Flying ants, also referred to as winged carpenter ants, are attracted to sweets, grease, meat and fat. Winged ants also tend to swarm after heavy rain storms. When winged ants emerge from walls, ceilings or crawl spaces, this often indicates a severe carpenter ant infestation.
Early signs of a carpenter ant infestation include the presence of large black ants throughout a home or dwelling. Carpenter ants enter homes through openings in foundation, plumbing holes, cracks and attic vents. They build their nests in structural lumber, foam panels and wall voids. Homeowners can minimize the risk of ant infestations by taking preventative measures such as sealing cracks and repairing plumbing to block the ants' access to water leaks. However, severe infestations often require professional extermination.
