Termites play a vital role in nature, recycling dead, decaying trees. But they can't tell the difference between a dead tree and the lumber in your home.
Termites tunnel from their home in soil in a constant search for food and water. If they come across your home's foundation while foraging, they'll follow any cracks or crevices and plumbing lines into your home. They may enter through wood in direct contact with soil or by building pencil-sized mud tunnels from ground level to where the house's wood frame begins.
Termites can also enter your home through expansion joints in the foundation and utility and plumbing openings. They only need a opening 1⁄32 inch wide to squeeze into your home.
Termite swarmers look a lot like flying ants. In fact, homeowners often mistake flying ants for termite swarmers and become alarmed. But look closely and you'll see several differences.
