How to Get Rid of Spiders
Spiders are most likely to enter your home in the summer or autumn in search of a warm place to spend the winter. As the weather cools, they venture indoors searching for warmth, shelter, and mates.
The best advice, in general, is to leave them house spiders alone. This can be difficult for people who have a real fear of spiders.
While most common house spiders are harmless and simply a nuisance, leaving unwelcome webs across ceilings, attics, and windows, certain species require more attention. The rise of the False Widow spider (Steatoda nobilis) in Ireland has made spider control sometimes necessary, as their bites can cause painful swellings and minor toxic reactions.

How to Deter and Get Rid of Spiders: Expert Removal & Prevention Tips
While professional pest control can be required for severe infestations or venomous species like the False Widow, you can significantly reduce spider activity indoors by taking key preventative measures. The most effective way to control spiders is to limit their food source, remove hiding spots, and block their entry routes into your home or business,
Follow these proven steps to keep spiders out of your property:
-
Vacuum regularly, high and low - Spiders prefer undisturbed, dark areas. Regularly vacuuming beneath kitchen worktops, behind large furniture, inside fitted wardrobes, and along skirting boards removes hiding spiders, egg sacs, and cobwebs before an infestation can take hold.
-
Remove Webs and Egg Sacs Immediately - Regularly sweep down or vacuum visible cobwebs from high corners, ceilings, and window frames. Destroying webs disrupts their hunting cycle and encourages spiders to migrate elsewhere.
-
Block Entry Points (Spider Proofing) - Spiders enter buildings through minute cracks and openings. Seal gaps in exterior brickwork, fit draught excluders beneath doors, and seal clearances around utility pipework using caulk or expanding foam.
-
Remove Sheltering Sites - Spiders nest outside near buildings before moving inside during the autumn mating season. Relocate firewood piles, compost heaps, garden bags, and organic clutter away from your property’s exterior walls to eliminate key harbourage sites.
-
Adjust Exterior and Interior Lighting - Insects are naturally drawn to bright outdoor lighting, which in turn attracts spiders building webs near entry points. Switch to low-UV or warm LED lights around doorways and keep blinds or curtains closed at night to prevent indoor lights from attracting prey.

Frequently Asked Questions About Spider Removal in Ireland
-
How do I get rid of spiders permanently in my house?
While it is virtually impossible to keep every spider out permanently, you can dramatically reduce their numbers by combining spider proofing with habit elimination. Seal external wall gaps, install door draft excluders, vacuum regularly behind furniture to remove webs and egg sacs, and address underlying pest problems (such as flies or woodlice) that serve as their primary food source.
-
Are False Widow spiders dangerous?
The False Widow (Steatoda nobilis) is the most venomous spider established in Ireland. While they are not aggressive and only bite when threatened or trapped, their bite can cause localised pain, swelling, and redness similar to a wasp sting. In some cases, bites can lead to secondary skin infections or more severe reactions requiring professional treatment.
-
When is spider season in Ireland?
Spider activity in Ireland peaks between late August and October. During autumn, male spiders mature and venture indoors in search of warm environments and females to mate with, leading to a noticeable increase in indoor sightings.
-
Why do I suddenly have so many spiders in my home?
A sudden influx of spiders usually indicates two things: a drop in outdoor temperatures driving them indoors for shelter, or an abundance of prey insects inside your building. If you have an unaddressed issue with flies, silverfish, or carpet beetles, spiders will migrate to your property to feed.
-
What smells keep spiders away?
Essential oils like peppermint, tea tree, and eucalyptus mixed with water can be sprayed around window frames, doorways, and skirting boards to act as a natural repellent. However, while essential oils may deter individual spiders, they will not solve an established infestation or destroy hidden egg sacs.
