Sniff 'n' Stop products are designed using our patented process that mixes with essential oils to provide the perfect environment to create Magnetic Energy. When pests come in contact with the products, they send out a warning signal to others to stay away, therefore creating a negative ion shield wherever the products are dispensed. Sniff ‘n’ Stop products are applied anywhere you want to keep pests away. Protect your family, home, pets, RV, storage, and outdoor areas from unwelcome guests with a Sniff ‘n’ Stop product designed for every need.
