Abstract: A spill resistant insect bait station particularly adapted for use with liquid or gel insecticide consists of a generally cylindrical housing having an open end, a closed end, and a removable end cap assembly adapted for removable attachment with said open end. The housing interior functions as a reservoir for liquid or gel bait formulations, such as attractants and toxicants. Axial apertures formed in the housing ends provide insects with access to the interior of the housing through a series of openings defined in the walls of internal tube and shaft structures. A spiral baffle projects radially outward from the shaft for sealing engagement with the inner wall of the tubular structure to prevent spillage of liquid bait, while defining a passage for insects leading to the liquid bait. A series of offset openings in the shaft and tube walls provide access to the housing interior.
