Overview

Toronto homeowners are no strangers to pest problems, but termites are a particularly expensive threat. Unlike ants or cockroaches, termites can cause structural damage before you ever spot a single one. Many infestations go unnoticed for months, even years, because termites stay hidden inside walls, crawlspaces, and foundations. In this blog post, Bugs R Us explains what attracts termites to homes in the GTA, how they spread, and what steps you can take today to prevent an infestation before it starts.

Introduction

Termites don’t make headlines in Toronto the way raccoons or rodents do, but they’re a growing problem in the region. Warm summers, moisture-heavy basements, and older wood-frame homes create the perfect environment for termite colonies to grow. Even new builds aren’t immune. Once these insects find a way inside, they begin feeding on anything cellulose-based: wood framing, floorboards, drywall paper, even cardboard storage boxes.

The scariest part? You probably won’t even notice. Termites work quietly, out of sight. By the time you see signs of damage, the colony may already be mature and extensive. That’s why prevention is key.

In this blog post, we break down the most common attractants that lure termites into Toronto homes. We’ll walk you through specific environmental conditions, materials, and maintenance issues that raise your risk. You’ll also learn how to make your property less appealing to termites and when it’s time to bring in the pros.

Why Do Wood and Moisture Attract Termites?

Every termite colony needs three things: food, moisture, and shelter. Unfortunately, your home often provides all three.

Wood is a termite’s primary food source. That includes framing, support beams, baseboards, and even hardwood flooring. But termites prefer wood that’s soft or already damaged by water. Moisture softens wood fibers and makes it easier for termites to chew through and digest.

Damp basements, leaky pipes, and poor drainage around the home create a termite buffet. Subterranean Termites, the most destructive type found in Toronto, build their colonies underground and tunnel into wood from below. If your home has wood-to-soil contact, like a wooden porch post embedded in the ground or untreated wood near a foundation wall, it’s a major risk factor.

Don’t Forget About the Firewood

When termites need food or shelter, even firewood stored against the side of your house becomes an invitation. Any consistently damp, unsealed wood can attract termites, especially if it’s sitting in dark or shaded areas. If you’ve got rotting wooden fence posts or a forgotten pile of old boards in the yard, those could be the reason termites find your home in the first place.

What Are Common Sources of Termite Access?

Even well-built homes can develop weak points that allow termites in. You won’t see them walking across your floor like ants. Termites squeeze in through hidden gaps and remain out of sight.

Foundation Cracks

Cracks in your foundation might seem harmless, but they’re often wide enough for termites to pass through. These cracks can form naturally over time as your home settles or through seasonal expansion and contraction. Areas where plumbing or utility lines enter your home are also easy entryways.

Improper Sealing

Improper sealing around windows and door frames gives termites another path indoors. Expansion joints, especially where concrete slabs meet, can develop gaps. And don’t overlook structures like porches or decks. Termites can move from one part of your property to another without ever touching open air.

Rest assured, if there’s even one path from the soil to your wooden structure, termites will find it.

How Do Landscaping Choices Affect Termite Risk?

Believe it or not, your garden could be drawing termites toward your home.

Mulch

Mulch is a big culprit. While it makes beds look tidy and helps retain soil moisture, mulch also holds moisture against your foundation and provides a soft wood source for termites to feed on. The more mulch you use, especially if it’s piled too close to your home, the higher the risk.

Ground Covering and Shrubs

Thick ground cover and dense shrubs may seem harmless, but when they trap moisture against your home’s siding or foundation, they create ideal conditions for termite foraging. Even decorative landscaping timbers can cause problems if they’re buried partially in soil.

Over time, landscaping decisions that seem minor can add up to a major termite problem.

How Do You Prevent Termites Through Regular Maintenance?

One of the best ways to keep termites out is by removing the conditions they love.

Start with these key home maintenance tips:

  • Fix leaky faucets, pipes, or HVAC units as soon as they’re noticed
  • Clean gutters and make sure downspouts drain at least 4 feet away from your foundation
  • Remove any wood-to-soil contact, especially under decks or around basements

Rotted wood should be replaced immediately, too. Don’t just patch it or paint over it. Damaged sections act like a neon sign to termite scouts. Likewise, any damaged caulking or loose seals around your home’s exterior should be repaired. For sheds, fences, and outbuildings, use pressure-treated lumber rated for ground contact. It lasts longer and repels termites far better than untreated wood.

Those vents and crawlspaces of yours also need regular checks, as well. We recommend that you make sure vents are open and working, and that crawlspaces stay dry. Even condensation buildup in these areas can lead to increased termite activity.

How Do Seasonal Conditions in Toronto Play a Role?

Toronto has a termite season. It’s long, and it starts earlier than many homeowners realize.

Most termites swarm in the spring. This is when mature colonies send out flying termites to start new nests. If you see flying ants near your foundation or windows, they might actually be termites. The difference is subtle but important.

Sadly, spring isn’t the only period for concern. There’s also summer, too. Summer humidity softens wood and raises soil moisture levels. Fall rains can lead to poor drainage around homes. Even winter isn’t safe if termites have already set up shop inside warm basement walls.

Toronto’s freeze-thaw cycle causes small cracks to form in foundations and sidewalks. These cracks let moisture in—and termites follow. They don’t need a lot of space. If they find a crack the width of a credit card, they can squeeze through and start causing trouble.

Snow melt and improper drainage in early spring also create soggy soil around the foundation. That moisture is exactly what termites need to thrive and spread.

What Are the Best Termite Prevention Tips for Homeowners?

Want to keep termites away for good? Here are some of the most effective strategies:

  • Store firewood at least 20 feet from your home
  • Keep mulch thin and no closer than 12 inches from your foundation
  • Seal cracks, gaps, and entry points as part of your seasonal home inspection
  • Inspect wooden fences and landscaping timbers for soft spots or mud tubes
  • Regularly check basement walls and utility access points

Lastly, don’t forget about storage. Cardboard boxes in a damp basement are major termite magnets. A smart trick is making the switch to plastic bins with tight-fitting lids that you can keep off the ground.

When Should You Call a Professional Termite Exterminator?

Some termite problems are obvious. You might spot thin mud tubes running up your foundation or find soft, hollow-sounding wood when tapping a baseboard. But most infestations stay hidden. Termites work silently, often deep within your walls or beneath your flooring, where signs of their presence don’t appear until serious damage has already been done. That’s why a professional inspection is crucial, even when there are no visible red flags.

Trained termite exterminators rely on specialized tools and knowledge that homeowners simply don’t have. Moisture meters, thermal imaging cameras, and years of experience help them detect early-stage infestations. If an infestation’s detected, they go after the colony itself with the help of modern products like Altriset.

Altriset is a termiticide that stops termites from feeding within hours, then spreads throughout the colony as termites groom and interact with each other. Because Altriset is non-repellent, termites don’t detect it. They walk right through it and bring it back to the nest, where it quietly eliminates the population from within. This method offers enduring results, too. Field studies show up to nine years of residual protection thanks to Altriset.
