Guideline 20.3: Controls discourage the presence of pests

What controls will discourage growth of molds?

Molds can grow on virtually any substance, providing moisture is present. Controlling indoor moisture is therefore an effective way to prevent mold. Use the HVAC system, air conditioners and dehumidifiers to control temperature and humidity and reduce the relative humidity to levels below 60%.
[For more information on relative humidity see Standard *.]

How does exhibit lighting affect insects?

Some insect species are attracted to bright lights, while others avoid light. In general, keep light levels relatively low in exhibits, and place lights outside a case display chamber.
