Spotting a spider nest in your home or garden is never pleasant. It might be tucked away in the corner of a loft, hanging beneath a garden chair, or hidden behind a stack of boxes in the garage. Wherever you find one, it usually comes with a rush of unease — and with good reason. A spider nest, or more accurately a spider egg sac, holds dozens if not hundreds of tiny eggs. When those hatch, you could be dealing with a sudden outbreak of spiderlings.
Most of us don’t mind the occasional spider crossing a wall, but knowing a nest is close by is different. It suggests more are on the way, and unless you act, your quiet space could quickly fill with webs, sacs, and unwanted guests. That’s why understanding what spider nests are, how to get rid of them safely, and how to stop them returning matters so much.
This guide walks you through the whole process: recognising a spider nest, why it’s important to remove it, the safest ways to clear it, natural spider control methods, and steps to prevent infestations. You’ll also find advice on when it’s best to call a professional pest control service.
What exactly is a spider nest?
When people use the word “nest,” they often mean a spider egg sac. Unlike messy cobwebs you see stretched across corners, an egg sac is a compact silk pouch. It’s where female spiders lay their eggs and wrap them in protective layers.
Egg sacs vary in size and shape depending on the species. Many are round or oval, about the size of a pea, though some can be larger. Colours range from bright white to cream, grey, or even brownish tones. Inside, there might be 50 to 300 eggs, tightly packed until they hatch.
Some spiders carry the sac on their body for protection, while others attach it to walls, ceilings, furniture, or outdoor structures. Indoors, you’ll often find them in loft corners, along skirting boards, behind curtains, or under furniture. Outdoors, they’re common in sheds, under decking, or hidden beneath eaves.
Being able to tell the difference between an ordinary web and an egg sac is crucial. A web might just mean one spider is present. A sac means a whole new brood could soon arrive.
Why should you remove spider nests?
You may wonder whether leaving a sac alone is harmless. After all, most spiders in the UK aren’t venomous. But removing spider nests quickly is important for several reasons.
- Preventing infestations: a single sac can unleash hundreds of spiderlings, each capable of spreading through your property and forming new webs.
- Protecting peace of mind: many people feel anxious about spiders. Clearing nests reduces that sense of unease.
- Maintaining hygiene: nests and webs collect dust, dirt, and insects, making rooms feel unclean.
- Avoiding repeat problems: if spiderlings hatch and breed again, you could face ongoing infestations rather than a one-off issue.
While most house spiders in Britain are harmless, species such as the false widow can deliver painful bites. And even if there’s no physical danger, the emotional stress of finding spiders multiplying around your home is reason enough to act.
Where are spider nests usually found?
Spiders choose quiet, sheltered areas where they won’t be disturbed. Indoors, you’re most likely to find nests in:
- Lofts and attics: dark, undisturbed, and full of wooden beams and insulation.
- Basements and garages: clutter, boxes, and corners create perfect shelter.
- Behind furniture: especially heavy wardrobes or sofas rarely moved.
- Curtains and blinds: tucked into folds where fabric meets the wall.
- Storage boxes: particularly cardboard, which provides a rough surface for silk to cling to.
Outdoors, spider nests are often found:
- Under decking, sheds, or garden tables
- Along fences, gates, and walls
- Beneath roof eaves or guttering
- In piles of logs, leaves, or garden equipment
- Hidden in unused plant pots or compost bins
If you spot more than one sac in a small area, it’s often a sign that spiders are breeding actively nearby. That’s when you need to step up your removal efforts.
How do you safely remove a spider nest?
Taking down a nest is about being careful, thorough, and preventing the eggs from hatching elsewhere. Here’s a safe process you can follow:
- Get prepared: wear gloves to protect your hands and long sleeves to cover skin. If you’re working in dusty spaces, use a mask.
- Locate the sac properly: check corners, ledges, and dark spots. Use a torch if visibility is poor.
- Remove with a vacuum: indoors, a vacuum with a hose attachment is the most effective tool. Place the nozzle directly over the sac and suck it up whole.
- Or collect it manually: if you don’t want to use a vacuum, carefully place the sac into tissue or a small container. Seal it tightly straight away.
- Dispose of it securely: put the sac in a sealed bag before placing it in the outside bin. Don’t just throw it on the ground, as eggs could still hatch.
- Clean the surface: wipe the area with soapy water, vinegar, or disinfectant to remove silk traces and discourage re-nesting.
Outdoors, the same method works. Just remember to dispose of the sac properly so spiderlings don’t hatch and spread.
What natural methods work against spider nests?
