Interceptor is a long lasting mosquito net.
The Interceptor is a Long-Lasting Insecticidal Net (LLIN) that knocks down, kills, and repels mosquitos as they come in contact with the net for up to 4 years and 25 wash cycles.
Target SDGs
SDG 3: Good Health and Well-Being
Target Users (Target Impact Group)
Household, Public Sector Agencies, NGOs
Distributors / Implementing Organizations
Red Cross, UNICEF, and Roll Back Malaria
Competitive Landscape
Direct competitors include PermaNet 2.0 and Olyset Net.
Manufacturing/Building Method
Unknown
Intellectural Property Type
Patent
User Provision Model
Aid organizations can purchase the nets directly from BASF. The aid organizations will then distribute the nets to the target beneficiaries in their own manner.

Design Specifications
Mesh net coated with alpha-cypermethrin using a polymer binder. The binder attaches the active agent to the binder such that the active ingredient remains evenly distributed across the surface for years. How the net works: 1) Net fibers coated with alpha-cypermethrin 2) Mosquito makes brief contact with the net 3) Mosquito is paralyzed and "knocked down" 4) Mosquito dies within minutes
Technical Support
BASF video about malaria
Replacement Components
Holes can be patched with local materials, although the insecticide will no longer be present on that spot.
Lifecycle
About 4 years. The net is tested to remain fully functioning after 20 wash cycles.
Manufacturer Specified Performance Parameters
Tunnel test: 80% mortality & 90% blood feeding inhibition after 20 washes. Cone Bioassay Test: 80% mortality & 95% knockdown after 20 washes
Vetted Performance Status
100% knockdown at one-hour post exposure 100% prevention of blood feeding after 20 washes Median time to knockdown: 6 minutes Nets washed 20 to 25 times still meet or exceed performance standards for LLINs with high efficacy
Safety
No hazards listed
Complementary Technical Systems
BASF nets are most effective when used in combination with other malaria control products.

Compliance with regulations
Exceeds the WHO Pesticide Evaluation Scheme requirements for long-lasting insecticidal nets. Nets washed 20 to 25 times still meet or exceed performance standards for LLINs with high efficacy"
Other Information
The Interceptor has been evaluated by the World Health Organization Pesticide Evaluation Scheme (WHOPES) and the Innovative Vector Control Consortium through both lab testing and field studies. Field studies have been conducted in Liberia, India, and Western Uganda.
