Staying Spider-Safe This Autumn in Christchurch: What You Need to Know
As autumn settles over Christchurch and the wider Canterbury region, local homes often become a refuge for spiders seeking warmth. While most species are harmless—and even helpful—some can bite, and others are of special ecological importance. Understanding which spiders you’re seeing and how to manage them is essential for a safe and spider-wise season.
Common Spiders Found in Christchurch Homes
- Grey House Spider (Badumna longinqua)
Common in sheltered parts of homes like eaves and sheds. Builds thick, messy webs in corners. - White-Tail Spider (Lampona cylindrata)
Active indoors in cooler months. Known for its wandering nature and distinctive white-tipped abdomen. Bites may cause irritation. - Vagrant Spider (Uliodon spp.)
A large, fast-moving native spider that can look intimidating but is not considered dangerous. Often found at night on walls or floors, especially in rural homes or near gardens. - Garden Orb-Weaver (Eriophora pustulosa)
Generally stays outdoors but may move closer to homes in autumn. Builds large, circular webs and is not harmful to humans. - Daddy Long Legs (Pholcus phalangioides)
Frequently seen hanging in webs indoors. Harmless and helpful in controlling other insects. - Katipō Spider (Latrodectus katipo)
New Zealand’s only venomous native spider. The katipō is threatened and protected, typically found in coastal dune habitats. Rarely seen in Christchurch, but important to be aware of, especially near beaches. If bitten, seek medical help immediately.
Note on the Katipō Spider
The katipō is a nationally threatened species under New Zealand’s Wildlife Act. It plays an important ecological role and should be left undisturbed if encountered. While it is capable of delivering a venomous bite, katipōs are shy and bites are extremely rare. Habitat loss, human interference, and invasive species have all contributed to its decline. If you believe you’ve seen one, especially outside its known range, you may wish to report it to the Department of Conservation (DOC).
Why Spider Control is Important This Autumn
With temperatures cooling, spiders are more likely to seek shelter inside homes. If you’re noticing a rise in spider activity, it could be a sign that your home is also attracting other pests. To avoid a full-blown infestation, it’s important to stay on top of your pest control. If you need help, trusted spider control experts in New Zealand can assist with professional services to keep your home spider-free. Learn more about spider control in Christchurch.
Signs of a Spider Problem
- Visible webs in corners, behind furniture, or in attics
- A surge of spiders, particularly near food or water sources
- Small egg sacs, often hidden in unnoticed corners
- Spiders emerging from clothes or shoes, especially in autumn
If you’re finding more spiders than usual or encountering other pests, like cockroaches or rodents, it’s a sign you may need professional help. Keep your home protected with regular checks and treatments.
How to Keep Spiders Out This Autumn
- Seal Up Cracks and Gaps
Check around windows, doors, and where pipes enter walls. Use silicone caulk or weather stripping to block access. - Clear Clutter Inside and Out
Cardboard boxes, piles of clothing, and woodpiles are spider hotspots. Declutter garages, wardrobes, and storage spaces. - Vacuum Regularly
Especially in corners, along skirting boards, and behind furniture—where spiders often nest. - Use Natural Deterrents
- Peppermint oil: Diluted and sprayed near baseboards and entry points.
- Vinegar spray: Helps repel spiders when used on windowsills and around door frames.
- Citrus peels: Place dried lemon or orange peels in known spider-prone areas.
When to Call for Professional Help
If spiders are becoming a regular issue indoors or you’re unsure whether a species is harmful or protected, it’s best to call a licensed Christchurch pest control professional. They can help:
- Identify native versus introduced species

Autumn Pests You Shouldn’t Ignore
Spiders aren’t the only pests that become more active as the weather cools. Other pests, such as cockroaches, fleas, and silverfish, may also seek warmth and shelter indoors. These pests can be harder to control on your own. If you’re dealing with any of these unwanted visitors, reach out to a pest control expert for safe and effective treatments.

Spiders are a natural part of life in Canterbury—but you don’t have to share your home with them. Autumn is the ideal time to spider-proof your home before winter sets in. Simple steps like sealing gaps, reducing clutter, and using natural deterrents can make a big difference.