Not everyone wants to spray harsh chemicals around the home, especially if children or pets are present. Luckily, several natural remedies can help prevent spider nests from forming in the first place.
- Vinegar spray: mix equal parts vinegar and water in a bottle and spray around skirting boards, window frames, and loft corners. Vinegar breaks down spider silk and leaves a scent they dislike.
- Peppermint oil: spiders strongly dislike peppermint. Add 10 drops to water in a spray bottle and mist areas where you often see webs or sacs.
- Other essential oils: eucalyptus, tea tree, lavender, and citronella are all effective. They double as pleasant room scents while working as deterrents.
- Regular cleaning: dusting and vacuuming removes cobwebs and unsettles spiders, reducing the chance of them laying eggs.
- Decluttering: spiders love hiding in piles of clothing, stacked boxes, or garden waste. Keeping spaces tidy limits nesting spots.
Outside, trimming hedges, clearing ivy, and reducing piles of leaves or logs makes gardens less attractive for spider nesting.
When should you call a professional pest control service?
For most households, a vacuum and some preventative sprays are enough. But there are situations where professional pest control is the smarter choice:
- Large infestations: if you find nests in multiple rooms or several outside structures, it suggests a deeper problem.
- Repeat issues: when nests return after you’ve cleared them, it means entry points or hidden areas aren’t being addressed.
- Venomous species: while the UK doesn’t have deadly spiders, the false widow can bite and cause pain or swelling. If you suspect dangerous species, leave removal to experts.
- Commercial or shared spaces: schools, offices, or rental properties may need professional treatment to meet health and safety standards.
A pest control service won’t just remove nests. They’ll inspect your property, locate breeding grounds, and apply safe treatments that provide longer-term protection.
How do you prevent spider nests in the future?
The best way to avoid the stress of finding nests is prevention. Small, consistent steps make your home less appealing to spiders:
- Seal entry points: fill cracks in walls, gaps under doors, and spaces around windows.
- Use draught excluders: these double up as spider barriers.
- Switch outdoor lighting: insects are drawn to bright white light, which attracts spiders. Motion-sensor or yellow bulbs reduce this.
- Keep storage neat: use sealed plastic containers instead of cardboard.
- Maintain regular cleaning: vacuuming corners, lofts, and garages stops spiders from settling.
- Spray repellents weekly: vinegar or peppermint oil sprays around skirting boards and sheds help keep them away.
- Tidy gardens: keep hedges trimmed, wood piles stacked neatly, and compost covered.
With a steady routine, you’ll notice far fewer webs and nests appearing.
Are spider nests dangerous?
Spider nests themselves aren’t harmful, but the sheer number of eggs inside is what makes them a concern. One sac can produce hundreds of spiderlings, and within weeks those young spiders can spread throughout your home.
While most British spiders are harmless, the false widow spider is worth noting. Its bite, though rare, can cause swelling, redness, and in some cases nausea. For most people, it’s more the anxiety and discomfort of seeing spiderlings everywhere that feels dangerous.
So the real risk isn’t the sac itself, but what happens if you ignore it. Left alone, it can multiply your spider problem in a very short time.
Frequently asked questions
Can I just crush a spider nest?
You can, but it’s messy and not always effective. Sealing and binning it is cleaner and safer.
Do spiders come back to the same nest?
No, but they may reuse the same sheltered area. Cleaning and sealing spaces stops them returning.
What’s the difference between a spider web and a spider nest?
A web is for catching food. A nest, or egg sac, is specifically for protecting eggs.
How long does it take for spider eggs to hatch?
Depending on the species, it can be two to eight weeks. Warm conditions often speed it up.
Will removing one nest stop all spiders?
Not always. It’s effective for that group, but other spiders may lay elsewhere. That’s why prevention is vital.
Our Final Say!
Learning how to get rid of spider nests gives you control over a problem that can easily escalate if left alone. A single sac may not look like much, but when it contains hundreds of eggs, removing it promptly makes a huge difference.
By recognising nests, dealing with them safely, and using natural repellents alongside regular cleaning, you can keep your home and garden spider-free. And if infestations ever grow too large, calling in a professional ensures the problem is handled properly.
The key is consistency. Don’t just remove a nest once and forget about it. Keep up preventative steps like sealing entry points, decluttering, and using repellents. That way, you’ll not only deal with today’s nests but also avoid the worry of tomorrow’s.
The relief of knowing your loft, garage, or garden shed isn’t harbouring nests is worth the effort. With a steady routine, you can enjoy a clean, calm, and spider-free home all year round.
