Some ants will eat meaty food and other insects. If you are not treating the outside of you home for pests on a regular basis, ants will establish scent trails which will lead into your house. Once these trails are in place, you must use more than just spray to stop them from entering. Structural damage by insects is not limited to termites.
Carpenter ants can damage structures sometimes to a greater extend than termites.
They can excavate wood and create smooth flowing tunnels, weakening a structure. Various insecticides and baits are available over the counter, however, their effectiveness is sometimes limited. Termagon employs and trains technicians in this complex art of ant control.
