Which condition is least likely to cause termite infestations?

Prolonged dry spells are least likely to cause termite infestations because termites thrive in moist environments. These pests require a certain level of humidity and damp conditions for survival and reproduction. When the environment becomes extremely dry, it becomes inhospitable for termites, making it difficult for them to find the moisture they need. In contrast, wood-to-soil contact, moist environments, and the presence of decaying wood all create ideal conditions for termites, as they provide both moisture and food sources that attract and sustain termite populations. Therefore, when considering which condition is least conducive to termite infestations, extended periods of dry weather stand out as the least favorable.
