Sowbug/Pillbug Invasion: Exterior Treatment and Exclusion

Massive sowbug (woodlouse) entry into a German home bordering a forest requires exterior control and sealing.

Control Steps

Seal foundation cracks and gaps under doors/windows.
Exterior spray: 1 tbsp lemon ammonia + 1 tbsp dish soap per gallon water. Spray soil around house—kills via digestive/nervous system disruption, safe for plants.
If needed: Pyrethrum/rotenone combo (organic, non-toxic).
