Why do I have Sowbugs?

Sowbug is often seen where there is an excessive humidity, under stones, in dead wet wood, under construction materials, etc. It is quite strong and has the capacity to deeply dig and move in soil. It can use and go through very thin cracks and crevices.

Sowbug is very good to detect high humidity levels. Their presence in structures reveal excessive humidity problems relayed to decaying wood, wet materials, water infiltration or condensation points. Sowbug is more abundant on rainy years. In dryer situations, sowbug tries to find more humid areas such as cracks, foundations, basements, etc.

Signs

Sowbugs will often hide in big numbers in locations where humidity is 70% or higher.
