Mothballs are pesticides.
Pesticides are broadly defined in FIFRA Section 2(u) as chemicals and other products used to kill, repel, or control pests.
Which mothball formulation?
Mothballs can refer to two different chemical formulations: 1,4-dichlorobenzene and naphthalene. Neither chemical is what we could call, biologically friendly.
Are Mothballs Effective?
Mothballs do annoy mammals. However, you have to have high concentrations of the odor in order to achieve the desired effect. The problem is that in many situations, to achieve those odor levels you will be driving yourself and your family out of the house, too. It is extremely common for professional animal damage controllers to be hired to control an animal after the owner discovered that mothballs had NO effect in driving away the problem animal.
There are questions concerning the long-term health effects of mothballs, particularly the benzene formulation. For significant details about the hazards of mothballs visit The National Pesticide Information Center. Other safety concerns? Mothballs are flammable. They burn very well too.
