What is the typical moisture threshold that makes an environment favorable for termite activity?

Termites thrive in environments with moisture levels that exceed a certain threshold because they require a damp environment to survive and reproduce. A moisture content above 25% creates ideal conditions for termites to flourish. This level of humidity is conducive to their activity because it supports their need for water and contributes to the decay of wood, which is their primary food source.

Higher moisture levels facilitate the breakdown of cellulose found in wood, making it more accessible for termites. This is why environments that consistently maintain humidity above this threshold are often at higher risk for termite infestations. Additionally, various types of termites, such as subterranean termites, specifically seek out these damp conditions to create colonies and expand their populations.
