A laundry additive such as a fabric dryer sheet formed of a flexible substrate contains an insecticidally effective amount of an insecticide, preferably a pyrethrum, in an amount between about 0.05 and about 10 grams per square foot. Alternatively, the insecticide may be included as a component in a rinse-cycle laundry additive. Such laundry additives are appropriate for use by institutions such as hotels, cruise ships, and nursing homes, hospitals, and shelters in the prevention and control of bed bugs. |
