How to Get Rid of Spiders

Remove spiders from your home and stop them coming back

All About Spiders

Part of our Pest Control Guide – Created by the team at DIY Gardening

There are over 600 species of spider commonly found in the UK and thankfully very few are poisonous.

Serious reactions to spider bites are incredibly rare in the UK and spiders are generally considered little more than a nuisance.

If you want to know how to get rid of spiders from your home, garage, shed or even your garden, check out these products:

1) Critter Kill Traps

We loved these traps so much that we deployed them in numerous places around the home.

We even used them to get rid of spiders in the back our van – with so many leaves, tree branches and other garden materials in there, spider infestations were a common occurrence.

Each trap is made from cardboard and has a super-strong adhesive on one side, any spider or insect that walks over the trap becomes stuck.

These traps work incredibly well and are, in our opinion, the best way to get rid of spiders.

You can use these traps anywhere that’s dry; in the home, under the porch, in the garage/shed, in a greenhouse, in a vehicle or any sheltered location the garden.

Here’s the best bit: They don’t contain any nasty chemicals so no aerosols, no powder, no fumigation, no nasty chemicals at all. Use them in the kitchen, around vegetable plants, around children or pets, you can place these spider traps anywhere dry.

They’re also 100% recyclable and can be placed in your garden compost bin if you have one.

2) Remove What The Spiders Eat

Spiders eat insects and they can’t get enough them, from moths to flies and bugs, spiders will eat almost any insect they can get their legs on. 

In fact, spiders are one of the best insect control methods out there.

However, if you’re really determined to get rid of spiders, take their food source away.

While chemical insecticide sprays are rarely effective at killing spider infestations, they do remove the food source.

Use household insecticide sprays and fumigators to get rid of silverfish, flys, moths and other insects spiders eat.

Did you know that spiders prefer to consume freshly killed insects? They get their water intake from recently killed prey.

Remove the prey and the spiders will relocate elsewhere.

We have two products that we recommend for you.

The first is a fumigator and the second is a lacquer that can be sprayed around window and door frames as well as ventilation holes, under cupboards and almost anywhere spiders are likely to be found.

CritterKill Smoke Bombs

Smoke fumigators are an effective way to get rid of insects around the home, even ones you can’t see, such as silverfish. 

Just place the tub on an old plate or anything else that doesn’t burn, light the wick and vacate the room for half a day.

The chemical is powerful but becomes inactive after a few hours, so the residue is harmless to pets and children.

While fumigation isn’t a good way to kill spiders, the chemical is designed to kill all known smaller insects, so it’s very effective at getting rid of spiders by taking away their food source. 

You’ll also get rid of any other crawling insects in your home too.

Insecticide Lacquer

Deathlaq is our favourite surface insecticide, and we know from experience that it works incredibly well at deterring insects from coming into the home.

This product comes in a can and once used, the liquid dries to a lacquer that contains a powerful insecticide. This acts as a barrier which insects avoid.

While the manufacturer doesn’t market this insecticide as a spider killer (none are in the UK), it will prevent insects from entering the home if you spray in around window edges, door edges and any other entrances.

We saw a noticeable reduction in both insects and spiders after deploying Deathlaq.

Our CritterKill traps didn’t have nearly as many insects and spiders in them after using Deathlaq.

3) SpiderEx

SpiderEx is an aerosol containing several chemicals that deter spiders, it was originally used by professionals to keep spiders away from CCTV cameras – a long-standing issue with these cameras is they need to be cleaned of webs, sometimes more than once a week.

SpiderEx is now available as a household product for deterring spiders.

Spray the product onto any hard surface such as skirting boards, window frames, doors, in lofts, sheds, garages and greenhouses.

SpiderEx won’t stain, mark or discolour the surface, it was after all designed to be sprayed around CCTV cameras.

4) The Natural Option – Spider Stopper

Spider Stopper is an all-natural product, perfect for use in homes where children and pets are present. Also, use this deterrent anywhere you’re growing fruit and veg, they won’t be affected by Spider Stopper.

This 500ml product contains a natural scent derived from clove and peppermint and is quite pleasant for humans. 

Apply to any surface, this won’t kill spiders but should deter most of them. Reapply every 2 weeks to keep the scent fresh.

5) Create Your Own Spider Deterrent

You can easily create your own pet and child-safe spider deterrent using products readily available online.

If you’d like to have a go, just mix these liquids together and deploy via a handheld sprayer:

  • 3% lemongrass oil
  • 3% citrus juice
  • 3% thyme oil
  • 91% even mix of water, alcohol, vinegar

Feel free to add peppermint and clove juice if you wish. 

All of these ingredients are known spider deterrents and can be found in natural/organic products.

6) Ultrasonic Deterrent

The team here at DIY Gardening previously looked at ultrasonic devices as a way to deter cats from entering a garden. Research by the RSPCA found that when deployed in a garden, the number of cats entrances was reduced by 32%.

Similar devices are on the market and targeted to smaller animals, insects and spiders.

FitFort is one example and has three different modes; one each for different pests and levels of infestation.

Our experience of ultrasonic devices has been mixed, while we’ve observed a reduction in the number of pests, we’re not convinced that they could ever work as a standalone product.

Traps and chemical products are far more likely to get of spiders but if you have an intense fear of spiders, an ultrasonic device could reduce the number of them and is worth a try.

Conclusion

Our favourite products are the CritterKill sticky traps and the surface lacquer. 

The insecticide lacquer stops most of the spiders from entering the property while the traps deal with any that do manage to get through.

The remaining products complement the first two or can be used as natural alternatives.

Do remember that if you remove all the spiders from your home, any insects present won’t have any natural predators.

Spider FAQs

When are spiders most active?

Spiders in the UK are most active and most likely to be found in the home from later summer to mid-autumn as males search for female spiders.

Are spiders in the UK dangerous?

Very few spiders in the UK bite and the venom is exceptionally mild compared to that from spiders found in many other countries. In a few cases, individuals have experienced adverse reactions and infections caused by bites from UK spiders, but these are rare and not the norm.

How many eggs does a spider lay?

House spiders can lay several hundred eggs in a sack and can produce several sacks in a short amount of time. The sacks are suspended in their webs and it takes 2-3 weeks for the spiders to hatch.

What is the best natural way to get rid of spiders?

If you don’t want to use nasty chemicals, try making a spray containing alcohol, vinegar and citrus juice – this has been proven to repel spiders for a few weeks.
