The present invention provides a flying insect trap employing a scent-based insect bait to attract flying insects to the trap. Insects can enter the trap through entry pipes in the side of the trap which curve or angle downward once inside the trap. A window of clear plastic or similar material is provided in the top surface of the trap to admit sunlight and draw insects seeking to escape upward and away from the entry pipes. If the entry pipes are made of a dark, opaque material, relatively little sunlight will enter the trap through the entry pipes compared with the clear plastic window, and insects within the trap will not perceive the entry pipes as a possible exit. The trap can be constructed within a removable top cap so that the trap can be supplied with dry insect bait which can be activated before deployment by removing the cap and adding water to the dry bait.
