood or debris near the house.

• Vacuum frequently: Clean ceiling corners, behind furniture, and other secluded areas where spiders may build webs.

• Check furniture and boxes: When bringing items in from storage or the shed, give them a quick shake or inspection first.

You can also install door sweeps and repair flyscreens to physically block entry. Keeping your home well-maintained is one of the most effective deterrents for pests of all kinds—especially spiders.

If you find a new web appearing every day or consistently see spiders in the same areas, it’s time to consider professional spider removal.
