How to Stop Spiders Coming Through Gaps in Windows and Doors

Finding spiders inside your home can become frustrating when they seem to keep appearing around the same windows and doors. In many cases, the problem may not be the spiders themselves, but the small gaps and openings they are using to get inside.

Windows, doors and their surrounding frames can develop gaps over time due to general wear, damaged seals or movement in building materials. Checking these areas can help reduce easy access and make it harder for spiders to enter.

Why Do Spiders Come Through Windows and Doors?

Spiders can enter through surprisingly small openings. Gaps around window frames, spaces beneath doors and damaged flyscreens can all provide potential access points.

There may also be another reason spiders are gathering around entrances. Outdoor lights can attract insects, and insects provide a food source for spiders. Gardens and vegetation close to windows can also create sheltered areas where spiders can remain close to the house.

If you regularly notice webs around windows or doors, it may be worth checking both the entry point and the area immediately outside it.

Check Your Window Frames and Seals

Start by examining the edges of your windows. Look for cracked sealant, gaps between the frame and wall, damaged weather stripping or areas where the frame no longer fits tightly.

Older seals can become brittle and deteriorate over time. Even a small opening can provide an opportunity for spiders and other insects to enter.

Replacing damaged weather stripping or resealing suitable gaps can help improve the seal around the window. However, avoid blocking drainage openings that are intentionally built into window frames, as these are important for allowing water to escape.

Inspect Door Gaps and Flyscreens

Doors are another common access point, particularly if there is a noticeable gap underneath or around the frame.

A simple way to check is to look for visible daylight beneath a closed external door. Damaged door seals, worn weather stripping and gaps around the frame may also need attention.

Flyscreens should be checked for tears and loose sections. A screen that no longer fits properly can allow spiders and insects to pass through. Repairing damaged screens can therefore help reduce unwanted entry without preventing airflow.

Seal Small Entry Points Around the Home

Once you have identified suitable gaps, repair them using materials appropriate for the location. Weather stripping, door sweeps and suitable sealants can help close openings around doors and windows.

Pay attention to areas where different building materials meet, as these can develop small cracks over time. Also check around window frames, vents and other openings near entry points.

Do not seal every opening you find without checking its purpose. Some gaps are designed for ventilation or drainage, and blocking them can create other problems.

Reduce What Attracts Spiders Near Entrances

Stopping spiders from entering is only part of the solution. It is also useful to consider why they are staying close to your windows and doors.

Keep vegetation trimmed back where it is growing directly against windows or external doors. Remove webs regularly from accessible areas and keep outdoor spaces reasonably clear of accumulated leaves and garden debris.

Outdoor lighting can also contribute to insect activity around entrances. Where practical, reducing unnecessary lighting near doors and windows may help limit the number of insects gathering there.

What If Spiders Keep Appearing After You Seal the Gaps?

If spiders continue appearing indoors despite repairing obvious entry points, there may be activity elsewhere around the property.

Spiders can shelter in garages, roof spaces, sheds, garden areas, wall cavities and other less frequently disturbed locations. They may also be entering through gaps that are difficult to identify during a basic inspection.

In these situations, spider control in Sydney services can help assess the property and identify areas that may be supporting ongoing spider activity. Professional treatment may be considered when sightings are frequent, or the problem is difficult to manage through maintenance alone.

Keep Windows and Doors Less Attractive to Spiders

Regular maintenance can make a noticeable difference over time. Check window and door seals periodically, repair damaged flyscreens and clean webs from accessible areas before they build up.

It is also worth keeping an eye on vegetation around the outside of the property and checking for areas where insects are gathering. Addressing these conditions can reduce the food and shelter available to spiders near the home.

These steps will not prevent every spider from appearing, but they can reduce some of the easier pathways and conditions that encourage spider activity.

Take Control of Spider Entry Points

Small gaps around windows and doors can give spiders an easy way into your home. Checking seals, repairing flyscreens, closing suitable gaps and reducing insect activity around entrances can all help minimise the problem.

If spiders continue appearing despite these measures, the issue may extend beyond a single gap or damaged screen. Looking at the wider property and identifying where spiders are sheltering can help determine the most appropriate next step.

Frequently Asked Questions

Can spiders get through very small gaps around windows?
Yes. Spiders can use small openings around window frames, damaged seals and other gaps to gain access to a home.

How do I stop spiders coming under my doors?
Check for gaps beneath the door and around the frame. A suitable door sweep or weather seal can help close the opening while still allowing the door to operate properly.

Do flyscreens help keep spiders out?
Flyscreens can reduce access for spiders and insects when they are properly fitted and undamaged. Tears, loose edges or gaps around the frame should be repaired.

Why do I keep finding webs around my windows?
Spiders may be attracted to windows because insects gather around them, particularly where outdoor lighting is present. Nearby vegetation and sheltered areas can also encourage spider activity.

Will sealing gaps completely stop spiders?
Sealing suitable entry points can reduce access, but it may not eliminate spider activity if there are other entry points or established sheltering areas around the property.
