An unsuccessful exterminator operation triggered a roof truss fire on a detached house in Kronberg im Taunus, causing a great deal of property damage. According to initial findings, the fire was caused by the improper removal of a wasp nest using a “smoking method”, the police said on Monday evening. As a result, the entire roof structure of the house in the Schönberg district caught fire, and the fire then spread. Overall, property damage was between 150,000 and 300,000 euros.
