The present invention discloses devices for a durable insect bait station for biting flies in blood-seeking mode and methods therein. The devices include: an elastomeric membrane for providing access to the bait station, the elastomeric membrane adapted to be permeable to volatile components, and the elastomeric membrane configured to allow easy insect-probe penetration for biting flies in blood-seeking mode； a bait core for providing bait to the bait station, the bait core including: at least one blood-feeding stimulant (BFS) for inducing feeding of the biting flies on the bait core； and at least one insect toxin； wherein the bait core is configured to be substantially in direct contact with the elastomeric membrane； and a support element for attaching the elastomeric membrane and the bait core to a fixed structure. Alternatively, the BFS for inducing the feeding is operative at an ambient temperature below an average mammal temperature.
