Our Spider Treatment in Perth
Internal, External, and Hidden Harbourage Areas
At Pest M8 we don't just spray the skirting boards and call it done. Our spider treatment in Perth is methodical and thorough, covering every area where spiders live, breed, and hide.
Roof void treatment
Where possible, we dust the roof void with a growth regulator. This is one of the most overlooked areas in a standard spider treatment, yet it is one of the most active harbourage zones, particularly for redbacks and black house spiders.
Inside the home
Internal areas are treated as required, targeting corners, skirting boards, behind furniture, and any visible webs or egg sacs. We treat with your family's safety in mind, using products that are effective against spiders but safe once dry.
Subfloor treatment
If your property has a subfloor accessible via vents, we treat this area too. Subfloors are dark, sheltered, and rarely disturbed, making them a prime habitat for redbacks and other ground-dwelling species.
External perimeter
We spray the perimeter of the property one metre up around all exterior walls. This creates a treated barrier that intercepts spiders before they find a way inside.
Doors and window frames
Entry points are a priority. We spray all door frames and window frames to stop spiders using gaps and seals to get in.
Paths and garden edges
Paths, garden borders, and landscaped edges are treated to reduce the spider population in the areas your family uses most.
Eaves and gutters
We treat these prime real estate for spiders, targeting both the structures themselves and any existing web sites.
Fence line and capping
The fence line, including fence capping, is treated to reduce spiders migrating from neighbouring properties or from garden areas into your home.
Outbuildings
Small sheds and outbuildings are included in the treatment. Sheds are a classic redback and huntsman habitat and are often completely missed by competitor treatments.
Outdoor furniture, letterbox, washing line, and wheelie bins
These are the places spiders love most and people check least. We treat outdoor chairs and tables, the letterbox, the washing line, and wheelie bins, because a redback under your garden chair or inside your letterbox is just as dangerous as one inside the house.
Stop Spiders Before They Take Over
Why Perth Homes Need Professional Spider Control
Perth is one of the best places in Australia to live, but its warm climate, dry summers, and bush-adjacent suburbs make it a haven for spiders year-round.
Several species common in Perth are genuinely dangerous. A redback in a letterbox or under a garden chair is not just a nuisance, it's a medical risk, particularly for children and elderly family members. White-tail spider bites can cause significant localised pain and skin irritation. Wolf spiders regularly enter homes through gaps and vents, especially in autumn when temperatures start to drop.
A single treatment that only targets the visible problem is rarely enough. Spiders breed fast, hide in hard-to-reach places, and return to areas where conditions suit them. At Pest M8, we take a whole-property approach to spider control Perth so that you are not just solving today's problem but preventing the next one.

Terence was very knowledgeable and thorough. He even gave us a report for our house. We noted also he didnt leave residue all over windows and walls either which was a nice surprise and different from previous experience with a other pest control company.

Common Spiders Found in Perth Homes
Knowing your local spider species matters. Effective treatment depends on understanding where each species of common spider in Perth hides, how they breed, and how they move through a property.
Redback spider
Identified by the distinctive red or orange stripe on the female's abdomen, redbacks prefer dry sheltered spots: letterboxes, the underside of outdoor furniture, garden pots, sheds, and roof voids. Their venom is neurotoxic.
White-tailed spider
Slender and grey with a distinctive white tip at the end of the abdomen, white-tails are active hunters that don't build webs. They roam at night and are frequently found inside homes, particularly in bedrooms and bathrooms.
Black house spider
Dark grey to black with a distinctive funnel-shaped web, black house spiders are found on window frames, in the corners of eaves, and in brickwork. Their webs are messy and persistent. Bites can cause localised pain and nausea.
Daddy long legs
They are a fixture in Perth homes, found in ceiling corners, garages, sheds, and under eaves. Their loose, tangled webs build up quickly and are a reliable sign that other insects are active nearby.
Huntsman spider
Flat-bodied and large-legged, huntsmen are the spiders most likely to cause a fright when they appear behind a curtain or on a bedroom wall. They are generally not dangerous to humans.
Garden orb weaver
Garden orb weavers are the spiders responsible for the large, circular webs that appear across Perth gardens, verandahs, and outdoor entertaining areas from late summer through autumn.
If you’re unsure what you’re dealing with, we’ll identify activity during treatment and advise accordingly.

