The answer to 'how did termite get in my house' is that termites can enter a home through even the smallest cracks and openings. They are attracted to the wood in your home's structure and can access it through tiny gaps in the foundation, walls, or roofing. Termites thrive in warm, moist environments and are often drawn to areas with water damage or excess moisture.
If you suspect you have a termite infestation, it's important to act quickly. Signs of termites include mud tubes on the exterior of your home, wood damage, and swarms of winged termites. While some minor DIY treatments may be possible, it's generally best to call in a professional pest control expert to properly inspect, treat, and prevent further termite damage to your home.
