An insect bait-and-switch liquid delivery apparatus for the control of insects. The apparatus includes a reservoir defining a first chamber containing liquid bait attractive to an insect and a second chamber containing liquid active toxic to an insect, a first feeding station in the first chamber for making liquid bait available to an insect, a second feeding station in the second chamber for making liquid active available to an insect, a passageway interconnecting the first and second chambers, and an access port disposed to initially prevent or limit access of an insect to the second feeding station during an initial feeding period and to subsequently enable access to the second feeding station via the passageway after the initial feeding period. In one embodiment, the access port is located beneath the surface of the liquid bait, and in another embodiment the access port is located above the surface of said liquid bait.
