Why are these cities infested with termites?

During swarming seasons, termites seek out food and moisture, however, different types of termites look for different things. Subterranean termites (Rhinotermitidae), need constant contact with soil to reach water and are mostly found in North America, whereas drywood termites (Kalotermitidae) specifically look for dry wood, as their name would suggest. As for dampwood termites (Hodotermitidae and Termopsidae), they look for wood that is extremely humid to establish their colony.

Geographic location contributes to the likelihood that homeowners will experience infestations. Warm weather and constant humidity mean that residents in the south are the most likely to experience termite activity.
