Which environmental factor is known to increase termite activity in a house?

Leaky roofs are associated with increased termite activity because they create moisture-rich environments both inside and outside of a home. Termites thrive in environments with high moisture levels, as they require water to survive and to aid in the digestion of cellulose, their primary food source. When roofs leak, water can accumulate in wall cavities, ceilings, and attics, fostering conditions that are conducive to termite infestations.

The presence of moisture not only attracts termites but can also weaken the structural integrity of wood, making it more susceptible to termite damage. Problems such as mold and wood decay can arise from excessive moisture, further attracting termites to the affected areas. Thus, a leaky roof serves as a key environmental factor that can significantly boost termite activity within a household.

In contrast, high temperatures, low humidity, and strong winds do not directly create the moist conditions that termites favor for habitation and reproduction. While high temperatures may influence termite behavior, they are less critical than moisture levels in encouraging termite infestations.
