Eave Tubes: Protecting households against malaria mosquitoes

In2Care Eave Tubes are a new malaria control product that block mosquitoes from entering the house and effectively kill them with special insecticide-laced netting. The easy-to-install Eave tubes and removable gauze inserts are placed in the wall under the roof of houses where they attract malaria mosquitoes at night, block them from entering the house, and contaminate them with a lethal dose of insecticide. Eave Tubes have been used successfully in remote rural areas and are suitable for the majority of African house styles. Research in Tanzania, executed under our EU-FP7-funded MCD Project, has proved that window screening and installation of In2Care Eave Tubes reduce the number of indoor mosquitoes by up to 90%. In2Care’s patented charged netting technology successfully kills even insecticide-resistant malaria vectors. Scientific findings show that a reduction in infectious mosquito bites of >90% can be achieved when covering only 70% of all houses with Eave Tubes.

In2Care is the designer, developer, IP owner and manufacturer of Eave Tubes, and has successfully developed low-cost and scalable processes for mass-production, installation, insecticide treatment and recycling. In2Care Eave Tubes offer significant benefits over other tools like indoor residual spraying (IRS) and bed nets:

  • Protects the entire household non-stop
  • Low-cost and scalable design; easy-to-install & retreat
  • Effectively kills insecticide-resistant mosquitoes
  • Deploys 100 x less insecticides/house than IRS
  • Roof-level insecticide application reduces risk for human exposure
  • Ventilates the house & increases indoor comfort
  • Uses natural airflow as mosquito lure
  • Blocks (also other) insects from entering the house

 

Eave Tubes are being reviewed by the WHO Vector Control Advisory Group as a new malaria vector control paradigm. To generate the needed scientific evidence, In2Care is collaborating with other institutes and executing a large epidemiological field trial in Ivory Coast. This work falls under the Project entitled “Transition of Eave Tubes from Concept to Implementation” for which our academic partner Penn State University has received a grant from the Bill & Melinda Gates Foundation. In total, 3,022 households in 20 villages have received Eave Tubes and window screening early 2017. This was achieved with local trained workers and customized low-cost installation tools designed by In2Care. Eave Tube netting inserts are treated with (WHO-approved) mosquito-killing insecticides, and the impact on malaria transmission will be measured by the project scientists during the next 2 years.

In collaboration with the Human Development Innovation Fund (HDIF) Tanzania and our local research partner the Ifakara Health Institute, In2Care is also undertaking a large-scale field evaluation of Eave Tubes in Tanzania. In total, 1,500 houses in the Dar es Salaam and Morogoro regions have received In2Care Eave Tubes. The local research team is assessing social acceptance and entomological impacts. In2Care is working on exploring business models for scaling this intervention and making the product available and affordable for the local communities. For more information: watch this video.

Low-cost

One-off Tube installment & low-cost mass-produced inserts that can be recycled

Effective

Protects the entire household and effectively kills even insecticide-resistant mosquitoes

Safe

Uses small amounts of safe insecticides beyond the reach of house occupants.

Novel design

Eave tubes deploy robust netting inserts designed to fit in standard 6-inch PVC tubes. Inserts are made from strong, yet flexible plastic material and can be mass-produced via injection-moulding. Their design enables easy handling and placement of inserts into the wall tubes from the outside of the house.

Resistance-breaking

Eave tube netting uses In2Care’s patented innovative electrostatic coating technology to bind insecticides and transfer high doses to mosquitoes that make contact with the gauze. We showed that this is very effective against all mosquito species, even the ones that have become highly resistant to chemical insecticides. Eave tubes can therefore provide a resistance breaking tool against malaria vectors.
