Managing the summer
As warmer weather arrives and we open our windows more frequently, many of us notice an increase in spiders finding their way indoors. Fortunately, there are several simple steps you can take to make your windows less attractive entry points without harming spiders or using harsh chemicals.
But why Do Spiders Come Through Windows?
Spiders don’t deliberately target windows, they’re simply looking for:
- Shelter
- Warmth
- Insects to feed on
- Quiet places to build webs
Open windows provide an easy route into the home, particularly during late summer and autumn when many species become more active.
Step 1: Remove Existing Webs
Before applying any deterrent:
- Brush away cobwebs
- Vacuum around the frame
- Remove egg sacs if present
- Clean away dead insects
This removes existing spider activity and food sources.
Step 2: Clean the Window Frames
Dirt, pollen and insects can all encourage spider activity.
Pay particular attention to:
- Window tracks
- Rubber seals
- Window sills
- Corners
A clean window is less attractive to insects and therefore to spiders too.
Step 3: Spray Around Entry Points
Apply your peppermint spider spray around:
- Window frames
- Window tracks
- Window sills
- External brickwork immediately surrounding the window
- Air vents close to windows
Avoid spraying directly onto glass if unnecessary to avoid smears.
Step 4: Keep Outdoor Lighting to a Minimum
Lights attract flying insects. Flying insects attract spiders. If practical:
- switch off unnecessary exterior lights
- use warm-coloured bulbs
- close blinds during the evening
Step 5: Seal Small Gaps
Inspect around the window for:
- cracked sealant
- damaged weather strips
- gaps around frames
Small repairs can dramatically reduce entry opportunities.
How Often Should I Spray Around Windows?
Indoor window frames generally only require treatment every few days.
Outdoor frames exposed to rain or direct sunlight may require more frequent application.
Frequently Asked Questions

Final Thoughts
Spiders play an important role in our ecosystem by helping control insects naturally. Rather than harming them, many of us prefer to discourage spiders from entering in the first place.
Regular cleaning, sealing entry points and applying a peppermint-based spider repellent around windows can all form part of a simple, humane prevention strategy.
