Seven ways to get spiders out of your home - and expert advice on if they work

By Saffron Otter

Spider season is back again this autumn so you're most likely seeing more of the creepy crawlies in your home at the moment.

While some people will marvel at the beauty of their webs, others will shudder at the sight of them and will desperately try to get rid of them.

Luckily, for the arachnophobes among us, there are a number of different ways to get them out of your home.

British house spiders are very unlikely to harm you, though, and are usually quite small.

Spider expert Dr Geoff Oxford, honorary secretary of The British Arachnological Society, explains that just a dozen or so out of Britain’s 670 spider species have jaws powerful enough to break human skin, and potentially inject venom.

But he stresses they’re not aggressive to humans, and will only attempt to bite as a last resort.

The reason why we're seeing more spiders in our homes this September is because when they reach maturity and come out from their hiding places, they're then in search of a mate.

For Dr Oxford, this is a good thing, as he says spiders are invaluable.

“Spiders do a great job as a natural insecticide, and provide food for numerous other organisms – mammals, reptiles, amphibians, predatory insects and birds,” he enthused.

“Their venom is increasingly being investigated as a source of natural insecticides, and their silk can be used in medicine, for example as the scaffolding for artificial joints. The sheer aesthetic beauty of spiders themselves, and their webs, goes without saying.”

If you're still not convinced, there are many theories on how to persuade them to leave your house - and not by squashing them.

But do they work? Bathroom design expert George Holland from Victorian Plumbing and Dr Oxford outline their thoughts on how to gently encourage spiders to scuttle off elsewhere.

1. Make your own spray

Holland says the key natural ingredient for keeping spiders out of your bathroom and home is citrus, and points out that while supermarkets can charge anywhere from £4 to £11 for ready-made spider repellent, it’s much cheaper and easier to make your own.

He recommends mixing about 20 drops of juice from a citrus fruit like lemon or lime, or essential oils like tea tree, lavender, peppermint or cinnamon, with water in a spray bottle.

Then spray corners of your bathroom or any moist areas that are likely to attract spiders, he advises.

“Taking two minutes to make your own spray using a citrus fruit such as lemon is cheaper, efficient, and it makes your bathroom smell amazing,” Holland says.

But Dr Oxford says there’s no proof this will work.

“Nothing wrong with doing this, but there’s absolutely no evidence that this or any other ‘remedy’ e.g. extract of conkers, will repel spiders.”

2. Take them out in a tumbler

Dr Oxford says that if someone really wants to remove a spider, the best way to do it is to simply put a glass over it, slide a piece of card between the surface and the tumbler to trap the spider inside, and then let the spider go outside at some distance from the house.

But he warns: “The daddy long legs spider and a few other species only live indoors in Britain and to put them outside, especially in winter, will almost certainly kill them.”

3. Use lemon peel rub

“This is a favourite trick of mine,” says Holland.

“Rub lemon peel all over the windowsills or anywhere spiders may perch, like behind the toilet or cabinets. The citrus will repel them and will give your bathroom a nice scent.”

However Dr Oxford says he’s not aware of any evidence that rubbing lemon peel acts as a spider repellent.

4. Seal any cracks and openings around windows and doors

Holland says spiders have to get in our homes somehow, so sealing any cracks or openings around windows and doors will reduce the chances of an initial invasion.

Dr Oxford agrees that this will reduce spiders’ home-making opportunities.

“Reducing the number of cracks and crevices will limit the places in which spiders are likely to set up home – although some, like daddy long legs spiders, don’t use retreats of this kind,” he says.

5. Keep rooms clean and tidy

Holland says spiders hide in corners and small spaces because they don’t like to be in the open, so keeping your home uncluttered and clean can help keep spiders away.

“Keeping rooms organised and clean will reduce the chance of a spider putting up a web, and cleaning will remove the dust and small insects and food particles that attract the spiders inside,” he says.

However, Dr Oxford argues that while having a bare, uncluttered house will certainly reduce the number of places spiders can occupy, there’s nothing to suggest they deliberately come into homes, and he points out they eat living prey rather than food particles.

“There’s no evidence that dust or food particles serve to attract spiders inside,” he says.

6. Citronella air fresheners/candles

While you may want to use your homemade repellent to target specific spider-prone areas, to help keep spiders away from entire rooms, Holland advises using an air freshener or burning a candle containing citronella.

But Dr Oxford is unconvinced, saying he is not aware of evidence it will work.

7. Add spider-repelling plants

“Plants such as mint, lemongrass or eucalyptus will not only elevate your bathroom interior but they’ll help ward off spiders as they hate these kind of aromas,” says Holland.

But Oxford says: “I’m not aware that any plant acts as a spider repellent by exuding a scent. Some plants, in gardens, certainly offer better support for spider webs than others, but that’s not what we’re talking about.”

And as for using mint as a repellent, Dr Oxford points out that several spider species, including the garden spider, often use the leaves of mint species as retreats in which to produce and guard their egg sacs, even though other, non-aromatic, plant species are available.
