How Do Termites Get into Your House? Preventing Infestations from the Start

Termites have been chewing through wood for more than 120 million years. These tiny pests have a history dating back to the days when dinosaurs roamed the Earth. Today, termites create billions of dollars in property damage every year. That damage is rarely covered by insurance policies, which is why preventing infestations is so important.

Termite prevention starts with understanding possible termite entry points and signs of termite infestation. Explore the various factors that can contribute to infestations in more detail to guard against these small but hugely destructive pests.

Why Termite Infestations Are a Serious Concern 

There’s a reason termites earned their nickname as “silent destroyers.” Infestations often go unnoticed until the damage is catastrophic. Termites usually eat their way through wood from the inside out, chewing through wood, flooring, walls, and more, while revealing barely more than a hint of their presence.

More than half a million American homes deal with termites every year. The damage they wreak across properties of all types exceeds $5 billion, on average. 

Importance of Understanding How Termites Enter Homes 

If you knew a burglar could easily enter through a side door that didn’t have a lock, you would take steps to secure it, right? That same proactive approach is why it’s so vital to understand exactly how termites might enter your home. Once you assess the vulnerable areas and common entry points, you can take steps to prevent them from becoming unwelcome (and expensive) houseguests. 

Common Entry Points for Termites 

Understanding why, how, and where termites might get inside puts you in a better position to guard against them. The most common termites throughout the region are subterranean termites, which live in underground colonies. They can get into your home in several ways, including by building mud tubes to enter areas higher than ground level. However, that’s not the only way termites gain entrance. 

Foundation Cracks and Gaps 

Cracks in the foundation and openings around utility lines that run from outside to the interior provide termites with easy access. Cracks in the mortar between bricks and holes in concrete blocks can also let termites travel easily through foundation walls.

Wood-to-Ground Contact 

When wood directly touches the soil, termites can easily tunnel right through the soil and into the wood. Depending on where it’s situated, it can open the door to termites invading your home or areas beneath it.

Moisture Problems 

Termites love moisture. They need it to survive and thrive and are drawn to it. That’s why areas with moisture issues, including broken pipes or improper drainage, are often more prone to termite infestations. It’s equally important to ensure proper drainage around the exterior of the home.

Mulch and Landscaping Issues 

Mulch that touches the foundation could give termites free reign to enter your home without any invitation. Likewise, it’s essential to keep trees and shrubbery trimmed 12 inches or more away from exterior walls. Regular mowing and switching to pine needles for mulch can also make your home less attractive to termites. 

Damp and Decaying Wood 

Dead, decaying, and moisture-laden wood is like a termite’s dream food source. This is as true inside, with subfloors, walls, and structural elements, as it is outside. In the yard or landscape, environmental factors can also attract termites to the property and increase the risk of them moving indoors. 

Signs of Termite Infestation 

It often takes a trained eye to spot the damage left in the wake of termite colonies munching their way through wooden structures and elements. However, when you understand what to look for, you might be able to spot it earlier on your own. 

Visible Evidence 

Seeing live termites isn’t the norm because they often stay hidden inside the wood they are consuming. However, when termites mature and are ready to find their mates and start their own colonies, they often swarm near windows and doors. This typically reaches its peak activity in spring, and you might see actual flying termites or find discarded wings on floors and windowsills during this time. 

Damage to Wooden Structures 

Damage to wooden structures might be visible, with signs like blistered paint, areas that look discolored or wavy, and buckling. You can use a screwdriver or another tool to probe exposed wood to see if it has any hollow areas. Try knocking on the wood to see if it sounds hollow, indicating that it is being consumed from the inside out. 

Subtle Behavioral Indicators 

Termites typically remain hidden. They may build tunnels or tubes made from mud to take them safely from their nests to their food sources without exposing them to air, which could dry them out. Termite noises are a much more subtle sign of their presence. Although typically relatively quiet, soldiers will alert the colony to danger by banging their heads on the walls, creating a faint tapping. Additionally, quiet rustling or clicking can indicate termites moving about or feeding. 

Tips for Preventing Termites in Your Home 

Keeping an eye out for signs of an infestation and monitoring potential entry points is just the beginning. Thankfully, you can take additional steps to help reduce the risk of termites. 

Maintain Proper Drainage 

It’s essential to fix plumbing problems promptly and address moisture issues by installing a dehumidifier and maintaining adequate ventilation. Maintain clear gutters and downspouts, flashing that doesn’t leak, and grading that keeps moisture from pooling around the foundation. 

Seal Cracks and Gaps 

Depending on the size of the opening, you might use caulk or a combination of steel wool and caulk. You might also opt to seal things using spray foam, metal screening, hardware cloth, or metal sheeting cut to fit the space. Another option is installing professional exclusion systems. USX Pest Rodent and Wildlife Exclusion Systems offer a permanent barrier for long-term, chemical-free protection from termites, rodents, and more.

Keep Wood and Soil Separate 

Evaluate porch steps and supports, deck framing and posts, door frames, and fencing. Remove any paper, mulch, and other cellulose-containing items or debris from around or near the foundation. Keep firewood stacked 20 feet or more from the home and ensure any wood siding starts at least six feet above ground level. 

When to Consult Professional Pest Control Services 

If you suspect you have termites, it’s critical to move quickly. Termite control isn’t a do-it-yourself proposition. Instead, partner with pest control professionals who can help eliminate the problem and support you in preventing future issues.

The Value of Regular Inspections 

Despite your best prevention efforts, having a trained set of eyes inspect your home annually can provide next-level peace of mind. Professionals know exactly what to look for and often find tiny details that you might miss. The sooner you spot termite activity, the less damage these 24/7 wood-munching insects can do.

Benefits of Professional Treatment 

Termites are difficult to spot and challenging to treat on your own. Professionals undergo extensive training and have the proper equipment to ensure they reach all areas in need of treatment. For maximum success, professional treatment is a must.
