Spatial Repellents

The Prevention of Vector-Borne Diseases

The Spatial Repellents research program, sponsored by the Bill & Melinda Gates Foundation and lead by researchers, Nicole L. Achee and Neil F. Lobo, focuses on the prevention of vector-borne diseases, transmitted through the bites of infected mosquitos. Spatial repellents are designed to release volatile chemicals into the air to reduce mosquito-human contact.

Spatial Repellents

Spatial repellents represent a new paradigm for vector control, causing insects to move away from the area, or inhibiting their attraction and/or feeding. This is different from traditional chemicals intended to kill mosquitos.

Study Sites

Evaluation of the ability of a spatial repellent to prevent infection was conducted in two locations—Iquitos, Peru for dengue and Sumba Island, Indonesia for malaria. Human blood samples and mosquitos were collected and analyzed.
