Beverly learned that their situation could have been avoided if Derik read and followed the label
directions on the mothball products, instead of listening to what his neighbor said. The NPIC
Specialist discussed with Beverly that the product Derik used was not registered by the Environmental
Protection Agency to repel or kill rats. Rather, it was intended to kill clothes moths and
their eggs and be used only in garment bags, storage closets, and airtight containers.
Beverly learned that mothballs are pesticides that come in a solid form, but they volatilize–
changing slowly into a gas. Mothballs produced in the U.S. contain one of two active ingredient
chemicals: naphthalene or paradichlorobenzene. Exposure to large quantities of naphthalene
or paradichlorobenzene can lead to headaches, nausea, vomiting, diarrhea, or eye and nose
irritation and coughing. Furthermore, if exposed for an extended duration, they can lead to more
serious effects like liver and kidney damage.
Beverly was interested in learning how she could reduce the gas the mothballs were producing
in their home. The NPIC Specialist discussed a number of steps she could consider, including
removing the mothballs and ventilating by opening the doors and windows. The label directions
instruct users to avoid skin contact with the mothballs. Therefore, it is important that Beverly
wear gloves when removing them. To reduce further exposure, Beverly and Derik could leave
their home while ventilating and, if needed, use a fan to increase the air circulation. Instructions
on how to properly dispose of the mothballs can be found on the label or be provided by contacting
a local household hazardous waste program.
The NPIC Specialist reminded Beverly to always Read the Label First before using a pesticide
product in order to determine where it can be used, what pests the product will control, and how
to use it correctly.
If someone breathes or ingests a pesticide or gets it on their skin or in their eyes, read the first aid instructions on the product label to determine which steps to take next. Contact your local Poison Control Center (800-222-1222) for emergency medical treatment information or call your doctor.
