Carpenter ants get their name because they excavate wood in order to build their nests. Their excavation results in tunnels inside wood structures. Carpenter ants range in size from one-quarter inch for a worker ant to up to three-quarters inch for a queen.
Carpenter ants are especially prone to wood that is or has been wet and damaged by mold. Even though these ants first take advantage of wet, decayed wood, they may soon begin excavating channels through dry, undamaged wood. These ants customarily enter buildings and structures through cracks around doors, windows, or through any gaps along exterior walls such as holes for wiring or plumbing. Any foliage or tree limbs touching a house provide bridges for carpenter ants to crawl along to reach areas above ground.
Carpenter ants infest wood sources of all kinds including woodpiles, old tree stumps, landscaping, decks, porches, and the framework of homes. Once a colony of carpenter ants has entered a structure, it often does not take long for them to damage wood through their nest building.
Because carpenter ants require a water source, eliminate sources of moisture or standing water. Keep tree branches and other plants cut back from the house. Sometimes pests use these branches to get into your home. Make sure that there are no cracks or little openings around the bottom of your house. Sometimes pests use these to get into your home. Make sure that firewood and building materials are not stored next to your home. Pests like to build nests in stacks of wood.

Pavement ants get their name because they make their nests in or under cracks in pavement. They can infest structures.
These ants will eat almost anything, including insects, seeds, honeydew, honey, bread, meats, nuts and cheese. These ants live in or under pavement cracks on the outside of structures. On the inside of homes, pavement ants can nest in walls, in insulation, and under floors. The likely harborage area that we have observed is in ground-level masonry walls of the foundation, especially on the side of or near the main heating source in the home.
These ants do not pose a public health risk, but they can contaminate food and should be avoided. Pavement ants often use pipes coming from slabs for access to the inside of structures, through slab expansion joints, and natural openings.
Most types of ants, are attracted to moisture, so elimination of any standing water is essential. Keep tree branches and other plants cut back from the house. Make sure that there are no cracks or little openings around your house. In addition, if build-up of food material such as grease, meat product, sweet substances, bread and other similar organic residue, these conditions need to be cleaned and removed.
