An insect trap including a base having an upper end defining a cavity for receiving a removable bait cup. A main housing defining a plurality of openings is matable to the base in an upright position. The main housing defines a mounting structure for supporting a hanger for supporting an uncoiled roll of flypaper within the main housing. A spacer centers an uncoiled roll of flypaper within the main housing. An upper cap free from openings allowing passage of any incident water through the upper cap is matable with the upper end of the main housing. The insect trap is capable of free-standing outdoor use, outside of any enclosure or overhanging structure, while resisting penetration of rain/precipitation into the main housing. The base, main housing, hanger and upper cap are matable to define a weather-resistant enclosure for suspending flypaper within the main housing above the internal cavity of the base.
