Pest crustacean · Armadillidium vulgare / Porcellio scaber
The woodlouse (Armadillidium vulgare) proliferates in damp environments — basements, crawl spaces, masonry joints. Its mass presence often indicates a structural moisture problem.
Woodlice don't bite and don't transmit diseases, but their presence in large numbers signals a moisture or ventilation problem. They feed on decomposing organic matter. Treatment combines drying the premises with a contact insecticide in transit areas.
Questions fréquentes
Are woodlice dangerous?
No, woodlice don't bite, don't burrow under the skin and don't transmit diseases. But their mass presence in living spaces signals a moisture or insufficient ventilation problem worth treating at the source.
Why do I have woodlice in my basement?
Woodlice need high humidity (over 70%) to survive. A poorly ventilated basement with degraded masonry joints or rising damp is their ideal habitat. Drying the premises and a dehumidifier reduce the pressure before any treatment.
Is insecticide treatment effective against woodlice?
A contact insecticide in transit areas (skirting boards, joints, door thresholds) works short-term. For a lasting solution, the chemical treatment must be paired with structural measures: sealing cracks, improving ventilation, treating the moisture source.
