From pantry to pest control: Garlic kills the mood for mosquitoes as well

Phys · · 1180 words · By Karen Guzman
Eco-friendly Pest Control Biological Mechanisms Scientific Innovation

Researchers at Yale University have identified a compound in garlic, diallyl disulfide, that inhibits mating and egg-laying in various fly species and mosquitoes. The study, published in the journal Cell, explains the biological mechanism involving the TrpA1 receptor and suggests a potential path for developing eco-friendly pest control.
