Mothballs are used to kill moths when storing clothing and other items in airtight storage containers. Mothballs are not intended for use outdoors, in crawl spaces, in attics, on floors or carpets, vehicles, with mattresses or furniture to keep away unwanted animals, rodents, pests, and snakes. Improper use of mothballs like any other chemical product, is not safe, and can result in odors.One common misuse of mothballs is their placement in attics to repel squirrels and other unwanted animals. The mothballs, which are generally made of Naphthalene or Para dichlorobenzene, produce vapors that are heavier than air and can drift downward into living areas. The resulting odors can be intolerable and overexposure to the vapors can result in health hazards.Smelleze® Mothball Deodorizer Pouch eliminates mothball fumes resulting from improper use and for products that don"t dissipate naturally and quickly. Smelleze® will remove mothball odors faster without masking them with fragrances, complement existing ventilation systems, and create a safer environment. For a breath of fresh air, hang one or more reusable Smelleze® pouches near the odor and place on or inside return air ducts and smell the difference. Use one pouch per area or for every 150 sq. ft. To rejuvenate, place outdoors in sunlight for a day and reuse. Replace when rejuvenation does not help. Smelleze® can work for years so it is very cost effective.
