Fall Pest Invasion in Toronto: How to Stop Spiders, Ants & Other Creepy Crawlers from Moving In

One crisp October morning, I park my Insectica Pest Control van outside a home in Toronto. The call came from a panicked homeowner who found webs of spiders in her basement and a trail of ants marching across the kitchen floor. It’s a scenario we see every fall. And we’re not the only ones busy – Toronto’s other exterminators, like Pestend, GreenLeaf, Advantage, and Maple Pest Control, are getting similar calls. Fall pest invasion season has arrived in Toronto – as soon as the temperature drops, spiders, ants, and all sorts of creepy crawlers start looking for warm homes indoors.

Why does this happen? As autumn’s chill sets in, pests that were content outdoors in the summer suddenly seek shelter from the cold. Our cozy houses become prime real estate for them. In fact, fall is prime time for insects to sneak indoors in Toronto, trying to escape the dropping temperatures. In this blog, I’ll explain how to stop spiders, ants, and other unwelcome critters from moving in with you this fall – and share why having the right pest control partner (like Insectica!) can make all the difference.

Spiders on the Move This Fall

Spiders become more noticeable indoors as fall settles in, often skittering out from dark corners in search of warmth. While most spiders in Toronto are harmless (and even helpful by eating other bugs), it’s still unsettling to find cobwebs in your home or a creepy arachnid in the bathtub. They’re sneaking inside simply to escape the cold and find a cozy spot to ride out the winter.

To discourage these eight-legged invaders, remove their hiding places and block their entry. Keep storage areas tidy (spiders love clutter to hide in) and seal up cracks or gaps in walls, windows, and the foundation so they have fewer ways in. Regularly vacuum up any webs or egg sacs you find, and try to keep other insects under control – less prey for spiders means less reason for them to stick around.

Ant Armies Marching Indoors

For many homeowners, ants become surprise intruders in autumn. As temperatures drop, ants – especially carpenter ants – may relocate indoors in search of warmth and food. If you start seeing a trail of ants along your baseboards or a cluster around a windowsill, it could mean a colony has moved in. Carpenter ants are a serious concern because they burrow through wood and can compromise your home’s structure over time.

How do you stop these ant armies? Cut off their access and attractions. Seal any tiny cracks or gaps in your home’s exterior (ants can slip through the smallest crevice). Keep your kitchen spotless and store food in airtight containers – don’t give them an easy meal. Also fix any leaks or damp spots, since ants need water too. If you spot sawdust-like frass (little wood shavings) or consistently find ants indoors, it’s wise to act quickly or call a professional. A small ant problem can grow large before you know it.

Other Creepy Crawlers Looking for Shelter

Spiders and ants might be the main fall invaders, but they’re not the only ones. Other pests will happily slip indoors as the weather cools. Cockroaches, for example, love warmth and will sneak inside through pipes or cracks if they can. Cluster flies often gather in attics or near windows to hibernate over winter, buzzing lazily on warm days. You might also notice earwigs, centipedes, or other insects hiding in basements and bathrooms where it’s damp. (Even mice might chew their way in for shelter and food!)

The strategy for these critters is the same: keep them out and remove what attracts them. By sealing entry points and maintaining a clean, dry home, you’ll send a clear message to all these creepy crawlers that they’re not welcome.

Stop Spiders, Ants & Other Pests: Fall Home Protection Tips

Ready to pest-proof your home? A few proactive steps can make a huge difference in keeping the fall invaders out. Here are some crucial tips:

Seal Up Your Home: Fix or block any potential entryways. Caulk cracks in walls and the foundation, seal gaps around pipes and cables, and repair or replace torn window screens. Don’t forget to install door sweeps on exterior doors – even a small gap is an open invitation.
Keep a Clean, Clutter-Free Home: Crumbs and spills are pest magnets, so clean them up promptly. Store food in sealed containers and use trash bins with tight lids. Also clear out excess clutter (like stacks of boxes or papers) where bugs and spiders love to hide.
Manage Moisture: Many bugs are drawn to moisture. Fix leaky pipes or faucets, dry out damp basements or crawl spaces with a dehumidifier, and ensure good ventilation. A dry home is far less attractive to pests (and prevents mold too!).
Yard Maintenance: Don’t let the outside of your home become a pest playground. Rake up fallen leaves and remove any decaying plant debris near your walls (moist leaf piles attract insects). Keep bushes and tree branches trimmed back so they don’t touch your house. Store firewood off the ground and away from your foundation to avoid inviting ants or other insects too close.
Secure Doors & Windows: Make sure your doors and windows close tightly. Add weather stripping to doors and caulk gaps around window frames. By eliminating these gaps, you’ll keep out not just spiders and ants, but also flies and even rodents.

By taking these precautions, you can significantly protect your home from spiders, ants, and other pests all season long. A little effort now means you won’t be sharing your warm house with unwanted guests when winter arrives!
