A bug-trapping cap comprises at least one radial extension extending radially from an outer periphery thereof. The radial extension includes a hollow interior. The hollow interior and a mouth of a bottle together define a zigzag passage when the bug-trapping cap is mounted to the mouth of the bottle such that the mouth of the bottle is not sealed by the bug-trapping cap. The zigzag passage has a downwardly facing opening to allow entrance of bugs and to prevent entrance of rain.
