Have you ever spotted a spider lurking in the corner of your ceiling and wondered how it got there? Spiders are a common sight in Perth homes, especially during the warmer months when they’re seeking shelter or hunting for insects. While many species are harmless, some can cause alarm or even pose a health risk to families. The key to keeping them out is understanding why they appear and how to prevent them. At Stewarts Pest Control , we’ve been helping Perth homeowners with effective spider pest control since 1954, using trusted methods to keep homes safe, comfortable, and spider-free all year round. The Most Common Spiders Found in Perth Homes Perth is home to a wide variety of spiders, most of which play an important role in controlling other household pests. However, some species can become unwelcome guests when they move indoors in search of warmth or food. Knowing which spiders are most common around Perth homes helps you identify potential risks and take the right steps for safe spider control. Redback Spider Perhaps the most recognised spider in Australia, the redback is notorious for its venomous bite. Easily identifiable by the red stripe running down its shiny black abdomen, the redback prefers dark, sheltered areas like garden sheds, outdoor furniture, mailboxes, and underneath toys or equipment. Females are more dangerous than males, and their webs are messy, sticky, and often found in dry corners. While bites are rare and usually occur when the spider is disturbed, redbacks should always be handled by professionals. White-Tailed Spider The white-tailed spider is a common intruder, often found indoors at night. They tend to wander into homes searching for other spiders to prey on. They’re typically found in clothing, bedding, or towels left on the floor, which can lead to unpleasant surprises. Contrary to myths, their bites rarely cause serious harm, but they can be irritating and painful. Huntsman Spider Large, fast, and frightening at first glance, the huntsman spider is mostly harmless. These spiders are often found on walls or ceilings and may enter homes seeking warmth or insects to feed on. Despite their size, huntsmen are beneficial because they reduce the number of flies, cockroaches, and moths indoors. Black House Spider These dark, compact spiders often build dense, funnel-like webs around window frames, eaves, and fences. While they rarely bite, their webs can attract other insects, which in turn draw more spiders to the area. Daddy Long Legs Recognisable by their delicate, long legs and small bodies, daddy long legs are common in corners of ceilings and garages. They’re harmless and even feed on other spiders, but their webs can quickly accumulate and make a home look untidy. Understanding which spiders are present in your home helps you take the right preventive measures and seek professional help when needed, ensuring a safe and spider-free environment. Why Spiders Enter Homes Even though most spiders prefer to stay outdoors, Perth homes often provide the perfect environment for them to thrive. Understanding why spiders come inside is the key to keeping them out. From shelter and warmth to readily available food sources, several factors can make your home inviting to these eight-legged visitors. Seeking Shelter from the Elements Spiders are sensitive to changes in temperature and weather. During hot summers or heavy rains, they often move indoors to escape the harsh conditions. Cracks around windows, vents, and door frames become easy entry points. Once inside, spiders hide in undisturbed areas such as basements, roof spaces, cupboards, or behind furniture where they can build webs safely. Hunting for Food Sources One of the most common reasons spiders enter homes is the abundance of insects. Flies, mosquitoes, and ants serve as their primary food sources, and homes with other pest issues are more likely to attract spiders. By keeping kitchens and outdoor areas free from leftover food and crumbs, you reduce the overall insect population, and in turn, the number of spiders. Breeding and Nesting Spiders reproduce quickly, and a single egg sac can contain hundreds of spiderlings. These baby spiders often spread throughout the home, settling into quiet corners or ceiling spaces. Regular cleaning and decluttering disrupt their nesting spots, helping to prevent future infestations. Light and Warmth Outdoor lights attract insects at night, which naturally draws spiders closer to entry points like windows and doors. Reducing unnecessary lighting or using yellow “bug-safe” bulbs can help minimise this problem. While these habits explain why spiders seek refuge indoors, removing them completely often requires more than cleaning alone. Professional spider removal services target the root of the problem, not just visible webs, ensuring your home remains clean, comfortable, and spider-free. Effective Prevention Tips to Keep Spiders Away Keeping spiders out of your home doesn’t have to be difficult. By combining good housekeeping habits with a few simple maintenance steps, you can create an environment that’s far less appealing to them. Prevention is always more effective and affordable than dealing with an active infestation. Seal Entry Points and Cracks Spiders are experts at squeezing through tiny gaps. Inspect your home’s doors, windows, and skirting boards regularly for cracks or openings. Seal them with caulk or weather stripping to block potential entry points. Don’t forget to check vents, utility lines, and under-door gaps; these are often overlooked yet common access routes. Keep Your Home Clean and Clutter-Free Spiders prefer quiet, dark corners where they won’t be disturbed. Regular vacuuming, especially in corners, behind furniture, and along ceiling edges, helps remove webs, egg sacs, and insects that spiders feed on. Avoid clutter buildup in garages, sheds, and storage rooms, as cardboard boxes and stacked items make ideal hiding spots. Reduce Outdoor Attractants Your garden can be a launching pad for spiders to enter the house. Trim back shrubs and plants that touch external walls or windows, as they provide bridges for spiders to cross. Keep garden beds tidy and avoid leaving piles of wood or debris near your home’s foundation. Outdoor lighting should also be minimised, as bright lights attract insects that, in turn, attract spiders. Use Natural Deterrents Wisely Simple natural remedies can complement regular cleaning. Peppermint, citrus, or eucalyptus oil diluted with water can be sprayed around windowsills, corners, and door frames to discourage spiders. While these solutions don’t eliminate infestations, they help deter new arrivals when used consistently. Schedule Regular Inspections Even the most diligent homeowner can miss hidden spider nests. Regular inspections by professionals ensure potential problems are caught early. A licensed technician can identify spider types, remove webs, and apply safe treatments designed for long-term protection. By taking proactive steps and maintaining these habits year-round, you can enjoy peace of mind knowing your home remains clean, comfortable, and spider-free. When to Call the Professionals While prevention goes a long way, there are times when professional help becomes essential. Some spider infestations are simply too widespread, too persistent, or too risky to handle on your own. That’s when calling in experts can make all the difference in restoring comfort and safety to your home. Recognising the Signs of a Larger Problem If you’re constantly noticing webs reappearing shortly after cleaning, spotting spiders in multiple rooms, or finding egg sacs around the property, it may indicate a larger issue. Spiders reproduce quickly, and a single female can lay hundreds of eggs. Once this happens, the infestation can grow faster than most home remedies can manage. Other red flags include seeing venomous species such as redbacks or white-tailed spiders near living spaces, especially if children or pets are present. These cases call for immediate professional attention to ensure safety and proper treatment.
