When are wooden structures especially vulnerable to termite infestation?

Wooden structures are especially vulnerable to termite infestation during warm, humid months. This is primarily due to the environmental conditions that favor termite activity and reproduction. Termites thrive in warm temperatures, and humidity provides the moisture they need for survival and digestion of cellulose found in wood. During these months, the life cycle of termites accelerates, leading to increased foraging and nesting activities. Additionally, the presence of moisture makes wooden structures more attractive to termites, as it aids in weakening the wood structure, making it easier for termites to penetrate and establish colonies.

The other options indicate conditions that are generally not conducive to termite activity. Low temperatures can inhibit termite movement and reduce their reproductive rates. Extreme dry periods can lead to insufficient moisture, making it challenging for termites to thrive. Heavy snowfall, while it can create a temporary insulation barrier, also lowers temperatures, making it less favorable for termite infestations. Thus, warm and humid months are the ideal conditions for these pests to flourish and pose a greater risk to wooden structures.
