What are the materials and types of objects that have the contamination? "Mothballs" are usually either naphthalene or paradichlorobenzene, but are highly volatile organic chemicals (VOC's). The TLV for p-dichlorobenze is 75 ppm, and napthalene is 10 ppm. You'll need to use organic vapor pesticide-rated cannisters on your respirator, if you use one and a fume hood is recommended as well. Most likely, the best method will be the use of an absorbant to pull out the odor molecules. More information on the objects will be helpful to make more specific suggestions.
