As an added service, we offer professional web removal following your spider treatment.
While our treatments eliminate spiders, existing webs will remain unless removed. Our web removal service restores the clean appearance of your home or building by brushing away unsightly webs from eaves, corners, outdoor furniture, and other high-visibility areas.
Perfect for improving the aesthetic of your property after treatment.

We’re often called out for house spraying for spiders for two main reasons:
Unsightly webbing on the exterior of homes, especially on darker weatherboard or cedar-clad houses.
Concerns about white-tailed spiders, especially in areas like Waitakere, which is known for regular infestations.
The good news? Spider control is simple and highly effective—especially when done right.
Absolutely. Spider treatments share a lot in common with our fly control treatments, so it’s ideal to combine them—especially during the summer months.
Controlling flying insects also helps reduce the food source for many web-building spiders, which in turn helps control white-tailed spiders, who feed on them.
Images showing necrotic (flesh-eating) reactions are often attributed to white-tailed spider bites. While there’s still debate among researchers, anecdotal evidence suggests white-tails may be a cause in some cases.
Their venom isn’t considered especially potent.
Reactions may result from bacteria introduced through the bite or individual sensitivity to proteins in their venom and saliva.
Severe reactions are rare but possible, especially in sensitive individuals.
White-tailed spiders typically live outdoors, where they hunt other spiders—especially web builders.
They usually come indoors when their environment is disturbed, such as after:
Gardening
Construction or renovation work
Heavy cleaning or pest treatment outdoors
This temporary displacement often leads to sightings inside the home.
No, that’s a myth.
Also known as cellar spiders, Daddy Long Legs do have venom, but it’s mild and generally harmless to humans.
They can bite, but the bite typically causes only a brief burning sensation, if anything at all.
Their fangs are small, but not incapable of piercing skin.
If you’re dealing with spider issues—especially webbing or white-tail sightings—Pestrex is here to help. Contact our team for advice or to book a treatment that’s safe, effective, and tailored to your home.
At Pestrex, our spider treatments are tailored depending on whether we’re targeting web-building spiders or white-tailed spiders. Each species requires a slightly different approach to ensure long-term, effective results.
For web-building spiders, our treatment focuses on the areas they use to spin their webs and catch prey.
Undersides of gutters and eaves
Around doors, windows, vents, and other entry points
Visible spider webs and external wall surfaces
Outdoor furniture, rubbish bins, and fencing around outdoor living areas
To extend the effectiveness of the treatment, we add a surfactant that offers weatherproofing and UV protection, helping the product withstand outdoor conditions for longer-lasting results.
Targeted application to areas where spiders tend to gather, such as:
Ceiling and wall junctions
Corners
Any additional areas of concern you highlight
White-tailed spiders require a broader treatment strategy, as they are hunters and more mobile than web-building spiders.
Our treatment includes everything in the webbing spider service, plus additional attention to:
Roof spaces
Sub-floor areas
Likely entry points and potential indoor habitats, including:
Wardrobes
Linen cupboards
Other dark, undisturbed spaces
This comprehensive approach ensures we address both active spiders and the environments they prefer.
Whether it’s webbing spiders making a mess outside or white-tailed spiders creeping inside, Pestrex has a solution.
Preparation:
No preparation is required.
Aftercare:
Leave existing spider webs in place for at least 5 days.
This allows the treatment to fully affect the spiders using those webs.
When removing webs, do not wash them off—this may remove the treatment.
Instead, use a dry brush or broom to sweep them away.
Preparation Checklist:
Before your treatment, please:
Cover or store any exposed food (e.g., fruit bowls, leftovers)
Put away clean dishes, tea towels, and paper towels
(Used dishes can remain out if they will be washed soon)
Store personal hygiene items such as toothbrushes, towels, and toilet paper
Cover fish tanks and switch off the pump
Cover or store pet food and water bowls
Pull the duvet over pillows and cover cots or bassinets
You’ll need to vacate the home for at least 4 hours after the treatment is completed.
Aftercare:
On returning, open doors and windows to air out the house for at least 10 minutes
Wipe down all food preparation surfaces
We recommend wearing rubber gloves and avoiding touching your eyes until gloves are removed
If you have any questions or need help preparing for your treatment, the Pestrex team is always happy to assist.
Our treatments use synthetic pyrethroids, which are modelled on natural pyrethrins found in chrysanthemum flowers. These products have been proven safe over decades of use, even in sensitive environments.
All treatments are professionally applied at levels that are extremely safe for both humans and pets. The products are readily metabolised, meaning that if contact occurs, they will pass through the body without accumulating or causing long-term effects.
At Pestrex, your safety is our top priority. We only use trusted, scientifically supported products to deliver effective pest control with complete peace of mind.
Simple, practical tips you can use around your home or business to reduce spider sightings and keep your space clear of creepy crawlies.
