Ants are the most common pest problem reported. These tiny invaders will enter your home or business looking for moisture and an accessible food source. Some ants can cause damage to wood and fabrics. Others might contaminate food and bite or sting. Usually when there is one ant there are many more nearby. Ant colonies can be made up of thousands of ants. These little scavengers can be a difficult for homeowners. If not treated correctly, ants just keep coming back.
