Thanks to you, I won my case at Régie du Logement. If I had known before that certifying the accommodation 24 hours before the arrival of my new tenant was acceptable proof, because of repeated infestation. The documents and videos you have given me have proved the safety of housing before the arrival of the tenant, essential as proof for a cause of bed bugs. So I was released from all responsibility. Detection fees are minimal compared to the cost of multiple extermination.
