How to remove cobwebs: 5 tricks for ceilings, corners and outdoor areas

In September and October, they seem to appear overnight: grey threads in the corners of the ceiling, behind the curtain rail, around the balcony light and across the cellar window. Autumn is the season when many spiders are fully grown and particularly visible. The good news is that it takes only a few minutes to remove cobwebs – if you use the right tool and avoid the classic mistake of smearing them into the wall.

Here are five tricks for inside and outside the home, and how to make sure the webs do not return a week later.

Why there are more cobwebs in autumn

In late summer and autumn, many house spiders are mature and more active, and some come indoors as temperatures drop. Webs also become more visible: dust sticks to old, abandoned threads and turns them grey.

It helps to know that most spiders in Swiss homes are harmless and even useful, as they catch flies and mosquitoes. You do not need to fight them – removing old webs regularly is usually enough. If you are uncomfortable with a spider, catch it with a glass and a piece of card and release it outside.

1. Telescopic duster for high ceilings

A duster on an extendable pole is the easiest tool for ceilings and the tops of wardrobes.

1. Choose a duster with soft, fluffy fibres or a microfibre head – they catch threads instead of pushing them around.
2. Extend the handle so you can reach the corner comfortably from the floor.
3. Turn the duster slowly in the corner, as if winding up spaghetti.
4. Shake out the duster outside or vacuum it after use.

For very high rooms or stairwells, a lambswool or microfibre head on a long pole is worth the investment.

2. The vacuum cleaner for corners and skirting boards

A vacuum with a soft brush attachment removes cobwebs and the dust around them in one step.

• Use the round brush nozzle, not the hard crevice tool, on walls and ceilings.
• Reduce the suction power on delicate wallpaper.
• Do not forget: behind radiators, under beds, behind the sofa and around window frames.
• Vacuum the corners of the cellar and storage room too, where webs build up unnoticed.

3. Textured plaster and light ceilings: gently does it

Many Swiss flats have textured plaster walls (Rauputz) or white ceilings. Here, cobwebs full of dust can leave grey streaks if you rub.

1. Always work dry – never with a damp cloth.
2. Use a soft duster or the vacuum brush and lift the web away rather than wiping along the wall.
3. For a remaining grey shadow, try a soft brush with light strokes.
4. If a mark remains, leave it rather than scrubbing – rubbing damp dirt into the plaster makes it worse.

4. Windows, frames, blinds and lamps

Spiders like places where insects gather: around lights and windows.

• Windows: Remove webs dry with a brush first, then clean the frame. Our guide on how to clean window frames explains the right method for each material.
• Blinds and shutter boxes: Brush out the guide rails and the top of the shutter box with a soft brush.
• Lamps: Switch off and let the bulb cool before dusting lampshades and fittings.
• Curtain rails: Dust along the top with a duster or vacuum brush.

5. Outdoor areas: balcony, entrance and façade

Outside, cobwebs gather under balcony ceilings, around outdoor lights, in the corners of the entrance and on window grilles.

• Use a soft broom or a long-handled brush to remove webs from balcony ceilings and railings.
• Sweep outdoor light fittings and letterboxes regularly – light attracts insects, which attracts spiders.
• A garden hose on a gentle setting can rinse webs from railings and exterior walls where water is allowed. Check the house rules first and avoid spraying onto neighbours' balconies.
• Do not use a high-pressure cleaner on façades, window seals or wooden elements.

How to keep cobwebs away

You will never have a spider-free home, but you can make it less inviting:

• Dust corners and ceilings every two to four weeks.
• Reduce clutter in corners, behind furniture and in the cellar.
• Keep windows closed in the evening when lights are on, or use fly screens.
• Switch off outdoor lights when they are not needed.
• Some people use scents such as peppermint, but there is little reliable evidence that they keep spiders away – regular cleaning is more effective.

Common mistakes when you remove cobwebs

• Using a damp cloth on walls: Turns dusty webs into grey smears.
• Climbing on furniture: One of the most common causes of falls during cleaning.
• Spraying insecticide indoors: Unnecessary for harmless house spiders and not a substitute for cleaning.
• Forgetting to clean the duster: A dusty tool leaves new marks.
