Pest Control

For decades the pest control used carbon disulphide. After two decades of interruption because of its declared toxicity, new procedures were implemented.

All materials go through cold treatment before entering the herbarium.

Cold treatment: two periods of 48 hrs at -180C, being let thaw for 24 hrs in between. The specimens are placed in thick plastic bags, well-sealed. An ordinary freezer is used.

Every c. two years there is a chemical fumigation in each one of the two floors of the herbarium.
