ZeroFly® Storage Bag is a storage bag with insecticide incorporated to prevent damaging pest infestations. It reduces the loss of seeds or grains that can be consumed, stored for security, or sold for optimized prices. It is said to be free of the hazards associated with fumigation or the potential for pesticide residues that come from inaccurate insecticide spraying. The insecticide is incorporated into individual fibers of the bags, which provides a killing action before insects can infest the grain or seed packed in the bag.

Zero Fly Storage Bag is not toxic for food consumers, operators, or the environment.
The product uses Deltamethrin as active ingredient. The active ingredient is incorporated into the yarns and slowly released onto the surface, protecting the bags' content continuously.
The user should ensure the bag is kept clean by occasionally using a soft broom to avoid dust building on the surface.
Users can purchase additional bags from the manufacturer to replace damaged bags or bags older than recommended lifecycle.
The product will remain effective for 2 years depending upon environmental conditions. At the end of a lifetime or physical integrity, it should be disposed of following local guidelines on plastic waste disposal. It could be recycled into products that have limited human contact.
Manufacturer Specified Performance Parameters
- Affordable: very competitive price and reusable many times over 2 years
- Environmentally friendly: no need to fumigate and use chemicals during storage
- Safe: reduces pesticide residues commonly found in grain and seed and decreases the risk of aflatoxin and mold build-up
- Effective: proven global efficacy against key insect pests, including Weevil and Larger Grain Borer, even in the most infested conditions
- Durable: proven to last for 2 years even under the toughest environments
- Tailored to individual needs: available in any size from 10 to 1000 kg and in any color with customized prints
Vetted Performance Status
The product has been tested by different independent laboratories. At the Natural Resources Institute, University of Greenwich, Chatham, Kent the Khapra beetle (Trogoderma granarium) and Indian meal moth (Plodia interpunctella) adults were exposed to ZeroFly® Storage Bag samples for up to 72 hrs. Knockdown occurred at one hour and insects were dead after 24 hours. 100% mortality was observed for larvae at the end of the observation period of 14 days. Field tests were also conducted in several countries, results of a study in Ethiopia can be seen in the image, showing significantly less damage in the kernel with ZeroFly storage bags. Tests by several international institutes concluded that the bags are “effective,” insects are killed, their entry into the bags is prevented, and a ‘community effect’ is provided, by reducing insects population in the storage area.
It is not toxic for food consumers, operators, or the environment, Personal Protection Equipment (PPE) such as gloves is recommended to ensure the operator's safety. Depending on the concentration of Deltamethrin it can produce cold burning, numbness of the skin, headache, heartburn, and skin spots It has a “Food safe” classification under US & EU regulations.

Compliance with regulations
Research claims that residue levels of Deltamethrin on the stored commodities are "below the most stringent standard globally." The active ingredient, Deltamethrin, is a Food and Agriculture Organization (FAO) and World Health Organization (WHO) approved pesticide for controlling insect pests.