Why Spider Infestations Keep Returning
The Source of the Problem Matters
If you have had a Perth spider treatment in the past and the spiders came back within weeks, there is usually a clear reason. Spiders return to properties that offer what they need: shelter, warmth, darkness, moisture, and a food source.
Common reasons spider populations bounce back include:
-
Insect activity nearby - spiders follow their food source, so a property with a high insect population will always attract spiders
-
Cluttered storage areas - roof voids, sheds, and stacked items give spiders ideal undisturbed nesting spots
-
Gaps and entry points - cracks around windows, doors, and pipes allow spiders to enter and re-enter freely
-
Outdoor lighting - lights attract insects at night, which then attract spiders
-
Dense garden vegetation - overgrown plants and ground cover close to the home create a sheltered corridor for spiders to move indoors
-
Incomplete previous treatments - if roof voids, subfloor areas, or fence lines were skipped, the infestation was never fully addressed
A Pest M8 Perth spider control treatment tackles the full cycle, not just the visible webs.
Signs You May Need Spider Treatment
Not sure if you actually need a professional treatment? Here is what to look for:
Persistent webs that reappear quickly after being cleared, particularly in the same spots, indicate an active and established population rather than the occasional wandering spider.
Regular sightings inside the home, especially of multiple different species, suggest spiders are finding your home easy to enter and comfortable to stay in.
Spider bites on family members or pets are the clearest sign that the problem needs professional attention.
Egg sacs are a serious sign. A single female spider can produce hundreds of eggs. If you are seeing silk-wrapped egg sacs in corners, eaves, or under furniture, a treatment should not wait.
High insect activity, particularly flies, mosquitoes, or ants, is a strong indicator that spiders are being actively supported by a food source.
Spiders near entry points or high-traffic areas suggests a widespread presence that requires professional attention.
How Our Spider Treatment in Perth Works
Inspection, treatment, and prevention
01
Property inspection
Your technician will conduct a thorough walkthrough of the property before treatment begins. This includes checking known hotspots, identifying species present, and assessing conditions that may be encouraging spider activity.
02
Targeted application
We apply professional-grade residual treatments to all relevant internal and external areas, including roof voids, subfloor, eaves, perimeter walls, frames, fencing, garden edges, and all outdoor structures and surfaces.
03
Barrier protection
A protective perimeter barrier is applied around the full exterior of the property to stop spiders from crossing back in from surrounding garden and fence areas.
04
Written report and recommendations
Once the treatment is complete, you will receive a full written report covering what was treated, what was found, and any recommendations to support long-term results.
Safe for Families, Pets, and Properties
We understand that having a pest technician treat your home means trusting someone with the safety of your household. That's why our spider control Perth treatments use registered, professional-grade products that are applied by licensed technicians following Australian safety standards.
How to Reduce Spider Activity After Treatment
Simple Property Habits That Help
A professional treatment does the heavy lifting, but a few simple habits will help you get more out of it and keep spiders at bay for longer.
-
Seal entry points - use weather stripping, gap filler, or mesh to close cracks around windows, doors, and pipes
-
Reduce clutter - clear away stacked materials in sheds, garages, and roof voids where spiders like to nest undisturbed
-
Trim vegetation back - keep garden beds, shrubs, and ground cover away from the walls and foundation of your home
-
Clean cobwebs regularly - removing webs and egg sacs discourages spiders from re-establishing in the same spot
-
Adjust outdoor lighting - switch to warm-toned LED bulbs outdoors or move lights away from entry points to reduce the insect activity that draws spiders in
-
Keep outdoor furniture clean - wipe down chairs, tables, and bins regularly, as spiders are drawn to undisturbed, sheltered surfaces
Combining these habits with a regular treatment schedule will give you the best long-term results.

Frequently Asked Questions About Spider Control in Perth
The cost of a spider treatment in Perth depends on the size of your property and the extent of the infestation. PestM8 offers some of the most competitive pricing in Perth without reducing the scope of the treatment. Contact us for a free, no-obligation quote.
Most spider treatments remain effective for three to six months, depending on the products used, the level of existing infestation, and environmental factors such as rain. For Perth properties with ongoing pressure from bush surrounds or neighbouring properties, we recommend a treatment every six months.
Yes, once the treated surfaces are fully dry. Pest M8 uses professional-grade products applied correctly by a licensed technician. We will advise you on how long to keep children and pets off treated areas, and we are happy to discuss any specific concerns before we begin.
The redback spider is the most medically significant species in Perth. Its bite can cause severe pain, sweating, nausea, and may require antivenin treatment. The white-tail spider can cause significant localised pain and skin reactions. The mouse spider and trapdoor spider are also found in WA and carry venom that should be taken seriously. Huntsman and wolf spider bites, while painful, are not generally considered medically dangerous to healthy adults.
For internal treatments, it is best to vacate the property during the treatment and for a short period while surfaces dry, typically one to two hours. Pest M8 will give you specific guidance before the job based on what areas are being treated.
Over-the-counter sprays will kill individual spiders on contact but do not provide the extent of residual protection or coverage of a professional treatment. They also do not address roof voids, subfloors, or the full property perimeter. If you have a genuine infestation, particularly involving redbacks, professional treatment is significantly more effective and safer.
Call or contact PestM8 directly and we will arrange a time that suits you. We aim to respond quickly to all enquiries and can often accommodate bookings within a day or two.
