Interceptor

Product Description

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.

Distributors / Implementing Organizations

Various aid organizations working with BASF, including Red Cross, UNICEF, and Roll Back Malaria

Manufacturing/Building Method

Unknown

Intellectural Property Type

Patent Protected

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

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.
